FAQ

We use base charges and per-unit rates from official provider and municipal sources for each city in San Diego County. Electric may reference a CPUC-regulated investor-owned schedule (PG&E, SCE, or SDG&E), a municipal utility (for example LADWP, SMUD, or a city PUD), or another published tariff; water, sewer, and trash follow city, district, or franchise programs. Each city page shows assumed usage (kWh, gallons) and outbound links to primary sources.
California counties typically include many jurisdictions. Electric delivery territory, community choice aggregation enrollment, water/sewer enterprise boundaries, and solid-waste programs all follow the provider that serves your meter—not the county name on your mail. Compare city pages and match the legal name printed on your bill.
Open the county internet providers page at /california/county/san-diego-county-utility-costs/internet-providers for FCC-backed research merged for cities we model here, plus an address-level comparison tool. Availability is still specific to your building and unit.
Each city page shows a 'last verified' date and links to official sources. Enriched county overviews add CPUC and utility hubs below. Confirm current rates on the utility’s or government’s primary tariff page before making decisions.
No. SDG&E delivers electricity (and may deliver gas) while the City of San Diego or another water retailer bills potable water and sewer for your address. Each portion of the bill follows a different adopted schedule.
