East Valley Energized by New SRP Line

A major new transmission project that will bring additional electricity and increased reliability to the Valley is now fully energized.

The final phase of the Palo Verde-Southeast Valley-Browning (PV-SEV) 500-kilovolt (kV) project was placed into service for the first time this month. This marked a major milestone for SRP, as it was the last segment of a new 150-mile transmission line that runs from the Palo Verde Nuclear Power Plant area near Tonopah to the Browning Substation located in east Mesa.

“We are glad that after 14 years this project is in service,” said John Underhill, SRP’s senior director of System Operations. “The entire East Valley will benefit. This new transmission line, which originates in the West Valley, will now bring that power all the way around to the east. This provides us with another power source into that area, where little or no generating plants are being built east of the Santan Generating Station.”

Prior to the PV-SEV line, SRP depended on a single 500kV transmission line to bring energy from the Palo Verde energy hub to the East Valley. The final line segment, which spans 100 miles, is the last component of the PV-SEV 500-kV project that began construction in 2006, after six years of planning and approvals.

The project resulted from a study by SRP and other Arizona electric utilities, and approval by the Arizona Corporation Commission, showing a need for increased transmission capacity to meet increasing energy demands created by business and residential growth in central Arizona and Tucson. The study concluded that energy deliveries in central Arizona required a new transmission line and other equipment additions, significant upgrades to existing equipment, and the project overall would increase system reliability.

“Years of planning and hard work by many entities, including SRP employees and contract personnel, resulted in a quality project that will serve the needs of the customers for many years to come,” said Dan Hawkins, senior project manager of Major Transmission Projects for SRP.

The project has included the building of five large substations — Pinal West, Duke, Pinal Central, Abel and Dinosaur — and additions to the existing Hassayampa and Browning substations. Also as part of the project, two 500/230-kV transformers at Pinal Central and one 500/230-kV transformer at Duke, located in Pinal County, were energized May 30 and June 12, respectively. The PW-SEV-BOB Project will serve customers in Pinal, Pima and Maricopa counties.

“The design and building of the 150-mile system is really remarkable,” added Underhill. “I received a firsthand aerial view as our staff inspected the line in a helicopter. It’s impressive how we were able to build the line to blend in with the landscape.”

Partners in the transmission project include SRP (project manager), Tucson Electric Power Co., Electrical District #2, Electrical District #3, Electrical District #4, Western Area Power Administration and the Southwest Transmission Cooperative Inc.

SRP is the largest provider of electricity to the greater Phoenix metropolitan area, providing electric service to more than 990,000 customers.

Energy Consortium’s Roadmap puts state of path to build industry

Imagine Arizona as the energy hub of the Southwest — where major regional transmission lines tie into infrastructure in the state and serve a growing regional demand for energy. Arizona would be a place where an increasing percentage of jobs are related to the energy industry, whether in manufacturing, generation, transmission, energy efficiency, service or technology innovation. Many of these jobs would be higher-wage jobs requiring a skilled labor force fed by Arizona’s schools and universities. Arizona could be a hub of energy-sector jobs, with factories making equipment for the industry and power plants shipping electricity to neighboring states via new power lines, all contributing to a better economy.

That is the essence of the Arizona Energy Consortium’s Energy Roadmap, which the group hopes with be a catalyst for the state’s energy industry in the same way Arizona’s Bioscience Roadmap helped the state increase bioscience jobs by 41 percent and helped increase the number of bioscience establishments by 27 percent during its 10-year plan.

“It was important to create this document to give the energy industry a unified voice and direction,” said said Michelle De Blasi, co-chair of the AEC and a shareholder at Greenberg Traurig. “The energy industry is going to be here forever. We are always going to need energy. So the Roadmap was designed to make the industry better for everyone — consumers, developers, legislators. So it was critical that we get it right.”

This is the vision the Roadmap hopes to realize over the next decade: Arizona is the energy hub of the Southwest, with a diverse energy mix supporting reliable transmission, a strong base of manufacturing facilities, increased numbers of higher wage jobs, and world-class research institutions, resulting in increased economic development for the state and region.

Once that vision is realized, De Blasi said the state can expect to reap these benefits:
• Enhanced job creation and higher-wage jobs within Arizona
• Increased state economic revenue
• Enhanced energy export potential
• Heightened energy self-sufficiency and national and state security
• Increased transmission reliability
• Continued low cost energy

“This Roadmap is going to help Arizona be looked at differently from outside its borders,” said Chris Davey, co-chair with De Blasi of the AEC and president of EnviroMission, which is developing a solar tower in Western Arizona. “The Roadmap will create a sense of certainty, which appeals to the finance community. So when they are looking to invest, that certainty creates a more attractive environment for developers and investors.”

Davey and De Blasi said they will be rolling out the Roadmap this year, presenting it to groups throughout the state. For more information on the Roadmap, visit aztechcouncil.org.
