💨 Onshore Wind: Repowering and New Projects

Onshore wind energy in Poland has experienced a renaissance following the liberalization of the 10H rule in 2023, which previously required turbines to be located at a distance of at least ten times their height from residential buildings. The new regulations reduce this distance to 700 meters for modern turbines, unlocking vast areas for development.

Repowering Aging Wind Farms

Many of Poland’s first-generation wind farms, built between 2005 and 2012, are approaching the end of their operational life. Repowering — replacing older turbines with fewer, more efficient models — can increase capacity by 2-3 times while reducing visual impact. Several projects in the Pomeranian and Warmian-Masurian regions are already underway, with total repowering potential estimated at 3 GW.

New Onshore Wind Developments

The pipeline of new onshore wind projects has grown significantly. As of early 2025, over 8 GW of projects are in various stages of development, from permitting to construction. The average turbine size for new installations is now 5-6 MW, with hub heights exceeding 120 meters to capture stronger winds at higher altitudes.

⚠️ Challenge: Grid connection remains a major bottleneck for both new wind farms and repowering projects. Developers are increasingly partnering with BESS providers to offer grid services and reduce curtailment risk.

🔋 BESS: The Missing Link in Poland’s Energy Transition

Battery energy storage systems (BESS) are arguably the hottest trending topic in Polish renewable energy right now. As solar and wind penetration increases, the need for grid stability and time-shifting of renewable generation has become critical. Poland’s BESS market is expected to grow from 0.5 GW in 2024 to over 5 GW by 2028.

Large-Scale BESS Projects

Several utility-scale BESS projects have been announced or are under construction. Notable examples include a 200 MW/400 MWh system in the Silesia region and a 150 MW/300 MWh project in the Lubuskie region. These systems provide frequency regulation, capacity firming, and arbitrage services. Developers are also exploring second-life applications for EV batteries.

BESS + Solar Hybrid Parks

Combining solar PV with BESS is becoming the default configuration for new projects. Hybrid parks offer several advantages: smoother power output, reduced grid connection costs (shared infrastructure), and higher capacity factors. Green Poland is actively developing several hybrid projects with co-located storage, targeting a total capacity of 500 MW by 2027.

Regulatory Support for Storage

The Polish government introduced a new support mechanism for energy storage in 2024, including capital grants of up to 30% for large-scale BESS projects and simplified permitting for standalone storage. Additionally, the capacity market now allows BESS to participate as a demand-side response resource, providing a stable revenue stream.

Technology Installed Capacity (2024) Projected Capacity (2028) Key Driver
Solar PV 20 GW 30 GW Falling module costs
