Alan Ambrose Posted November 26 Share Posted November 26 Original fairly techy and detailed report here: https://ecoblock.berkeley.edu/blog/californias-growing-solar-and-wind-problem/# Summary here: https://www.latimes.com/environment/story/2024-11-24/california-has-so-much-solar-power-that-increasingly-it-goes-to-waste So, will we get the same thing here one day?

SteamyTea Posted November 26 Share Posted November 26 Hopefully. We have about 90 GW of conventional generation in the UK, our current demand is 41 GW, so rather a non story. Link to comment Share on other sites More sharing options...
Mike Posted November 26 Share Posted November 26 From the last story: Gov. Gavin Newsom's advisors and those who manage the state's electric grid say they are working to reduce the curtailments, including by building more industrial-scale battery Storage facilities that soak up the excess solar power during the day and then release it at night. Which is sensible, if overdue. Link to comment Share on other sites More sharing options...
Alan Ambrose Posted November 27 Author Share Posted November 27 (edited) I'm thinking that we're going to end up flipping from E7-like cheap night leccy to cheap day leccy and expensive night time, no? Well, at least in the summer. On Octopus Agile (which is meant to reflect the 1/2 hour market rates) by and large I'm seeing fairly flat rates throughout the day & night except for Octopus's artificial bump between 4 & 7pm.

Well, at least in the summer. You're right - In France that seems likely from next summer. According to the Regulator: To take account of changes in the electricity production mix and the abundance of summer photovoltaic production, stakeholders are being consulted on the gradual adoption of summer afternoon off-peak hours from August 2025" Original in French: https://www.cre.fr/actualites/toute-lactualite/la-cre-consulte-sur-le-futur-tarif-dutilisation-des-reseaux-publics-delectricite-turpe-7-transport-et-distribution-pour-la-periode-2025-2028.html Link to comment Share on other sites More sharing options...

But Energy Can Neither Be Created Nor Destroyed So it will be doing something, somewhere. Link to comment Share on other sites More sharing options...
Alan Ambrose Posted Wednesday at 09:19 Author Share Posted Wednesday at 09:19 Re: Triads. Goodness gracious, the production of leccy is complicated. It’s reassuring to know that it all revolves around tea: Triads typically occur on a Monday to Thursday, during periods of particularly cold weather, at around 5-7pm – when industrial demand and the domestic tea-time period coincide. And it is going to waste if you’re the guy that footed the capital cost for the PV array. Or even the society that conspired to make productive capital available for investment. No?
