On 9 March 2026, the President signed Law No. 4777-IX. The law amends the regulation of auction-based support for renewable energy producers, grid connection, energy storage, guarantees of origin, and the situation with assets located on occupied territories. The Cabinet of Ministers is required to bring its acts into compliance within two months; the energy regulator NEURC has six months to do so.
Under the auction support model, the provision requiring producers to return to the Guaranteed Buyer the price difference when the market price exceeds the auction price has been abolished. The mandatory annual support quota by renewable energy type has been reduced to 5% (previously 10%), with a separate quota of at least 10% established for solar power plants combined with energy storage. The maximum bid price for solar-plus-storage projects has been capped at €0.12 per kWh. The financial security requirement for contract performance has been reduced to €10/kW (previously €15), and the security for construction timeline extensions to €10/kW (previously €30). An alternative financial security instrument has been introduced: a guarantee deposit to the Guaranteed Buyer’s account or an escrow account held by the auction participant. The auction period has been extended to 31 December 2034.
Flexible connection to the transmission or distribution system has been introduced as an alternative to network reconstruction or new construction where capacity is insufficient. Customers have been granted the right to connect different types of electrical installations at a single connection point, covering generation from any source, storage, and consumption. Cable pooling has been extended to energy storage operators and consumers, who may now connect their own electrical installations to the networks of another producer, storage operator, or consumer.
Producers installing energy storage at their generation site are now entitled to pay transmission and distribution tariffs only on the net difference between the monthly withdrawal and injection of electricity by that storage unit. Mandatory purchase hours have been defined during which the Guaranteed Buyer is obliged to offtake electricity from solar plants: 04:00 to 23:00 from 1 April to 31 October, and 06:00 to 21:00 from 1 November to 31 March. Biomass and biogas producers have gained expanded rights to supply electricity to their own facilities and those of related persons located beyond directly adjoining land.
Licensing of energy storage activity is mandatory where the installed capacity of a storage unit at a single metering point exceeds 5 MW. Storage operators have been granted the right to install generating units at their licensed activity site without obtaining a separate generation licence.
Producers receiving support under the feed-in tariff or market premium mechanism are required to transfer all guarantees of origin for the relevant assets to the Guaranteed Buyer.
40% of the funds received by the transmission system operator from the allocation of cross-border transmission capacity in 2025 shall be directed towards settling arrears owed to the Guaranteed Buyer. The Guaranteed Buyer is obliged to proportionally redistribute those funds to Energoatom and to producers that were part of its balancing group.
To address the situation with renewable energy assets on temporarily occupied territories, a Special Commission is to be established within 30 days of the law’s entry into force. It will comprise representatives of the regulator, the Security Service of Ukraine, the Ministry of Energy, the Ministry of Reintegration, the State Energy Supervision Service, the transmission system operator, and distribution system operators. The Commission will approve a list of such assets specifying the dates on which electricity supply to the controlled part of Ukraine’s integrated power system was suspended and resumed, on the basis of which the transmission system operator will compile the relevant register. Producers are required to return funds paid by the Guaranteed Buyer for periods during which no electricity was supplied.
