Summary

The Pueblo of Laguna Utility Authority proposes to evaluate opportunities on Pueblo lands to develop large-scale renewable-energy generation projects. The project's objectives are to improve the quality and reliability of electric service on the reservation, work to promote energy self-sufficiency, encourage economic development, and contribute a source of environmentally clean energy.

Project Description

The Pueblo of Laguna ("Pueblo") Utility Authority (PLUA) proposes to undertake a feasibility study to evaluate opportunities on Pueblo lands to develop large-scale renewable energy generation projects. The Pueblo's ongoing interest in renewable generation has focused on its indicated wind, solar, and biomass resources, which appear to be considerable. The proposed project, "Renewable Energy Feasibility Study," is designed to expand upon previous work done by the tribe in evaluating utility formation, generation development opportunities, examining options for creating self-sufficiency in energy matters, and integrating energy management with the tribe's economic development goals.

Objective

The project's ultimate objectives in considering renewable energy development are to improve quality and reliability of electric service on the reservation, work to promote energy self-sufficiency, encourage economic development, and contribute to environmentally clean energy. Analyses completed during the project will provide the Pueblo with the data it needs to proceed with development of renewable generation, whether as an owner or participant in future projects. And, if electric utility operations are ultimately part of the PLUA organization, the Pueblo intends to build renewable and/or hybrid renewable generation into its electric utility plans.

Scope

PLUA will carry out the study effort with 14 primary tasks, listed below. Some preliminary analysis of the tribal load assessment has already been completed, and a high-level resource analysis and a transmission analysis have been addressed in ongoing Pueblo projects. All remaining required tasks are included in project activities.

Project Location

The Pueblo of Laguna Indian Reservation ("Pueblo") encompasses 533,000 acres, north and south of Interstate 40, approximately 44 miles west of Albuquerque, NM, located primarily in Cibola County. The Pueblo of Laguna inhabitants have continuously occupied this land since the early 1400s. Recent U.S. Census Bureau population estimates indicate the reservation is home to 4,294 residents living in six unincorporated villages (Laguna, Mesita, Paguate, Encinal, Seama, and Paraje), representing approximately 1,300 households.
