1) Introduce a lot of intermittent generation into energy grid without sufficient amount of storage capacity. 2) Use marginal pricing model which effectively guarantees windfall profits for those sources. 3) Utilization of peaking power plants falls, but you still have to keep them because there is not enough storage capacity. 4) Peaking power plants rise generation costs to offset the lower utilization, further adding to the windfall profits. 5) You need more grid capacity to handle energy transfers from distributed generation sources. 5) ???? 6) Act surprised when people loudly complain about electricity bills despite abundant "cheap" generation. Intermittency of generation is an externality (same as CO2 emissions) and should be priced accordingly. People are willing to pay premium for supply stability, but the current pricing model does no account for that. Trying to change consumption habits (like smart grids, dynamic pricing, etc.) works poorly, especially for such vital resource as electricity. I think there should be some kind of price penalty for intermittent sources dependent on total ratio of intermittent generation in the mix. At least until grid-scale energy storage technology will be advanced enough to store approximately week of total energy consumption. | ||||||||||||||||||||||||||||||||||||||||||||||||||

For 5, add in that the new grid capacity is years behind schedule, and the existing grid capacity needs to come offline because it's decrepit, and you also have a policy to connect new sources immediately It leads to a lot of telling new sources to dump their energy, and paying them to dump their energy, while simultaneously paying old gas generators (nearer the demand) to fire up. All for the want of more grid capacity. https://ukerc.ac.uk/news/transmission-network-unavailability... | ||||||||||||||||||||||||||||||||||||||||||||||||||

> Trying to change consumption habits (like smart grids, dynamic pricing, etc.) works poorly, especially for such vital resource as electricity. Why? Has the UK started trying recently? When I lived there nobody gave a hoot about fluctuating prices. It would have been hard to even know when electricity was expensive or not. Has it changed? Meanwhile >three decades ago my grandparents in rural France had a big red lamp on the kitchen wall that would light up when energy was expensive. It was a part of their life and they had no problem with it. They chose that plan deliberately because it ended up cheaper. If you’re saying that even with adaptive behavior , it’s all a wash because the constant cost of peakers is so high that you lose all savings when they kick in , no matter how little you use; ok, I believe you did the math. But if the claim is “it’s impossible for humans to adapt their energy consumption depending on the current price of electricity”, I have seen first hand that is not true. For sure when I lived in Britain nobody did this at all, but that would be at best a British limitation, not a human one. | ||||||||||||||||||||||||||||||||||||||||||||||||||

This is addressed by the capacity market mechanism. | ||||||||||||||||||||||||||||||||||||||||||||||||||

Intermittency is already handled by the price mechanisms, they are set quarter-hourly; if you’re not available when there is high demand you don’t get paid. The marginal price windfalls happen specifically when you’re able to deliver at a low cost when demand is high in the same ISP. This just seems like data-free fear mongering. | ||||||||||||||||||||||||||||||||||||||||||||||||||
