Production of electricity (in terms of power) by power plants connected to the National Power Grid in 15-minute resolution. Net power is measured at the point of connection to the electricity grid and is equal to gross power minus power plant’s own consumption and losses at the output.
Emissive energy sources: hard coal, lignite, natural gas, biomass, other (oil, coke-oven gas, other unspecified).
Non-emissive energy sources: onshore wind, photovoltaics, hydroelectric power plants (run-of-river, reservoir), energy storage (currently pumped storage).
The data is published by ENTSO-e, but originates from the Transmission System Operator (Polskie Sieci Elektroenergetyczne) on the basis of continuous readings of the power at which the individual units operate.
