As the UK continues to grow its renewable capacity, one challenge becomes increasingly clear: how to store energy when the sun isn’t shining or the wind isn’t blowing. The latest grid operator reports urge a dramatic increase in both solar and storage capacity by 2030 — and that spells opportunity.
Storage: The Missing Link in Renewable Growth
To achieve the UK’s clean energy goals, the grid will need far more than just generation — it needs energy storage. The National Electricity System Operator (NESO) recommends multiplying battery capacity from 5 GW today to 23–27 GW by 2030. That’s where technologies like BESS (Battery Energy Storage Systems) and long-duration storage become essential.
Storage Enables More Solar
Solar generation peaks during daylight — but energy demand peaks during evenings. Without storage, much of that solar energy can go unused. Storage systems:
-
Stabilise grid frequency.
-
Reduce curtailment of renewable generation.
-
Create new revenue streams via arbitrage and grid services.
Beyond Batteries: Pumped Hydro and Innovative Technologies
The UK isn’t just planning batteries — large scale pumped storage projects like the proposed Earba scheme in Scotland could offer up to 40 GWh of grid-scale storage capacity, a game changer for seasonal and long-duration storage.
Emerging technologies like liquid air energy storage (LAES) — developed by British innovator Highview Power — are gaining investment and could complement batteries for extended backup and grid flexibility.
