Rate Schedules & Tariff Analysis
LADWP C&I rates are a municipally-set, two-part-plus structure: fixed service charge, capacity charges (facilities charge per kW, plus monthly demand charges at the A-2/A-3/A-4 levels), and volumetric energy charges that are seasonal and time-of-use for larger customers. On top of base rates, every bill carries pass-through adjustment factors — the Energy Cost Adjustment (ECA), Electric Subsidy Adjustment (ESA), and Reliability Cost Adjustment (RCA/IRCA) — which can move quarterly and materially affect the all-in rate.

The only formal third-party path today is the LADWP Building Benchmarking program, which uploads aggregated monthly electric and water usage to ENERGY STAR Portfolio Manager after the building owner submits authorization forms. There is no Green Button or EDI program.
Does LADWP support Green Button or an API for customer data?▾
No. LADWP has not implemented Green Button Download My Data or Connect My Data, and offers no customer-facing data API. Its Oracle Utilities platform could support these standards in the future, but nothing has been announced.

Small commercial accounts use a general service schedule, while larger accounts move to time-of-use schedules with energy and demand (kW) charges. Commercial accounts are billed monthly. Rates are set by the LA Board of Water and Power Commissioners, not the CPUC.
