In a Twist, Old Coal Plants Help Deliver Renewable Power. Here’s How. Elena Shao 2022 Jul 15 The New York Times www.nytimes.com/2022/07/15/climate/coal-plants-renewable-energy.htmlPrimarily by using the grid connections, including the station transformers. But for some, the land can be used to house a moderate size solar farm. This article, like all too many, incorrectly specifies storage. The units are megawatt-hours of energy, not the megawatts of electricity flow.

Last coal burns at New Mexico’s San Juan station Kevin Clark 2022 Oct 03 Power Engineering www.power-eng.com/coal/last-coal-burns-at-new-mexicos-san-juan-station/“On a clear day you can see forever.” That used to be New Mexico’s advertising slogan and it was true that one could see from Tres Piedras north to Sierra Blanca and south to Sandia crest above Albuquerque; check the distance of a map. But that ended when the power companies began burning coal in the greater Four Corners area. That includes the Navaho Generating Station, the Four Corners Generating Station and the San Juan Generating station. The haze spread over most of southeastern Utah, northeastern Arizona, at least, and northwestern New Mexico, at least down to Albuquerque. Four Corners units 4&5 are only scheduled to shut down in 2031. After that New Mexico can honestly have its advertising slogan back.

[Coal plants] ... scheduled to shut down in 2031. After that New Mexico can honestly [say that on a clear day you can see forever] This sounds good, but the silence on where they get their power from is suspicious. Could it be that the blurb has originated in the PR department of a fossil gas supplier? Gas is a wolf in renewables clothing. Everywhere that a reduction in coal is loudly proclaimed, we should suspect that gas is being quietly increased.

Yes, the San Juan basin still has a considerable supply of gas. However, nothing is being said, so far, about building a nat gas burning electricity generating station. As New Mexico has abundant sunshine and a supply of wind in the “Little Texas” portion of the state, possibly none is thought to be necessary, so far. In any case, a CCGT only takes 4 years to builld so there is plenty of time to schedule one if that is considered necessary.

... nothing is being said, so far, about building a nat gas burning electricity generating station. On the contrary. In your link the operator says "The utility plans to replace San Juan [coal-fired PS] with a mix of natural gas, wind, solar and battery storage". Hah! You and I know what the likely proportions are in that mix. The overwhelming majority of power consumed will have been generated by gas. These guys are professional liars. There is nowhere in the world where an (isolated) grid is powered 100% by solar and wind. Neither can there be, because as any school kid knows, when the wind don't blow and the sun don't shine the grown-ups turn on the power. Power, that is, from a fossil-fired grid, increasingly gas as the coal-fired plants get converted. This sort of PR relies on the public staying in denial, hoping that by praying to wind and gas they will be forgiven for their continuing emissions. However those continuing emissions contribute to a continuing death toll deep into the future. While you and I show any patience with wind and solar, we are allowing the oncoming holocaust to develop. The kiddies won't forgive us.

UK could look to coal to keep lights on this winter 2022 Sep 23 Power Engineering International www.powerengineeringint.com/industry-insights/uk-could-look-to-coal-to-keep-lights-on-this-winter/The metric goes under the odd name of LOLE, loss of load expectation, but refers to an insufficiency of supply, in this study quite a drastic one because of the anticipated lack of hydropower from Norway together with France having difficulty with their older nuclear reactors and of course the general lack of natural gas in Europe. So the UK faces a realistic prospect of rolling blackouts during the very coldest nights. The wind tends not the blow then.

Europe’s largest nuclear reactor enters service in Finland 2023 Apr 16 Phys.org techxplore.com/news/2023-04-europe-largest-nuclear-reactor-finland.htmlThe third EPR to be completed, after 14 years of delays. In my opinion, the EPR is far too complex as, being large, it requires extensive safety features unnecessary for SMRs. But at least it is now available to produce 30% of Finland’s electricity for the next 60+ years.

In my opinion, the EPR is far too complex as, being large, it requires extensive safety features unnecessary for SMRs. But at least it is now available to produce 30% of Finland’s electricity for the next 60+ years. The problem with that opinion is that the Chinese EPRs are just as complex (basically technological clones) yet they were built on time and budget. To me it is obvious that the real problems are in how things are done rather than what. That is where lessons should be learned. Sadly, because that is mostly politically, socially and legally engrained, we are unlikely to learn anything. Indeed; people’s jobs depend on not learning this. Future EPRs built in the West will be plagued by more delays and cost overruns. Heck we will pat ourselves on the back for it. Mark my words.

Europe’s largest nuclear reactor enters service in Finland … … the Chinese EPRs are just as complex … Nope. The Chinese EPRs might be called EPR1 design, modified to have additional, expensive safety features for the Finland EPR, call it EPR2. Then further modified for the EPR under construction in France, say EPR3. The French engineers say it is too complex and have designed what I’ll call EPR4 for further construction, if any.
