British senior government officials said that if prime minister Theresa, (Theresa May) had to stop to invest 20 billion pounds of hinckley Angle (Hinkley Point) nuclear power plant project, Britain's energy security and carbon emissions reduction targets will be at risk.

On Monday, participated in 2013 with the French state-owned energy group, electricite DE France (EDF) agreements to the construction of the UK since the 1990 s, the first new nuclear plants, senior officials said they still think the project value, and despite the criticism of the project causing high costs to consumers more and more.

They told a parliamentary committee, to 2025 hinckley Angle installed capacity of 3200 megawatts - is expected to meet about 7% of British electricity demand - that for reducing carbon emissions of security is crucial to Britain's electricity demand, at the same time.

Mrs May ordered a retrial of hinkley shortly after she became prime minister last year, but eventually released the project in September.

However, Mrs May's decision has been increasingly scrutinised by the delays and cost overruns of similar French reactors in other countries.

At the same time, the cost of alternative sources of low-carbon energy is reduced.

Last month, according to the latest contract, offshore wind power 15 years guarantee of the price of 57.50 pounds per megawatt hour - far below the EDF for hinckley Angle project promised the price of 92.50 pounds per megawatt hour 35 years.

But the business strategy of energy and industry (BEIS) general secretary Alex Chisholm (Alex Chisholm) said on Monday, this is not the same type of comparison, because nuclear power plant than intermittent wind turbines more reliable.

Mr Chisholm and other civil servants are required to provide evidence to the Commons Public Accounts Committee.

Earlier, the National Audit Office (the National Audit Office) criticized, called the hinckley Angle a "risky and costly projects," and said that all cabinet ministers failed to consider for the plant with lower cost financing way.

Was responsible for negotiations with the French electricity standing in front of the British energy secretary Stephen's grove (Stephen Lovegrove) said that this is a "at the time of the policy limit great agreement".

Rove grove, recalls David Cameron (David Cameron's coalition government ruled out with taxpayers' money Angle of hinckley investment project, because the government pay attention to reduce public debt, and the Liberal free Democratic Party (Liberal Democrats) holds objections.

This led to an agreement between edf and CGN, China's state-owned nuclear power company, to agree to cover the full cost of the project.
