Re: Wow
Wind and solar are not cheaper by any objective metric.
LCOE ignores grid expenses - including massive transmission buildout connecting wind and solar farms, backup costs for when wind/solar are not working, storage costs for when there is excess wind/solar vs demand or curtailment costs to turn wind/solar off.
Let's look at these one by one.
Transmission: people think moving power by electricity is cheap - in fact, it is 10x or more expensive to move power via electricity, than via pipelines and even land/sea tankers. This is because there are massive capital and operating costs associated with power transmission. Yes, road and port costs are subsidized, but that's because roads and ports move lots of things besides power whereas transmission lines do nothing but move power.
Backup costs: it isn't just daytime/night-time for solar or wind/no wind. It is now well documented that entire regions - as in the entire EU for example - can see 30%+ variation on an annual scale for wind and/or solar on an annual basis. Between that, the shorter time scale seasonal/monthly/weekly/daily/hourly intermittency - this forces overbuild of name plate capacity. This overcapacity started at 200% vs. comparable dispatchable (ie non intermittent) forms of electricity generation but is rapidly scaling to 400% to 500%. Which in turn leads to...
Storage or curtailment costs: Storage via pumped hydro can work, but there is massive opposition to this from enviro groups. Batteries are horrifically expensive at grid scale plus there are real questions on just how much lithium or other materials are available, should grid scale storage be attempted. And I don't mean 1 facility, I mean grid scale storage that can compensate for the seasonal/monthy/weekly/daily variation plus the 30%+ annual potential variation. Most battery storage now is focused on moving midday solar production to the evening duck curve spike ie 4 hours.
And clearly storage isn't working. The UK just hit 10.2 terawatt-hours of curtailment just for wind generation in 2025. This breaks the 2024 record of 8.3 terawatt-hours of curtailment set in 2024, which in turn broke the record of 4.3 terawatt-hours of curtailment set in 2023. Each of these years, this curtailment cost over 300 million GBP. See a pattern yet? To put these numbers in context: The UK consumes, overall, 260 to 320 terawatt-hours of electricity. So 2025 wind curtailment was over 3% of all of the electricity consumed in that nation over an entire year!
Nor is the problem just in the UK. Grid Strategies tracks congestion = curtailment across all 6 major US subgrids. The overall congestion cost was slightly under $4 billion in 2016 but over $8 billion in 2023 - with both prior years being higher than 2023.
Net net: LCOE is bullshit. Wind and solar have their place, but not as "cheapest power" and most certainly not as baseload power.
