Western Area Power Administration conducted a Grid Reliability—Impacts to Tribal Renewable Projects webinar in partnership with the U.S. DOE Office of Indian Energy Policy and Programs and DOE Tribal Energy Program July 25.
About 55 Tribal members and interested parties participated in the webinar with 112 registering for the event. Western’s Reliability Compliance Program Manager was the featured speaker, covering topics such as key definitions, reliability organizations, oversight process, standards and enforcement among other reliability considerations.
Western’s Renewable Resource Program Manager Randy Manion shared, “This webinar was the eighth in the Fiscal Year 2012 Tribal Webinar series coordinated by Western. Laurent Weber, Western’s Reliability Compliance Program manager, did a masterful job explaining complex issues.”
The webinar series is giving Western transmission and power marketing experts a platform to share their incredible knowledge and expertise with Tribal representatives, renewable energy developers and other important stakeholders.
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.
