Housing Energy Connection Project (Final Technical Report)

This project expanded existing medium-voltage distribution to 33 households, a daycare, a mechanical shop, irrigation pumps, and a sewer lift station, all of which previously received electric service from the local electric utility. As part of the project, automatic meter reading (AMR) and advanced metering infrastructure (AMI) was installed to allow the Tribe to set up its own electric metering like a utility. The primary objective of this project was to expand the Tribe-owned electrical distribution to provide highly reliable electrical service to these existing loads. The objective was successfully met after project completion. The project reduced high costs for electric energy previously supplied by the utility, by supplanting utility-supplied electric power with Tribe-generated electric power. The project gave the Tribe greater independence from traditional power sources and provided jobs for the community.

Solar Canopy Expansion Project (Final Technical Report)

This project is a parking-lot canopy solar photovoltaic system, consisting of four canopy structures and 1,080 470-watt (W) modules. The nameplate rating of the project is 507.6 kilowatts direct current (kWDC) at Standard Test Condition (STC), and 448 kilowatts alternating current (kWAC). It is interconnected to the existing Tribe-owned medium-voltage micro-grid generation system via a step-up transformer and short medium-voltage line. This project offsets energy usage from more expensive existing sources, specifically the Tribe-owned gas-fired engine generators providing the primary power source for existing Tribal facilities and the electric utility, which provides an alternate source. The solar photovoltaic system is a renewable source, which has the benefit of reducing reliance on fossil-fuel burning sources. By reducing demand on existing Tribe-owned conventional generators, the project has avoided the need to add more conventional generation and has prolonged the lifespan of existing gas-fired engine generators. The project reduced energy costs and reliance on fossil-fuel burning power sources, increasing Tribe-owned generating sources and self-reliance, and prolonging the lifespan of existing generators. A side benefit to the project is the production of dozens of covered parking spaces in the existing parking lot.
