This from Bloomberg (01/02/24) highlighting the practice of wind power companies overstating how much power they will generate.

UK Regulator probes wind power overstatement. The probe followed a report that many wind farms have saddled consumers with millions in extra costs by overestimating the energy they planned to generate. The UK energy regulator Ofgem is investigating the behaviour of wind farms that have been overstating how much power they will produce. The probe follows a Bloomberg News report earlier Thursday which found that dozens of wind farms, many run by some of Europe’s largest energy companies, have saddled consumers with millions in extra costs by routinely overestimating the energy they planned to generate. “Ofgem’s wholesale markets oversight team are investigating the alleged behaviour,” a spokesman said in an emailed statement, adding that the regulator had also asked National Grid Plc’s network operator to look into the matter. Bloomberg analysed 30 million records from 2018 through to June 2023 to compare wind operators’ daily forecasts of the energy they planned to generate to their actual production when they weren’t curtailed. Out of 121 wind farms in the analysis, 40 overstated their output by 10% or more on average, and 27 of those overestimated by at least 20%.

What this seems to mean is that, by overstating what they might have produced had they not been constrained wind power stations get more from the constraint payments. Is there anything about big wind that isn’t crooked?
