Kenya puts a price on illegal solar power flowing into the grid

Kenya has introduced a solar dumping charge for homes and businesses that send electricity into the Kenya Power network without the required approval, tightening controls around private power generation as more consumers install solar systems to reduce their reliance on the utility.

The Energy and Petroleum Regulatory Authority (EPRA) amended Kenya Power’s electricity tariff schedule through a Gazette Notice published on September 18, 2026. The amendment formally defines unauthorised electricity injected into the utility’s network as “dumping” and provides that the electricity will be measured and charged at the applicable base tariff. It also leaves room for further action where the dumping causes injury or damage to equipment.

The change does not mean that every household or business with solar panels is subject to a new penalty. Kenya already has a legal framework allowing eligible consumers to export surplus renewable electricity through net metering. The issue is whether a generating system has been approved for that purpose and is operating under the required agreement with the electricity licensee.

Kenya’s new solar dumping charge explained

Under the new tariff provision, electricity pushed into the Kenya Power network without prior written authorisation can be treated as dumping. The provision is aimed at customers whose generating systems feed power into the distribution network without approval or without a valid net-metering agreement.

That distinction is important for consumers because a solar installation can be connected to a building without being authorised to export electricity to the grid. A system designed for self-consumption and backup can therefore raise a different regulatory question if its inverter allows electricity to flow back through the customer’s connection into Kenya Power’s network.

The new charge is also different from the existing offence provisions under the Energy (Net-Metering) Regulations, 2024. Those regulations require an eligible consumer to enter into a net-metering agreement before operating a net-metering system, while unauthorised connections and unauthorised alterations can attract statutory penalties.

The September amendment therefore adds a tariff consequence to the regulatory framework. Electricity classified as dumped is to be charged at the applicable base tariff, while EPRA or Kenya Power can take further action where the unauthorised injection damages equipment.

Net metering gives solar owners a legal export route

Kenya’s net-metering framework was established in 2024 to allow consumers generating renewable electricity for their own use to send surplus power to the grid and receive credits against electricity consumed later.

The regulations cover renewable-energy systems below 1 MW, although domestic consumers have lower capacity limits of 4 kW for single-phase supply and 10 kW for three-phase supply. Commercial and industrial customers can have systems of up to 1 MW, subject to their maximum demand and other conditions in the regulations. The initial aggregate capacity for net-metering systems was set at 100 MW for the first five years.

The arrangement works through a two-way meter that records electricity supplied by Kenya Power and electricity exported by the customer. For every unit exported during a billing period, the consumer receives a credit equivalent to 50 percent of the exported unit. Any excess credit can be carried into subsequent billing periods, although unused credits are forfeited at the end of the licensee’s financial year.

That means net metering is not the same as selling every excess unit to Kenya Power for cash. A customer exporting 100 kWh receives an energy credit equivalent to 50 kWh, which can then offset electricity supplied by the utility under the applicable billing arrangements.

For systems above 10 kW, the application also requires a feasibility study prepared by an engineer. The customer must receive approval and enter into the required agreement before the system operates as a net-metering installation.

Why Kenya Power is concerned about uncontrolled solar exports

The regulatory issue sits within a wider change in Kenya’s electricity system. Solar generation is no longer confined to large power plants. Commercial buildings, factories, institutions and households are installing generation behind the meter, creating a growing layer of electricity production that can operate alongside the utility network.

Kenya Power has separately warned that the growing share of variable renewable energy creates operational challenges because wind and solar output can change with weather conditions. At peak demand, the utility said wind and solar had accounted for 34 percent of the energy mix, while it has also called for greater attention to grid stability and the cost of balancing variable generation.

Unauthorised exports add a different problem because distribution networks have to account for where electricity is coming from as well as where it is going. An approved grid-connected solar system can be assessed for its technical characteristics, metering, protection arrangements and impact on the network. An unapproved system removes that visibility.

There is also a worker-safety issue. Kenya Power has warned that unauthorised connections can expose technicians and engineers to electrical hazards during network maintenance, particularly where a section of the network is expected to be isolated but an improperly connected generation system can feed electricity back into it.

That makes the dumping provision part of a broader grid-management problem rather than simply a billing dispute between a solar owner and Kenya Power.

Solar growth is changing how Kenya manages electricity

Kenya’s electricity system already has to manage substantial amounts of variable renewable generation. Kenya Power has said wind and solar can make up a large share of supply at particular points in the day, while their output does not necessarily coincide with the hours when electricity demand is highest.

EcoNews has previously reported on the push for smarter grids and energy storage as renewable generation grows. Discussions at the Kenya Energy Transition Forum 2026 highlighted battery storage, digital grid management, improved forecasting and power electronics as tools that can help the system handle fluctuations in renewable generation.

The same principle applies at a smaller scale behind the meter. A business with solar panels may generate more electricity than it needs at midday, then require power from Kenya Power later in the evening. Batteries can keep more of that generation within the customer’s premises, while an approved net-metering arrangement provides another route for surplus electricity that reaches the distribution network.

The regulatory challenge is to make those two-way flows visible and controllable. As private generation grows, the distinction between a customer that merely consumes electricity and one that also supplies it becomes more important to the operation of the distribution network.

The unresolved question over the July 2025 effective date

One of the most significant details in the September notice is its effective date. Although the amendment was published on September 18, 2026, reports on the notice say its provisions were made effective from July 1, 2025.

That creates a question for solar owners and businesses that installed systems during the intervening period. It is not yet clear from the publicly available material whether Kenya Power intends to identify and retrospectively bill unauthorised exports made during that period, or how such exports would be calculated.

A September 22 report by pv magazine said EPRA had not issued enforcement notices or retroactive billing advisories under the new dumping definition at the time of publication.

The distinction is important because the regulatory framework and the enforcement of that framework are separate questions. A rule having an earlier effective date does not by itself establish how Kenya Power will identify historical exports or what evidence it would use to calculate a customer’s exposure.

What the new rules mean for solar owners

For households and businesses with grid-connected solar systems, the first question is whether the installation can export electricity into Kenya Power’s network. If it can, the owner needs to establish whether the system has the required approval and a valid net-metering agreement.

A customer using solar strictly for self-consumption and backup faces a different situation from one intentionally exporting surplus generation. The important technical details include the inverter configuration, the connection arrangement, the meter installed at the premises and whether the utility has authorised electricity to flow in both directions.

The new rule also gives greater importance to batteries and other forms of energy management. A system that stores excess daytime generation can reduce the amount of power sent back to the grid, while approved net metering provides a regulated mechanism for customers that want to export eligible surplus electricity.

Kenya’s solar market is therefore entering a more regulated relationship with the electricity network. Private generation can reduce demand on the utility and help businesses manage their energy costs, but once electricity crosses back into the distribution system, technical, safety and commercial rules apply. The new dumping charge puts a financial consequence around one part of that boundary while leaving the wider task of integrating distributed generation to Kenya’s grid operators and energy regulators.
