The Intermittency Report
An Assessment of the Evidence on the costs and impacts of intermittent generation on the British electricity network.
UKERC's report represents a definitive picture of the costs and impacts of intermittent energy supplied by renewable sources, such as wind. Some commentators have suggested that renewable energy is made much more costly, or is drastically limited by intermittency. The report finds that these views are out of step with the vast majority of international expert analysis and that intermittency need not present a significant obstacle to the development of renewable sources.
