* Decision would help CEZ
* Carbon credit auction to help fund solar costs

PRAGUE, Nov 25 (Reuters) - The Czech Industry Ministry opposes a proposal to reduce the allocation of free CO2 credits to industry in 2013, a deputy minister said on Thursday, which could benefit state-controlled utility CEZ <
>.Under the current plan, companies are due to get 70 percent of available credits for free in 2013, and 30 percent will be auctioned off. The proportion of auctioned credits is due to rise to 100 percent in 2020.
But the government is considering a proposal to increase from 2013 the percentage of credits that are auctioned in order to raise money to offset a rise in electricity prices coming from the expansion of solar power plants, which sell electricity to the grid for high regulated prices.
Deputy Industry Minister Tomas Huner told Reuters on the sidelines of an oil conference, however, that the ministry was against changing that allocation in 2013.
"We would like to solve (the solar issue) from other resources," Huner said.
"We want 70 percent given for free and the other 30 percent auctioned off in 2013, and gradual transition to 100 percent auctioning (in 2020)."
Earlier in November the Czech Republic halved feed-in tariffs for solar plants opening from 2011 and approved new solar and carbon taxes to deal with a solar boom, which threatens to send home and business power prices soaring.
Parliament pushed through a 26 percent tax on solar power revenue and another tax charging generators 32 percent of the value of carbon emissions permits granted to them -- originally for free -- in 2011 and 2012 to raise funds to cap power hikes at 5.5 percent. The solar plant tax is for three years.
The new tax on the credits given to electricity generators as part of an EU scheme to limit emissions of greenhouse gases and combat climate change would mainly burden majority state-owned CEZ, central Europe's biggest power producer.
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 due to an investment boom sparked by generous feed-in tariffs.
In 2010, installations have accelerated ahead of cuts in the feed-in tariffs. By Nov. 8, the installed capacity was 1,034 megawatts, and energy regulator ERU estimated the number could hit 1,700 MW by the end of the year.
If this happens, the government plans to tap state coffers to keep power price increases in line.
