The trade association for the energy industry described today's Energy Bill as a "positive step forward" but called for more detail to give investors clarity and confidence over the direction the UK is taking on energy policy.
Angela Knight, Chief Executive of Energy UK, said: "The capacity market proposals will mean that gas power stations will be there, not just to keep the lights on while the new nuclear power stations and renewables are being built, but also for the longer term future.
"This means that the huge investment will now start being made in our energy infrastructure and this will create jobs and help economic recovery. At the same time, a focus on affordability for households and for businesses of all sizes, now and during these changes, is essential."
It is the Government's long awaited light bulb moment. The Energy Bill published today envisages changes that would reach into our lives.
By 2020 we will be paying nearly £100 a year more for energy. But whether bills will come down again afterwards is still in dispute.
The coalition will announce plans on updating the energy infrastructure of pylons and power stations, and cutting our reliance on carbon.
