Going all-electric may require increasing your electric service or panel size to accommodate greater electrical loads from appliances and electric vehicles. In single-family homes, if the panel is 100 amps or greater, existing electrical service may be sufficient with panel optimization, making efficient use of existing service and breakers with load management technology and appropriate appliance selection. Panel optimization not only avoids added costs from electrification, it also enables faster and more widespread building decarbonization with existing electrical infrastructure.
Determining the necessary panel size for your home is the consumer's decision, not PG&E's. If the consumer determines electrical service needs to be increased, PG&E's Added Load process must be followed.
On 9/7/22, the cities of Oakland and San Francisco held a workshop on electrical service upgrades for single-family buildings with PG&E and Tom Kabat (slides, resource list and recording). Minute marks for the recording are below listed below.
A multifamily and commercial buildings version of the workshop was held on 9/28/22 featuring John Neal from the Association for Energy Affordability and PG&E. Slides, recording, and notes and Q&A from the webinar are available.
