Wind power is blowing gas and coal-fired turbines out of business in the Nordic countries, and the effects will be felt across the Baltic region as the renewable glut erodes utility margins for thermal power stations. Fossil power plants in Finland and Denmark act as swing-producers, helping to meet demand when hydropower production in Norway and Sweden falls due to dry weather. The arrival of wind power on a large scale has made this role less relevant and has pushed electricity prices down, eroding profitability of fossil power stations. Demand for coal condensing power in the Nordic power market has decreased as a result of the economic recession and the drop in the wholesale price for electricity," state-controlled Finnish utility Fortum said. Nordic wholesale forward power prices have almost halved since 2010 to little over 30 euros per megawatt-hour (MWh) as capacity increases while demand stalls on the back of stagnant populations, low economic growth and lower energy use due to improved efficiency. "The Nordic system price will likely more often clear well below the production cost for coal fired power production," said Marius Holm Rennesund Oslo-based consultancy THEMA. "This will, in our view, result in mothballing of 2,000 MW of coal condensing capacity in Denmark and Finland towards 2030," he added. Adding further wind power capacity at current market conditions could lead to power prices dropping towards as low as 20 euros per MWh, the marginal cost for nuclear reactors, Rennesund said.
