Load-Management Programs Canceled

Fortnightly Magazine - May 15 1997

The Virginia State

Corporation Commission has authorized Delmarva Power and Light Co. to close two experimental load-management tariffs to new customers.

Nevertheless, the utility said it would continue to call upon existing program participants to mitigate system emergencies throughout the year.

One program, established in 1988, offered billing credits to customers who agreed to establish a firm service level and then curtail load to that level at the company's request during peak management billing months of June through October. Under the other program, "Energy for Tomorrow," similar credits had been offered since 1992 to residential customers who had agreed to allow Delmarva to cycle their electric central air conditioners, heat pumps or electric water heaters on and off during the summer months.

After conducting a study of the proposed tariff revisions, the commission's staff found that the cost of purchased power and new generation had decreased significantly since the riders were established and that the programs were not cost effective under the utility's 1995 integrated resource plan.
