"Dozens of British wind farms run by some of Europe’s largest energy companies have routinely overestimated how much power they’ll produce, adding millions of pounds a year to consumers’ electricity bills, according to market records and interviews with power traders.
These extra costs are linked to a growing problem with Britain’s outdated electricity network: On blustery days, too much wind power risks overloading the system, and the grid operator must respond by paying some firms not to generate. This “curtailment” costs consumers hundreds of millions of pounds each year.

Adding to that expense, some wind farm operators exaggerate how much energy they say they intend to produce, which boosts the payments they receive for turning off, according to nine people — traders, academics and market experts — most of whom agreed to discuss this controversial behavior only on condition of anonymity.
In effect, they said, the grid has paid some wind farms not to generate power that they wouldn’t have produced anyway."
