The Transmission Infrastructure Program Electrical District 5 – Palo Verde Hub project in Arizona’s Pinal and Maricopa counties reached a major
Completion of the 22-mile segment between ED5 and Test Track substations represents nearly half of the new and upgraded line construction needed to complete the project.
construction milestone recently with the completion of 22 miles of new 230-kilovolt transmission lines between ED-5 substation and Test Track substation.
The new segment of transmission line represents half of all new construction and line upgrades required for the project, which will increase transmission capacity to deliver renewable energy, primarily solar, to consumers in Arizona, southern Nevada and southern California.
Construction was completed three weeks ahead of schedule, saving Western and the project proponent money and keeping the project on track for early 2015 energization.
The next step in the project is to expand Test Track substation to accomodate the increased transmission capacity. At the same time, the other half of transmission line upgrades will continue through early 2014.
E.M.F. Three little letters that strike terror into many hearts, but why?
Donna Shay, a Colorado citizen, asked Western to conduct an electric and magnetic field reading at her cabin that sits just outside a 115-kilovolt transmission line’s right-of-way. EMF readings determined about 1 milliGauss of exposure near her front door.
Mostly, it’s because we don’t understand electric and magnetic fields, or EMF.
The truth is people come into contact with these fields every day. EMFs occur naturally, like the magnetic field caused by currents deep inside Earth’s molten core. Manmade fields are also created by common appliances and equipment we depend on every day, like talking on a cell phone or heating up lunch in a microwave.
At Western, our high-voltage transmission lines and substations give off EMF, which sometimes concerns landowners with lines over and near their property. To help allay concerns, Western’s electrical engineers will test landowners’ EMF exposures from our transmission lines on request. Read more »
Lineman Joshua Bailey of the Cody, Wyo., maintenance office completes a pre-trip inspection on the 100-foot aerial manlift the morning of Nov. 1 before he and four other crewmates depart for Hoboken, N.J., to help with power restoration after Hurricane Sandy.
Western sent dozens of linemen, electricians, vehicles and supplies and two of its three Bell 407 helicopters to help repair storm damage to the electric grid in some of the hardest hit areas of New Jersey.
Along with its sister power marketing administrations Southwestern and Bonneville, Western has responded to calls for assistance from the Department of Energy to get the Northeast powered as quickly as possible.
“Our hearts go out to all those who have been affected by this devastating storm,” said Anita Decker, Western Acting Administrator. “The President has directed the Department of Energy, Western and the other power marketing administrations to work with the Northeast Utilities and do all we can to accelerate power restoration to those affected by Hurricane Sandy. Western is proud to be part of this effort to help restore power as quickly and safely as possible.”
Western is providing daily updates and photos on its support to Hurricane Sandy at its website and Flickr account.
James Hirning, a Rocky Mountain transmission planner, talks about Western and transmission planning to engineering graduate students at the University of Denver Nov. 1.
Rocky Mountain transmission planner Jim Hirning talks with University of Denver engineering graduate students Nov. 1 about transmission planning in Western and the intricacies that go into devising how to keep the electric grid reliable in the coming decades. Transmission planning is an area of potential job growth for Western as new generation, particularly renewable, comes online and demand grows in the West. As of last year, Western had more than 11,000 megawatts of renewable energy in its interconnection queues and not enough people, or transmission, to work through the requests.
Western was one of 17 organizations presented a “Partners in Conservation” award by the Deputy Secretary of the Interior today at a ceremony in Washington D.C. for participation in the Colorado River Basin Water Supply and Demand Study.
The Colorado River Basin Water Supply and Demand Study is a joint effort among more than 70 Federal and state agencies, Native American tribes, environmental groups and other organizations to establish a common foundation for resolving future water supply and demand imbalances. According to Interior, it is the largest, most comprehensive basin-wide analysis ever undertaken and will serve as a model for watershed planning and planning for future growth and climate change near the Colorado River.

Hundreds of people attended NaturEner’s opening ceremony Sept. 14 for the Rim Rock wind farm just north of Cut Bank, Mont., to celebrate overcoming the considerable challenges in making the wind farm a reality.
