SRP price plan calculator
Enter your monthly use for each season and pick the routine closest to your household. We apply SRP's published prices to every hour of a typical month and compare what a year would cost on each plan.
| Plan | Winter / month | Summer / month | Summer peak / month | Per year | vs lowest |
|---|---|---|---|---|---|
| Basic (E-23) | $129 | $199 | $297 | $2,167 | — |
| Conserve 6–9 p.m. and Save (E-28) | $133 | $206 | $313 | $2,248 | +$82 |
| Manage Demand 5–10 p.m. and Save (E-16) | $138 | $212 | $327 | $2,327 | +$161 |
- E-28: about 15% of your use falls in on-peak hours. Moving a tenth of your highest-priced use to the cheapest hours would save roughly $39 a year.
- E-16: about 23% of your use falls in on-peak hours. Moving a tenth of your highest-priced use to the cheapest hours would save roughly $29 a year.
- Estimates include the monthly service charge but not taxes, city fees or other riders. Your usage pattern is an assumption; see how we calculate.
How the plans differ
- Basic (E-23) charges the same price at every hour: 11.03¢ in winter, 12.10¢ in summer and 14.04¢ in July and August.
- Conserve 6–9 p.m. and Save (E-28) charges 40.26¢ from 6 to 9 p.m. on July and August weekdays but only 6.67¢ from 8 a.m. to 3 p.m. Other hours cost 12.82¢.
- Manage Demand 5–10 p.m. and Save (E-16) has lower energy prices but adds a demand charge for your highest hourly use between 5 and 10 p.m. on weekdays — up to $17.86 per kW in July and August.
Who tends to save on Conserve 6–9 p.m. and Save
Because the summer-peak evening price is almost three times the Basic price, E-28 works best for homes that can pre-cool before 6 p.m., run laundry, dishwashers and pool pumps between 8 a.m. and 3 p.m., and charge an EV outside 6–9 p.m. Homes that run large loads in the evening every weekday may pay more than on Basic.
About the Manage Demand estimate
SRP bills E-16 demand as the average of each weekday's highest 60-minute use between 5 and 10 p.m. We estimate it from a typical day and add 30% because real days are spikier. Running the oven, dryer and air conditioner at the same time in that window can raise it a lot, so treat this plan's result as rough.
