Title
Staff Report for a Resolution Authorizing the City Manager or His Designee to Execute an On-Bill Financing Loan Agreement with Pacific Gas and Electric Company to Provide 0% Interest Loan Financing and a Rebate Grant Through Participation in the California Wastewater Process Optimization Program
Staffreport
SUMMARY AND RECOMMENDATIONS
Staff recommends that the City Council approve a resolution authorizing the City Manager or his designated representative to sign an On-Bill Financing (OBF) Loan Agreement with PG&E, which allows the energy savings to pay for the capital costs associated with the purchase and installation of an energy efficient turbo blower to replace one of the current aeration blowers.
BACKGROUND
In its treatment operations, the Water Pollution Control Plant (WPCP) is the largest single consumer of electrical energy of all City facilities; the majority of that electricity powers the aeration tank blowers. To comply with the Climate Action Plan mandate to continue to evaluate opportunities to purchase high efficiency equipment, the City contacted the California Wastewater Process Optimization Program (CalPOP) regarding energy efficiency measures that could be implemented to reduce electrical usage. CalPOP provides no-cost engineering services to identify energy savings measures for wastewater treatment plants, while also providing incentives for installations that improve wastewater processes, reduce operating costs and save energy.
Analysis
At the City's request, a CalPOP engineer spent several days in 2011 at the WPCP analyzing Plant processes and data, specifically regarding the operation of the aeration basin. He subsequently prepared a Facility Audit Report (attached). This audit qualifies specific energy efficiency measures for CalPOP incentives.
The Audit's proposed modifications to the Plant would improve control of plant processes, and yield energy and operational cost savings for the Plant. Specifically, t...
