Pumped Storage Hydropower Technology

Pumped storage hydropower (PSH) technology is a type of utility-scale battery invented over 100 years ago to store electricity. The International Hydropower Association says PSH represents 94% of all energy storage solutions deployed globally . The United States Federal Energy Regulatory Commission (FERC) has authorized 24 PSH projects currently in operation with a capacity of over 16 GW . The technology is ideal for storing renewable energy and is the low-cost technology to store electricity for 10 hours or more when the sun doesn’t shine or when the wind doesn’t blow.

The infrastructure consists of two reservoirs that can hold water separated by natural elevation change. The Chilchinbeto Pumped Storage Hydropower Project has about 1,500 feet of elevation change with one reservoir on Black Mesa and the other reservoir at the base of Black Mesa. The reservoirs are connected by a pipe, also referred to as a tunnel or penstock. When electricity is stored - typically in Arizona when the sun shines and electricity is cheap - water is pumped from the reservoir at the base of the mesa to the reservoir at the top of the mesa. When electricity is needed, the PSH operates as a hydroelectric facility: water flows down the pipe, through a generator producing electricity, and then to the lower reservoir.

The Chilchinbeto Pumped Hydropower Storage Project is a closed-loop project so water moves from the base of the mesa to the top of the mesa and then back down to the base of the mesa over and over and over. After construction, the only water needed will be to replace water that evaporates. The project will be designed to minimize evaporation by installing floating solar panels or other methods. Importantly, once the project is constructed, the water infrastructure will be available over 90% of the time for use by the Navajo Nation and its people.

In summary, pumped storage hydropower is a proven technology and ideal to complement renewable energy sources such as solar and wind power. The Chilchinbeto Pumped Storage Hydropower Project will not only help the region transition to clean energy, but also provide water infrastructure to the Navajo Nation.

INTRODUCING THE CHILCHINBETO PUMPED STORAGE HYDROPOWER PROJECT

Since the closure of the Navajo Generating Station was announced and Nature and People First recognized the opportunity for a pumped storage hydropower project, Nature and People First has met and made presentations to Navajo Nation leaders, Chapter leaders and members and people located in and near the project area. Among the Navajo Nation organizations with whom Nature and People has visited are:

• Chilchinbeto Chapter of the Navajo Nation
• Navajo Nation Council's Natural Resource and Development Committee
• Navajo Tribal Utility Authority
• Division of Economic Development
• Division of Natural Resources

Regional utilities have expressed interest in potentially purchasing services from the project and requested that the project begin the permitting process by applying for a Federal Energy Commission Preliminary Permit. Navajo Nation leadership were contacted for input and then Nature and People First applied for permits on Black Mesa on a wide area to give as many options as possible for the Navajo Nation, Chapters and local people as well as flexibility for such considerations as geology, biodiversity and cultural artifacts.

In parallel, Chilchinbeto Chapter expressed interest in learning more about a potential project and offered opportunities for its leadership, members and grazing permittees to attend presentations. Chilchinbeto Chapter first voted to enter into a dialogue with Nature and People First and then voted to support the project. The Chilchinbeto Chapter interest in the project is described below.

The project is expected to be located on about 100 acres on top of Black Mesa and about 100 acres on the base of Black Mesa and create directly or indirectly about 1,000 jobs during construction and 100 permanent jobs. The final design will be subject to discussions with Chilchinbeto Chapter and Navajo Nation administration, agencies, Council, and stakeholders as informed by engineering, environmental, archeological, cultural and other studies.

The Chilchinbeto Chapter

The Chilchinbeto Chapter has voted to support the Chilchinbeto Pumped Storage Hydropower Project to bring jobs and economic development to our Chapter and people. The project is anticipated to bring directly or indirectly 1,000 jobs during construction and 100 permanent jobs. For Chapter members living on Black Mesa, the project will improve the road to the top of Black Mesa which is frequently impassable. Just this winter a snowmobile was rented to bring a member food and medicine.

The project will make water available to all Chapter members. Once the project is complete, over 90% of the project's water infrastructure will be available for the Chapter and the Nation. The Chapter members living on Black Mesa will no longer have to drive 2 hours ... and only when the road is available ... to get water. The direct benefits of the road and water will come from the use of only about 100 acres on the mesa and 100 acres at the base of the mesa - less than the grazing area for two cows.

Importantly, the project follows the Diné teaching of ‘T’áá hwó’ ajít’éego’ self reliance or self determination. As President Nygren has said, “The Navajo Nation has always been an energy Nation, hands down. We don’t live next to Phoenix. We don’t live next to metropolitan areas. But what we do have is what we’ve always had, energy. Whether it’s oil and gas, whether it’s coal, solar, no other tribe can even match us.”

Former President Jonathan Nez and former Vice President Myron Lizer signed the Navajo Sunrise (Háyoolkáál) Proclamation. President Nez said the proclamation “creates a new economic vision for the Navajo people through healing the land, fostering clean energy development and providing leadership for the energy market.” He went on to say, “This is nothing new to us as indigenous peoples — being stewards of the land and using what Creator has given us in terms of natural resources.” “It’s time for our land to heal and become green again,” said Nez, "What we’re doing today is planting a seed for our future and for our younger generation”. Chilchinbeto Chapter has voted to support this type of hydro-electric plant because it brings: jobs, water and economic development.

With the economic development, the project can bring benefits to the Nation, the Chapter, and the local people such as help with:

Water

Jobs

Roads

Agriculture

Broadband

Economic
Development

Grazing

Bioversity
