Salaspils, Latvia

The combined heat and power (cogeneration) plant in Salaspils, a city near capital Riga in Latvia, is a highly efficient wood-fired CHP with a high pressure (52 bar) water tube steam boiler of 20 MWt and a 4.5 MWe steam turbine. The plant provides electricity and heat to the local district net. This equates to the consumption of approximately 15,000 households.

Pruning waste is used as fuel to produce heat and electricity. The flue gases that are released during combustion of the pruning waste flow into the boiler. In turn, the boiler produces steam that powers the steam turbine which then again produces electricity.
