Annual Report 2014 | Suomeksi |

Combined heat and power production

Fortum prefers combined heat and power (CHP) production, which utilises as much as 90% of the fuel’s energy; by comparison, the efficiency of electricity-only production is about 60% at its best. We use different fuels in a diverse and flexible manner in CHP production.

In 2014, CHP plants accounted for 90% of Fortum’s heat production and 28% of its electricity production. We produce electricity, heat and steam at 20 CHP plants in Finland, Poland, Russia and the Baltic countries. During the past two

years, we have commissioned new CHP plants in Finland, Latvia and Lithuania. Additionally, energy-efficient gas turbine units were taken into use at the Chelyabinsk CHP-1 power plant in Russia. Two more natural gas-fired CHP plant units were under construction in Russia in 2014. Upon completion in 2015, they will increase Fortum’s electricity production capacity by 496 MW and its heat production capacity by 350 MW.

Joint venture Fortum Värme produces electricity and heat at four CHP plants in the Stockholm region. The Brista power plant’s new CHP unit was commissioned in 2014. Fortum Värme is constructing a new biomass-fired CHP plant in Stockholm. The plant is scheduled to be completed in 2016. The plant’s electricity production capacity is 130 MW, and its heat production capacity 280 MW. It will replace Fortum Värme’s old coal-fired capacity.

Availability of CHP plants at a good level

Good availability of a power plants enables efficient and safe operation, a reliable supply of energy and reduced environmental impacts. The average availability of Fortum’s CHP plants in 2014 was 94.7%; the annual target was 95%.

We are continuously engaged in projects to improve power plant availability and reliability. In 2014, we upgraded fuel-feed systems, water-steam cycles, and electrical and automation systems, among other things.
