California's Gas System in Transition

California’s energy system is undergoing a period of profound change. The state has committed to 100% clean electricity, a doubling of energy efficiency, widespread transportation electrification, and a carbon neutral economy by 2045. Given the state’s adopted decarbonization objectives and air quality policies, it should come as no surprise that changes to California’s gas distribution system will occur as well. The volume of gas flowing through California’s gas delivery system (gas “throughput”) will decline dramatically over time in response to state and local policies. The pressing question for California is how we can manage this transition to minimize societal costs and unfair burdens on the remaining gas customers, while also ensuring greenhouse gas (GHG) emission reductions, air quality improvements, and equitable outcomes among California’s communities.
