To give an overall picture of the city of Los Angeles’ electricity consumption, the total consumption for the city, the average consumption per resident, and the percent change between years was calculated. This section will start with the residential numbers then the commercial. These numbers were calculated from the two reports provided by LADWP.
The total residential electricity consumption did not change much around 8 billion kWh between 2009 and 2012 (Figures 2.1 and 2.2), though there was some fluctuations. For the period between 2009 and 2012, the total residential electricity consumption increased by 0.18%. In particular, the electricity consumption declined from 2009 to 2010 by 4%. The average consumption per resident for those years was around 2,100 kWh. After 2010, annual consumption increased by 1.26% 2010 to 2011 and by 3.24% 2011-2012 (Figure 2.3).Figures 2.1 Change of Total Residential Electricity Consumption 2009-2012
Figures 2.2 Chnage of Average Residential Electricity Consumption 2009-2012
Figures 2.3 Percentage Change of Residential Electricity Consumption 2009-2012
The total commercial consumption declined from 14.47 billion kWh in 2009 to 14.39 billion kWh in 2012, down by 0.58%; this is greater than the change of residential electricity consumption (Figures 2.4 and 2.5). Again, the annual change was not big, around 1%. The biggest change occurred between 2010 and 2011, down by 1.22%.

LADWP has initiated a number of Energy Efficiency Programs. Below will be a quick description of each of these programs. Most programs target commercial clients while some programs target residential clients, while select programs are available for both commercial and residential programs.
Commercial Programs
- Chiller Efficiency Program:
- LADWP’s Chiller Efficiency Program (CEP) is offering cash rebates that benefit the owners and operators of buildings who use chillers for space conditioning. Rebates are available for air and water-cooled chillers of all types and sizes, including standard and non-standard installations. The installation of a new energy-efficient chiller will result in substantial savings over its lifetime.
Chiller rebates are based on their actual size and the percentage that the chiller’s Integrated Part Load Value (IPLV) exceeds Title 24 Standards. The Non-Standard Part Load Value may be used for Water-Cooled Centrifugal Chillers where the cooling tower system performance meets qualifying criteria (additional requirements are in the chiller section of the application). LADWP reserves the right to require a Factory Certified Test for chiller applications. Please check with the Chiller Team for specific testing requirements.
- Commercial Lighting Efficiency Offer. The CLEO Program can help reduce businesses’ electricity bills and the cost of new lighting equipment when the business decides to retrofit existing fixtures with state-of-the-art, energy-efficient lighting technologies. Rebates help make a wide variety of the latest energy-saving measures extremely cost-effective to install.
- Custom Performance Program. LADWP offers incentives for the installation of energy saving measures, equipment or systems that exceed current Title 24 or minimum industry standards but are not included in other LADWP Non-Residential Energy Efficiency Programs.
- Custom Express Program. LADWO expanded Custom Performance Program to include a simplified rebate menu (Custom Express Program) for specific measures to efficiently control energy use of networked computers, ENERGY STAR® certified office equipment, and other plug loads.
- Energy Efficiency and Conservation Block Grant Program. As a part of the City of Los Angeles Energy Efficiency and Conservation Block Grant (EECBG), the LADWP received over $8 million in funding to implement new energy efficiency programs to supplement the existing array of services and rebates. Three new rebates will be offered through this grant, including a cool roof rebate and whole house fan rebate for residential customers and a retrocommissioning rebate for commercial customers.
Refrigeration Program: LADWP’s Commercial Refrigeration Program can help you reduce your electricity bills and the cost of new refrigeration equipment when you replace or retrofit existing refrigeration equipment with state-of-the-art, energy-efficient refrigeration technologies. Rebate measures include ice machines, solid and glass refrigerator doors, door gaskets, night covers, strip curtains, vending machine controllers, and other energy efficient measures.
- Residential Programs:
Consumer Rebate Program (CRP). LADWP offers the Consumer Rebate Program (CRP) to our residential customers to promote the use of energy-efficient products. This program is designed to both educate and encourage LADWP residential customers to purchase and install qualifying products in their home. To see a list of the rebates being offered by the LADWP. Traditional programs include those target Appliances, Building Products, heating and cooling equipment.
Home Energy Improvement Program (HEIP).An assessment of residents’ home will be performed by trained LADWP technicians to assist the owners in identifying the most appropriate and effective improvement . During the assessment, trained technicians will identify the areas in the residents’ home where cost-effective energy efficient upgrades and repairs should be made for the improvement. The home report is then forwarded to LADWP skilled repair technicians to complete the work and after a quality assurance review is made of the home to ensure that the work has been performed properly.
Energy Upgrade California. The program offers two upgrade packages and is designed to help customers take a comprehensive, “whole-house” approach. Multiple improvements, made at the same time, work together to make homes more comfortable, improve air quality, help save energy and possibly lower energy bills. To help offset costs, eligible customers can receive incentives of up to $4,500 for complete home upgrades.
Programs for both Residential and Commercial Clients:
- CLEO Rebate Program. The CLEO Program can help you reduce your firm's electricity bills and the cost of new lighting equipment when you retrofit existing fixtures with state-of-the-art, energy-efficient lighting technologies. Rebates help make a wide variety of the latest energy-saving measures extremely cost-effective to install. So, if you are a non-residential LADWP customer, let us put our energy to work for you with this exciting program.
There have been several important changes to the CLEO program requirements, so you must submit your rebate application using only the new CLEO program forms. All CLEO documents may be obtained from links on this website, or by emailing a request to cleo@ladwp.com.
- New Construction Program. LADWP and the Southern California Gas Company® (SoCalGas) are working together on New Construction Programs that offer incentives that benefit owners and developers of new residential and commercial buildings.
- Solar Incentive Program. LADWP is constructing and operating solar photovoltaic (PV) systems on its facilities and municipal buildings throughout the City of Los Angeles. In addition to constructing and operating solar facilities, LADWP aims to encourage the development of residential and commercial solar systems. The Solar Photovoltaic Incentive Program provides an incentive payment to LADWP customers who purchase and install their own solar power PV systems. Most recently, LADWP is currently developing a FiT Program to allow customers to sell renewable energy produced from their own systems. In particular, the “Go Solar L.A.!” program is designed to reduce customers’ cost of installing solar PV systems to meet the goals of the state’s SB1 “million Solar Roofs”. In doing so, our goal is to spark the installation of reliable, well-designed solar generating systems throughout the city and to help establish a robust and viable solar PV industry in Los Angeles.
- Home Energy Improvement Program: offers residential customers the opportunity to improve the energy and water performance in their homes, which can improve their comfort level and potentially reduce their energy and water cost.

Strategies for reducing traditional fossil fuel energy usage and emissions have become a significant issue for all stakeholders at the local, state, and national level. Policy makers, utility companies, environmental groups, and individuals all have a stake in reducing traditional energy usage and promoting sustainable energy production. The Los Angeles Department of Water and Power Board of Commissioners have adopted the goal of achieving 10% energy efficiency by 2020.
Substantial funding has been and will continue to be committed to programs designed to reach this goal. These programs have included rebates for residential and commercial users, outreach programs conducted by LADWP, Energy Upgrade California and non-profits, and direct install programs for small business and low income residents. As funding for energy efficiency increases, it is vital to collect and analyze data to assess the effectiveness of programs, their effect on long-term behavior change among users and the distribution of implementation in different areas of the city. Answers to these questions are critical in assisting policy and decision-makers in further improving energy usage efficiency.Note: information on the LADWP programs is extracted from its website: LA Department of Water of Power
