GROWTH AREA 3

GROWING WITH YOU,PLANNING FOR YOUCOSERV MEMBERS

Published: 09-2014

»What is CoServ’s relationship to Brazos Electric? CoServ is a not-for-profit electric distribution cooperative. As one of the 16 members of Brazos Electric Cooperative, CoServ depends on Brazos to provide bulk power to the area. CoServ serves the end-use consumers. CoServ purchases electricity from Brazos Electric, which transmits power from generation plants to substations. At substations, CoServ distribution lines pick up electricity and distribute it to homes and businesses.

»Why is new electric infrastructure needed? CoServ delivers power to more than 180,000 homes and businesses. Just 12 years ago, our utility served 65,000 meters using 16 substations. This averages out to 4,000 meters served per substation. Today, the company serves 183,000 meters using 27 substations. This averages out to more than 6,300 meters per substation. Our service territory covers the same physical area, but the infrastructure needs to keep pace with the tremendous growth in residential and commercial development. Systemwide, meters served per average substation has grown by about 57 percent. Infrastructure must grow to keep up with population growth. Over the past decade, the North Texas population has increased by more than 1 million people, with increases of 74 percent in Collin County and 68 percent in Denton County. More residents and businesses result in a greater demand for energy, which requires new electric infrastructure. The need is undeniable.

CoServ’s mission is to provide safe, reliable energy solutions. The circles on the front cover designate areas where CoServ has forecasted the need for new substations to serve significant residential and business development. Note that Growth Area 3 is in the initial stage of a proposed substation project involving our wholesale power provider, Brazos Electric Cooperative.

When CoServ identifies a new substation need, we look to Brazos to determine potential substation sites and assess potential power transmission requirements. Brazos is required to follow the Public Utility Commission (PUC) process for proposing projects by applying for a Certificate of Convenience and Necessity (CCN). A CCN outlines attributes of the line, proposes potential routes, describes the need and identifies potential impacts on the surrounding community and environment. The PUC ultimately determines and orders the substation location and transmission line route. (Open to the inside of this brochure for a diagram of the CCN process.)

Before filing a CCN application, Brazos is required to conduct civic and public meetings and notify affected property owners along proposed routes and substation sites. This process will begin in September for affected landowners in Growth Area 3 who will have ample opportunity to participate in the CCN process and express their views to the PUC. Visit CoServ.com and click on the growth map for more details.
