This report sets out scenarios for the UK power sector in 2030 as an input to the Committee’s advice on the fifth carbon budget. The Commission on Climate Change ( CCC ) has published a report which sets out scenarios for the UK power sector in 2030 , based on the advice it presented to the government on the fifth carbon budget . The scenarios provide a tool for the CCC to show that their advice is competitive , affordable , and promotes energy security , whilst ensuring that the UK 's statutory 2050 emissions target can be met . The report says that by the 2020s low - carbon sources of energy generation will become cost competitive with new gas - fired generation , adding pressure on the government to clarify controversial spending cuts in its clean energy budget . Over the next 15 years , the UK will need to add up to 200TWh of new power generation capacity to replace retiring coal or nuclear plants .
