Preparing for a net zero power system (SIF)

A key policy commitment within the UK government’s net zero strategy is to fully decarbonise the power system by 2035, subject to security of supply considerations11. This has made Great Britain the fastest decarbonising power system in the world. As of 2020, around 40% of installed capacity and 30% of generation output came from fossil fuels, these may need to be replaced by renewables, nuclear and other low carbon sources prior to 2030. Particularly, significant increases in deployment of offshore wind (supported by a policy commitment of 50 GW by 203012), onshore wind, and solar PV (five-fold increase by 2035) are expected.
