Promote lowest feasible carbon emissions

Description: Community Choice Aggregation (CCA) programs serve their customers by providing different power products offering varying percentages of clean power, up to 100% renewable. Examples of CCAs leading on decarbonization include Silicon Valley Clean Energy which has 50% renewable and 50% hydro for 100% GHG-free default service; MCE which has a nearly 99% carbon-free mix of renewables, large hydro, and nuclear; and Clean Power Alliance which offers 100% renewable. CCAs can and do have 100% renewable energy as a planning goal, e.g., MCE proposes to be 100% renewable by 2025, providing it is cost effective; and San Diego Community Power has a similar goal for 2035 which is 10 years earlier than state policy. However, conservation and efficiency should always be prioritized over power supply as prescribed by California’s loading order and Sierra Club policy.

Goal: Promote lowest feasible carbon emissions that can meet or beat utility rates as default power product for local CCA jurisdictions, offering options for 100% clean energy

Measurement: Percent of customers of community choice aggregation programs who choose 100% clean power

Time to Implement: The best time for a city or county to choose 100% clean energy as the default choice for its ratepayers is when the jurisdiction joins or starts a CCA
