European IPP R.Power Advances Solar battery storage Systems Co-Located with Solar PV Projects
European independent power producer (IPP) R.Power is making significant strides in the energy storage sector, strategically advancing the development of Battery Energy Storage Systems (BESS) co-located with its extensive portfolio of solar PV projects. This initiative spans multiple key European markets, including Poland, Romania, Germany, Italy, Spain, and Portugal, signaling a major push towards grid stabilization and enhanced renewable energy integration.
A Hybrid Strategy for a Greener Grid with Solar battery storage
R.Power is employing a dual strategy, integrating BESS both as standalone units and in co-located configurations alongside its operational solar farms. This approach is designed to maximize the value and efficiency of its large-scale solar assets. The company’s most advanced construction efforts are currently concentrated in Poland and Romania, where favorable market conditions are accelerating deployment.
In Poland, R.Power has secured over a gigawatt of BESS projects through capacity market auctions held in 2024 and 2025. A notable project under construction is the 150 MW/300 MWh Jedwabne facility. To optimize its market participation, R.Power has entered into a revenue-sharing agreement with Axpo, which will manage the trading activities for the project.
Similarly, in Romania, the 127 MW/254 MWh Scornicesti project is currently under construction. This facility’s revenue will be optimized by GEN-I under a similar floor arrangement, ensuring a baseline of financial stability while capturing market upside.
Navigating Market-Specific Opportunities and Challenges in Solar battery storage
Beyond its core markets in Poland and Romania, R.Power is also expanding its BESS footprint in Italy. The company has two standalone BESS projects, each exceeding 100 MWh, that are nearing the ready-to-build (RTB) stage. These projects are supported by Italy’s MACSE (Mercato dell’Approvvigionamento di CapacitĂ a Termine) capacity market scheme, highlighting R.Power’s ability to navigate and leverage diverse European regulatory frameworks.
However, this rapid expansion comes with procurement challenges. A key hurdle is securing long-term capacity guarantees—spanning 15 to 17 years—from BESS suppliers to align with the duration of government contracts. This requirement often increases upfront costs and can necessitate oversizing projects to account for battery degradation over the contract’s lifetime.
Regulatory nuances between markets also add complexity. For instance, Poland applies a de-rating factor to a battery’s power capacity eligibility in its capacity market, which differs from the approach taken in Italy’s scheme.
A Financially Sound Approach to Scaling Solar battery storage
R.Power’s BESS strategy is underpinned by a financial model that relies on long-term revenue streams from capacity markets combined with sophisticated optimization deals. This positions the company to effectively scale its energy storage operations amid the growing European demand for grid flexibility. While R.Power occasionally sells projects, its primary strategy is to retain the majority of assets within its own portfolio, building a robust and long-term operational base. By pairing solar generation with battery storage, R.Power is not only future-proofing its assets but also playing a crucial role in enabling a more resilient and renewable-powered European grid.
