Of every region and season in Mexico’s published domestic electricity schedule, the most expensive is the one that applies to a Los Cabos villa between April and October. Under the charges published for January 2026, the high-consumption rate in Baja California Sur summer topped the national range at roughly 7.049 pesos per kilowatt-hour.
That is the number owners eventually find. The one that decides whether it applies to them is harder to see, because classification runs on a rolling twelve-month average — which means the decision that puts a villa onto that rate is made roughly a year before there is any reason to look for it.
By the time the bill makes the problem obvious, the problem is already twelve months old. And it cannot be reversed inside a season.
This is a briefing on how that mechanism works, what it currently costs, and which parts of it an absentee owner can actually influence. It is an operations question rather than a tax or ownership question, which makes it one of the few large line items in Cabo where the outcome is genuinely decided by how the property is run.
What DAC actually is
Mexican residential electricity is federally subsidized, and the subsidy is delivered through a block structure. The first tranche of monthly consumption prices at a low rate, the next tranche higher, the tranche above that higher still. Most households never leave the lower blocks.
DAC — Doméstica de Alto Consumo, high-consumption domestic service — is what happens when an account leaves that system entirely.
The classification is not a penalty rate applied to consumption above a threshold. That is the most common misunderstanding, and it matters. When an account crosses into DAC, the blocks disappear. There is no subsidized first tranche any more. Every kilowatt-hour on the bill, from the first one, prices at the unsubsidized rate.
That structural detail is why the jump is so much larger than owners expect. A household that was consuming most of its power inside the cheap blocks does not move from a low rate to a slightly higher one. It moves from a blended rate to a single high rate applied across the whole bill.
The trigger is the Límite de Alto Consumo — the high-consumption limit. CFE calculates a rolling average of monthly consumption across the trailing twelve months and compares it against the limit for the account’s base tariff. Exceed it, and the account reclassifies automatically. There is no discretion in this, no application, and no appeal on grounds of circumstance.
The limit is on your receipt, not in your city
Here is where most published guidance on this topic goes wrong, including guidance written specifically about Los Cabos.
CFE assigns a base tariff class by locality, based on average summer temperature. Hotter localities get a more generous limit, on the reasoning that air conditioning in extreme heat is not discretionary consumption. The published monthly limits run as follows.
| Base tariff | Monthly consumption limit |
|---|---|
| 1 | 250 kWh |
| 1A | 300 kWh |
| 1B | 400 kWh |
| 1C | 850 kWh |
| 1D | 1,000 kWh |
| 1E | 2,000 kWh |
| 1F | 2,500 kWh |
CFE publishes these limits directly, and the current version should be treated as the authority over any secondary summary, including this one.
The temptation is to look up “Cabo San Lucas,” find that it sits in a hot-climate band, and assume the most generous limit applies. Do not do this.
Public sources disagree about which class Los Cabos services fall into, and they disagree because the answer is not uniform. Some widely circulated tariff guides place Cabo San Lucas in the hottest band. A Baja California Sur state subsidy announcement, by contrast, described the large majority of Los Cabos accounts as sitting in a middle class with a materially lower limit. Both can be accurate at once, because tariff assignment is made at the locality and service level rather than at the municipal level.
The gap between those two readings is roughly threefold. An owner who budgets against the wrong one is not making a small error.
The resolution is straightforward and takes thirty seconds. The tariff class is printed on the account’s own receipt, near the top, in the field labelled Tarifa. It is also visible in the CFE Contigo app and the online account portal. That code is the only authoritative answer for a specific property, and it is worth confirming for every villa under management rather than assuming a market-wide default.
The same receipt carries the consumption history, which is the second number that matters. The trailing twelve-month record is the input to the classification, and reading it tells an owner how much headroom actually remains.
What it costs
The DAC schedule is regionalized and seasonal. Under the charges published for January 2026, the energy component ranged from roughly 5.557 pesos per kWh at the low end to roughly 7.049 pesos per kWh at the high end, with a fixed monthly service charge of approximately 142.41 pesos on top.
