Chapter 1 · Energy
Gas and rooftop solar
Interactive 8 min
Two numbers open the energy chapter. On 29 September 2026 gas storage was 99% full, about 3.3 billion cubic metres [1]. At the end of 2025 Poland counted 1,636,673 renewable micro-installations, about 13.9 GW, mostly rooftop solar [2].
Try this. Open the figures panel and compare capacity with output. Why can 13.9 GW of capacity give 8.95 TWh in a year? Think about nights and winter.

Where the energy comes from
A pipe from the Norwegian shelf, solar panels on the roofs, the first offshore wind farm and a farming sector that feeds its neighbours.

Gas storage is 99% full
On 29 September 2026, Gas Storage Poland reported its facilities 99% full, about 3.3 billion cubic metres of working gas. The gas arrives through the Baltic and the North Sea: Baltic Pipe from Norway, up to 10 bcm a year since October 2022, and the Świnoujście LNG terminal, expanded to 8.3 bcm a year in January 2025.
1.6 million power stations on Polish roofs
At the end of 2025 Poland had 1,636,673 renewable micro-installations, mostly rooftop solar, with about 13.9 GW of capacity. In 2025 they fed 8.95 TWh into the grid. The regulator counts over 1.61 million prosumers: households that both use and make electricity. Each light on the map stands for 10,000 installations.
