The pace of change in the GB power market shows no signs of slowing. With renewable deployment continuing to expand and electrification driving new sources of demand across heat, transport and data infrastructure, the market context for renewable assets is becoming increasingly complex to navigate.
Revenue projections that made sense twelve months ago may look quite different today. Wholesale price dynamics, capture rate pressures and route-to-market considerations are all shifting, and for organisations with projects in development or investment decisions approaching, having a clear and well-evidenced long-term view has never mattered more.
Our Renewables and Power Market Forecast service is designed to provide exactly that.
To support your planning, we would like to offer you a complimentary overview of our latest Q1 2026 quarterly forecast, which includes:
- Where prices are going: How wholesale electricity prices are expected to evolve to 2050, including the near-term impact of falling gas prices and renewables build-out, and the longer-term influence of demand growth from electrification, data centres and industry
- Key drivers: The role of gas prices, carbon costs, new LNG supply and generation build-out in shaping the price outlook
- Market conditions: How evolving conditions may affect revenues for offshore wind, onshore wind, solar and co-located assets
- Value: How the sources of value within the GB power market are changing, and what that means for project economics and investment cases over a 35-year horizon
Request your complimentary overview below and explore the themes shaping the long-term future of the GB power market.