Baja California Sur in summer sits at the top of that range. Of every region and season combination in the published domestic schedule, the one that applies to a Los Cabos villa between April and October is the most expensive in the country.
A note on all of these figures. CFE applies a monthly adjustment factor to domestic rates, on the order of a third of a percent per month, so the schedule drifts upward across the year. The numbers above are the January 2026 published charges and were current as of this writing in August 2026. They should be confirmed against a current receipt or the CFE published schedule before they go into any model. Anything quoted here is a reference point, not a live rate.
What that looks like on an actual villa is worth working through. Take a property averaging 3,500 kWh a month across a summer of high occupancy — a plausible figure for a six-bedroom house running multiple air-conditioning zones, pool equipment, and a commercial-scale kitchen, though it varies enormously with construction, glazing, and how the property is operated. Building stock differs sharply by community on exactly these variables, which is one reason a consumption benchmark borrowed from a neighbour is usually a poor guide; the housing profiles in Pedregal and Palmilla are not comparable loads.
At the top DAC energy charge, that consumption bills at roughly 24,700 pesos for the month. Add the fixed charge, then value-added tax at 16 percent, then whatever municipal public-lighting levy applies locally, and the month lands somewhere near 28,800 pesos before local charges. At an exchange rate around 17 pesos to the dollar, that is roughly 1,690 dollars for a single month of electricity.
These figures are illustrative. They are built to show how the components relate rather than to forecast what any particular property will bill, and actual consumption varies widely with the building, the season, the occupancy pattern, and the equipment installed.
Why it takes a year to undo
The rolling average is what makes this line different from every other operating cost in a Cabo villa.
An owner who discovers the classification in August, understands the cause, and immediately corrects it does not get relief in September. The high months that caused the reclassification remain inside the trailing twelve-month window until they age out of it. Consumption has to sit below the limit long enough to pull the average back down, and the higher the earlier months ran, the longer that takes.
There is a reclassification path. Once the trailing average has genuinely fallen below the limit, an owner can present the consecutive receipts to CFE and request the base tariff be restored. It is not instantaneous, and the underlying arithmetic still has to be satisfied first.
The practical consequence for anyone underwriting a Cabo property is that this is not a cost that can be managed reactively within a season. It is either designed out in advance or it is carried for a year.
The absentee owner’s version of the problem
A villa that is occupied intermittently by its owner and a villa that runs a full rental calendar are two different electrical loads, and the second one is not obviously worse. Sometimes it is better, because it is supervised.
The failure modes we see are consistent and mostly behavioural rather than mechanical.
Guests set thermostats to eighteen or nineteen degrees on arrival and leave them there, in a building designed to be comfortable at twenty-four. Terrace doors stand open with the air conditioning running, which in Cabo humidity converts an air handler into a dehumidifier running continuously against an infinite load. Unoccupied bedrooms cool alongside occupied ones because nothing zones them off. Pool equipment runs on a schedule set at commissioning and never revisited against actual use. Mini-split filters and coils go unserviced, and a fouled coil pulls materially more power to deliver the same cooling.
None of those is a large individual number. Together, across a summer, they are the difference between an average that stays under the limit and one that does not.
The vacancy side has its own quirk. From 2026, CFE bills a minimum of 25 kWh per month on domestic service regardless of what the meter records, so a villa standing empty does not bill zero. In practice the floor is academic for a house this size — standby loads, pool circulation, refrigeration, and dehumidification in a closed building keep real consumption well above it. That last item deserves attention on its own terms, because a closed coastal house without air movement is a maintenance problem before it is an electricity problem.
What actually moves the number
The interventions that work are unglamorous and mostly involve removing decisions from guests rather than asking them to make better ones.
