Impossible to know if Hinkley plant will be good value

It is a stark fact that over the next decade, old coal-fired power stations and nuclear reactors that generate about 60 percent of the nation's electricity are going to be shut off as they reach the end of their useful lives.

We desperately need to be investing in new ways of generating power, and the new Hinkley power station will provide about seven percent of the overall requirement.

Nuclear is relatively clean, but it is extremely expensive to build, so whether this turns out to be good or bad for consumers is very difficult to tell.

We simply don't know where energy prices for other sources are going to be in 10 years' time when this power station comes onto the grid.
