Buyers of desert homes often ask a seller for a year of utility bills, and in most markets those bills are a fair preview of the costs ahead. La Quinta is different right now. Its electricity comes from the Imperial Irrigation District, and IID's residential rate schedule has changed underneath those bills. A summer 2024 statement was priced on a base energy rate of 11.69 cents per kilowatt-hour. The same kilowatt-hours in 2026 are priced at 22.30 cents, and a third step to 24.38 cents is already approved for 2027.
The city's own resource page names IID, not Southern California Edison, as La Quinta's electric provider. A buyer comparing La Quinta with SCE-served parts of the valley is comparing two different utilities, each with its own rate history. For a large home that runs air conditioning from May through October, the fair question is what the home's usage will cost on the schedule that applies over the years the buyer owns it.
The Bills Describe a Tariff That Has Been Replaced
IID's 2025–2028 rate update took effect February 1, 2025. It changed residential pricing in two directions. The base energy rate rose in three steps, and the Energy Cost Adjustment, an extra per-kilowatt-hour charge that used to move with fuel and market costs, was reduced to zero.
| Residential charge | Before Feb. 2025 | 2025 | 2026 | 2027 | 2028 |
|---|---|---|---|---|---|
| Base energy rate per kWh | 11.69¢ | 19.76¢ | 22.30¢ | 24.38¢ | 24.38¢ |
| Monthly customer charge | $9.60 | $10.50 | $11.40 | $12.25 | $12.25 |
IID's residential schedule records a board resolution dated January 21, 2025, and shows the 22.30-cent rate and $11.40 customer charge as effective January 1, 2026. On a home's bill history, that leaves two breakpoints in less than two years, with a third scheduled for 2027.
Because the ECA went away, the old bills don't simply understate costs by the gap in base rates. Before the update, the ECA added a variable amount on top of the base rate. Imperial Valley Press reported factors of 3.00 cents in September 2024 and 3.20 cents in October 2024. IID's own estimate of the net effect for 2025 was an increase of $29.81 a month for an average residential customer using 1,070 kilowatt-hours a month. That figure already accounts for the ECA going to zero, and it covers only the first of the three steps.
The Same Kilowatt-Hours on Each Year's Schedule
To see what the path means for a single household, run IID's own 1,070-kilowatt-hour average through each year's base energy rate and customer charge. These are base charges only, before taxes, any adjustment schedule and any bill credit:
- 2025: about $211 in energy plus the $10.50 customer charge, roughly $222
- 2026: about $239 in energy plus $11.40, roughly $250
- 2027: about $261 in energy plus $12.25, roughly $273
A golf-course estate with a pool and a long cooling season can use far more than 1,070 kilowatt-hours in July, and the dollar gap grows with every additional kilowatt-hour. A 2024 bill for that home doesn't capture the 2025 increase, the 2026 increase or the one coming in 2027.
Buyers weighing La Quinta against an SCE-served city will see SCE's posted figure. SCE lists an average residential rate of 34.5 cents per kilowatt-hour as of its October 1, 2026 change, or 33.3 cents with the California Climate Credit. SCE's average customer behind that number is on a time-of-use plan using 500 kilowatt-hours a month, which puts the average bill around $188. IID's 22.30 cents is a base energy charge, and its benchmark household uses more than twice as much power. The two figures don't produce a like-for-like bill comparison. The more meaningful difference is the one between the schedule a La Quinta seller paid on and the one a buyer will pay on.
The Summer Credit Depends on Last Year's Costs
IID's summer bill credits can make the next year's bills look better than the rate table suggests, but they change from year to year. In March 2025, The Desert Sun reported that IID would cut summer bills by 25% and refund $81 million, about six weeks after the multiyear increases were approved.
The 2026 version was smaller. On April 21, 2026, IID announced roughly $48.4 million in credits, an estimated 12% refund on June through September usage, showing up on July through October bills. IID said the money came from lower-than-expected 2025 costs, attributed to cooler temperatures, reduced demand and lower fuel and purchased-power expenses. Board Chairwoman Karin Eugenio described the action this way:
"When costs come in lower than expected, we believe those savings should be returned to the people we serve."
