The Topic
The UK is testing ways to use more electricity when wind and solar generation is high, including discounted tariffs, demand-response programs and incentives for households and businesses to shift flexible activities. The measures aim to reduce renewable curtailment and make better use of existing generation as grid constraints and slower growth in electricity demand create surplus periods. Related reporting highlights plug-in solar, batteries and daytime cooling as household applications of the same principle: aligning consumption with when renewable power is available.

Summary
- NESO and energy suppliers are encouraging households and businesses to move flexible electricity use into windy or sunny periods.
- The UK is trialling discounted or rewarded electricity during periods of high renewable output.
- Grid constraints are leaving substantial Scottish and wider UK wind generation unused, increasing curtailment costs.
- Plug-in solar could broaden access for flats, renters and homes with unsuitable roofs, but output depends heavily on placement and sunlight.
- Small batteries and time-of-use tariffs can improve solar savings by shifting daytime or off-peak electricity into higher-demand periods.
- Solar generation can offset daytime air-conditioning demand, although evening cooling generally still requires grid electricity or storage.
History
The story is largely stable, but the framing has shifted slightly toward broader household applications of flexible demand, especially daytime cooling, alongside existing tariff and demand-response trials. The new version also emphasizes Scotland and wider UK grid constraints a bit more directly as the reason surplus renewable power is going unused.
The story has shifted from mainly household solar adoption and grid constraints to a broader demand-flexibility strategy centered on matching electricity use to periods of abundant wind and solar. It now emphasizes active trials by NESO and suppliers, plus industrial and transport electrification, as the main route to reducing curtailment.
