LC Power prepares as Hoover Dam faces hydropower challenges

by

Lincoln County Power District General Manager Dane Bradfield recently discussed the issue as utilities across the West continue planning for reduced hydropower production from Hoover Dam.

Lincoln County residents are unlikely to see any immediate impacts from ongoing challenges at Hoover Dam, but local power officials are keeping a close eye on what declining water levels at Lake Mead could mean for future electricity costs.

The concern centers around Lake Mead’s elevation. Energy officials have warned that if the reservoir falls below 1,035 feet above sea level, Hoover Dam could lose a significant portion of its generating capacity because many of its turbines were not originally designed to operate under lower water conditions.

For Lincoln County, the issue is particularly important because roughly 70% of the district’s power supply comes from Hoover Dam resources. Bradfield said the district has already taken steps to prepare. Lincoln County Power District regularly forecasts future demand and secures power purchases well in advance.

Bradfield said the district has enough power secured through 2026 and is now looking ahead to future years.

“Our plan right now is to make those purchases a year in advance and just be ready for when the bottom falls out of it,” Bradfield said.

While reliability remains strong, Bradfield said future costs are a larger concern.

“We are anticipating that the cost of hydropower will probably go up,” he said.

Hydropower has traditionally been one of the least expensive energy resources available to utilities throughout the West. As water levels decline and power production decreases, the cost of that electricity could increase.

Bradfield said utilities throughout the region are already discussing how rising hydropower costs could affect future energy planning.

Lincoln County Power District has also expanded its use of solar resources in recent years, helping offset reductions in Hoover generation that have already occurred.

Despite the uncertainty surrounding future reservoir levels, Bradfield said the district continues to monitor conditions and make long-term plans to ensure reliable service for Lincoln County customers.

For now, residents should not expect any immediate disruptions. The larger question will be how future water conditions at Lake Mead affect the long-term cost of power throughout the West.
