The UK's new power projects will start producing electricity within the next 12 months, suggesting the need to replace its ageing coal-fired and nuclear power plants over the next decade.
The new capacities being built are either gas or wind power plants aimed to curb carbon emissions from coal-fired plants.
About seven new power plants will start commercial operations between 2010-2011, according to Reuters.
The projects are Dong Energy's 824MW Severn Power plant, SSE and RWE's 500MW Greater Gabbard wind farm, Scottish Power's 120MW Arecleoch onshore wind farm, and RWE npower's 1,650MW Staythorpe combined-cycle gas turbine.
E.ON UK's 1,260MW Isle of Grain power plant, DONG Energy and Scottish and Southern Energy's 367.2MW Walney offshore wind farm and EDF Energy's 1,300MW CCGT power plant are also included.
