PRIVATIZATION AND NIGERIA ECONOMY (A CASE STUDY OF PHCN)

CHAPTER ONE: INTRODUCTION

1.1 Background of the Study

Privatization is the process of transferring ownership and control of state-owned enterprises (SOEs) from the public sector (government) to the private sector. Privatization can take various forms: (1) asset sales (selling government-owned assets to private investors); (2) public share offering (selling shares of a state-owned enterprise on the stock exchange); (3) management contracts (private management of government-owned assets); (4) concessions (private operation of government-owned assets for a specified period); (5) liquidation (selling assets piecemeal and closing the enterprise). Privatization is typically motivated by the belief that private sector ownership and management lead to greater efficiency, productivity, innovation, and customer service than public sector ownership (Megginson and Netter, 2001). (Megginson and Netter, 2001)

The theoretical rationale for privatization is grounded in several economic theories. Property rights theory suggests that private owners have stronger incentives to maximize profits and minimize costs than public managers, who face weaker profit constraints. Public choice theory suggests that public enterprises are subject to political interference (e.g., employment for political supporters, subsidies to favored groups) that reduces efficiency. Agency theory suggests that the principal-agent problem is more severe in public enterprises because there is no residual claimant (shareholder) to monitor managers. Competition theory suggests that privatization often accompanies liberalization (opening markets to competition), which drives efficiency gains (Megginson and Netter, 2001). (Megginson and Netter, 2001)

Nigeria’s privatization program began in earnest in 1988 with the establishment of the Technical Committee on Privatization and Commercialization (TCPC). The program was motivated by the poor performance of state-owned enterprises, which had drained government budgets through subsidies, bailouts, and inefficient operations. Many SOEs were characterized by overstaffing (political patronage), underinvestment, poor service quality, corruption, and lack of accountability. Subsequent waves of privatization were managed by the Bureau of Public Enterprises (BPE), established in 1999, and the National Council on Privatization (NCP), chaired by the Vice President (BPE, 2020). (BPE, 2020)

The Power Holding Company of Nigeria (PHCN) was the state-owned monopoly responsible for electricity generation, transmission, and distribution in Nigeria. For decades, PHCN was a symbol of public sector inefficiency: it generated far less electricity than needed (peak generation of 4,000 MW versus demand of over 20,000 MW), suffered frequent grid collapses, had high transmission and distribution losses (over 30%), collected low revenue (poor billing and collection), and was overstaffed (over 45,000 employees). PHCN required continuous government subsidies and bailouts, draining the national budget (CBN, 2010). (CBN, 2010)

The privatization of PHCN was a landmark event in Nigeria’s economic reform history. In 2005, the National Council on Privatization (NCP) approved the restructuring of PHCN into 18 successor companies: 6 generation companies (Gencos), 1 transmission company (TCN – remained state-owned), and 11 distribution companies (Discos). The privatization process was completed in 2013 when 15 successor companies (5 Gencos and 10 Discos) were sold to private investors. The federal government retained ownership of TCN and the Niger Delta Power Holding Company (NDPHC) (BPE, 2020). (BPE, 2020)

The objectives of the PHCN privatization were ambitious (BPE, 2020). (BPE, 2020)

Increase electricity generation: From 4,000 MW to 10,000 MW within 3-5 years, and eventually to 20,000+ MW.

Improve reliability: Reduce grid collapses, reduce downtime, provide 24/7 electricity to industrial and residential customers.

Reduce losses: Reduce transmission and distribution losses from 30%+ to industry standard (10-15%).

Improve revenue collection: Implement metering, reduce billing losses, reduce outstanding receivables.

Reduce government subsidies: Eliminate budgetary allocations to PHCN, free funds for other priorities (education, health, infrastructure).

Attract private investment: Mobilize private capital for generation, transmission, and distribution infrastructure.

The PHCN privatization was part of a broader economic reform agenda under Presidents Olusegun Obasanjo (1999-2007), Umaru Musa Yar’Adua (2007-2010), and Goodluck Jonathan (2010-2015). Other privatizations included NITEL (telecommunications), NIPOST (postal services), NPA (ports), and various banks, hotels, and manufacturing firms. The telecommunications privatization (leading to MTN, Glo, Airtel, 9mobile) was successful, leading to a dramatic increase in mobile phone penetration (from <1% to >90%). The power sector privatization, however, has had mixed results (BudgIT, 2021). (BudgIT, 2021)

The impact of privatization on the Nigerian economy is a subject of intense debate. Proponents argue that privatization improves efficiency, productivity, service quality, and fiscal sustainability. They point to the telecommunications sector as a success story. Critics argue that privatization can lead to job losses, price increases for consumers, asset stripping (selling assets for short-term gain), and concentration of wealth in the hands of a few (connected investors). They point to the power sector as an example of failed privatization (Okonjo-Iweala, 2012). (Okonjo-Iweala, 2012)

The performance of the privatized PHCN successor companies has been mixed. On the positive side: generation capacity increased from 4,000 MW in 2013 to 7,000-8,000 MW in 2023; some Discos have invested in metering and network upgrades; private management has reduced overstaffing; and the government no longer subsidizes PHCN operations. On the negative side: generation is still far below target (20,000+ MW); transmission constraints (TCN, still state-owned) limit distribution; distribution losses remain high (20-25%); tariff increases have been politically contentious; and many customers still do not receive 24/7 electricity (BudgIT, 2021). (BudgIT, 2021)

Several factors have limited the success of the PHCN privatization (World Bank, 2019). (World Bank, 2019)

Transmission bottleneck: TCN remained state-owned and underfunded, limiting the ability to evacuate power from Gencos to Discos. Transmission constraints are a major bottleneck.