“There was a time last summer when we were doubtful we were going to be able to pull this off,” said Greg Copeland, Development Director of the U.S. division of the Spanish-owned NaturEner. Read more »
The Bureau of Land Management recently released the scoping summary report for the proposed Southline Transmission Line project, ending the 90-day scoping period for the project environmental impact statement.
BLM and Western, as joint lead agencies in the preparation of the EIS, held six open houses in New Mexico and Arizona in May during the scoping phase. The scoping phase gives the public the opportunity to learn about a proposed project, share concerns and provide comments on what potential impacts should be analyzed in the draft EIS expected in 2013.
Major concerns discovered during the scoping process included the NEPA process and BLM’s management plan amendment, wildlife impacts and socioeconomic impacts.
Southline Transmission, LLC, proposes to construct, operate and maintain a 360-mile, high-voltage power line from Afton, N.M., to Saguaro substation northwest of Tucson, Ariz. About 240 miles would be new construction of a 345-kilovolt line on mostly BLM land while the rest would be an upgrade to an existing Western line. If completed, the line will add 1,000 megawatts of transmission capacity to the southwest.
On July 31, the Bureau of Reclamation announced the delay of a project to relocate Western’s high-voltage transmission lines near Yellowtail Dam in Montana from August to October because of increased environmental concerns.
“I applaud our hydropower partners at Western for their sensitivity to the potential ramifications of the outage associated with the relocation project,” said Dan Jewell, Area Manager for Reclamation’s Montana Area Office. “While these types of maintenance events are never risk-free, delaying the work until later in the year will help reduce that risk.”
The current location of the lines puts them at risk for the dangerous ice storms that occur in the area over winter, prompting a joint effort between Reclamation and Western to move the lines.
The relocation is scheduled to take about two weeks, and the outage requires Reclamation to bypass the water turbines. With the unusually warm summer and fall, agencies and environmentalists were concerned about the impact of not using the colder water at deeper water levels to power the turbines in August. Alternatives to move the water, including the holo-jets and spillways, could increase nitrogen or water temperature, potentially harming fish.
According to Friends of the Bighorn River blog, “With lake water temperatures already well into the 70′s, a slight mistake, miscalculation or unplanned natural or man-made event could have long lasting, devastating effects on the river where fish are already highly stressed from anglers, low flows, gas bubble trauma, irrigation return, warm water and habitat loss.”
The delay is thought to be a fitting compromise to ensure reliable electricity from Yellowtail Dam this winter and protection of the environment.
Western Area Power Administration is issuing a request for proposals for renewable energy certificates, or RECs, for five Federal agencies:
- U.S. Department of Energy, Oak Ridge National Laboratory
- U.S. Department of Energy, Los Alamos National Laboratory
- U.S. Department of Energy, National Nuclear Security Administration, Sandia National Laboratories
- U.S. Environmental Protection Agency, Superfund Program
- U.S. Department of Energy, National Renewable Energy Laboratory, Golden Field Office
RECs represent the environmental attributes of energy generated by renewable resources such as solar, wind, biomass or landfill gas, physically delivered into the electric grid.
For more information on how to submit an RFP or on the program, see the full press release.
Western recently published new webpages to publicize progress toward the objectives in Secretary of Energy Stephen Chu’s March 16 memo to the power marketing administrations.
The webpages advertise public involvement opportunities, including stakeholder meetings, and show how Western is progressing toward meeting the memo’s objectives.
While Western calls the section “Defining the future,” the agency remains committed to providing reliable, cost-based electric service to its preference power customers. The objectives in the PMA memo only call for Western’s leadership in “transforming our electric system to the 21st century to ensure our nation remains competitive in a global economy,” as Secretary Chu stated in his May 30 blog post.
“[Western] has an enormous opportunity to assume a leadership role in helping prevent future blackouts by making the organizational and operational changes necessary to enhance overall system operations and planning,” he added.
Be sure to check out the pages regularly as they will be frequently updated with more information through the end of the year.
