The NV Energy demand charge bills $0.14 per kilowatt of your highest 15-minute draw every day, starting January 1, 2027 for Southern Nevada homes. Two appeals are pending at the Nevada Supreme Court, with no ruling reported as of October 13, 2026. Here is how it works, who pays most, and what actually lowers it.
Quick Answer
NV Energy's demand charge bills $0.14 per kW of your highest 15-minute draw each day, per The Nevada Independent — a demand line of about $0.49 a day for a typical home, per NV Energy. It starts January 1, 2027. As of October 13, 2026, two Nevada Supreme Court appeals are pending, with no ruling reported.
The 30-Second Version
Date: January 1, 2027 for Southern Nevada residential customers, per NV Energy's Daily Demand fact sheet — after two delays (originally April 1, 2026, then October 1, 2026).
The math: your single highest 15-minute peak each day, in kilowatts, × $0.14, × the days in the bill. A typical home's demand line lands near $15 a month. Solar homes pay it in full, because net-metering credits don't touch it.
The fix: keep big loads from stacking, or let a battery with enough continuous output cover the stack. The same battery is what keeps the house running when the grid goes down.
What Changed Since the August Update
A demand line of about $0.49 a day for a typical household, according to NV Energy's Daily Demand fact sheet — roughly $15 over a 30-day bill. That figure matches The Nevada Independent's reporting that the average Southern Nevada customer peaks near 3.5 kW and the rate is $0.14 per kW per day.
Your number depends on your peak, not your usage. The table runs the arithmetic at the rate as reported; it is an illustration, not a bill estimate.
| Your daily peak (15-min) | Per day at $0.14/kW | 30-day bill | Typical cause |
|---|---|---|---|
| 3.5 kW | $0.49 | $14.70 | Average home, per NV Energy |
| 6 kW | $0.84 | $25.20 | AC compressor + dryer together |
| 10 kW | $1.40 | $42.00 | AC + Level 2 EV charger together |
| 14 kW | $1.96 | $58.80 | AC + EV charger + pool pump + dryer |

Added Cost, Average Solar Home
About $12, per The Nevada Independent; about $20, per the Las Vegas Review-Journal (Sept. 2025).
It is a charge of $0.14 per kilowatt on the single highest 15-minute stretch of power your home draws each day, per The Nevada Independent, billed as its own line next to the energy you use. Energy (kWh) is how much electricity you used; demand (kW) is how hard you pulled at once.
If your home pulled 6 kW for fifteen minutes at 7 p.m. on a Tuesday — air conditioner, dryer and EV charger all running — that 6 kW sets Tuesday's charge: $0.84 (6 × $0.14). The rest of the day can be quiet. The peak is what's billed, and the clock resets at midnight.
Two homes can use the same kilowatt-hours in a month and pay very different demand charges, depending on whether they spread their loads or stacked them. NV Energy frames the charge as correcting a cost imbalance between solar and non-solar customers, which The Nevada Independent puts at roughly $50 million a year — the argument every regulatory and legal fight over this charge is actually about.
It starts January 1, 2027, per NV Energy's Daily Demand fact sheet, and as of October 13, 2026 two appeals against it sit at the Nevada Supreme Court with no ruling.
January is the third start date. April 1, 2026 was the original; NV Energy asked to move it to October 1, 2026; and on March 31, 2026 the Public Utilities Commission of Nevada pushed it to January.
Commissioners framed the second delay around refunds, not doubts about the charge. In the words of Commissioner Randy Brown, reported by the Nevada Current, NV Energy and the PUCN "are both prioritizing customer refunds over the implementation of the daily demand charge."
Two challengers took it to court, and both lost the first round within two days of each other:
The bureau's core argument, per the Review-Journal, is that a mandatory daily demand charge works like a mandatory time-of-use rate, which Nevada law does not allow for residential customers. Lawmakers had a chance to settle it outside court: on August 18, 2026 the Joint Interim Standing Committee on Growth and Infrastructure declined to advance a bill draft request from its chair, Assemblymember Howard Watts, to ban residential daily demand charges, per KTNV. The charge could take effect on schedule, be delayed again, or be struck down.
Every kilowatt you take off your daily peak saves $0.14 a day — about $4.20 on a 30-day bill — and the cheapest way to take it off is to stop big loads from running in the same 15 minutes. You are not using less; you are spreading it out.
A home that keeps its peak near the 3.5 kW average stays near the roughly $15-a-month typical figure. A home that routinely stacks AC and an EV charger can land near the 10 kW row in the table above — about $42 a month — without using a single extra kilowatt-hour.
A battery cuts the charge by covering the gap between what your home is drawing and what you let it pull from the grid, so the peak NV Energy measures stays capped. The specification that decides whether it works is continuous output in kilowatts, not storage in kilowatt-hours.
A large battery that can only discharge at 5 kW won't suppress a 9 kW peak. A 13.5 kWh battery that discharges at 11.5 kW will.
| System | Usable kWh | Continuous kW | Short-burst / motor start | Practical note |
|---|---|---|---|---|
| Tesla Powerwall 3 | 13.5 | 11.5 kW | 15.4 kW off-grid continuous (configurable) 185 LRA |
Highest single-unit continuous output of the three; covers AC + a Level 2 charger in one box. |
| FranklinWH aPower 2 | 15.0 | 10 kW | 15 kW for 10 s 185 A LRA |
Most storage per unit; slightly less continuous output than Powerwall 3. |
| Enphase IQ Battery 5P | 5.0 per unit | 3.84 kW per unit | 7.68 kW for 3 s up to 48 A LRA |
Modular; stack two to four units to approach a single Powerwall 3 or aPower 2. |
Specs per the manufacturers' datasheets: Tesla Powerwall 3 Datasheet (2025), FranklinWH aPower 2 Datasheet, Enphase IQ Battery 5P Datasheet (DSH-00010). LRA = locked-rotor amps, the start-up surge an air-conditioner compressor needs.
