Rosemead, CA, U.S.A. --- (METERING.COM) --- May 28, 2009 - California investor owned utility Southern California Edison (SCE) is to undertake a participating load project utilizing smart grid technology company BPL Global’s Power SG® Demand Management solution.
The solution will monitor and assess the feasibility of using the demand response of aggregated residential air conditioning load to serve as electric power reserves bid into the wholesale electricity market. This aggregated demand response, with voluntary short duration curtailment for each air conditioner, could potentially avoid triggering additional generation to balance electricity supply and demand.
“We are excited about the possible benefits to our customers and the environment that this project represents,’ said Larry Oliva, director of SCE tariff programs and services. “Using new technology to refine our partnership with residential customers participating in the voluntary air conditioning cycling program is a key attribute to advancing our leadership in demand response programs.”
SCE operates one of the largest demand response programs involving residential and commercial air conditioning in the world. SCE has enrolled 330,000 customers in this optional program that allows the company to cycle air conditioner compressors in case of grid emergencies. With this project, SCE is exploring whether electricity used for residential air conditioning can be managed to provide electric power reserves by enabling localized reduction in load within minutes with minimal customer impact.
The Power SG® Demand Management software solution will provide real time verification to assess SCE’s ability to manage residential load as electric power reserves. It monitors the actual load of selected residential air conditioners in near real time. Centralized system control enables monitoring each load according to its attributes for utilization as electric power reserves. Actual ramp-up, shed and ramp-down of each individual load is monitored and validated. This information can be reported for a single air conditioner or in aggregate.
Keith Schaefer, BPLG’s CEO commented: “This effort produces a precise, predictable, and verifiable asset that SCE can use to quickly increase their operating margin through low cost and environmentally friendly load management methods instead of building new generation capacity.”
