A new biofuel cogeneration plant at Vestienas 2, Riga

“Latvijas Energoceltnieks” has commenced the construction of a new biofuel cogeneration plant with the electrical capacity of 4.4 MWe and the thermal capacity of 20 MW.

The new cogeneration plant is designed with the heat boiler of 24 MWth heat capacity and the efficiency coefficient – 88.11 %. The boiler is manufactured by the Danish company “Justsen Energiteknik”. The produced steam is supplied to the steam turbine of the Romanian production “General Turbo”, which, in turn, drives the electric generator, producing the electricity.

The steam produced by the turbine is supplied to the heat exchanger, which heats up the water in the district heating network of Riga that ensures the heat supply for city`s buildings. The remaining steam is condensed and supplied to the boiler, ensuring uninterrupted water circulation.

For the fuel storage purposes closed woodchip storage with 8m high reinforced concrete walls shall be built.

The new biofuel cogeneration plant will ensure:

  • More efficient use of fuel
  • Reduction of emissions
  • Lower energy production costs
  • Reduction of heat losses
  • Promotion of regional development, using local fuel.