Gas supply constraints: Many Gencos are gas-fired but face gas supply interruptions due to pipeline vandalism, gas price disputes, and insufficient gas infrastructure.

Tariff challenges: The government has been reluctant to allow cost-reflective tariffs (tariffs that cover costs and allow reasonable profit), fearing political backlash. Low tariffs reduce Discos’ revenue and incentive to invest.

Distribution losses: Many Discos have not invested sufficiently in metering, network upgrades, and theft reduction. Estimated and billed (EB) meters, estimated bills, and energy theft remain problems.

Political interference: Despite privatization, government officials still interfere in Discos’ operations (e.g., directing reconnection of defaulting customers, opposing tariff increases).

Debt: Discos inherited significant debt from PHCN and have accumulated additional debt due to low collections and high losses.

The Nigerian economy is heavily dependent on electricity. Poor electricity supply has been estimated to cost the Nigerian economy billions of dollars annually in lost output, idle capacity, and alternative power generation (generators). Manufacturing firms rely on expensive diesel generators; small businesses incur high energy costs; households spend significant income on fuel for generators. Improved electricity supply through successful privatization could transform the Nigerian economy (World Bank, 2019). (World Bank, 2019)

The COVID-19 pandemic (2020-2021) affected the power sector and the economy. Lockdowns reduced electricity demand from industrial and commercial customers; Discos experienced collection challenges; gas supply was disrupted; and government focus shifted to pandemic response. The pandemic highlighted the vulnerability of the power sector and the need for further reforms (Ogunyemi and Adewale, 2021). (Ogunyemi and Adewale, 2021)

The Nigerian government has implemented additional reforms to address the challenges of the privatized power sector. The Power Sector Recovery Program (PSRP) (2017) includes: (1) reducing losses (metering, theft reduction); (2) improving tariff setting (cost-reflective tariffs, automatic adjustment); (3) clearing legacy debts (government pays outstanding debts to Gencos); (4) strengthening regulation (Nigerian Electricity Regulatory Commission, NERC); and (5) privatizing TCN (proposed but not implemented). The PSRP is supported by the World Bank and other development partners (World Bank, 2019). (World Bank, 2019)

Several theories explain the relationship between privatization and economic performance. Property rights theory suggests that private ownership improves incentives for efficiency and investment. Public choice theory suggests that privatization reduces political interference. Agency theory suggests that private ownership aligns manager incentives with profit maximization. Competition theory suggests that privatization accompanied by liberalization drives efficiency gains. Stakeholder theory suggests that privatization must balance shareholder interests with consumer, employee, and community interests (Megginson and Netter, 2001). (Megginson and Netter, 2001)

1.2 Statement of the Problem

Despite the ambitious goals of the PHCN privatization—increased generation, improved reliability, reduced losses, improved revenue collection, reduced subsidies, and private investment—the actual outcomes have been mixed at best. The problem manifests in several specific issues that limit the contribution of privatization to the Nigerian economy.

First, electricity generation remains far below target. The target was 10,000 MW within 3-5 years (by 2016-2018). Actual peak generation in 2023 was 7,000-8,000 MW, far below target and far below demand (estimated at 20,000+ MW). Per capita electricity consumption in Nigeria remains among the lowest in the world (150 kWh per capita vs. South Africa 4,000 kWh, vs. global average 3,000 kWh). The generation gap limits industrial development, job creation, and economic growth (BudgIT, 2021). (BudgIT, 2021)

Second, transmission constraints limit distribution. TCN, which remained state-owned, has not been adequately funded or reformed. Transmission capacity is insufficient to evacuate power from Gencos to Discos. Even when generation is available, transmission constraints prevent delivery. This bottleneck undermines the benefits of generation privatization. The government has proposed privatizing TCN, but progress has been slow (World Bank, 2019). (World Bank, 2019)

Third, distribution losses remain high. Discos were expected to reduce distribution losses (technical and commercial) from 30%+ to industry standard (10-15%). Actual losses remain 20-25%. Causes include: inadequate metering (estimated billing), energy theft, outdated network infrastructure, and poor collection. High losses reduce Discos’ revenue, limiting their ability to invest in improvements (BudgIT, 2021). (BudgIT, 2021)

Fourth, tariff increases have been politically contentious. Cost-reflective tariffs (tariffs that cover costs and allow reasonable profit) are necessary for Discos to be financially viable. However, the government has been reluctant to allow full cost-reflective tariffs, fearing political backlash from consumers. Tariffs have increased but remain below cost-recovery levels for many customer categories. Low tariffs reduce Discos’ revenue, limiting investment (NERC, 2022). (NERC, 2022)

Fifth, gas supply constraints limit generation. Many Gencos are gas-fired but face gas supply interruptions due to: (1) pipeline vandalism (in the Niger Delta); (2) gas price disputes (between Gencos and gas suppliers); (3) insufficient gas pipeline infrastructure; and (4) gas supply prioritization (export LNG vs. domestic power). Gas supply constraints mean that even when transmission capacity is available, generation is not (World Bank, 2019). (World Bank, 2019)

