Cap & Trade Program

The Cap and Trade Program (Program) is one of the state’s key implementation tools intended to encourage reduction of greenhouse gas (GHG) emissions as part of Assembly Bill 32 (AB 32), passed in 2007. Under the program, which is overseen by the California Air Resources Board (ARB), GHG emission reductions are accomplished through the use of economic pricing mechanisms that place a cost on the emissions of GHGs. Anaheim Public Utilities, like all other electric utilities in California, is a covered entity under the Program and, as such, is required to participate in the program. 

As the Utilities generates electricity from its fossil fuel power plants, GHG emissions are also generated. In order to comply with the program, the Utilities must surrender allowances, essentially permits, equal in number to the total metric tons of GHG emissions from these electric generation facilities. The program gives incentives to the Utilities, and all covered entities, to reduce GHG emissions in order to reduce costs for procuring the allowances necessary to cover their GHG emissions.

Anaheim Public Utilities Compliance


It is the Utilities goal to minimize the costs necessary to comply with the program requirements by employing a variety of measures that include, but are not limited to, managing how we generate electricity and how we acquire allowances. At this time, the program is not expected to result in any additional costs to customers; however, it does have the potential to add additional costs of up to $5 million annually, based in part, upon the future costs and the availability of allowances in the market.

The status of the Utilities compliance with the program requirements is provided to the City Council on a regular basis. Additionally, this program is only one of many regulations that are impacting the Utilities as a result of AB 32. Other regulations include the Renewable Portfolio Standard (RPS), which requires all California electric utilities to meet 33% of their customer needs with renewable energy resources, as well as energy efficiency and conservation requirements.
