October 25, 20242 yr See: https://www.theguardian.com/environment/2024/oct/24/power-grid-battery-capacity-growth This sounds good, but what are the implications: No point in having house-based batteries as the grid does it cheaper? Renewables + batteries as good as nuclear etc? More transmission capacity required?
October 25, 20242 yr Batteries don't generate power. They help smooth the peaks and troughs of usage demand and match it to also variable renewable generation. No more no less. so they will be an essential part of a more renewable generation.
October 25, 20242 yr I find it very funny all these people working out ROI on PV and Battery on export at 15p when in 12-24 months we’ll be the same as California and you’ll be at -15p. this will move really quickly so be very certain on your ROI re renewables.
October 26, 20242 yr Why do they not mention the storage capacity in the article. It is all very well having x amount of GW, but for how long. Edited October 26, 20242 yr by SteamyTea

October 26, 20242 yr Author OK so: Kimberly is a journalist/lawyer Mark is a thought leader with degrees in geography and history Here’s the source: https://www.eia.gov/todayinenergy/detail.php?id=63025 Actually maybe that way of reporting capacity is somehow standard for some reason? https://www.energy.ca.gov/data-reports/energy-almanac/california-electricity-data/california-energy-storage-system-survey#:~:text=From 2018 to 2024%2C battery,by the end of 2024. For baby batteries, I know the generation/current is often specified in ‘C’ with C being the capacity and often around 1 see e.g. https://www.power-sonic.com/blog/what-is-a-battery-c-rating/ Edited October 26, 20242 yr by Alan Ambrose

I was chatting to vicar and had a thought. 'when does a cult become a religion?' The stock reply of 'when you get 1 million followers' came out. That was not good enough for me.

October 26, 20242 yr Author >>> Without checking I think it is for coulomb Yes it is, but in another context it's also the battery charge/discharge rate (which may be different). So, a 10 Ah battery which has a 1C charge rate and 2C discharge rate will charge ~10A in 1 hour and discharge at ~20A in 0.5 hour.
