Why is my NV Energy bill so high this summer?

Your bill is high for two reasons and there are only two. How many kilowatt hours you used, and what each one costs. In a Las Vegas summer the first number is very large, because cooling runs most of the day and most of the night. The second number is fixed, public and easy to check. Here is the arithmetic, taken off NV Energy's own rate sheet.

What a kilowatt hour costs on the standard residential plan

Most Las Vegas houses are on Schedule RS, residential single family. NV Energy's rate schedule effective July 1 2026 sets it out line by line.

Two lines do almost all the work. The electric consumption rate of $0.11622 is what you are actually buying. The basic service charge of $18.00 is what you pay before you switch anything on. We take the whole schedule apart, including the optional plans, in what a Las Vegas home actually pays per kilowatt hour.

One note for anyone checking our work against the same sheet. The worked example NV Energy prints on it uses a basic service charge of $12.50, which is not the $18.00 the same sheet lists for Schedule RS. Every figure below uses the $18.00 from the schedule itself.

Run your own usage through it

The method on that sheet is simple enough to do on a phone.

1. Take your kilowatt hours for the month and multiply by $0.12054. That is every per kilowatt hour line except the universal energy charge.
2. Add the $18.00 basic service charge. That is your subtotal.
3. Add 5 percent of the subtotal for the Clark County local government fee.
4. Add your kilowatt hours times $0.00039 for the universal energy charge.

Find your kilowatt hours on the usage graph on page one of your bill and read across. If the total you get is close to what you were charged, nothing has gone wrong with your account. You used that much power. The rate did not move.

Four things to check on page one before you call anyone

1. Bill days. A 33 day period costs more than a 29 day one for the same house. The meter read dates are printed on the statement, and a long month after a short one looks like a spike that is not one.
2. The usage graph. NV Energy prints this month, last month and the same months a year ago. Compare August to August, never August to April.
3. Average kilowatt hours per day. This is the honest comparison between two months of different lengths, and it is printed for you.
4. The rate schedule name. Look for RS, RM, LRS or a time of use code such as ORS-TOU. A single family house billed on a schedule meant for something else is the one situation where the bill really is wrong, and it is the situation behind the refunds below.

What this summer actually did to the usage side

Heat here is a measurement, not a mood. The National Oceanic and Atmospheric Administration's daily records for Harry Reid International Airport, June 1 to September 16 2026, show:

• 85 days at 100 F or above
• 23 days at 110 F or above
• a high of 115 F on August 1
• 19 days in a row at 108 F or above, July 22 to August 9
• 24 nights in a row when the low never fell below 85 F, July 19 to August 11

The last line is the one that lands on your bill. An air conditioner in this valley is supposed to get a rest after dark. For 24 nights it did not get one, so it ran through the night and started the next afternoon already behind. If your house has two units, both were running, and two compressors draw roughly twice the power of one.

That is why a bill you have known to within $20 for years can land at a number you do not recognise. Nothing was added to your account. The weather added hours to your compressor.

Three things that are not your imagination

Some people really were billed wrong. FOX5 Las Vegas reported on January 20 2026 that NV Energy proposed more than $63 million in refunds, including interest, to active customers affected by a billing error dating back to 2002, in which multi family residences were classified as single family. The proposal went to the Public Utilities Commission of Nevada. If you live in a condominium, a townhouse or a duplex, that is worth reading about in the overcharge story.

A new line is coming. NV Energy plans to break a daily demand component out of the energy rate for southern Nevada residential customers, priced at $0.14 per kW of your highest 15 minutes of use in a day. NV Energy's own page says it appears on bills starting in January 2027 and puts the average customer's peak near 3.5 kW, about $0.49 a day. It is scheduled for January 1 2027, under appeal: a Las Vegas judge denied the attorney general's petition against it in May 2026 and Attorney General Aaron Ford said he would appeal to the Nevada Supreme Court. We keep the demand charge page current.

The evening rate on the optional plan is not the rate you think. If you moved to the optional time of use schedule, ORS-TOU, your summer evenings are priced separately. On NV Energy's time of use plan, summer on peak is $0.47155 per kWh from 6:01 pm to 9 pm daily, June 1 through September 30, against $0.07305 off peak. That is the same rate schedule, and the spread is the reason a time of use bill can look nothing like a neighbour's. NV Energy also publishes a first year guarantee on that schedule: after a year it compares what you paid under time of use against the standard residential rate and credits the difference if time of use cost more.

What actually changes the number

Only three things move a Las Vegas summer bill, and it is worth being honest about the size of each.

Using less. Real, slow and limited. Two degrees on the thermostat works, and most people here have tried it.

Moving use out of the expensive hours. This only pays if you are on a time of use schedule today, and it will matter to everyone once the daily demand component starts. Spreading the dryer, the oven and the car charger across the evening instead of stacking them into the same 15 minutes is the whole technique.

Making some of your own power. If you already have panels and the bill still looks like this, start with how to read your bill once you have solar, because the answer is usually on the statement. Otherwise, this is the only one of the three that changes the energy charge at scale, because it reduces the kilowatt hours NV Energy delivers to you. It does not touch the $18.00 basic service charge or the local government fee, and anybody who tells you it will is selling you something. What it can do is take the biggest line on the page and cut it.

We put the numbers on both sides of that question in is solar worth it in Las Vegas, and the evening half of it in why a battery pays for itself between 6 and 9 pm. Whether the arithmetic works on your roof depends on your usage, your roof and your shading, and the only way to know is to run your last twelve bills against your actual roof. That is what our assessment is, it costs nothing, and if your roof is a poor candidate we will tell you that instead.