Thermostat setpoint floors, configured at the equipment rather than requested in the house manual, are the single largest lever. Door and window contacts that cut the air handler in a zone when a terrace door opens are standard in hotel construction and rare in private villas, and they address the largest single waste channel in a Cabo house. Zoning so that unoccupied wings are not conditioned matters more in a six-bedroom villa booked by a party of four than most owners assume. Pool pump scheduling reviewed against actual occupancy rather than left at the installer’s default is close to free. Scheduled coil and filter service on every mini-split, on a real interval, protects both the consumption line and the equipment life.
Above all of it sits monitoring. The trailing average is published on every receipt, which means the approach to the limit is visible months before the limit is crossed. A property whose consumption average is reviewed monthly is a property where the decision is still available. A property whose bills are filed unread is one where the decision gets made by default, and then holds for a year.
Our team reviews the tariff class and trailing average on the CFE account for every Mexican property we operate, as part of the same monthly cycle that covers the rest of the operating stack.
Solar, considered honestly
Los Cabos has excellent solar resource, and net metering with CFE nets injected generation against consumption, so a system large enough to hold net consumption below the limit does address the classification directly.
Two caveats belong alongside that.
The minimum monthly billing floor still applies regardless of net position, so a system does not take the account to zero. And the sizing question is genuinely property-specific — it depends on roof and terrace area, shading, the actual consumption profile, and how the house is operated, which is the same variable everything else in this briefing turns on. Public payback estimates for Mexican residential solar circulate widely and are built on assumptions that may have nothing to do with a particular villa. Anyone considering it should get a site-specific proposal from a licensed installer and have it modelled against their own twelve-month consumption record rather than against a published average.
Reducing consumption and installing generation are complements here, not alternatives. Generation sized against an uncontrolled load is an expensive way to avoid a cheaper fix.
The question to ask at closing
Buyers routinely ask about property tax, trust fees, and homeowners association dues before closing, and routinely do not ask about the electricity account.
The useful question is what tariff class the service currently carries and what the trailing twelve-month consumption average is. Both are on the seller’s receipt. A property already classified in DAC comes with that classification attached and with an average that has to be worked down before it can be reversed, which is a real cost in the first year of ownership and one that is entirely knowable in advance.
There is a second question that circulates in Cabo buying circles and deserves careful handling. Some buyers report having asked CFE to re-baseline consumption history at change of ownership by presenting the fideicomiso or escritura. This is not published CFE policy. The standard position is that consumption history follows the meter rather than the account holder, and the reported outcomes are not consistent. It costs nothing to ask at closing. It is not a basis for an underwriting assumption, and a purchase model that depends on it is a model with an unpriced risk in it.
Why this belongs in the model
In the operating stack for a staffed Cabo villa, electricity is not the largest line. Staffing and capital reserve are both bigger.
It is, however, the line with the widest gap between what a first-year owner budgets and what arrives, and it is the only one where a twelve-month lag sits between cause and consequence. An owner who gets staffing wrong finds out in the first payroll cycle and can correct it. An owner who gets this wrong finds out in month thirteen and carries it through month twenty-four.
Which is why it belongs in the underwriting conversation before purchase rather than in the operating review afterward. The full picture of how this line sits against the rest of the operating stack is set out in our briefing on what a Los Cabos villa actually earns, and the seasonal pattern that drives the summer consumption spike is covered in our analysis of the Cabo shoulder season.
Owners who want the tariff class and consumption history on their own Cabo property reviewed can talk to our team about Los Cabos property management.
Tariff figures in this briefing reflect the charges published for January 2026 and were current as of August 2026. CFE applies a monthly adjustment factor to domestic rates and revises the published schedule periodically, so all figures should be confirmed against a current receipt or the official published schedule before use. Consumption examples are illustrative and are not a forecast, projection, or guarantee of what any property, including any property under Virestia management, will consume or be billed.
Nothing here is tax, legal, engineering, or investment advice, and it should not be relied on as a substitute for it. Tariff classification, reclassification procedure, and interconnection requirements are determined by CFE and applicable regulation. For a specific property, confirm the position with CFE directly and take advice from appropriately qualified local professionals.
