Department of Energy's Energy Savings Performance Contracts Stretch Budgets at the Bureau of Indian Affairs

Photovoltaic energy system at Sherman Indian High School,Riverside, CA

This photovoltaic energy system should provide nearly 7 kilowatts of clean solar electricity to the Sherman Indian High School campus.

Overview

The U.S. Department of the Interior's Bureau of Indian Affairs has found a good way to reduce energy costs, replace inefficient lighting and aging building equipment, and install renewable energy systems without huge increases in the BIA budget. The agency is doing all this by making use of the Department of Energy's (DOE's) Super Energy Savings Performance Contracts (Super ESPCs) at BIA schools and facilities throughout the country.

BIA's first four Regional Super ESPC projects alone represent $12 million in infrastructure improvements that will reduce energy use more than 40% at the four sites. Sherman Indian High School in Riverside, California, is one good example. This project features several energy-efficient technologies, improves the facility's infrastructure, and includes a solar electric system to help provide uninterrupted power. The project will reduce energy use by almost 40% at the school and trim operations and maintenance (O&M) costs by nearly $30,000 per year.

Background

In 1997, BIA energy manager Bill Coursey began discussions with staff in the DOE Western Regional Office in Seattle. He wanted to know if ESPCs would be a solution to a major backlog in infrastructure repairs and equipment maintenance at BIA facilities. They determined that ESPCs could help BIA reduce the backlog, maintain or improve the comfort of its facilities, and reduce utility costs. Among other projects, in 2000 a delivery order under the Western Regional Super ESPC was signed for work needed at the Sherman Indian High School in Riverside.

Sherman Indian High School dates back to the early 1900s. Located on 88 acres, this boarding school serves from 350 to 650 students in approximately 500,000 square feet of facility space. Before the Super ESPC retrofits, annual energy and water use at the facility was estimated at 3,756,000 kilowatt-hours of electricity, 140,743 therms of natural gas, and 36,818 cubic feet of water. Utility costs exceeded $450,000 per year.

Project Summary

SEMPRA Energy Solutions was selected as the energy service company for the Sherman Indian High School project under the Regional Super ESPC. SEMPRA agreed to install a new photovoltaic (PV) solar electric system as part of the project. The PV system had already been purchased with DOE funding, but it had not been installed because of budget constraints. Under the 22-year contract, SEMPRA guarantees the following:

These energy conservation measures (ECMs) provide new heating and cooling controls and greater energy efficiency at the site. New air-handling units give staff more time to maintain other systems around the campus. And a new computer station in one science classroom monitors the performance and output of the PV system, providing a basis for new curriculum materials.

The BIA maintains O&M activities for all the ECMs. SEMPRA is responsible for ensuring that all annual maintenance activities are carried out and for guaranteeing the performance of the rooftop units.

Benefits of Using ESPCs

Before starting the Super ESPC process, Coursey estimated that the backlog in needed infrastructure improvements and equipment repairs throughout BIA exceeded $750 million. Since then, he has made a significant dent in that backlog in four facilities, and he hopes to keep going until all viable BIA Super ESPC projects are completed. Through Super ESPCs, BIA can make repairs before they become emergencies and stretch funds already allocated to various projects, saving on future energy and water costs.

Lessons Learned

During the first four Super ESPC delivery order projects, BIA staff learned that the ESPC process requires a high level of commitment and effort. For example, to ensure success, each project requires 200 to 300 hours of dedicated staff time to uncover energy-saving opportunities, evaluate them, and oversee implementation. Each project also requires the dedication of maintenance and engineering staff as well as flexibility and support from management and instructional staff during construction work.
