Grenergy Accelerates BESS Expansion in Romania and Poland
Spanish renewable energy company Grenergy is significantly expanding its battery energy storage system (BESS) footprint in Central and Eastern Europe. The developer is currently advancing projects with a total capacity of 236 MW/944 MWh across Romania and Poland, marking a strategic shift towards hybrid projects that combine generation with storage to maximize asset value and grid integration.
Flagship Projects in Romania and Poland
In Romania, Grenergy is developing the flagship 'Lebăda' project, which will feature a substantial capacity of 204 MW/816 MWh with a 4-hour storage duration. The company is in advanced negotiations for a Power Purchase Agreement (PPA) and intends to apply for funding from the EU Modernisation Fund. Construction is slated to begin in Q1 2027, with operations commencing in Q3 2028. Simultaneously, in Poland, Grenergy is developing two BESS systems with a cumulative capacity of 32 MW/128 MWh. These projects are scheduled to become operational by the end of 2027, and the company successfully secured capacity contracts in the Polish market during the first half of 2026.
Both the Romanian and Polish projects are planned to reach ready-to-build (RTB) status by the end of Q1 2027 and have entered the backlog stage with a 90% execution probability, providing high visibility for future revenue streams.
Strategic Financial Growth and Portfolio Goals
This regional expansion is backed by strong financial performance. In H1 2026, Grenergy reported revenues of €661 million, a 51% year-on-year increase, alongside a net profit of €74 million. Capital expenditures rose by 25% to €275 million, primarily directed towards these hybrid projects. The strategic focus on Central and Eastern Europe highlights a broader trend of developers seeking out emerging markets with high growth potential.
"Grenergy aims to reach 8 GWh of operational or under-construction projects by 2028 via its European Greenbox platform."
Through its European Greenbox platform, Grenergy now boasts a regional BESS portfolio of over 9 GWh in Romania and Poland. By securing capacity contracts and advancing projects to the ready-to-build stage, Grenergy is positioning itself to capitalize on the increasing demand for grid flexibility in regions rapidly expanding their renewable generation capacity.
