PRAGUE, Oct 20 (Reuters) - The Czech government has approved measures to limit a rise in 2011 power prices for both companies and households to a maximum of 5.5 percent, Czech Prime Minister Petr Necas said on Wednesday.
The government has been under pressure amid a regional and senate elections the past and the next weekend, to produce a plan to prevent an electricity price hike caused by an overly generous solar subsidies introduced by the previous political administration.
The high feed-in tariffs, guaranteed by the government, made power production from solar plants a highly profitable business and the Czech Republic, a country of 10.5 million people, was the third-biggest solar nation in Europe last year in terms of new installed capacity.
"For end customers, for both households and for the industrial sphere, the price hike will be a maximum of 5.5 percent next year," Necas said.
Curbing the price hike was possible thanks to simultaneously implementing several measures, including a 26 percent tax on solar plants connected to the grid in 2009 and 2010.
This is expected to bring to the state coffers some 4.2 billion crowns, Necas said.
The government also agreed to impose a windfall tax on CO2 credit allocated to electricity producers only, in years 2011 and 2012. This is expected to earn the state 4.8 billion crowns, Necas said.
Unlike windfall taxes on utilities and other sectors in Hungary, meant to help plug holes in budget revenues, analysts said this tax was 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.
The government will decide about the tax rate later, depending on how many companies will be affected by this, he said.
Another source of money to limit power price increases in coming years should come from auctioning CO2 credits in the years 2013-2020, instead of giving them companies for free as originally planned, the prime minister added.
The value of these credits is estimated at some 40 billion Czech crowns and buying them instead of receiving them for free will mean an extra cost of more than 30 billion crowns for majority state-owned power group CEZ <
