ForgeAsset / Supercharger ROI / Nebraska
Tesla Supercharger ROI in Nebraska
Nebraska is the only all-public-power state in the country — no investor-owned utility sells retail electricity anywhere in it. ForgeAsset models both metro systems: Omaha Public Power District's Rate 231, one of the cheapest demand rates in the covered set, and Lincoln Electric System's LLP, whose 3-cent energy is the library's cheapest against a facilities-heavy demand charge. A 3¢/kWh charging excise is enacted and arrives in January 2028.
What makes Nebraska economics distinct
Public power prices without a shareholder margin
OPPD bills about 7 cents bundled energy and $9.22 per kW — the demand rate is roughly a quarter of what the heaviest covered jurisdictions charge. Board-approved rate books replace commission dockets, which means annual adjustments and published resolutions rather than multi-year rate cases.
Omaha and Lincoln price the same load very differently
Lincoln's LLP rate carries energy near 3 cents — the cheapest in the covered set — but stacks $27 per kW of facilities-weighted demand, so a Lincoln site models at roughly twice an Omaha site's electricity cost at default utilization. The split is filed reality across two rate books, and the model prices each city on its own.
The 2028 charging excise is enacted, not proposed
LB 1317 levies 3 cents per kWh on public charging beginning January 1, 2028. The model includes it from model year 3 for a 2026 opening — about $24,000 per year at default volumes once in force — rather than surprising the owner mid-hold. Collection guidance from the Department of Revenue is still unwritten, a stated open item.
A ratchet that does nothing to a steady peak
Both metro schedules carry seasonal demand ratchets — 85%/60% lookbacks at OPPD, 65% summer at LES. For a charging site that draws its full hardware peak every month, every lookback term is at or below the current month and the ratchet never binds; the model prices that exactly rather than padding for it.
Utilities and tariffs modeled in Nebraska
| Utility & tariff | Energy | Demand |
|---|---|---|
| OPPD Rate 231 | 7.1¢/kWh flat | $9.22/kW of monthly peak |
| Lincoln Electric System LLP | 3.1¢/kWh flat | $26.99/kW of monthly peak |

Nebraska tax profile
- Sales tax on hardware: 7%
- Business personal property tax: 2.04% of equipment value (example rate)
- Clean-fuels credit: no program
- Per-kWh charging excise: 3.0¢/kWh from model year 3
Nebraska tax defaults applied: no clean-fuels credit program exists in Nebraska (the LCFS revenue line is $0), LLC costs use the $25 biennial report, and sales tax defaults to Omaha's 7% combined rate (Lincoln runs 7.25% — the field is editable). Business personal property uses the Douglas County levy of about 2% on net book value, which declines to zero as the equipment depreciates out — the model's flat rate overstates later years. Nebraska's 3¢/kWh charging excise takes effect January 2028 and is included from model year 3, assuming a 2026 opening; the mapping is editable in Step 3. At default volumes the excise is on the order of $24,000 per year once in force.
Nebraska programs and incentives
NEVI (federal, NDOT-administered)
Roughly $30 million over five years for corridor DC fast charging along I-80; the Nebraska Department of Transportation administers rounds.
Nebraska charging market
Nebraska carries roughly 11 Supercharger stations, dominated by the I-80 corridor from Omaha through Lincoln, Grand Island, and North Platte. OPPD serves the Omaha metro and Lincoln Electric System the capital; both are modeled. OPPD has filed a restructuring of its demand schedules for 2027 with rates set by a December 2026 board vote — the library re-derives after the vote.
Nebraska Supercharger ROI — questions
- Does Nebraska charge a demand charge on EV charging?
- Yes — OPPD bills about $9.22 per kW bundled and Lincoln Electric System about $27 per kW (facilities-weighted), each on the month's own peak. The seasonal ratchet clauses in both books resolve to the current month for a site with a steady billed peak, and the model prices them exactly.
- When does Nebraska's charging tax start?
- January 1, 2028, at 3 cents per kWh on public charging (LB 1317, enacted). The model includes it from that date — about $24,000 per year at default volumes — with the start year editable as the assumed opening year moves.
- Who sets electricity rates in Nebraska?
- Public power boards — Nebraska has no investor-owned electric utilities. OPPD and LES adopt rates by board resolution annually, which the model treats like any filed tariff: rates carry their adoption dates, and the library re-derives when a new book lands.
