Czech Republic — Energy Infrastructure
OverWatts maps 79 energy assets in Czech Republic across 8 layers — the 73rd-largest mapped base of 157 countries. They include 45 power plants, 9 pipelines and 8 interconnectors. Operating generation capacity is 13.9 GW, led by coal at 53%.
The companies named on the most assets are CEZ AS (26), Net4Gas (9) and ČEZ Group (7), counting both ownership and operatorship. Half of Czech Republic's mapped assets in service predate 1970 (median commissioning year of the 35 with a known date), 1 came online in the past decade and the oldest still listed is Bilina Coal Mine, dating from 1947. 20 projects are under construction or proposed, led by Temelin nuclear power plant (2.4 GW).

Operating generation capacity by fuel
Utility-scale sites of 100 MW and above. Distributed generation — rooftop solar especially — is outside the tracker, so this runs below national installed capacity.
