Commission OKs new load control program

 

The Idaho Public Utilities Commission has approved a second Irrigation Load Control Program for customers of Rocky Mountain Power that could save up to 45 megawatts of demand on Rocky Mountain’s system.

 

Under the program, eastern Idaho irrigators who volunteer to participate would get financial credit for allowing Rocky Mountain Power (formerly Utah Power) to interrupt service during times of peak demand. This program differs from an existing irrigation load control program in that the company can interrupt service remotely from a central network server in Boise. Rather than service interruptions taking place on a scheduled basis – as is the case with the existing irrigation load control program – interruptions would be at the company’s discretion. The network server will communicate with customers, using either cell phone or e-mail technology to alert them of impending interruptions to service, or “dispatch events.”

 

The pilot program also differs from the existing program in that credits are yearly rather than on a monthly basis.

 

Rocky Mountain Power will allow eligible customers to enroll on a first-come, first-served basis.

 

Total curtailment per participating customer would be limited to no more than 65 hours during the 2007 irrigation season per customer. Dispatch events would occur anytime between 2 and 8 p.m., Mondays through Fridays during the irrigation season. Rocky Mountain Power will credit the bills of participating customers at the end of the irrigation season. Participants can opt out of a dispatch event up to five times during the 2007 irrigation season. If participants opt out more than twice, the credit paid to the participant will be reduced by the replacement cost of the energy during the dispatch event.

 

Rocky Mountain’s application proposes limited participation on a first-come, first-served basis during the 2007 irrigation season. The company will report to the commission regarding participation levels and amount of load reduction achieved.
