Technical FAQs 4

What is a co-located battery energy storage system (BESS) project?

Co-located Battery Energy Storage System (BESS) Projects Battery Energy Storage Systems offer flexible and rapid response capabilities crucial for real-time grid management. The Ministry has announced a 100% ISTS charges waiver for co-located BESS projects commissioned on or before June 30, 2028.

Why are energy storage systems important?

Energy storage systems are increasingly recognized as indispensable for managing the intermittency of renewable sources like solar and wind, ensuring grid stability, and providing reliable power supply, especially during peak demand periods.

What is the new electricity storage law in Poland?

It also ensures a tariff framework for storage that is non-discriminatory and cost-reflective. With these measures, the amended law removes regulatory barriers to the development of electricity storage in Poland. The reform entered into force in 2021. More information can be found on the webpage of the Ministry Climate and Environment here.

What is the purpose of electricity storage reform?

The objective of this reform is to facilitate the development of electricity storage by creating the necessary legal framework.
