GoldenPeaks Capital Expands Strategic Battery Energy Storage Portfolio in Poland with Two New Acquisitions
GoldenPeaks Capital (GPC), one of Europe’s fastest-growing independent producers of green energy, has significantly strengthened its presence in the battery energy storage market through the successful acquisition of two new Battery Energy Storage System (BESS) projects in Poland. These projects, secured under a preliminary share purchase agreement, add a combined capacity of 54 megawatts (MW), equating to 216 megawatt-hours (MWh), to GPC’s growing portfolio of flexible energy solutions.
The acquisition marks another major milestone in GPC’s ambitious growth strategy within the energy storage space. As renewable energy deployment accelerates across Europe, driven by both regulatory incentives and the urgent need to decarbonize power systems, battery storage is emerging as a critical enabler of grid stability, reliability, and flexibility. Recognizing this, GPC has made BESS development a cornerstone of its long-term energy transition strategy.
Capacity Market Success Reflects Strategic Foresight
The two newly acquired BESS projects have already proven their commercial viability and strategic relevance by winning 17-year contracts in Poland’s 2024 Capacity Market auction. Designed as 4-hour energy storage systems, these projects were awarded the highest available capacity payments under the scheme, highlighting their value in supporting the grid during peak demand periods.
The Polish Capacity Market, established to ensure long-term energy security and grid reliability, rewards power assets that can deliver firm capacity when required. GPC’s success in securing the maximum capacity payments underscores not only the quality of the assets themselves but also the company’s ability to identify and capitalize on favorable market mechanisms in a highly competitive energy landscape.
Project Details and Grid Integration
The larger of the two projects, located in Baczyna, boasts a nameplate capacity of 46 MW with an energy capacity of 184 MWh. This installation will connect to the national transmission network at the 110 kV high-voltage level, enabling it to serve as a substantial balancing resource for the grid.
The second project, situated in Jelenia Góra, adds an additional 8 MW and 32 MWh of storage capacity. This system will be connected to the 20 kV medium-voltage network, making it ideally suited for more localized grid services and regional energy optimization.
By developing systems with both high- and medium-voltage grid connections, GPC is strategically positioning itself to provide flexible services across multiple levels of the power infrastructure. These services may include frequency regulation, peak shaving, energy arbitrage, and the integration of variable renewable generation.
Strategic Transaction and Expert Collaboration
The transaction was formally closed on June 6th, following a rigorous six-week due diligence and negotiation process. The acquisition effort was led by the team at Mercer, with Damian Majkowski at the helm, ensuring a detailed assessment of the technical, legal, and financial dimensions of the projects.
Commenting on the successful completion of the deal, Adriano Agosti, Founder and Chairman of GoldenPeaks Capital, stated:
“This is a great example of dedicated teamwork between Mercer, Spectris, and GoldenPeaks Capital, each contributing their own specialized knowledge and capabilities. The successful acquisition of these two projects reinforces our vision of making BESS a strategic pillar within our green energy portfolio. It also demonstrates our continued commitment to investing in transformative technologies that support Europe’s transition to a resilient, decarbonized energy system.”
This collaborative approach not only ensured that the transaction proceeded efficiently and transparently, but also set a precedent for future acquisitions as GPC continues to build out its BESS portfolio in Poland and other core European markets.
Expanding BESS Portfolio and Long-Term Vision
With the addition of these two projects, GoldenPeaks Capital’s current portfolio of BESS projects in Poland now totals 124 MW, positioning the company as a significant player in the Polish energy storage market. This expansion is fully aligned with GPC’s long-term goal of diversifying its clean energy assets and enhancing grid resilience through investments in energy flexibility technologies.
BESS has rapidly gained momentum as a key tool for managing the intermittency of renewable energy sources such as solar and wind. By storing excess energy produced during periods of low demand and discharging it when demand peaks, battery storage ensures that renewable energy can be reliably integrated into the power system without compromising stability.
Moreover, the importance of energy storage in supporting decarbonization, grid modernization, and energy independence is being recognized across Europe. GPC’s investments in BESS reflect not only a commitment to financial returns but also a deep alignment with the broader goals of the European Green Deal and national energy transition plans.
Market Timing and Long-Term Incentive Advantage
Notably, the capacity market payments secured by these projects represent some of the final instances of heavily subsidized support for BESS projects in Poland. As regulatory frameworks evolve and capacity mechanisms become more competitive, the ability to secure such long-term payment structures offers GPC a unique strategic advantage.
These 17-year capacity agreements provide a stable revenue stream that underpins the financial sustainability of the projects and enhances their appeal to future investors or financial partners. The secured payments also enable GPC to confidently pursue further innovations in operational efficiency, asset optimization, and energy trading capabilities.
This timing advantage places GPC at the forefront of the Polish BESS market, well-positioned to lead future development and potentially shape industry standards and best practices.
BESS as a Strategic Pillar
GoldenPeaks Capital’s acquisition of the Baczyna and Jelenia Góra BESS projects represents far more than a simple portfolio expansion—it is a clear signal of the company’s strategic intent. By embracing energy storage as a core component of its operations, GPC is actively transitioning from a traditional renewables developer to a fully integrated clean energy platform capable of delivering firm, dispatchable, and grid-supportive services.
As energy markets become increasingly decentralized and demand more adaptable infrastructure, companies that can offer both generation and storage will have a significant edge. GPC’s foresight in building this capability early on reflects a deep understanding of market trends and a willingness to lead rather than follow.
In the coming years, GPC is expected to continue investing in innovative energy storage technologies, forging strategic partnerships, and expanding its geographic reach. Whether through additional acquisitions, greenfield development, or joint ventures, the company remains focused on delivering high-impact energy solutions that support both economic growth and environmental sustainability.
