Energy efficiency upgrades at water resource recovery facility are paying off for city
November 20, 2014
SAN LUIS OBISPO, Calif.— Energy efficient improvements underway at the Water Resource Recovery Facility (WRRF) are starting to pay off for the City of San Luis Obispo. This week, in response to the decision to install LED exterior lighting throughout the facility, the City received an energy rebate check from Pacific Gas and Electric Company (PG&E) for $10,000.
The lighting replacement is one of six projects that the City's Utilities Department is embarking on with PG&E in an effort to modernize the plant, save energy, help the environment and control costs.
"PG&E welcomes the opportunity to partner with San Luis Obispo on this ambitious energy efficiency program," said Pat Mullen, PG&E's local division director. "Replacing the facility's older, high pressure sodium lights with LEDs is expected to save the city around $6,300 a year in electricity costs. That's real dollars and we look forward to continuing to support the City in its effort to save even more money and reduce the facility's overall carbon footprint."
Through the partnership, PG&E is assisting the City in the development, design and implementation of more energy efficient equipment. This includes upgraded control systems and a new Combined Heat and Power (CHP) system that allows for the generation of on-site electricity for the facility using the natural bio-gas produced each day. Combined, these improvements will reduce the facility’s dependence on the electric grid while enhancing operational efficiency.
"The City is excited about this partnership with PG&E," said Dave Hix, Deputy Director of the City of San Luis Obispo's Public Utilities Department. "The WRRF represents one of the City's largest uses of energy. These important strategic investments will improve energy and operational efficiency at the facility and will help the City meets its social, environmental and economic stewardship goals."
The improvements to the WRRF are expected to be completed next year. They will help the environment by reducing the amount of greenhouse gasses that are released into the atmosphere. The upgrades will reduce carbon dioxide emissions by one million pounds annually. That's the equivalent of planting 378 acres of forest, taking 96 cars off the road or powering 69 homes.
