Nigeria’s Electricity Act 2023: What Changed and What It Means for the Power Sector

Nigeria’s electricity sector is undergoing one of its most significant structural changes in decades. The Electricity Act 2023 introduced a new framework for how electricity markets can be developed, regulated and operated across the country, moving Nigeria away from a largely centralised electricity model towards a more decentralised and competitive system.

The reform comes against the backdrop of longstanding challenges in Nigeria’s power sector. Despite significant generation capacity, actual electricity supply remains far below the country’s potential demand. Generation capacity is underutilised, transmission and distribution losses remain high, and millions of Nigerians continue to operate without reliable access to grid electricity. These challenges have made it increasingly clear that expanding electricity access requires more than simply increasing generation. It requires a fundamental rethink of how the market is structured.

The Electricity Act 2023 is part of that structural shift.

Before the Act, Nigeria’s electricity sector was largely organised around a single national electricity market under federal oversight. The federal government, through existing regulatory and market structures, maintained significant control over the sector, while states had limited authority to independently develop and regulate electricity markets within their territories.

The Electricity Act changes this framework by allowing states to establish and regulate their own electricity markets, subject to the conditions set out under the law. This creates the possibility of multiple electricity markets operating alongside the national market, with states able to develop systems that respond more directly to their specific energy needs and economic priorities.

This is a significant change for the sector. Nigeria’s states have different population sizes, industrial bases, natural resources, electricity demand profiles and infrastructure needs. A single national approach may therefore not always be sufficient to address the particular challenges and opportunities in each market.

Under the new framework, states can establish state electricity regulatory commissions to oversee intrastate electricity activities. The Nigerian Electricity Regulatory Commission continues to regulate interstate and international electricity markets, while states that meet the relevant conditions can assume greater control over electricity activities within their territories. The result is a dual regulatory framework that introduces greater flexibility into the market while also creating new questions around coordination, licensing, market boundaries and regulatory oversight.

The Electricity Act 2023 also opens the door to broader private sector participation across the electricity value chain. Private players can participate in generation, transmission, distribution, supply and electricity trading, creating opportunities for new business models and investment structures.

The Act also reduces barriers to entry in certain areas of electricity generation. Generation projects below 1MW do not require a licence under the new framework, subject to the applicable provisions of the law. This can support the growth of smaller-scale generation projects, including embedded generation and distributed energy solutions.

For a country where millions of people remain without reliable grid access, decentralised energy systems can play an important role. Solar, wind, hydro, biomass and hybrid generation models are increasingly relevant to the future of Nigeria’s energy system, particularly where extending traditional grid infrastructure may be difficult or uneconomical.

The new framework formally supports the development of renewable energy and other alternative power solutions through mechanisms such as feed-in tariffs, fiscal incentives and new market structures. This creates opportunities for investors and project developers, although the commercial viability of individual projects will still depend on factors including tariffs, offtake arrangements, financing, regulation and the reliability of the surrounding infrastructure.

Another important structural change under the electricity reforms is the separation of system and market operations from the ownership and management of transmission infrastructure.

Previously, the Transmission Company of Nigeria performed both functions. Under the new structure, the Nigeria Independent System Operator is responsible for functions such as grid coordination, dispatch, scheduling and system and market operations, while the Transmission Service Provider is responsible for the physical transmission infrastructure.

The distinction is important because the body responsible for operating and coordinating the electricity system is separated from the entity responsible for owning and maintaining the physical transmission assets. For investors and market participants, this can create greater clarity around roles and responsibilities and support a more transparent and competitive electricity market.

Lagos provides an important example of what the development of a state-level electricity market could look like in practice. The state has established the Lagos State Electricity Regulatory Commission, which is responsible for regulating electricity activities within the state’s market. The Lagos Independent System Operator is also intended to manage system coordination and dispatch within the state, while existing distribution companies are being restructured into state-aligned subsidiaries as part of the transition towards a more decentralised market structure.

The development of these institutions demonstrates that the Electricity Act is not simply a change in legislation. It creates the basis for new market institutions, new regulatory responsibilities and new relationships between state governments, investors, electricity companies and consumers. Other states are likely to observe these developments closely as they consider whether and how to establish their own electricity markets.

The Act creates new opportunities for investment in Nigeria’s power sector, but the existence of a legal framework alone will not be enough to attract capital. Investors will need clarity on the regulatory environment, licensing requirements, tariffs, offtake arrangements and the responsibilities of different market participants. State governments seeking to attract private investment will also need to develop the institutional and commercial structures required to support viable electricity projects.

For example, a state seeking to develop a large independent power project may need to consider whether the appropriate regulatory institutions are in place, how the project will connect to the electricity market, who will purchase the power and how payment and offtake risks will be managed. These questions have direct implications for project feasibility and financing. The commercial structure of an electricity project must be supported by a clear regulatory framework and a credible source of revenue.

As the electricity market becomes more decentralised, understanding the relationship between regulation, infrastructure, investment and commercial viability will be essential. States will need to consider how electricity can support their broader economic development objectives, while investors and project developers will need to navigate an increasingly complex market structure.

The Electricity Act 2023 represents a fundamental change to the architecture of Nigeria’s electricity market. It introduces the possibility of multiple state-level electricity markets, expands opportunities for private sector participation, creates a dual regulatory structure and separates system operations from transmission asset ownership.

However, implementation will be critical. The success of the reforms will depend on the ability of institutions to develop the necessary regulatory frameworks, the willingness of investors to commit capital, the ability of states to build effective market institutions and the capacity of market participants to operate within the new structure.

The transition will not happen uniformly across the country. Some states may move more quickly than others, depending on their institutional capacity, electricity demand, infrastructure and ability to attract investment.

What is clear is that Nigeria’s electricity market is moving towards a more decentralised model. The Electricity Act 2023 provides the legal foundation for that transition, but the real impact will be determined by how the opportunities created by the law are translated into functioning markets and viable electricity projects.

For businesses, investors, project developers and state governments, understanding the new electricity market structure will be increasingly important. The next phase of Nigeria’s power sector will not be shaped by regulation alone but by the interaction between policy, capital, infrastructure and execution.
