Is Poland moving towards battery energy storage systems (Bess)?

As expected, Poland’s latest capacity market auctions have highlighted a significant shift towards the battery energy storage systems (BESS) beside the fact that the de-rating factor has been significantly decreased.

How many MW rated energy storage systems are there in Poland?

The capacity obligations for these projects ranged from 1.2 MW to 153 MW rated power, with an average capacity of around 30 MW. The decision to reduce the de-rating factor for energy storage systems in the last capacity market auction in Poland from 95 percent to 61 percent did not prove detrimental to the market.

Why is energy storage important in Poland?

With the rising share of intermittent renewable power, large-scale battery storage systems are becoming critical to maintaining grid stability. By addressing challenges such as peak load balancing and frequency regulation, energy storage enhances the resilience and flexibility of Poland’s electricity system.

Is Poland a key player in Europe's energy storage sector?

Poland is emerging as a significant player in Europe's energy storage sector. The recent capacity market auctions in December 2024 highlighted a substantial shift towards BESS, with approximately 2.5 GW secured by new generation capacity market units, predominantly Li-ion energy storage projects.

How much money does Poland spend on battery energy storage?

Poland has finalized a comprehensive subsidy program aimed at accelerating the deployment of battery energy storage systems (BESS), with a total budget of PLN 4 billion (approximately €1 billion).

Why is Poland launching a grid-scale battery system?

The introduction of this storage support program marks a key milestone in Poland’s energy transformation. By enabling the deployment of grid-scale battery systems, the country is strengthening its ability to integrate larger volumes of clean energy, reduce dependence on fossil fuels, and enhance power system stability.
