Course notes on Introduction to Electricity Markets: www.e-education.psu.edu/ebf483/node/508Chapters 8 & 9 give the essences of the 4 markets. Note that ERCOT does not have a capacity market and so is called energy only although of course ERCOT has an ancillary services market.

Electricity Pricing Breakdown: Ancillary Services Cost Components (Article 4 of 5) 2014 Jan 20 Engie www.engieresources.com/electricity-pricing-breakdown-ancillary-services-cost-components-(article-4-of-5)First notice the price pyramid. The least amount is for transmission, next for ancillary services. ERCOT doesn't have a capacity market, which is much simpler to administer. Next note all the detailed components which go into stabilizing a grid, with then the pricing fairly determined, partially "by the market". I believe that the largest components are for up regulation, i.e., more power, and down regulation, also difficult for some types of generators to accomplish quickly. However, the reserve component is supposed to be around 13% of generation so there's a hefty payment to the generators in reserve status. Then there are all the mini parts of grid stability.

PJM’s ‘focused’ MOPR boosting renewables and nuclear as FERC commissioners deadlock Ethan Howland Utility Dive www.utilitydive.com/news/pjm-focused-mopr-takes-effect-ferc-capacity-market/607417/Wishing you the very best in understanding this! It, once again, illustrates the difficulty in establishing a ‘fair’ capacity market: nobody can agree upon just what ‘fair’ is supposed to mean in concrete, dollar and cents, terms. So ERCOT abandons a capacity market. The nuclear power plants do fine, losing money most of the year but making it back, and more, in the few weeks of the runup in prices over the summer. The problem in Texas last winter was it was so cold the natural gas system froze. Not clear a capacity market would have solved that problem. See the ERCOT Texas thread.

Why electricity prices should not be left to bogus ‘free markets’ Prabir Purkasayastha 2022 Sep 16 AlterNet www.alternet.org/2022/09/electricity-prices-bogus-free-markets/?traffic_source=ConnatixLower cost producers receive the same price as the most expensive generator actually used. So, the argument goes, they are overpaid, receiving ‘unfair’ profits. I am sure that the neoliberals of the Milton Freeman school have a counter-argument, but I don’t know it off-hand.
