Polish renewable energy company R.Power said it has expanded its partnership with Eiffel Investment Group through two new transactions involving solar and battery energy storage projects in Poland and Romania.
The deals cover 92 megawatts peak (MWp) of photovoltaic assets in Poland and 127MW / 254 megawatt-hours (MWh) of battery storage projects in Romania. As part of the transactions, R.Power will divest a minority stake in both project portfolios.
In addition, the companies plan to broaden their Polish joint venture to include a new hybrid portfolio combining up to 56MWp of solar generation capacity with 51MW of energy storage.
R.Power said the new agreements mark another step forward in its collaboration with Eiffel, aimed at advancing the integration of renewable generation and flexible storage technologies across Central and Eastern Europe.
Chief Executive Przemek Pieta said the continued partnership demonstrates the growing trust between the two companies and their shared long-term vision.
“The extension of our joint venture with Eiffel is a strong sign of trust and the maturity of our partnership,” Pieta said. “Together, we are building an integrated portfolio that combines photovoltaic generation with battery storage — a model that will shape the future of clean energy.”
Pierre-Antoine Machelon, head of infrastructure at Eiffel Investment Group, said the deal aligns with Eiffel’s strategy of supporting renewable expansion in emerging European markets.
“This transaction perfectly reflects our vision: investing into the deployment of additional renewable capacity alongside flexible systems in Europe, in countries where it is highly needed such as Poland and Romania,” Machelon said.
R.Power added that the partnership highlights its growing presence in hybrid renewable projects, with a development pipeline exceeding 30 gigawatts (GW) across six European markets.
The company said the collaboration with Eiffel positions both partners to play a key role in advancing energy transition efforts and improving grid flexibility in the region.