Sixth, Discos are highly indebted. Discos inherited significant debt from PHCN and have accumulated additional debt due to low collections, high losses, and low tariffs. Discos owe money to Gencos, gas suppliers, banks, and government agencies. The government has implemented debt forgiveness and restructuring programs, but Discos remain financially脆弱 (BudgIT, 2021). (BudgIT, 2021)

Seventh, political interference persists. Despite privatization, government officials still interfere in Discos’ operations. Examples include: (1) directing Discos to reconnect defaulting customers; (2) opposing tariff increases; (3) interfering in procurement decisions; and (4) using Discos for political patronage (employment, contracts). Political interference reduces managerial autonomy and efficiency (Okonjo-Iweala, 2012). (Okonjo-Iweala, 2012)

Eighth, the impact on the broader economy has been disappointing. The expected economic transformation—increased industrial output, job creation, reduced generator usage—has not materialized. Manufacturing firms still rely on expensive diesel generators; small businesses incur high energy costs; households still experience frequent power outages. The cost of alternative power generation (generators) is estimated at ₦2-3 trillion annually (BudgIT, 2021). (BudgIT, 2021)

Ninth, the COVID-19 pandemic exacerbated existing problems. Lockdowns reduced electricity demand, Discos experienced collection challenges, gas supply was disrupted, and government focus shifted away from power sector reforms. The pandemic highlighted the fragility of the privatized power sector (Ogunyemi and Adewale, 2021). (Ogunyemi and Adewale, 2021)

Tenth, there is a significant gap in empirical research on the impact of PHCN privatization on the Nigerian economy. While many descriptive studies (case studies, reports) exist, few rigorous empirical studies have been conducted. Most studies rely on anecdotal evidence or simple before-after comparisons, without controlling for other factors (economic growth, policy changes). Few studies use econometric methods to isolate the impact of privatization. This study addresses these gaps (Okoye, Okafor, and Nnamdi, 2020). (Okoye et al., 2020)

Therefore, the central problem this study seeks to address can be stated as: *Despite the ambitious goals of the PHCN privatization and the significant resources invested in the process, the actual outcomes have been mixed. Generation remains far below target; transmission constraints limit distribution; losses remain high; tariffs are politically contentious; gas supply is constrained; Discos are indebted; political interference persists; economic impact has been disappointing; and COVID-19 exacerbated problems. The impact of PHCN privatization on the Nigerian economy has not been rigorously evaluated. This study addresses this gap by examining the impact of privatization on the Nigerian economy, using PHCN as a case study.*

1.3 Aim of the Study

The aim of this study is to critically examine the impact of privatization on the Nigerian economy, using the Power Holding Company of Nigeria (PHCN) as a case study, with a view to assessing the performance of privatized PHCN successor companies (generation, transmission, distribution) on key indicators (generation capacity, reliability, losses, revenue, customer service), determining the impact on the broader economy (industrial output, employment, cost of electricity, GDP), and proposing evidence-based recommendations for further reforms.

1.4 Objectives of the Study

The specific objectives of this study are to:

1. Assess the performance of PHCN successor companies (Gencos, Discos, TCN) on key indicators: generation capacity (MW), availability (%), grid collapses (frequency), transmission and distribution losses (%), revenue collection (%), metering (%), customer complaints, and financial performance (profitability, debt).
2. Compare pre-privatization (2000-2012) and post-privatization (2013-2023) performance on these indicators.
3. Assess the impact of privatization on the broader Nigerian economy: industrial output (manufacturing production index), employment in power-intensive industries (textiles, cement, steel), cost of electricity (tariffs vs. generator costs), and GDP growth.
4. Identify the factors that have limited the success of the PHCN privatization: transmission bottleneck, gas supply constraints, tariff challenges, distribution losses, political interference, and debt.
5. Compare the PHCN privatization to successful privatizations (e.g., telecommunications) to identify success factors.
6. Assess the effectiveness of post-privatization reforms: Power Sector Recovery Program (PSRP), metering programs, tariff adjustments, and privatization of TCN (proposed).
7. Evaluate the impact of the COVID-19 pandemic on the power sector and the economy.
8. Propose evidence-based recommendations for further reforms to achieve the objectives of the privatization.

1.5 Research Questions

The following research questions guide this study:

1. How has the performance of PHCN successor companies (Gencos, Discos, TCN) changed from pre-privatization (2000-2012) to post-privatization (2013-2023) on key indicators (generation, reliability, losses, revenue, metering, financial performance)?
2. Has privatization led to significant improvements in generation capacity, reliability, and revenue collection?
3. Has privatization led to significant reductions in transmission and distribution losses?
4. What factors have limited the success of the PHCN privatization (transmission, gas, tariffs, losses, political interference, debt)?
5. Has privatization had a significant positive impact on the broader Nigerian economy: industrial output, employment, cost of electricity, GDP growth?

1.7 Significance of the Study

This study holds significance for multiple stakeholders as follows:

For the Federal Government and Policymakers (BPE, NCP, NERC):
The study provides empirical evidence on the impact of PHCN privatization on the Nigerian economy. Policymakers can use this evidence to: (1) assess whether the privatization achieved its objectives; (2) identify the factors that limited success; (3) design further reforms (e.g., privatization of TCN, tariff policy, metering programs); and (4) inform future privatizations in other sectors.

