FERC on Feb. 18 issued a preliminary permit to Daybreak Power for the Navajo Energy Storage Station [P-15001].
The $3.6-billion, 2,210 MW project would create a new upper reservoir at Arizona's Lake Powell, where the 1,320 MW Glen Canyon Power Plant generates hydropower via the Glen Canyon Dam.
"The facility will sit outside of critical habitat areas of endangered species, does not tap into groundwater or inundate any waterways, and will recycle water from Lake Powell with negligible water loss as the facility runs through its daily pumping/power generation cycle," the company said.
WildEarth Guardians, the Center for Biological Diversity and Save the Colorado all filed comments to FERC opposing the permit application.
The Navajo Nation filed to intervene in the matter, arguing that the preliminary permit should not be granted without its consent and approval of all leases, permits and rights of way required under Navajo Nation law, according to FERC's order issuing the preliminary permit.