In practice, the credit works as a rebate drawn from the prior year's surplus. If a seller's summer 2025 bills reflect a 25% cut, they reflect an action that has not been repeated at that size. The 12% credit on bills issued this month depends on how 2025 turned out. Summer 2027 credits will depend on 2026 costs, which are not yet known.
Rooftop Solar Is Worth What Its Program Pays
Many country-club homes come with solar panels, and how much the panels save depends on the IID program they are enrolled in. IID says its legacy Net Energy Metering program has reached its cap and is closed to new applications. New interconnections go onto the Net Billing program unless they fit a listed extension category.
Under Net Billing, power the home draws from the grid is billed at the regular retail rate. Excess generation sent back to the grid is paid at 6.98 cents per kilowatt-hour, a variable rate tied to IID's lowest wholesale solar contract cost. With the 2026 residential base rate at 22.30 cents, a kilowatt-hour the home uses itself avoids more than three times what an exported kilowatt-hour earns. IID's distributed generation schedule also says excess generation does not carry forward into later billing months. Each step in the retail rate makes self-consumed solar more valuable, and the export rate is set separately, under its own contract-cost formula.
IID's published materials leave a gap here for a buyer. The NEM schedule and the utility's home-sale FAQ don't say whether a legacy NEM arrangement stays with the property when it is sold, and they don't set any term limit. The home-sale page focuses on ownership. A system that was purchased outright is likely to count as an asset, while a leased system or one financed through a property-tax-linked loan may count as a liability. Four questions about a solar-equipped listing can be answered directly with IID and the seller:
- Is the system enrolled in legacy NEM or in Net Billing?
- Is the system owned, leased or financed through a property-tax-linked loan?
- If it is leased, does the buyer have to qualify to take over the lease?
- How does IID handle the account and the program enrollment when ownership changes?
Why the 2027 Step Could Still Change
The rate path is approved, but a dispute over who sets it is under way. Under the Riverside and Imperial LAFCO governance study, IID's board is elected by voters in Imperial County divisions, so Riverside County customers have no vote in IID board elections. A coalition of Coachella Valley customers filed a verified petition in Riverside County Superior Court on August 24, 2026, under Case No. CVPS2606927, The Desert Review reported. The filing alleges that about 61% of IID's electric meters are in the Coachella Valley portion of Riverside County. It asks the court to restore Riverside County rates to their pre-February 1, 2025 levels going forward and does not seek refunds. These are a litigant's allegations, not findings. The report put the motion hearing at November 13, 2026.
Local cities have also changed their own channels into IID. The City of La Quinta notes that IID's board voted on November 19, 2024 to disband the Energy Consumers Advisory Committee as of December 31, 2024. That committee had 10 Coachella Valley members nominated by valley cities and Riverside County. In 2025, La Quinta, Indio and Riverside County formed the Coachella Valley Power Agency, administered by CVAG, to pursue coordinated local governance for IID-served valley territory. At its December 1, 2025 meeting, CVPA reported that IID had approved cost-share agreements on November 18, 2025 for substation work, including a La Quinta Avenue 58 expansion estimated at $23.2 million, with construction expected to begin in early 2027.
None of this has changed the 2026 schedule. It does mean the 2027 figure in the table above may still move, either through litigation or through negotiation between the valley and IID.
FAQ
Is every La Quinta address served by IID? The city lists IID as its electric provider. IID describes its Coachella Valley service area as a footprint shaped by agreements, including a service-boundary agreement with SCE, and its service map page asks customers to check a specific address.
Does time-of-use pricing change the picture for a large home? It can. IID's optional residential TOU schedule, effective January 1, 2026, charges 47.77 cents per kilowatt-hour for May through October weekday usage from 4 to 9 p.m. and 13.65 cents off-peak. From November through April, weekday 5 to 9 a.m. and 5 to 9 p.m. usage is 35.28 cents and off-peak is 17.64 cents. Whether the plan lowers a bill depends on when the house uses its power. IID's 2026 Shift & Save campaign offers eligible customers a one-time $250 prepaid card for enrolling.
Is there a fee to add solar after closing? IID charges a $255 solar inspection fee, subject to change, on interconnection applications received after May 1, 2025. All applications go through its PowerClerk platform.
At a country-club home, the electric bill can be one of the larger carrying costs, and in La Quinta right now the seller's bill history and the rate schedule you'll actually pay on are out of step.
