The total capacity of these smallest RES microinstallations is more than 12.7 GW. It was another year that the URE saw a decreasing growth in the number and capacity of these facilities. The predominant energy volume (99.7 percent) exported to the grid still originates from PV arrays, with more than 98 percent of these microinstallations owned by prosumers.
This is the current RES landscape depicted in the URE Report on RES microinstallations. It is a summary driven by the annual reports from energy distributors who list the numbers of on-grid RES microinstallations. Microinstallations are the smallest power generating units, each with a maximum total installed capacity limited to 50 kW.
As reported at the end of 2024, there were 1,544,574 on-grid microinstallations in Poland with a total capacity of 12,749.891 MW. In 2024, all microinstallations exported more than 8.5 TWh to the grid.
Most RES microinstallations (nearly 98.6 percent) are owned by prosumers, totalling at 1,522,655 in Poland. They were nearly 95 percent of the power (12,045 MW) and 97.2 percent of the energy exported into the national grid from all RES microinstallations (8.318 TWh). It was the second year in succession that the share of prosumers in RES microinstallation energy generation volume shrank (98.1 percent in 2022 and 97.7 percent in 2023).
According to the data available at the end of 2024, two third of prosumer-owned RES microsinstallations (more than 1 million) were on the distribution grids of two DSO's, Tauron Dystrybucja and PGE Dystrybucja. The grids of these two DSO's received two third of the energy export from the smallest RES installations.
The data for the year 2024 suggests that a decline continues in the growth rate of RES microinstallation number and their energy export to the grid. The number of RES microinstallations grew by approx. 41 percent YtY in 2022, approx. 15 percent YtY in 2023 and merely 10 percent YtY in 2024. Their energy export volume grew by as much as 110 percent in 2022, 26 percent in 2023 and approx. 17 percent in 2024. The URE witnessed a falling growth rate of RES microinstallation capacity, which grew by 52 percent in total in 2022, 22 percent in 2023, and 12 percent in 2024.
2024 was the first year in Poland when three RES microinstallations owned by prosumer collectives were officially registered. Their total capacity was 0.113 MW, and the total energy output exported to the grid was 87.768 MWh.
