Wärtsilä believes the Finnish energy system should be developed by increasing wind power generation substantially and discontinuing the nuclear power plant projects in Loviisa and Pyhäjoki, reports Helsingin Sanomat.
The Finnish provider of technology and life-cycle solutions for the marine and energy industries has calculated that an energy system with an emphasis on wind power would reduce the costs of electricity generation by 27 per cent when compared to a system with an emphasis on nuclear power.
“We’re talking about hundreds of millions, if not billions of euros,” Matti Rautkivi, the head of energy solutions at Wärtsilä, was quoted as saying yesterday by Helsingin Sanomat.
Wärtsilä has based its projections on the fact that non-subsidised wind power is already competitive in Finland: the cost of electricity from wind farms, it pointed out, is roughly 30 euros per megawatt hour – only half of the estimated cost of electricity generated by the Hanhikivi Nuclear Power Plant, which is under construction in Pyhäjoki, Ostrobothnia.
The estimate of 60 euros per megawatt hour for nuclear power is considered accurate also globally, according to Rautkivi.
Wärtsilä concluded that the optimal situation would be achieved in Finland in 2030 by increasing market-based wind power generation by 700 per cent and suspending the nuclear power projects in Loviisa and Pyhäjoki. The measures, it highlights in a press release, would decrease the costs and emissions of electricity production by 30 per cent compared to the scenario where the demand is satisfied with new nuclear power plants.
The calculations also indicated that wind power would account for 43 per cent of all electricity production in the optimal circumstances in 2030, bringing the total share of wind and hydro power to 56 per cent.
“It means we’d be well over the EU targets without the bioeconomy,” Rautkivi said according to Helsingin Sanomat.
Wind power accounted for 4.6 per cent and hydro power for 23.6 per cent of electricity generation in Finland in 2016, according to Finnish Energy.
