Conventional power stations can take hours to synchronize with a utility grid, and start supplying energy. But those power stations can instantly trip without warning, and stay offline while engineers determine the cause. Balancing grid supply and customer demand is a priority for control center operators. But their task becomes a little easier when they have a mega battery backup on standby.
Load Balancing and The Role of Mega Battery Backup
Grid operators can quite accurately predict their gross customer demand going forward, based on historic trends. They traditionally use power stations to deliver their base load requirements, and plug in peaking stations during high demand. But that was before the exponential growth in battery storage.
Storage batteries added a new dimension, as savvy customers learned to charge their batteries when demand was low. And then sell the energy back at a higher rate during peak demand. Renewable energy took that model forward, to the point where every utility has at least one mega battery backup.
Batteries Win the Day After Power Link Fails
The United Kingdom national grid relies on a 1.4 gigawatt line from Norway to supplement its own power generation. That’s sufficient electricity to power three quarter million homes, or a town the size of Oklahoma City.
On October 8, 2024 the Norwegian undersea cable went from ‘hero to zero’ in the flash of a second. In past times this might have affected power stability, but not this time! This time the UK had a mega battery backup on standby.
Website 10 Energy Mix describes how a UK battery energy storage system synchronized online within two minutes, restabilized the grid, and averted a potential crisis. These comforting incidents are becoming so common, that major news channels hardly mentioned the incident.
