National Energy System Operator

Today in The Times, our Chief Operating Officer, Kayte O'Neill and Minal Patel, Global Head of Infrastructure at Schroders Greencoat LLP, outlined how connections reform will overhaul an outdated connections process to give developers and investors the certainty they need to unlock jobs, drive supply chains and supercharge £40 billion per year of economic growth across Great Britain. By moving away from the outdated first come, first served process we can ensure Great Britain gets the energy projects that are needed, when they are needed, where they are needed and are aligned to the UK Government’s energy targets for 2030. The new process will free up space for the technologies that will secure and power our energy system today, while making room for the data centres and electric vehicle superhubs of the future.

As Great Britain progresses toward a more secure, zero-carbon energy future, we’re relying on a wider variety of generation sources than ever before. A main source is sunlight, which can be captured and turned into electricity and heat. Both forms of energy are produced using solar panels, which you’ll see on rooftops of homes and businesses, and in solar farms.  Accurately predicting the amount of electricity that can be generated from solar power is essential for operating the system more efficiently, maximising the potential of this energy source and ultimately lowering costs for consumers. Find out how we’re improving our solar forecasting to deliver savings of up to £30 million a year and £150 million annually by 2035: https://bit.ly/4iDQTSI

Great Britain's electricity sector is going through a period of substantial change, driven by decarbonisation, increased renewable generation, and evolving consumer behaviour. In our draft Energy Forecasting Strategy, you can see how we’ll deliver more accurate, informative, and transparent forecasts to the energy market and how this will support the transformation of Great Britain’s electricity system.

In our first annual Gas Supply Security Assessment, we expect overall gas demand to decline in the years ahead as Great Britain decarbonises, but the amount of gas used on cold days is expected to fall more slowly. Read the assessment to find out more about the availability, reliability and deliverability of gas needed to meet future demands on Great Britain’s National Gas transmission network. Our focus spans the winters of 2030/31 and 2035/36, offering insights into gas supply security over this period.
