Grid batteries make sense for those 30 second to 30 minute outages but it seems unlikely that they would be viable for those 2 week cloudy windless spells we get.
My understanding is the UK plans to fill that gap with peaker gas plants with CCS. They are being contracted for a maximum of two weeks in the year.
- ben_w 2y agoCurrently sure, hence the numbers I gave. Theoretically possible already, but the UK isn't buying 30% of global supply for the next decade. Forecasts suggest supply will rise to the level where this is doable… but over the next decade or so of increasing global manufacturing capacity. Considering what happened to global and local trade in the last decade, I'm not confident beyond 5 years, and even then only somewhat confident.
- youngtaff 2y agoThere's a weakness in the way the National Grid works which means we don't fully utilise the battery capacity that's available But in California batteries supply 20% of the power in the evening https://archive.is/IruIQ https://archive.is/IruIQ
- tonyedgecombe 2y agoI'm not saying we shouldn't use batteries, rather that they don't solve every problem. In particular they probably won't ever be suitable for week long outages.
