The UK's electricity system operator is exploring plans to financially incentivize households to use more power during periods of exceptionally high renewable energy generation. The initiative, part of a broader Demand Flexibility Service, aims to help balance the national grid by shifting consumption to times when wind and solar output is plentiful, rather than curtailing (wasting) that clean energy.
National Grid ESO has run similar short-term schemes in recent winters, paying consumers to reduce usage during peak demand. The new proposal, highlighted in its 2024 'Beyond 2030' report, considers the opposite: encouraging increased consumption during potential summer surpluses of renewable power. This could involve smart tariffs or direct payments for using electricity at specific times.
The move addresses a growing challenge of grid management as Britain's renewable capacity expands. In 2023, renewables provided a record 47.3% of the UK's electricity. Periods of low demand coupled with high wind and solar generation can lead to negative electricity prices and the need to pay wind farms to switch off. Shifting demand to these times can improve grid efficiency and reduce overall system costs.
Any new scheme would be voluntary and rely on smart meter technology. Experts note that while it could lower bills for participants and reduce carbon emissions by maximizing green energy use, its widespread impact depends on consumer uptake and the development of more flexible, large-scale electricity demand, such as for electric vehicles and heat pumps.
