Transmission Headquarters

Distribution Line Crew

Located adjacent to the Mid-America Industrial Park, the Transmission & Engineering Headquarters is close to the bulk of GRDA’s industrial customers, thereby shortening response time. However, a skilled corps of transmission technicians is also able to provide prompt, reliable service to all reaches of the GRDA service area. Supplementing the facility is a transmission service center, located near Cushing, OK, on the western edge of the GRDA system.

How GRDA Ensures Reliability

Membership in the Southwest Power Pool (SPP).
GRDA has been a member of the Southwest Power Pool since 1969. This organization, which was established in 1941, ensures the reliability of electric service to nearly seven million customers in a 500,000-square-mile region. The pool’s interconnected power grid stretches across parts of eight states including New Mexico, Texas, Oklahoma, Kansas, Missouri, Arkansas, Louisiana and Mississippi. Members of the power pool, in times of emergency, can receive power across this grid from other power pool members. SPP is headquartered in Little Rock, Arkansas.

The North American Electric Reliability Corporation (NERC).
In 1968, the electric utility industry formed the North American Electric Reliability Corporation to promote reliability among the bulk power suppliers of North America. NERC’s nine regional reliability councils and one affiliate encompass all the power systems of North America (United States and Canada). Because its power grid links bulk power suppliers in all parts of the United States, the Southwest Power Pool, and all its members, like GRDA, play an extremely important role in the operation of the NERC system.

Membership in the Western Systems Power Pool. (WSPP).
WSPP is an organization of electric utilities that have joined together to open up opportunities in the power marketing field. In August of 1995, GRDA joined WSPP to better position itself for the deregulation and open markets of the electric industries future. As a member, GRDA can make surplus power marketing transactions via computer.
