We could see up to 30 new gas-fired power stations running in Britain by 2030 under an expansion of generation plans revealed later this week. A gas strategy from the Department of Energy and Climate Change is expected to suggest an additional 26gigawatts (GW) of new gas capacity is required (up to 30 new plants) by 2030, the Telegraph has reported. It will also reveal a scenario in which 37GW of gas plants could be constructed in Britain, meaning gas could account for almost 50% of the energy mix by 2030. The increase in gas capacity would involve changing carbon emissions plans confirmed last year. However, the Chancellor has said he doesn't want to see Britain progressing faster than the rest of Europe when it comes to lowering emissions.