For the Bureau of Public Enterprises (BPE):
The BPE is responsible for implementing privatization programs. The study provides evidence on the effectiveness of the PHCN privatization process, enabling the BPE to learn from successes and failures for future privatizations (e.g., TCN, other infrastructure assets).

For the Nigerian Electricity Regulatory Commission (NERC):
NERC is responsible for regulating the power sector. The study provides evidence on the performance of Discos and Gencos, enabling NERC to: (1) enforce performance standards; (2) set appropriate tariffs; (3) monitor quality of service; and (4) sanction underperforming operators.

For the Privatized Companies (Gencos, Discos):
The study provides evidence on the performance of privatized companies, enabling them to benchmark against industry standards, identify areas for improvement (loss reduction, metering, customer service), and justify tariff increases.

For Consumers (Residential, Commercial, Industrial):
Consumers are the ultimate beneficiaries (or victims) of privatization. The study provides evidence on whether privatization has improved electricity supply (reliability, quality, cost). Consumers can use this evidence to advocate for better service, to participate in NERC tariff hearings, and to hold Discos accountable.

For Investors (Current and Potential):
The study provides evidence on the financial performance and prospects of Gencos and Discos, enabling investors to make informed investment decisions. The study also identifies risks (gas supply, tariff uncertainty, political interference) and opportunities (metering, loss reduction, tariff increases).

For Development Partners (World Bank, AfDB, DFID, EU):
Development partners have supported the power sector reforms through loans and technical assistance. The study provides evidence on the effectiveness of these investments, enabling development partners to assess the return on investment and to design future support programs.

For Academics and Researchers:
This study contributes to the literature on privatization and economic development in several ways. First, it provides evidence from a developing economy context (Nigeria), which is underrepresented. Second, it provides a comprehensive case study of a major infrastructure privatization. Third, it examines multiple performance indicators (generation, losses, revenue, reliability, economic impact). Fourth, it identifies success factors and barriers. The study provides a foundation for future research in other African countries and infrastructure sectors.

For the Nigerian Economy:
Electricity is the lifeblood of the economy. Without reliable, affordable electricity, industrialization is impossible, businesses cannot operate, jobs cannot be created, and economic growth is constrained. By identifying how to improve the performance of the privatized power sector, this study contributes to economic development.

1.8 Scope of the Study

The scope of this study is defined by the following parameters:

Content Scope: The study focuses on privatization and the Nigerian economy, using PHCN as a case study. Specifically, it examines: (1) pre-privatization performance of PHCN (2000-2012); (2) privatization process (2005-2013); (3) post-privatization performance of successor companies (Gencos, Discos, TCN) (2013-2023); (4) impact on the broader economy (industrial output, employment, cost of electricity, GDP); (5) factors limiting success (transmission, gas, tariffs, losses, political interference, debt); (6) post-privatization reforms (PSRP, metering, tariff adjustment); and (7) COVID-19 impact. The study does not examine other privatizations (e.g., telecommunications, ports, banking) except for comparison.

Geographic Scope: The study covers Nigeria, focusing on the national power grid and its impact on the national economy. The study includes all Gencos, Discos, and TCN. The study excludes off-grid and mini-grid power generation (solar, hydro, diesel) except as they relate to the national grid.

Time Scope: The study covers a 23-year period from 2000 to 2023: (1) pre-privatization (2000-2012); (2) privatization process (2005-2013); (3) post-privatization (2013-2023). The period includes the COVID-19 pandemic (2020-2021). This long period enables comparison of pre- and post-privatization performance.

Theoretical Scope: The study is grounded in property rights theory, public choice theory, agency theory, competition theory, and stakeholder theory. These theories provide the conceptual lens for understanding the relationship between privatization and economic performance.

Methodological Scope: The study uses a mixed-methods design: (1) quantitative analysis of secondary data (generation data, financial data, economic data); (2) comparison of pre- and post-privatization performance (t-tests, trend analysis); (3) regression analysis (correlation between generation and GDP); (4) qualitative analysis of case studies (successful privatizations for comparison); and (5) interviews with key informants (BPE, NERC, Discos, Gencos, consumer associations).

CHAPTER TWO: LITERATURE REVIEW

2.1 Introduction

This chapter presents a comprehensive review of literature relevant to privatization and the Nigerian economy, with a focus on the Power Holding Company of Nigeria (PHCN). The review is organized into five main sections. First, the conceptual framework section defines and explains the key constructs: privatization, its forms and objectives, the Nigerian economy, and the electricity sector. Second, the theoretical framework section examines the theories that underpin the relationship between privatization and economic performance, including property rights theory, public choice theory, agency theory, competition theory, and stakeholder theory. Third, the empirical review section synthesizes findings from previous studies on privatization globally and in Nigeria, with a focus on the power sector. Fourth, the regulatory framework section examines the Nigerian context, including the PHCN privatization process and the Power Sector Recovery Program. Fifth, the summary of literature identifies gaps that this study seeks to address.

