UK wind farms played a major role in reducing electricity prices in 2025, according to new analysis from the Energy and Climate Intelligence Unit (ECIU). The findings underline the growing importance of renewable wind energy and the role of companies such as CWP Energy, in delivering more affordable, secure, and sustainable power for the UK.
As a UK-based renewable energy company specialising in the development and operation of wind farms, CWP Energy is part of the expanding wind sector that is helping to cut wholesale electricity prices, reduce reliance on imported gas, and support the transition to a net zero energy system.
The ECIU’s analysis shows that average day-ahead electricity prices in 2025 were around £83 per megawatt-hour (MWh). Without wind generation, prices could have reached £121 per MWh. This means wind power reduced wholesale electricity prices by around £38 per MWh, representing a 31% reduction compared with a system without wind farms.
These savings build on similar effects seen in 2024, when wind generation reduced prices by approximately 25%. The trend reflects the growing influence of wind energy across Britain’s power system, driven by sustained investment from renewable developers such as CWP Energy.
Britain currently has more than 29 gigawatts (GW) of operational wind capacity, with almost another 10 GW under construction. This expanding fleet of wind farms increasingly displaces gas-fired power plants, reducing the role of gas in setting wholesale electricity prices.
CWP Energy contributes to this national capacity by developing and operating wind farm projects that deliver long-term, homegrown renewable power directly into the UK electricity system. By investing in wind infrastructure, helping stabilise energy prices, improve energy security, and protect consumers and businesses from volatile fossil fuel markets.
ECIU Energy Analyst Jess Ralston highlighted that increasing renewable generation supplies “homegrown energy” while suppressing prices by reducing dependence on imported gas. This is a core objective shared by CWP Energy, whose wind projects are designed to deliver clean, reliable electricity while supporting the UK’s climate and energy security goals.
As the UK continues to expand its renewable energy capacity, CWP Energy remains committed to playing a key role in building a resilient, affordable, and low-carbon power system.
