The UK electricity system is among the world's most advanced, evolving from a reliance on large coal, gas, and nuclear plants, which were straightforward to control and respond to national demand.

​

As traditional plants are phased out, thousands of decentralised generators are reshaping electricity flows. The National Grid ESO collaborates with the energy sector to innovate and adapt, ensuring reliable electricity supply across the country.

With the UK's shift to net-zero carbon emissions, there’s a growing demand for renewable and stable power solutions. This transition from base-load fossil fuels to flexible gas and renewables like wind and solar brings challenges, including instability from variable energy sources.

To address this, the UK is investing in small, flexible power plants that provide stable, low-emission electricity when needed. This dynamic market for small-scale generation and storage supports the regulatory framework, balances the national grid, and offers reduced risk for investors.
