CHP plants have a high level of availability enabling uninterrupted energy production. At the same time the plants can be highly automated, thus minimising the number of staff required and also cutting the costs of operations and maintenance. The electricity and heat output can be adjusted in a flexible manner according to need, which may sometimes change at short notice. Example: Flexible adjustments: the Rauhalahti Plant

CHP technology allows quick and flexible adjustment of the electricity
to heat generation rate as well as the total otput. The Rauhalahti
CHP Plant generates electricity, district heating and process steam.
It was comissioned in 1986. In 1993 the boiler was converted from
pulverised firing to bubbling fluidised bed combustion. The plant is
the largest biomass fired CHP plant in the world.