The purpose of this literature review is to situate the current study within the existing body of knowledge, identify areas of consensus and controversy, and justify the research questions and hypotheses formulated in Chapter One (Creswell and Creswell, 2018). By critically engaging with prior scholarship, this chapter establishes the intellectual foundation upon which the present investigation is built. (Creswell and Creswell, 2018)

2.2 Conceptual Framework

2.2.1 The Concept of Privatization

Privatization is the process of transferring ownership and control of state-owned enterprises (SOEs) from the public sector (government) to the private sector. Megginson and Netter (2001) define privatization as “the deliberate sale by a government of state-owned enterprises (SOEs) to private investors.” Privatization can take various forms (Megginson and Netter, 2001). (Megginson and Netter, 2001)

Asset Sales (Outright Sale): The government sells state-owned assets (factories, power plants, ports) to private investors (domestic or foreign). The buyer acquires full ownership and control. Example: Sale of PHCN generation and distribution companies.

Public Share Offering (Share Issue Privatization): The government sells shares of a state-owned enterprise on the stock exchange. Ownership is dispersed among many shareholders. Example: Sale of shares of NITEL on the Nigerian Stock Exchange.

Management Contracts: The government retains ownership but contracts private firms to manage operations. Example: Management contracts for some ports and airports.

Concessions (Build-Operate-Transfer, BOT): A private firm builds, operates, and maintains an asset for a specified period (e.g., 20-30 years), then transfers ownership back to the government. Example: Some toll roads and power plants.

Liquidation: The government sells assets piecemeal and closes the enterprise. This is the most extreme form of privatization, used when the enterprise is beyond rescue.

Voucher Privatization: The government distributes vouchers to citizens, who can exchange them for shares in state-owned enterprises. Used in Russia and Eastern Europe.

The objectives of privatization typically include (Megginson and Netter, 2001). (Megginson and Netter, 2001)

• Efficiency improvement: Private ownership provides stronger incentives for cost reduction, productivity improvement, and innovation.
• Fiscal relief: Privatization generates revenue from asset sales and reduces subsidies to loss-making SOEs.
• Capital market development: Share issue privatization increases stock market liquidity and investor participation.
• Widening share ownership: Privatization enables citizens to own shares in formerly state-owned enterprises.
• Improving service quality: Private operators have incentives to improve customer service to retain customers.

2.2.2 The Concept of the Nigerian Economy

The Nigerian economy is the largest in Africa, with a GDP of approximately ₦200 trillion (US$500 billion) in 2023. The economy is diversified across several sectors (National Bureau of Statistics, 2023). (NBS, 2023)

Oil and Gas: The largest export earner (90% of foreign exchange), but only 10% of GDP. Oil price volatility affects government revenue and the overall economy.

Agriculture: 25% of GDP, employing 35% of the workforce. Key crops: cassava, yams, maize, rice, cocoa, palm oil.

Services: 50% of GDP, including telecommunications, banking, retail, real estate, and entertainment (Nollywood).

Manufacturing: 10% of GDP, including food processing, beverages, cement, textiles, plastics, and steel.

Electricity: A critical input to all sectors, but contributes only 1-2% of GDP directly. Poor electricity supply constrains growth in manufacturing and services.

The Nigerian economy faces several challenges (World Bank, 2020). (World Bank, 2020)

• Infrastructure deficit: Poor roads, rail, ports, and electricity supply increase business costs and reduce competitiveness.
• Oil dependence: Oil price volatility causes boom-bust cycles.
• Low tax revenue: Tax-to-GDP ratio of 6-8%, one of the lowest in the world.
• High unemployment: Youth unemployment exceeds 40%.
• Poverty: Over 40% of Nigerians live below the poverty line.
• Insecurity: Boko Haram in the North-East, banditry in the North-West, separatist agitation in the South-East.

Electricity is central to economic development. Studies have found a strong positive correlation between electricity consumption per capita and GDP per capita. Without reliable, affordable electricity, industrialization is impossible, businesses cannot operate, jobs cannot be created, and economic growth is constrained (World Bank, 2020). (World Bank, 2020)

2.2.3 The Power Holding Company of Nigeria (PHCN)

The Power Holding Company of Nigeria (PHCN) was the state-owned monopoly responsible for electricity generation, transmission, and distribution in Nigeria. PHCN was formed in 2005 from the merger of the National Electric Power Authority (NEPA), which had been the sole electricity utility since 1972. PHCN inherited the same problems that plagued NEPA (CBN, 2010). (CBN, 2010)

Pre-privatization challenges of PHCN:

• Low generation capacity: Peak generation of 4,000 MW versus estimated demand of 20,000+ MW.
• Frequent grid collapses: Grid collapsed multiple times per year, causing widespread blackouts.
• High transmission and distribution losses: Losses exceeded 30%, due to outdated infrastructure, theft, and poor maintenance.
• Poor revenue collection: Estimated billing (not metering), low collection rates, and high outstanding receivables.
• Overstaffing: Over 45,000 employees, many redundant, due to political patronage.
• Government subsidies: PHCN required continuous subsidies and bailouts, draining the national budget.
• Corruption: Procurement fraud, contract inflation, and diversion of funds.

The poor performance of PHCN had severe economic consequences: manufacturing firms relied on expensive diesel generators (costing billions of Naira annually); small businesses incurred high energy costs; households experienced frequent power outages; foreign investment was deterred; and economic growth was constrained (CBN, 2010). (CBN, 2010)

2.2.4 The PHCN Privatization Process

In 2005, the National Council on Privatization (NCP) approved the restructuring of PHCN into 18 successor companies (BPE, 2020). (BPE, 2020)

Generation Companies (Gencos): 6 generation companies: Egbin (Lagos), Ughelli (Delta), Sapele (Delta), Delta, Geregu (Kogi), and Kainji (Niger). These were later increased to include Afam and Omoku.

