Serbia’s biggest coal-fired power plant complex, which accounts for half the country’s electricity generation, will boost output in 2010 to 20.1 billion kilowatt-hours from 19.5 kWh in 2009, an official said. Upgrades over the past 10 years to increase capacity are now paying off and allowing officials at the three state-run plants some 40 kilometers from Belgrade to plan for higher production in 2010, Djordji Biljanovski, deputy manager of the three-plant complex told Reuters.
