The UK lost 11.4GW of coal and gas generation capacity in the three years to end of 2015, latest government data shows.
Some 8.8GW of coal-fired plant came off the transmission system, alongside 2.6GW of gas.
However, over the same period, around 3.5GW of renewable generation was connected to the transmission system (almost 1GW of onshore wind, around 1.3GW offshore wind and 1.25GW of bioenergy).
Meanwhile, over 10.3GW of net new capacity was installed on the distribution network: some 2.3GW of onshore wind; around 0.8GW of offshore wind; 0.8GW of bioenergy and a 7.4GW surge of solar PV since end of 2012.
According to the DUKES figures, total UK solar PV capacity at the end of 2015 stood at 9.2GW, an increase of 3.8GW, or 69%, on 2014.
While cuts to subsidies have pared back subsequent PV growth rates, National Grid predicts solar PV capacity will hit 12GW by next summer, requiring greater system flexibility.
DUKES data confirms that there are now more than 800,000 solar PV installations in the UK, which suggests a significant opportunity for battery storage growth should prices continue to fall in line with estimates.