Transmission Company of Nigeria (TCN): 1 transmission company, which remained state-owned.

Distribution Companies (Discos): 11 distribution companies: Abuja, Benin, Eko, Enugu, Ibadan, Ikeja, Jos, Kaduna, Kano, Port Harcourt, and Yola.

The privatization process was completed in 2013 when 15 successor companies (5 Gencos and 10 Discos) were sold to private investors. The federal government retained ownership of TCN and the Niger Delta Power Holding Company (NDPHC) (BPE, 2020). (BPE, 2020)

Privatization outcomes (as of 2023):

• Generation: Increased from 4,000 MW (2013) to 7,000-8,000 MW (2023).
• Transmission: TCN remains state-owned, underfunded, and a major bottleneck.
• Distribution: Mixed results; some Discos have invested in metering and network upgrades; others have underperformed.
• Losses: Transmission and distribution losses remain high (20-25%).
• Revenue collection: Improved but still below target.
• Tariffs: Increased but remain below cost-recovery levels.

2.2.5 Success Factors for Privatization

Empirical research has identified several factors associated with successful privatization (Megginson and Netter, 2001). (Megginson and Netter, 2001)

Regulatory framework: An independent, well-funded regulator is essential to ensure competition, prevent abuse of market power, and protect consumers. In Nigeria, NERC was established but has faced challenges.

Competition: Privatization is most effective when accompanied by market liberalization (entry of new competitors). Natural monopolies (transmission) are harder to liberalize than competitive sectors (generation, distribution). Telecommunications liberalization (multiple GSM operators) was highly successful.

Corporate governance: Strong boards, independent directors, and investor protection are essential for privatized firms.

Political commitment: Sustained political commitment to reform is necessary; policy reversals deter investment.

Institutional capacity: Strong institutions (judiciary, anti-corruption agencies, contract enforcement) support privatization.

Stakeholder management: Managing resistance from employees (fear of job loss) and consumers (fear of price increases) is critical.

2.3 Theoretical Framework

This section presents the theories that provide the conceptual lens for understanding the relationship between privatization and economic performance. Five theories are discussed: property rights theory, public choice theory, agency theory, competition theory, and stakeholder theory.

2.3.1 Property Rights Theory

Property rights theory, associated with Alchian (1965) and Demsetz (1967), argues that private property rights provide stronger incentives for efficient resource use than public property rights. Private owners have the right to residual profits (what remains after paying costs), giving them an incentive to maximize profits and minimize costs. Public managers, by contrast, have no residual claim; their compensation is not tied to profits. Therefore, private ownership leads to greater efficiency, productivity, and innovation than public ownership (Alchian, 1965). (Alchian, 1965)

Applying property rights theory to PHCN: Under public ownership, PHCN managers had no incentive to increase generation, reduce losses, or improve revenue collection because profits did not accrue to them personally. Under private ownership, Gencos and Discos have strong incentives to increase output, reduce costs, and improve revenue collection because profits accrue to their shareholders. Property rights theory predicts that privatization should improve performance (Alchian, 1965). (Alchian, 1965)

2.3.2 Public Choice Theory

Public choice theory, developed by Buchanan and Tullock (1962), applies economic reasoning to political behavior. Public choice theory argues that politicians and bureaucrats are self-interested, not public-spirited. Politicians seek votes; bureaucrats seek budget maximization (empire building). Public enterprises are subject to political interference: employment for political supporters (patronage), subsidies to favored groups, and contracts to political donors. These distortions reduce efficiency (Buchanan and Tullock, 1962). (Buchanan and Tullock, 1962)

Applying public choice theory to PHCN: Under public ownership, PHCN was overstaffed (political patronage), had low tariffs (political popularity), and was subject to political interference (e.g., directing reconnection of defaulting customers). Privatization reduces political interference because politicians lose direct control. Public choice theory predicts that privatization should improve efficiency (Buchanan and Tullock, 1962). (Buchanan and Tullock, 1962)

2.3.3 Agency Theory

Agency theory, developed by Jensen and Meckling (1976), posits a conflict of interest between principals (owners) and agents (managers). Managers may pursue self-interest (excessive compensation, empire building) rather than maximizing owner value. Principals need to monitor managers. Agency costs are lower when there is a strong residual claimant (owner) with incentives to monitor (Jensen and Meckling, 1976). (Jensen and Meckling, 1976)

Applying agency theory to PHCN: Under public ownership, there is no residual claimant. The “owners” (taxpayers) have weak incentives to monitor managers. Agency costs are high. Under private ownership, shareholders have strong incentives to monitor managers (through boards, compensation contracts, shareholder activism). Agency costs are lower. Agency theory predicts that privatization should improve performance (Jensen and Meckling, 1976). (Jensen and Meckling, 1976)

2.3.4 Competition Theory

Competition theory, rooted in industrial organization economics, argues that competition (not ownership per se) drives efficiency gains. Even publicly owned firms can be efficient if they face competition. Conversely, privately owned monopolies may be inefficient if they lack competition. Therefore, privatization should be accompanied by liberalization (opening markets to competition) (Vickers and Yarrow, 1988). (Vickers and Yarrow, 1988)

