The Bureau of Reclamation is releasing approximately $52 million in previously inaccessible post-retirement benefit funds to support projects to help the Hoover Dam operate better in drought conditions.
Planned improvements include the replacement of three older turbines with wide-head turbines, which the bureau said will operate more efficiently amid declining Lake Mead levels.
As one of the nation’s largest hydropower facilities, Hoover Dam has historically delivered up to 2,074 megawatts of hydropower capacity — supplying electricity to roughly 1.3 million people across the southwest.
Due to the unprecedented drought, generation has decreased by about 30%. Lake Mead’s level was recently recorded at just 1,048 feet.
Without intervention, additional declines would risk the facility’s long-term financial viability and could place added pressure on customer rates, the bureau said, noting that Hoover Dam’s capacity could drop from earlier estimates of 1,302 megawatts to just 382 megawatts.
The turbines — which are designed to operate at lake elevations below 1,035 feet — are expected to restore at least 160 megawatts of hydropower capacity and will help mitigate impacts caused by the ongoing drought.
Early estimates put the cost between $8 million and $13 million per turbine.
The funds were collected because of an administrative error and remained inaccessible for years.
The unlocked funding source will play a crucial role in strengthening the facility’s reliability and supporting long-term hydropower production for customers in Nevada, Arizona and California, the bureau said.
