Integrating controllable demand into real-time, security constrained economic dispatch.
Audrey Zibelman, et al.
Historically, grid operators tapped into voluntary load reduction as a last resort for keeping the lights on. But now, smart grid technologies and dynamic pricing mechanisms bring vastly greater potential for using load as a dispatchable resource. Effective implementation requires advanced technologies—and also foresight in creating programs, policies, and market mechanisms.
The long-predicted future of distributed generation is now becoming a reality. Customers increasingly are installing and operating behind-the-meter generation systems, creating challenges and opportunities for utilities. ConEdison’s experience demonstrates the dangers and challenges, as well as the opportunities for becoming partners with utility customers.
Learning lessons from PSE’s residential demand response pilot.
Utilities and regulators increasingly are considering direct control of residential load to help manage the grid. Evaluating the recent experience of one winter-peaking utility—Puget Sound Energy—provides insights into best practices for ramping up direct load control.

Policymakers and industry seek a formula to assure competitiveness and resource adequacy.
New Jersey’s bid to force prices downward in PJM’s capacity market not only raises the alarm about market manipulation. It also reveals a dilemma that’s preventing new generation from being built. Incumbent interests and political motivations make PJM less attractive to investment than it should be.
Idaho Power has more wind power than it can use—so much that it’s costing its ratepayers a bundle. It wants out, so it won’t have to buy from all the small wind farms that claim “QF” status under the 1978 PURPA law.
Almost a year and a half has passed since FERC issued Order 745, declaring demand response to equal to power supplies in wholesale markets. Yet uncertainty surrounds the order’s implementation, and third-party aggregators are struggling to define their role.
