How LADWP’s plans work

R-1A (Residential Service, Zone 1). In July the first 350 kWh a month cost 26.4¢ each; then 32.3¢ above 350 kWh a month, then 41.0¢ above 1,050 kWh a month. An average California home (571 kWh in July) goes past the first tier, so extra load such as an EV is priced higher. Fixed charge: $7.90 a month. Minimum bill: $10.00 a month.

R-1B (Residential Time-of-Use). Mid-peak 10 am–1 pm, Peak 1 pm–5 pm, Mid-peak 5 pm–8 pm on July weekdays; 4 of 24 hours carry the top price of 35.1¢. The cheapest July weekday hour costs 26.5¢, so moving 1 kWh out of the top hours saves 8.6¢. January weekdays range from 25.3¢ to 27.6¢. Weekends follow a different schedule from weekdays. Fixed charge: $12.00 a month.

Prices on this page are all-in per kWh, before taxes: base rates, supply and every per-kWh rider in the utility’s current tariff sheets. Your bill shows them as separate lines, and riders can change between tariff revisions.

As a cross-check, LADWP billed its residential customers an average of 23.84¢ per kWh in 2024 (revenue ÷ sales, EIA-861). A plan taken from URDB is shown only if its all-in price is consistent with that figure, adjusted for California’s price change since.
