South Africa neither has an accepted definition for minigrids or microgrids, nor an established regulatory framework including licensing and tariff regime, as well as technical standards for service quality related to microgrid assets. While the INEP defines electrification targets, neither the INEP nor SAREM contain specific targets or exact plans for microgrid deployment, which could provide some investment certainty. Data on unelectrified communities, their socio-economic profile and geospatial data to inform the selection of promising sites for microgrid deployment is currently not easily publicly accessible and not available through a centralised platform.
Major regulatory transformations in South Africa’s electricity sector have, however, improved the enabling environment for microgrid deployment in recent years. The country is in a transition process from an integrated monopoly, where its state-owned and vertically integrated utility Eskom acted at the single buyer, towards full market liberalisation which enables distributed electricity generation.
Existing regulations were mostly designed for large-scale centralised power plants, lacking clear rules for grid access by microgrids and creating lengthy licensing approval processes (Granville Energy, 2025[6]).Neither the Electricity Regulation Act of 2003, nor the Licensing Exemption and Registration Notice No. 402 of January 2023 currently define microgrids as a licensable activity under South African law. Clarifying NERSA’s mandate for issuing microgrid licenses and advancing the current discussions on the design of a suitable microgrid regulatory framework will be important steps for their deployment, particularly in light of the need to mobilise private finance and investment. Recent regulatory changes, however, had positive implications for microgrid deployment, and particularly for grid-tied solutions.
An amendment to Schedule 2 of the Electricity Regulation Act (ERA) relaxed the licensing threshold for generators of distributed energy resources (DERs) to 100 MW in 2021. This significantly reduced bureaucratic hurdles and accelerated project implementation timelines, unlocking a pipeline of more than 80 projects (Granville Energy, 2025[6]). Previously, DER projects with a capacity above 1MW had to obtain a license from the National Energy Regulator of South Africa (NERSA), with a 120-day decision timeframe.
The 2023 adjustment removed the licensing requirement for generation facilities of all capacities, provided that they are connected to the transmission or distribution grid (i.e. embedded). This further accelerated implementation timeframes for embedded generation projects and aimed to promote private investment (Granville Energy, 2025[6]). Small-scale embedded generation (SSEG) systems under 100 kW still require registration with the utility (either Eskom or the municipality), which can be a cumbersome process. Grid-tied systems between 100kW and 100 MW nonetheless require registration with NERSA (Eskom, 2026[18]). While a Certificate of Compliance confirms that an SSEG installation such as a rooftop solar system meets electrical safety standards, registration ensures that such systems are connected safely and integrated responsibly into the electricity network. All registration and connection fees including a free smart meter29F3 are waived until 30 September 2026 for Eskom customer solar systems up to 50kVa (Eskom, 2026[18]), reducing overall system costs. However, many municipalities in Mpumalanga face significant capacity constraints and do not yet enable SSEG installations (Chapter 2). Isolated microgrids are not covered by these legal changes.
As a unique characteristic of South Africa’s electricity sector, municipalities have the authority to distribute electricity in their area of jurisdiction,30F4 subject to legislation and regulation by the national and provincial governments. The Municipal Systems Act (Act No. 32 of 2000) establishes municipalities as service authorities with responsibility for developing policies, drafting by-laws, setting tariffs and regulating the provision of services through by-laws and other mechanisms.
Electricity distribution is a major source of revenue for municipalities, as the Municipal Fiscal Powers and Functions Act allows municipalities to levy a surcharge on electricity tariffs, even if it is provided by Eskom (Statistics South Africa, 2024[2]). Third-party wheeling of energy is currently subject to the buyer being connected to a medium-voltage or higher-voltage network and being on a time-of-use tariff, and the generator being licensed/registered to generate and supply the network with electricity. While the regulatory removal of the licensing requirements for embedded generation per se would not exclude microgrids from participating in wheeling, it is currently not allowed for low-voltage connections of less than 1 kV – which are typical for many small rural or community microgrids (Eskom, 2026[19]).
The Electricity Regulation Amendment Act of 202431F5 (ERA) establishes a liberalised and diversified market by unbundling Eskom and creating the state-owned National Transmission System Company of South Africa (NTCSA) as independent system operator to ensure fair grid access. The act empowers private actors to participate freely and directly in electricity market transactions, and end-users to choose their electricity provider based on service quality, price and reliability, thereby fostering competition. These reforms eased previously existing barriers to market entry and grid access for microgrids and strengthened the regulatory framework for private investment (Granville Energy, 2025[6]). Microgrids are neither covered in the ERA or its amendments, nor in the licensing exemptions or registration notices issued by the then DMRE. This means that an enabling legislation, issued by the DEE, would be needed to empower NERSA to regulate the emerging microgrid industry in South Africa.
In December 2024, NERSA approved a net-billing framework, under which “prosumers”, meaning active energy consumers that both consume and produce electricity, are billed at the standard retail tariff for all electricity imported from the grid, while receiving a credit for electricity exported to the grid at a typically lower “export tariff”. Subject to NERSA’s approval and overarching principles of fairness and cost-reflectivity, municipal distributors can design specific tariffs and technical requirements (Lopile Tech, 2025[20]), which introduces implementation complexities and uncertainty for microgrid developers. While net-billing incentivises private investment in SSEG, it also incentivises the maximisation of on-site self-consumption, for instance through optimal battery storage systems. Revenues from electricity sales make up 30% or more of total municipal revenues in many cases (Lopile Tech, 2025[20]), so the rise of distributed renewable energy generation constitutes a thread to this financial utility model. The net-billing framework ensures that the fixed network and service charges are paid by all customers regardless of their consumption levels.
While recent regulatory reforms have improved the investment environment for renewable energy generation and microgrids, the absence of dedicated microgrid regulations continues to pose significant challenges. These include gaps in tariff design, grid encroachment frameworks, as well as uncertainty around complex and long licensing and permitting processes. The need for more coordinated planning and streamlined procurement processes was highlighted, particularly with regard to municipal electrification programmes (Department of Electricity and Energy, 2025[1]). A draft regulatory microgrid framework, tariff guidelines and contractual templates are currently being drafted to accelerate PPP procurement for microgrid projects. Updated provincial electrification master plans with geospatial data shall guide aligned planning processes and reduce uncertainty for investors (OECD, 2026[21]).
Major international initiatives and programmes supporting the deployment of mini-grids or microgrids, such as the AfDB and WB-led Mission 300 initiative or the Africa Mini-grids Programme (AMP), led by AfDB, UNDP and Rocky Mountain Institute, do not cover South Africa as a key target country. South Africa could, however, leverage lessons learned, tools and templates developed within these programmes and engage in government-to-government exchanges on strategic approaches and lessons learned in designing legal and regulatory frameworks for microgrids. The African Model Mini-Grid Regulations Toolkit, for instance, was developed by the African Forum for Utility Regulators (AFUR) in partnership with GET.transform to help governments and regulators develop, update and adapt their microgrid policies, regulations and tariff design in line with international best practices.
