GoldenPeaks Capital acquires two battery storage projects in Poland totaling 216 MWh

Both projects secured 17-year Capacity Market contracts in Poland’s 2024 auction. With four-hour durations, they achieved the maximum allowable capacity payment for battery energy storage system (BESS) assets.

GoldenPeaks Capital (GPC) has acquired two new battery energy storage system (BESS) projects in Poland with a combined capacity of 54 MW / 216 MWh, continuing the company’s rapid expansion into energy storage across Central and Eastern Europe.

The projects, Baczyna (46 MW / 184 MWh) and Jelenia Góra (8 MW / 32 MWh), were acquired under a preliminary share purchase agreement that was finalized on June 6 following a six-week due diligence and contract negotiation period led by the Mercer acquisition team, headed by Damian Majkowski.

Both projects secured 17-year Capacity Market contracts in Poland’s 2024 auction. As four-hour systems, they achieved the maximum allowable capacity payment for BESS assets. GPC states that the “17-year capacity market payments from these projects represent the last heavily subsidised BESS payments in Poland, positioning GPC well for long-term project success.”

Adriano Agosti, founder and chairman of GPC said that both projects show the company’s commitment to BESS.

“This is a great example of a dedicated teamwork between Mercer, Spectris and GoldenPeaks Capital, combining their individual expertise,” Agosti said.

“It also shows GoldenPeaks Capital’s commitment to further strengthen BESS as a strategic pillar.”

The 46 MW / 184 MWh Baczyna project will connect to the high-voltage grid at 110 kV, while the 8 MW / 32 MWh Jelenia Góra project will connect to the medium-voltage network at 20 kV. The latest acquisition brings GPC’s total BESS portfolio in Poland to 124 MW.

In January this year, GPC announced a battery storage-focused strategy, targeting a 600 MWh portfolio expansion in 2025.

When will there be nationwide financing solutions for battery storage systems in Germany? The use of battery storage systems is essential for the success of the energy transition and the best possible use of renewable energies, but also for being able to temporarily store surplus energy from other sources. Technically, there are already solutions for all possible sizes of battery storage systems, from private home storage systems to large-scale storage systems with a capacity of more than 50 MWh. But what about the financing of battery storage systems, is it already offered as standard?

Voltwise: Extend German grid fee exemption for large batteries to 2034 Germany's Federal Network Agency is consulting on a proposed overhaul of its grid fees to introduce a General Grid-Fee System (AgNES). Battery energy storage systems (BESS) are currently exempt from the charges and Voltwise's head of German operations, Thorsten Klöpper, is suggesting a three-stage system which takes account of battery-related grid benefits.

Falling li-ion battery prices mirror solar photovoltaics trends: Is there a role for second-life batteries before recycling? Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.
