The world’s biggest developer of offshore wind farms issued a reality check to the industry, saying it has overestimated the amount of time its turbines are generating electricity.

Copenhagen-based Orsted A/S announced that offshore wind farms wouldn’t produce quite as much power as previously forecast. The adjustment could shave millions of dollars of revenue a year off each project. It’s also a warning to other developers who may have used similar analysis to estimate the economics of their projects.
