As highlighted in Challenge for Wind Power Can be Reaching Customers, wind generators can be forced to curtail their output in the name of maintaining grid reliability. Director of US programs Rich Sedano, describes the challenges faced by ISO New England and renewables developers as the “growing pains of an adolescent industry.” ISO-New England, tasked with keeping the lights on, is taking the role of a “cautious adult.” In What Lies Beyond Capacity Markets, RAP proposes long-term solutions to maintaining reliability—through the industry’s adolescence and into adulthood—including properly valuing demand side resources and paying electricity generators according to their ability to quickly ramp up and down to balance intermittent renewable resources. Increasing the grid’s ability to flex in response to the variable output of wind generators will also reduce the amount of curtailment wind generators face.