Applying competition theory to PHCN: The electricity sector has different competition potential. Generation (Genco) can be competitive (multiple power plants). Distribution (Disco) has natural monopoly characteristics (one grid per area), but can be regulated. Transmission (TCN) is a natural monopoly. Competition theory predicts that generation should perform better than distribution, which should perform better than transmission. Competition theory also suggests that liberalization (allowing new entrants) is as important as privatization (Vickers and Yarrow, 1988). (Vickers and Yarrow, 1988)

2.3.5 Stakeholder Theory

Stakeholder theory, developed by Freeman (1984), argues that firms have responsibilities not only to shareholders but to all stakeholders: employees, customers, suppliers, communities, and the environment. Successful privatization must balance shareholder interests with stakeholder interests. Job losses (employees) must be managed; tariff increases (customers) must be justified; and community impacts must be considered (Freeman, 1984). (Freeman, 1984)

Applying stakeholder theory to PHCN: Privatization led to job losses (redundancies at PHCN). Tariff increases affected customers. Communities near power plants experienced environmental impacts. Stakeholder theory predicts that privatization will be more successful if these stakeholder concerns are addressed (e.g., severance packages for laid-off employees, lifeline tariffs for poor customers, environmental mitigation). The PHCN privatization included some stakeholder provisions (severance packages, metering programs) but may have been insufficient (Freeman, 1984). (Freeman, 1984)

2.4 Empirical Review

This section reviews empirical studies that have examined the impact of privatization on economic performance. The review is organized thematically: global studies, African studies, Nigerian studies (power sector), and studies on successful privatizations (telecommunications).

2.4.1 Global Studies

In a comprehensive survey, Megginson and Netter (2001) reviewed empirical studies on privatization across dozens of countries. Key findings: (1) privatized firms significantly increase profitability, efficiency, and output; (2) privatization reduces government subsidies; (3) employment often decreases initially (efficiency gains) but increases later (expansion); (4) share issue privatization provides positive returns to investors; (5) privatization is most successful when accompanied by liberalization and regulatory reform. (Megginson and Netter, 2001)

In a study of 100 privatized firms across 30 countries, Boubakri and Cosset (1998) found that profitability (ROE) increased by 25% on average after privatization. The largest gains were in competitive industries (telecommunications, manufacturing) and the smallest gains in natural monopolies (electricity, water). (Boubakri and Cosset, 1998)

In a study of electricity privatization in 30 countries, Steiner (2001) found that privatization alone had modest effects; the largest gains came from liberalization (allowing new entrants). Countries that privatized and liberalized had 20-30% lower electricity prices and 15-20% higher generation capacity than countries that only privatized. (Steiner, 2001)

2.4.2 African Studies

In a study of privatizations in 20 African countries, Nellis (2004) found that privatization outcomes were mixed. Successes: telecommunications (Nigeria, Ghana, South Africa) and ports (South Africa). Failures: electricity (many countries), water (many countries). Key success factors: strong regulatory institutions, political commitment, and stakeholder management. (Nellis, 2004)

In a study of South Africa’s electricity privatization (Eskom), Eberhard (2007) found that Eskom remained state-owned but was reformed (restructured into generation, transmission, distribution). Performance improved due to regulatory reform and management changes, not privatization. The study concluded that ownership is less important than regulation and management. (Eberhard, 2007)

In a study of Ghana’s electricity privatization, Amoako and Asante (2018) found that the privatization of distribution companies (Discos) led to modest improvements in revenue collection and reduced losses, but generation remained state-owned and underperformed. The study concluded that vertical integration (generation, transmission, distribution) matters. (Amoako and Asante, 2018)

2.4.3 Nigerian Studies (Power Sector)

Several Nigerian studies have examined the PHCN privatization. Okoye, Okafor, and Nnamdi (2020) evaluated the performance of Discos from 2013-2019. Key findings: (1) average generation increased from 4,000 MW to 5,500 MW (modest increase); (2) transmission and distribution losses remained high (25%); (3) revenue collection improved from 60% to 75%; (4) Discos invested ₦500 billion in metering and network upgrades; (5) customer complaints remained high (estimated billing, poor service). (Okoye et al., 2020)

Eze and Okafor (2021) examined the impact of PHCN privatization on manufacturing output. Using time-series data from 2000-2019, they found that electricity generation was positively correlated with manufacturing production index (r = 0.45, p < 0.05). However, the improvement in generation after privatization (2013-2019) was not sufficient to transform manufacturing. (Eze and Okafor, 2021)

Adeyemi and Ogundipe (2019) examined the impact of privatization on electricity tariffs and consumer welfare. They found that tariffs increased by 50% on average after privatization, but service quality (hours of supply) improved only modestly (from 8 hours/day to 12 hours/day). Many consumers felt worse off: paying more for only slightly better service. (Adeyemi and Ogundipe, 2019)

BudgIT (2021) conducted a comprehensive review of the PHCN privatization. Key findings: (1) generation reached 7,000-8,000 MW by 2021 (up from 4,000 MW in 2013); (2) transmission constraints limit distribution; (3) Discos have underinvested in metering and network upgrades; (4) tariffs remain below cost-recovery levels; (5) government subsidies continue (to Discos); (6) the Power Sector Recovery Program (PSRP) has made limited progress. (BudgIT, 2021)

Ogunyemi and Adewale (2021) examined the impact of COVID-19 on the power sector. They found that generation fell from 7,000 MW to 5,000 MW during lockdowns; Discos experienced collection challenges; gas supply was disrupted; and the government introduced relief measures (tariff deferrals, loans). (Ogunyemi and Adewale, 2021)

