No Pumped Storage Hydropower

BACKGROUND

Initially filed with the Federal Energy Regulatory Commission (FERC) in 2021, the Black Mesa Pumped Storage Project (BMPSP) is a massive, Pumped Storage Hydropower (PSH) project proposed along Black Mesa plateau’s northern rim. This project proposed to build 4 large reservoirs along the upper rim of Black Mesa and 5 along the base of the plateau. This massive project was filed under three applications, BMPSP North, East and South. The developers came to the communities looking for support for a project that lacked a definitive water source. The application was denied in 2024 due to both community opposition and concerns raised from the Navajo Nation. Almost immediately following the denial by FERC, the developers began to push for different versions of the same project and targeted communities separately for their approval. These new projects are going by the name the Kayenta Pumped Storage Hydropower Project and the Chilchinbeto Pumped Storage Project. 

What is Pumped Storage Hydropower?


Pumped storage hydropower pumps water uphill during low electricity prices and then releases it back downhill through generators at night or when electricity prices are high, generating both electricity and revenue. The developers propose to use Black Mesa’s 2000’ escarpment for the upper reservoir and lower. This PSH project is not to be confused with hydrogen, which is a fuel and is also being pushed elsewhere on the Navajo Nation.

KEY CONCERNS:

Water


These pumped storage projects are threatening to take more groundwater, which will further impact the delicate hydrologic system of the region. The project plans to tap into the region’s groundwater or the San Juan River for their operation. This continued pumping of large quantities of precious groundwater may disrupt the hydrologic balance forever.

Biodiversity


The entire northern edge of Black Mesa is designated as a “red zone” by the Navajo Nation under the Biological Resource Land-Use Clearance Policies and Procedures (RCP), and therefore development is "severely restricted." The pumped-storage hydropower project will significantly affect the land, wildlife habitats, and the wildlife that calls this region home.

Ethics


There is no clear process established for engaging communities. Without clear protocols, communities are venerable to misinformation, coercion, and no grievance processes. The ethical practices of the local leadership needs in engage all community members on this project. The developers are not truthful in the ways they engage the community by being selective with community voices.

Credibility


Pumped storage hydropower is new to the Navajo Nation. These projects have raised more questions than they have support due to the numerous unknowns and what-ifs. There is a lack of historical water data and information on how the aquifers work. Lastly, threatening the community with "use it or lose it" language in these discussion is a big concern.

PUBLIC MEETINGS


If you are a registered voter of the Kayenta Chapter, the chapter is hosting community public meetings on the Kayenta Pumped Storage Hydropower Project. We encourage registered voters to attend these meetings to voice your concerns about the project. In the future, the Kayenta Chapter will vote on a land withdraw resolution for this proposed project. Visit the Chapter website at the beginning of each month to stay up to date on these future public meetings.

What is FERC?

The Federal Energy Regulatory Commission, aka FERC, is an independent agency that regulates the interstate transmission of electricity, natural gas, and oil. FERC also reviews proposals to build liquefied natural gas (LNG) terminals and interstate natural gas pipelines, as well as licensing hydropower projects. All non-federal hydroelectric power projects in the United States are permitted and regulated by FERC under the Federal Power Act (FPA). Read More...

What's Next?

Tó Nizhóní Ání, Diné C.A.R.E., Black Mesa Trust, and the Center for Biological Diversity have filed motions to intervene urging the Federal Energy Regulatory Commission (FERC) to deny the preliminary permit application for the Chilchinbeto Pumped Storage project southeast of Kayenta on the Navajo Nation. The groups’ motion cites problems relating to industrializing Black Mesa and its groundwater, including impacts to local communities and families, depletion of rivers, groundwater, and springs, and impacts to wildlife and their habitat.

It cites the applicants’ failure to consult with the Hopi Tribe, failure to consider water use in the context of regional drying, and their mischaracterization of support from the Navajo Nation’s Resources and Development Committee. The groups' motion details incomplete, misleading, and infeasible aspects of the proposed project and calls for affected communities to participate in any further study development.
