At Solarplaza Summit Poland, industry leaders agreed: Poland needs battery storage, but major obstacles are slowing deployment. The country is working to phase out coal by 2050, but without rapid storage expansion, grid reliability and renewable integration will suffer.
Here’s what’s holding BESS back and what needs to happen next.
Grid Connection Delays Are Stalling Projects
Poland’s long wait times for grid connections are a serious problem. Developers are stuck in limbo, unable to move forward while grid infrastructure struggles to keep up.
What this means for the market:
Uncertain project timelines make investment planning difficult.
Slower renewable adoption, limiting Poland’s energy transition progress.
Growing demand for alternative flexibility solutions like demand response and local trading.
BESS Profitability Is Under Threat
Poland currently applies a 61% de-rating factor to BESS, meaning only a portion of its capacity is considered useful for grid services. Worse, this may drop further in the next five years as Poland’s TSO (PGE) prioritizes natural gas over storage.
What this means for the market:
Lower returns on BESS investments, discouraging new projects.
Policy uncertainty makes it harder for developers to plan for the future.
Storage must prove its value faster to secure its place in the energy mix.
Lack of Market Transparency Is Keeping Investors on the Sidelines
One of the biggest barriers to BESS deployment is the lack of clear revenue data. Without transparency into Poland’s electricity markets, developers and investors are making high-risk decisions with no clear view of profitability.
What this means for the market:
Investors hesitate to commit capital without reliable revenue forecasts.
Developers struggle to optimize projects without full market visibility.
Better financial data and forecasting tools are critical for storage to scale.
How GreenVoltis Helps Developers Cut Through the Uncertainty
At GreenVoltis, we provide:
✔️ Clear market revenue insights so developers and investors know where and how BESS makes money.

Poland Needs Storage – But the Industry Needs More Clarity
The demand for storage is there, but grid constraints, weak financial transparency, and unstable market rules are slowing growth. Until these problems are fixed, BESS adoption in Poland will remain slower than it should be.
At GreenVoltis, we’re working to solve these issues so storage developers and investors can move forward with confidence.
