COUNCIL AGENDA REPORT

AGENDA DATE: June 17, 2014 TO: Mayor and Councilmembers FROM: Facilities Division, Public Works Department SUBJECT: 2013 Annual Energy Report RECOMMENDATION: That Council receive a status report on the City’s energy conservation and efficiency efforts. DISCUSSION: The Annual Energy Report summarizes energy-related activities that took place during the 2013 calendar year. City staff uses the report to inform Council and the public about recent activities and current energy trends. Key issues discussed in the 2013 Annual Energy Report are summarized below. • The City’s total electricity usage for the year remained relatively flat at 25.94 million

kwh despite increases due to the ozone project at Cater Water Treatment Plant and the reopening of the Airport’s historic terminal. Through energy efficiency projects, rate restructuring and other measures, the City was able to mitigate these increases and reduce the City’s expenditure on electricity by approximately .5% in 2013.

• In 2013, the City’s total natural gas usage increased by about 4% to 162,000

therms. This is largely due to aging HVAC infrastructure at the Police Department and the Cabrillo Arts Pavillion. Both of these buildings are slated for remodeling in the next few years, which includes the installation of upgraded systems.

• The cogeneration system at the El Estero Wastewater Treatment Plant has been in

operation since December 2013. This system can supply up to 75% of the Plant’s electrical needs and is expected to save the City approximately $55,000 annually in electricity costs.

• The City completed the construction of the Fats, Oils and Grease receiving facility,

which will eliminate a significant amount of truck trips to far-away disposal sites, as well as provide additional fuel for the cogeneration system at the Plant.

Council Agenda Report 2013 Annual Energy Report June 17, 2014 Page 2

• The City’s involvement in Southern California Edison’s Direct Install Program is an

excellent example of a successful energy project. In 2013, the City received $146,000 in lighting upgrades and retrofits that will save the City roughly $30,000 per year in electrical costs.

In summary, this year’s energy projects have continued to manage and offset the City’s growing electrical and natural gas demand and save the City dollars. The energy efforts performed by the City’s energy team since its inception in 2008 have resulted in a 2.5 million kWh energy reduction and $465,000 in annual cost savings. City staff is looking forward to building on the 2013 efforts in the coming year. The Annual Energy Report has been made available for review at the City Clerk’s Office.
