The greenhouse gas emissions are half those of coal, gas power plants have low investments costs and they can be operated in a more flexible way, making them suitable to balance out the varying power production from wind and solar energy sources. In total 20 GW of capacity has been notified to the Commission as being under construction, which is about 2% of today's installed total capacity for electricity production (with a further 15 GW of additional capacity notified as in planning).
