Constellation NewEnergy First to Offer Load Reduction Services to Their Customers Using the APX Operated California Demand Reserve Partnership Program.

SANTA CLARA, Calif. -- APX today announced that Constellation NewEnergy (CNE) has become the first California Energy Service Provider (ESP) to offer load reduction services to their customers through the use of the APX operated California Demand Reserves Partnership Program (DRPP).

"APX is very encouraged to see a leading energy service provider like Constellation NewEnergy participate in the California DRPP," said APX Chairman & Chief Executive Officer Tom Lewis. "This APX operated partnership program provides an immediate and flexible insurance policy for power grid emergencies and can help reduce price spikes that can result when electricity supplies become tight. We hope that other energy service providers will follow Constellation NewEnergy's lead."

The DRPP is a government and business partnership, administered through the California Power Authority (CPA), designed to help to maintain a clean, reliable, and cost-effective electricity supply in California through business demand response. More importantly, the program encourages businesses to agree to reduce power usage when supplies are low due to weather extremes, power plant outages, or transmission system bottlenecks. Because businesses use about half of the peak electricity load during weekday afternoon hours, available supplies are immediately increased when businesses reduce usage or shift non-essential operations to non-peak usage times. Participating businesses are then compensated for choosing to reduce their power usage when it is most needed.

"CNE is proud to be the first ESP to enroll in and provide this critical load reduction service to our customers," said Jay Purcell, director of sales in CNE's California market. "At CNE, we take great pride in providing full and diversified Demand Response service solutions to our Direct Access customers in California. More importantly, our customers will have an ability to not only offset their energy costs, but will also contribute to the state's economic health by helping to reduce electricity consumption during critical periods."

APX is an industry leader in the development and operation of independent Demand-Side Management Programs. APX's proprietary system design nominates and selects load for curtailment, performs automated curtailment notification, and also publishes the settlements information for these transactions.
