PRAGUE, Oct 20 (Reuters) - The Czech government moved to counter the threat of soaring electricity prices caused by a solar energy boom on Wednesday with new taxes that will limit the price rise to 5.5 percent next year.
Generous tariffs that obliged distributors to buy solar power at a higher price was expected to lift electricity prices as much as 20 percent next year after subsidies prompted investors to pile money into solar plants.
But the investment boom risked overloading the grid, while spiking prices could hit the fragile economic recovery.
The government approved a 26 percent tax on solar plants larger than 30 kilowatts installed capacity and connected to the grid in 2009 and 2010, and imposed a windfall tax on CO2 credits allocated to electricity producers in 2011 and 2012.
Prime Minister Petr Necas said the measures should bring government coffers 4.2 billion crowns and 4.8 billion crowns, respectively. The money would then be used to compensate distributors for paying feed-in tariffs to solar plants.
"For end customers, for both households and for the industrial sphere, the (electricity) price hike will be a maximum of 5.5 percent next year," Necas said.
High feed-in tariffs, guaranteed by the government for 20 years, helped the central European state become the third biggest solar nation in Europe in terms of new capacity.
CORRECTING A WRONG
Analysts said the taxes were meant to rectify a policy in which subsidies granted to solar power producers had grown too large after a steep fall in the price of solar power cells -- adding the move was not like a windfall tax on utilities in Hungary that the government is using to plug budget holes.
The Czech measures, especially the tax on CO2 credit, will hurt majority state-owned power group CEZ <
>, the country's biggest power producer whose shares dropped to a 1-1/2 year low this month. Shares on Wednesday fell more than 1 percent to 775 percent after the tax announcement.Ceska Sporitelna analyst Petr Bartek said the tax for 2011 and 2012 knocks 12 crowns per share off CEZ, but added the government may be over-pricing the costs of the solar subsidies.
"Emission allowances are obviously the easiest target, also because they will not have to give 30 percent to minority shareholders," Bartek said, referring to dividend payments.
"Unfortunately, it comes at a time, when CEZ needs to invest a lot, so it is not an especially favourable situation."
Necas said another source of money in coming years should come from auctioning CO2 credits in the years 2013-2020, instead of giving them to electricity companies for free as originally planned.
The value of these credits is estimated at some 40 billion crowns and buying them instead of receiving them for free could mean an extra cost of more than 30 billion crowns for CEZ.
CEZ profitability is key to the government which plans to use CEZ dividend as a cushion for partially privatising the country's overly redistributive pension system.