How to read the table: for a 3-bedroom Henderson home with central AC (a 5–6 kW compressor), a Level 2 EV charger (7–11.5 kW) and a pool pump, the question is whether the battery can carry those loads together for fifteen minutes. A single Powerwall 3 or aPower 2 generally can; a single 5P cannot. Households without a pool or EV need less; two EVs and a workshop need more. The honest sizing runs against your own NV Energy 15-minute interval data — which the new MyAccount daily-demand view now shows.
Yes — the 11.5 kW of continuous output that caps a daily peak, per Tesla's Powerwall 3 datasheet, is the same output that runs the house when the grid is down, as long as the system is installed with backup. One purchase does both jobs, and neither depends on the other.
Grid security became a federal question this year. On August 26, 2026 the President signed Executive Order 14421, declaring a national emergency over foreign-made equipment in the U.S. bulk-power system, per the Federal Register; the Department of Energy's request for information on implementing it closed October 9, 2026. A battery alone covers hours to about a day. Solar plus a battery recharges on each sunny day, so a correctly sized system keeps essential loads — refrigerator, lights, internet, fans — running day after day, as long as the sun recharges it. What the order covers, and what an extended outage could mean here, is in Could Nevada Lose Power for 18 Months? Executive Order 14421 and the Nevada grid.
Solar homes pay an estimated $12 to $20 more a month — about $12 per The Nevada Independent, about $20 per the Las Vegas Review-Journal — because net-metering credits offset the energy (kWh) part of the bill, not the demand (kW) part.
A home can export enough to zero out its energy charges and still owe the full daily peak charge.
At today's rate that is roughly $3,600 to $6,000 over 25 years, a cost most solar payback estimates written before 2026 never included.
Two situations change the answer, and both are about the house, not the battery. If you rent, the decision belongs to the owner; the four habits above are what you control.
If your roof is heavily shaded, solar won't recharge the battery well. The battery still shaves peaks by charging from the grid overnight, but its outage runtime shrinks to what's stored.
One honest caveat for everyone else: the Nevada Supreme Court could still strike the charge down. A battery justified only by this one charge rests on that ruling. A battery that also carries the house through an outage — and, for a solar home, stores midday production for the evening — earns its keep either way.

It is a daily charge of $0.14 per kilowatt of your single highest 15-minute power draw, added to every day of the bill, per The Nevada Independent. NV Energy's fact sheet puts a typical household at about $0.49 a day. It applies to Southern Nevada residential customers starting January 1, 2027.
January 1, 2027 for Southern Nevada customers, per NV Energy's Daily Demand fact sheet. It was originally approved for April 1, 2026, then moved to October 1, 2026, and on March 31, 2026 the PUCN pushed it to January. As of October 13, 2026, no further delay has been ordered.
Yes. As of October 13, 2026, two appeals are at the Nevada Supreme Court and neither has been decided. The Attorney General's Bureau of Consumer Protection appealed after Clark County District Judge Mary Kay Holthus denied its petition on May 26, 2026; Vote Solar appealed after a Carson City judge denied its separate petition the next day.
About $15 a month for a typical home's demand line, from NV Energy's roughly $0.49 a day. Your own number is your daily peak in kilowatts times $0.14 times the days in the bill: a home that peaks at 6 kW every day pays about $25 over 30 days, and one that peaks at 10 kW pays about $42.
Because net-metering credits offset the energy (kWh) part of the bill, not the demand (kW) part, so a solar home can zero out its energy charges and still owe the full daily peak charge. Estimates for an average solar home run from about $12 a month (The Nevada Independent) to about $20 (Las Vegas Review-Journal).
The one whose continuous output covers your loads running together. Per the manufacturers' datasheets, a Tesla Powerwall 3 delivers 11.5 kW continuous, a FranklinWH aPower 2 delivers 10 kW, and one Enphase IQ Battery 5P delivers 3.84 kW, so a home with central AC and a Level 2 EV charger usually needs either one large unit or several 5P units.
Keep your big loads from running in the same 15-minute window. Schedule EV charging overnight, pre-cool the house in the morning, run the pool pump and dryer when the air conditioner is not working hardest. Every kilowatt you take off your daily peak saves $0.14 a day, or about $4.20 over a 30-day bill.
They declined to. On August 18, 2026, the Nevada Legislature's Joint Interim Standing Committee on Growth and Infrastructure considered a bill draft request from its chair, Assemblymember Howard Watts, to ban daily demand charges for residential customers, and declined to advance it, per KTNV. That leaves the two Nevada Supreme Court appeals as the open path.
Yes. It has been delayed twice already, and the Nevada Supreme Court could reverse the approval, send it back, or let it stand; as of October 13, 2026 neither appeal has been decided. A battery bought only to beat this charge rests on that outcome. A battery that also carries a home through an outage does not.
