Market Growth Factors

The market for clean energy generated in the UK is increasing due to various government schemes/plans and the development of new technologies. The market size was 163.8 TWh in 2025 and is expected to grow at a CAGR of 6.95% to be 299.8 TWh by 2034. Government policies toward encouraging new renewable capacity and decarbonization targets are the main growth drivers.

Developing the offshore wind market, particularly to meet 2030 capacity in the UK where the country is a world leader, is an important area, and turbine development, as well as capital cost reductions have spurred private sector investment. The Dogger Bank Wind Farm will be the largest in the world when completed, generating enough power for around 6 million homes each year, supporting decarbonization and jobs.

Solar PV is being deployed rapidly, in part due to rapidly falling prices of PV with nearly 190,000 residential rooftop solar PV installations completed in 2023. The government pays or feeds back energy to the grid for small power producers. Solar installations are driven by the need for grid stability and the economics of large solar farms and energy storage technologies (notably lithium-ion batteries).
