OG&E to deploy Silver Spring demand response solution

OG&E will deploy a price-response program that exclusively runs on its smart grid network without the need for redundant networking technologies

Redwood City, Calif. December 15, 2011 — Silver Spring Networks, a smart grid networking platform and solutions provider, announced that Oklahoma Gas and Electric has selected Silver Spring's end-to-end demand response solution to expand OG&E's pioneering, smart grid-based peak-reduction programs to all customers in its service territory.

OG&E will deploy a price-response program that exclusively runs on its smart grid network without the need for redundant networking technologies. OG&E intends to leverage the energy efficiencies achieved through its demand response program and integration of wind power to achieve its goal of avoiding the building of fossil-fueled generation plants until at least 2020.

OG&E's decision to expand its DR program to all customers in its territory is the culmination of four years of work with Silver Spring and analysis of the results from several pilot programs. Throughout the project, OG&E has focused on price-based DR, in which higher prices for energy during peak demand and lower prices in off-peak times incent customers to shift usage to off peak.

OG&E's program is paving the way for a new approach to DR, one driven by customer choice rather than direct utility control. In last summer's pilot, 98 percent of participating customers saved money and they reduced their peak energy use 12 percent to 35 percent using various in-home technologies.

OG&E's goal is to make an estimated 70 MW of load available for peak reduction next summer. Scaling this DR deployment to all customers highlights the confidence OG&E has in both the effectiveness of the Silver Spring demand response solution needed for residential peak reduction and the device interoperability enabled by the ZigBee Smart Energy Profile specification.

Silver Spring is delivering the overall DR solution to OG&E, including UtilityIQ Demand Response Manager, the back-office DR software; CustomerIQ, the customer engagement solution; installation services, software, and tools to support customer recruitment and in-premise installation; in-home devices; and on-going program support.

Unlike alternative DR solutions that require a broadband Internet connection and addition of a costly home gateway, the Silver Spring DR solution operates entirely across the utility's smart grid network. Silver Spring has partnered with Corix for device installation and Energate for programmable communicating thermostats.

The performance of the Silver Spring network has been instrumental in OG&E's ability to deploy DR throughout its service territory. Consistent meter reachability and high-performance networking have delivered the successful interval reading essential to enabling time-of-use readings. Focusing on industry standards such as an end-to-end IPv6 networking platform and ZigBee Smart Energy Profile has enabled an ecosystem of partners.
