Advancements in forecasting have improved the reliability of day-ahead and hour-ahead estimates of wind generation. Wind never will behave like a base-load power plant. But as system operators...
Plunging Wind Into the Grid
renewable power. It also can provide the incentives and investment signals for siting new transmission lines so that other intermittent renewables, such as solar energy, will be better able to participate in competitive wholesale markets. The program is helping establish standard protocols integrating wind seamlessly and economically into the national transmission grid, giving Americans access to a clean energy resource that has an unlimited supply of fuel.
PJM Pushes Wind Energy 'First'
In an effort to boost wind energy in its service territory, PJM Interconnection in late April said it would offer capacity credits to wind generators for the first time.
The new rule, approved by PJM's Reliability Assurance Agreement Reliability Committee, takes effect June 1.
PJM said the credits would be based on a wind-turbine facility's actual performance. "The credit is a three-year rolling average of a unit's output during PJM's peak-use hours," which fall between 3 p.m. and 6 p.m. during the months of June, July, and August, the company said.
For units that have operated for less than three years, PJM will calculate a class average of 20 percent of a wind turbine's rated capacity.
"We're applying a fair and practical method to allow wind turbines to provide generating capacity to the wholesale market," said Steven R. Herling, executive director of system planning at PJM. -C.H.