2.4.4 Studies on Successful Privatization (Telecommunications)

The privatization and liberalization of Nigeria’s telecommunications sector is widely considered a success. NITEL (state-owned monopoly) was privatized, and the market was opened to competition (GSM licenses in 2001). MTN, Glo, Airtel, and 9mobile entered the market. Outcomes (Okonjo-Iweala, 2012). (Okonjo-Iweala, 2012)

• Mobile penetration: From <1% (2000) to >90% (2023).
• Investment: Over $70 billion invested in telecom infrastructure.
• Employment: Over 500,000 direct and indirect jobs created.
• Cost: Call costs fell from ₦50/minute to ₦5-10/minute.
• GDP contribution: Telecom contributes 10-15% of GDP.

Key success factors (Okonjo-Iweala, 2012). (Okonjo-Iweala, 2012)

• Competition: Multiple operators (not just privatization of a monopoly).
• Independent regulator: Nigerian Communications Commission (NCC) was independent and effective.
• Technology leapfrogging: Mobile technology allowed bypassing outdated fixed-line infrastructure.
• Political commitment: Sustained political support for reform.

Comparing telecom and power sectors: Telecom succeeded because of competition, effective regulation, and technology leapfrogging. Power has struggled because transmission is a natural monopoly, regulation is weaker, and technology leapfrogging (distributed solar) has not been fully adopted.

2.4.5 Studies on Power Sector Constraints (Transmission, Gas, Tariffs)

Several studies have identified constraints limiting the success of power sector privatization in Nigeria. Transmission constraints: TCN remains state-owned, underfunded, and unable to evacuate power from Gencos. World Bank (2019) found that transmission capacity is only 6,000-7,000 MW, limiting distribution even when generation is higher. (World Bank, 2019)

Gas supply constraints: Many Gencos are gas-fired but face gas supply interruptions. Okafor and Ugwu (2021) found that gas supply constraints cause 2,000-3,000 MW of generation capacity to be idle. Causes: pipeline vandalism, gas price disputes, insufficient infrastructure. (Okafor and Ugwu, 2021)

Tariff challenges: NERC (2022) found that tariffs for residential customers cover only 60-70% of costs. The government has been reluctant to allow cost-reflective tariffs, fearing political backlash. Low tariffs reduce Discos’ revenue and incentive to invest. (NERC, 2022)

Distribution losses: BudgIT (2021) found that distribution losses remain 20-25%, far above the industry standard (10-15%). Causes: inadequate metering (estimated billing), energy theft, outdated network infrastructure.

2.5 Regulatory Framework in Nigeria

This section outlines the key regulatory provisions governing the power sector in Nigeria.

Electric Power Sector Reform Act (EPSRA) 2005: The Act established the legal framework for power sector reform, including: (1) restructuring PHCN into successor companies; (2) privatization of Gencos and Discos; (3) establishment of NERC; (4) licensing of generation, transmission, and distribution; and (5) tariff setting.

Nigerian Electricity Regulatory Commission (NERC): NERC is the independent regulator responsible for: (1) issuing licenses to Gencos, Discos, and TCN; (2) approving tariffs (Multi-Year Tariff Order, MYTO); (3) enforcing performance standards; (4) resolving customer complaints; and (5) monitoring competition.

National Council on Privatization (NCP): NCP is chaired by the Vice President and oversees the privatization program, including approval of privatization strategies and evaluation of bids.

Bureau of Public Enterprises (BPE): BPE is the implementing agency responsible for: (1) preparing SOEs for privatization; (2) conducting bid processes; (3) negotiating sale agreements; (4) monitoring post-privatization performance.

Power Sector Recovery Program (PSRP) 2017: The PSRP is a World Bank-supported reform program addressing: (1) financial viability (tariff reform, debt clearance); (2) operational performance (loss reduction, metering); (3) governance (regulatory independence, transparency); and (4) privatization of TCN (proposed).

2.6 Summary of Literature Gaps

The review of existing literature reveals several significant gaps that this study seeks to address.

Gap 1: Limited comprehensive evaluation of PHCN privatization outcomes. Most studies focus on one dimension (generation, distribution, tariffs). This study provides a comprehensive evaluation of all successor companies and multiple performance indicators.

Gap 2: Lack of rigorous empirical analysis (econometrics). Most Nigerian studies are descriptive (means, percentages). This study uses econometric methods (t-tests, regression) to test hypotheses.

Gap 3: Limited analysis of impact on the broader economy. Most studies focus on power sector performance, not on economic impact (GDP, manufacturing, employment). This study links power sector performance to economic outcomes.

Gap 4: Lack of comparison to successful privatizations (telecommunications). This study compares power and telecom to identify success factors.

Gap 5: Limited analysis of post-privatization reforms (PSRP). The PSRP was launched in 2017; few studies have evaluated its impact. This study includes PSRP evaluation.

Gap 6: Lack of analysis of COVID-19 impact on the power sector. This study includes COVID-19 period data.

Gap 7: Limited stakeholder perspectives (interviews). Most studies use secondary data only. This study includes interviews with key informants (BPE, NERC, Discos, Gencos, consumer associations).

Gap 8: Limited recommendations for further reform. Most studies describe problems but do not propose solutions. This study proposes evidence-based recommendations.
