The National Fund for Environmental Protection and Water Management (NFOŚiGW) in Poland has released the results of its call for proposals under the priority programme aimed at improving the stability of the Polish power grid through electricity storage facilities and related infrastructure.

The ranking list, prepared according to accessibility and quality criteria, determines which projects will be invited to negotiate funding terms.

Placement on the list does not guarantee financial support. Applicants will receive details of proposed funding amounts and next steps in the coming days. Contract signing is earmarked for before the end of December.

R.Power was named among the largest potential recipients with the group lining up both a grant and loan for its PLN 542.7m (EUR 128.3m) Dzięgielewo storage project in Masovian Voivodeship, as well as similar awards for its PLN 445.2m (EUR 105.3m) Tursko Wielkie project in Świętokrzyskie and similarly sized Gdansk II facility in Gdansk.

Meanwhile, Greenvolt is in line for a grant for its PLN 496m Turośń Kościelna battery in Podlasie, alongside several other projects, and EDF is being allocated a grant for its PLN 361.2m (EUR 85.4m) Turzyn site in Masovian Voivodeship.

Other developers named among the potential recipients of financial support include Tauron with several projects led by its 84 MW Maryszów BESS in Silesia, Equinor (Chałupki, Lipno and Zagórzyca projects), Iberdrola, Green Capital (led by 80 MW facility in Silesia), and PGE (several assets).

Other awardees include EDPR, IB Vogt, Polenergia, ZGH Boleslaw, JF Invest, Projekt Solartechnik, Insun, EGN Energy, Sunly, Neo Energy Group, Grupa Energa, Emeren, CMC-Oil, PEI Group, JinkoSolar, Domrel, R2 Energy, FRV, M&R Company, Trans-Kol, Ener Polska, Grenergy, Energylandia, Enea Nowa Energia, Polska Energia Odnawialna, Walbet, WMC PV, ZPK, EWG. Eletrownie Wiatrowe, RWE, and Orlen, among others.

The programme follows the European Commission decision on state aid support under the Temporary Crisis and Transition Framework (TCTF) and Recovery and Resilience Facility (RRF), which sets conditions for support for electricity storage and associated infrastructure. Funding allocation prioritises projects with the highest scores within the available budget. Those at the lower end of the ranking may receive proportionally reduced amounts. In cases of equal scores, readiness for implementation and submission date determine the order.

Technical design and documented rights to use land for both the storage facility and grid connection were mandatory for points to be awarded.

Environmental decisions were also assessed, with points granted for submitted approvals or refusals to initiate proceedings.

The evaluation included a standardised methodology for calculating environmental impact. For collocated storage facilities integrated with renewable generation, avoided CO₂ emissions were calculated based on energy that would otherwise be curtailed and later discharged during off-peak hours.

For stand-alone facilities connected to the National Power System, emissions reduction was estimated using differential emission factors between charging and discharging periods.

Annual energy throughput assumptions included one cycle per day, 328.5 operating days per year, and 90% storage efficiency. These figures were used to determine the amount of energy released to the grid and the corresponding emissions savings.
