Sora / Centrale Termoelettrica

Primary Energy Necessary 50,162 TEP
Electricity used in the plant 137,536 MWh
LV Steam used in the plant 341,630 t
Electricity sold to the market 59,346 MWh

In 2008 a cogeneration plant was installed to provide for the deficit in energy production in terms of the needs of the plant. The new turbogas generator was designed to integrate in a combined cycle with the two existing steam turbines. The plant now provides all the technological steam required by the paper mill. Any excess electricity generated is yielded to the grid.

Power Plants
