When you sell demand response back to the grid, how much capacity are you now not buying?
When customers sell demand response into a regional capacity market (such as PJM’s Reliability Pricing Model, known as the RPM), how much credit should they earn for agreeing to curtail demand and alleviating stress on the grid — that is, for reducing the market’s need for generating capability and capacity reserve margin? And further, should the amount of credit depend on whether the customer works with market aggregators, known both as CSPs (“Curtailment Service Providers”) or ARCs (“Aggregators of Retail Customers”)? One view would pay customers for the full extent of their curtailment of demand — known as its “Guaranteed Load Drop” (GLD). The other would limit capacity credit to the customer’s prior load history — “Peak Load Contribution,” or PLC. The answer may well dictate whether regulators continue to treat “energy” and “capacity” as two distinct concepts.

Which path leads to the smart grid?
A fierce debate has erupted in the utility policy community, with battle lines drawn within FERC itself. In the effort to improve system efficiency, two competing alternatives stand out: to build the smart grid on large-scale demand response (DR) programs, or to build it around consumer behavior in retail markets.

Economists take sides in the battle for DR’s soul.
Back when the U.S. economy and power consumption still were bubbling, PJM reported in August 2006 that customer curtailments during a week-long August heat wave had generated more than $650 million in market-wide energy savings—all at a mere $5 million cost, as measured in direct payments made to the demand response (DR) providers, set according to wholesale power prices prevailing at the time. Where else but the lottery can you get an instant payoff of 130-1?
