OG&E expands testing for smart grid IVVC

Oklahoma City, September 12, 2011 — Oklahoma Gas and Electric Co. has expanded testing of smart grid technology-supported equipment that can help the utility deliver energy more efficiently.

During the summer of 2011, an additional 42 circuits equipped with capacitor controllers and 16 circuits with automatic reclosers are under scrutiny in the Oklahoma City area to better determine if integrated volt var control can reduce peak demand for power on the grid.

IVVC is an engineering solution that provides OG&E with automated intelligence to control voltage and power on the distribution lines.

Results from testing in the summer of 2010 on four primarily residential circuits in Norman, Okla., indicates IVVC has the potential to reduce peak demand for power from .8-2.4 percent.

In addition, last year's test results demonstrated that IVVC produces power factor improvement during those times when demand for power is not at its peak.

The investor-owned utility is partnering with The Structure Group for program management of its three-year smart grid deployment, which includes the installation of smart meters, a secure wireless network and smart equipment on OG&E's distribution system to increase reliability and reduce operational expenses.

This summer, OG&E is completing the second half of a demand response study with 6,000 residential and business customers to reduce peak demand. Interim results from last summer show every customer segment had a reduction in peak usage with the greatest reductions during the highest peak price days and by study participants using programmable communicating thermostats.

Peak demand reductions enabled by smart grid technology on the distribution system and in customers' homes and businesses are forecasted to reach 350 MW by 2017.

OGE Energy is the parent company of OG&E, a regulated electric utility with more than 782,000 customers in a service area spanning 30,000 square miles in Oklahoma and western Arkansas; and of Enogex, currently with 8,000 miles of pipe, nine processing plants and 24 billion cubic feet of natural gas storage capacity.
