| Local Policy Description: | The City of Los Angeles plans to continue and improve various energy efficiency programs which encourage renewable energy usage and reduce energy consumption
City 10 Percent Green Power
The Green Power for a Green LA Program, launched in 1999, provides DWP customers with the option to directly purchase energy produced from renewable resources such as solar, wind, geothermal, biomass and small hydroelectric. LAWA already participates in the program, with an anticipated purchase of 50 percent green power for LAX and Van Nuys Airport by 2010. Other city departments have the opportunity to significantly contribute to the reduction of CO2 emissions by also purchasing green power. The City Council has instructed city departments to develop plans for purchasing 10 percent green power by 2002. The EAD proposes that once the city has achieved a 10-percent level of green power purchases, additional purchases of 5 percent annually be considered until all city departments purchase green power at a rate of 25 percent.
Digester Gas-to-Energy
Hyperion Treatment Plant is scheduled to convert to Class A biosolids processing in 2003-2004. Based on information provided by Bureau of Sanitation facility engineers, this change in process will result in an estimated increase of 12 percent in digester gas production to 2,773 million cubic feet per year. The gas will continue to be piped to Scattergood Generating Station and converted to electricity. For the Terminal Island Treatment Plant, no electricity production is projected for 2010. Anticipated changes in the digestion process will require more heat energy, and the available digester gas will be burned in boilers to meet this demand.
DWP 2000 Integrated Resource Plan
The DWP and the City Council recently adopted the 2000 Integrated Resource Plan. The main component of the plan relevant to the Energy C.A.P. is the projected change in generation fuel mix, with less dependence on coal. The generation fuel mix for 2010 is the following: coal (39%), natural Gas (38%), nuclear (10%), hydro (4%), purchases (1%), and green power (8%). This will result in an average decrease of 16 percent in CO2 emissions per kWh produced and consumed. This is measured by either a system emission factor (in tons of CO2 per gigawatthour) or a CO2 coefficient for electricity (measured in tons of CO2 per million Btu of electricity produced). In addition, the plan contains other important strategies to reduce energy consumption and CO2 emissions, including implementing demand-side management, distributed generation and renewable energy programs.
Energy Efficiency Conversion of City Streetlights
The 2010 forecast for the streetlights sector assumes a full conversion of the city's streetlight network from less energy-efficient incandescent and mercury vapor to high-pressure sodium or metal halide lamps. The conversion program is currently underway and approximately 80 percent of the existing network of 238,633 lamps already has been converted. Based on 1999 information provided by the Bureau of Street Lighting, 17,368 incandescent lamps and 22,739 mercury vapor lamps remain to be converted to high-pressure sodium or metal halide (which achieves similar energy savings). The reduction benefit of converting this last increment of the streetlight network equates to 75,715 tons CO2 per year. It also is projected by the Bureau that by 2010, the network will grow by about 24,000 new lamps, all of which will be installed as high-pressure sodium or metal halide.
Energy Efficiency Retrofits of City Buildings
Energy efficiency retrofits of designated GSD-controlled buildings will be fully implemented by 2010. The program provides for the installation of comprehensive energy management systems, including mechanical, electrical, lighting and water system upgrades. Based on the pilot retrofit program conducted at 16 buildings from 1996-1998, the average annual savings in electricity and natural gas were 13-14 percent. An energy savings estimate of 10 percent was used for the 2010 forecast.
ENERGY STAR-Compliant Office Equipment
The City Council has adopted a city policy supporting the purchase of energy-efficient office equipment and directing city departments responsible for procuring office equipment to indicate in bid specifications that products must be ENERGY STAR-compliant (unless such products are not available). The Council action also instructed city departments to designate staff to perform routine checks to ensure the proper configuration of power management features, and to conduct regular training and outreach to build awareness of energy efficiency.
Los Angeles World Airports Purchase of Green Power
LAWA is participating in the green power program with an initial purchase of approximately 10 percent green power. LAWA.s goal is to reach 50 percent utilization by 2010, equating to an emission savings of 118,688 tons per year of
CO2.
