WAIRE Compliance: How Electric Trucks Offset Mitigation Fees
By Kevin Prince, Vice President, Sales – Truck, North America | 8-minute read
For warehouse operators in the South Coast Air Quality Management District (SCAQMD), the Warehouse Actions and Investments to Reduce Emissions (WAIRE) program is no longer a future problem, it’s here.
In an anonymized seven-year analysis carried out by Zenobē’s commercial fleets team, the results show how avoided WAIRE mitigation fees, fuel savings and available incentives can turn a charging deployment from a compliance cost into a net saving.
The measured phase-in of the regulation of WAIRE is now complete, and every qualifying site in the South Coast Air Quality Management District is now carrying an annual obligation measured in what’s called WAIRE points.
Most of the conversation about WAIRE focuses on what it costs. At Zenobē, we wanted to look at it from the opposite direction: if an operator is pursuing the deployment of electric trucks and charging infrastructure to combat rising fuel costs anyway, how much of that investment does WAIRE help to recover? To find out, we modeled a real deployment for a logistics operator with a large warehouse in Orange County, California. Details have been anonymized and figures rounded, but the method and the conclusions are the ones we would apply to any site.
How the WAIRE Points System works
Rule 2305 applies to owners and operators of warehouses of at least 100,000 square feet that are served by Class 2b to 8 trucks. Each year, a site’s WAIRE Points Compliance Obligation (WPCO) is calculated from total truck traffic, which includes the operator’s own fleet plus any third-party vendor or delivery fleet that enters the site. Trips are converted into Weighted Annual Truck Trips (WATTs), with tractors counted at 2.5 times the weight of smaller straight trucks, and the result is multiplied by a stringency factor of 0.0025 points per WATT. Setting aside the new acronyms and arbitrary math, the basic conclusion is that the more truck traffic a site has, the more “points” you need to offset to remain in compliance.
An operator can meet the obligation in two ways. The first is to pay a mitigation fee of $1,000 per point. The second is to earn points through actions from the WAIRE Menu, which includes among other actions, acquiring or leasing zero-emission or near-zero-emission trucks, hosting visits from those trucks, installing and using on-site charging infrastructure, installing solar, etc.
$1,000
Because the fee is fixed at $1,000 per point, every point an operator earns through its own actions is worth a known amount: the fee it no longer has to pay.

That is the key to the analysis below. WAIRE puts a dollar value on emissions reductions, so they count in the financial case for electrification rather than sitting outside it.
The scenario we modelled
The operator runs a Southern California facility that is subject to Rule 2305 and was considering replacing two diesel Class 8 tractors with battery-electric equivalents. The assumptions were deliberately ordinary:
- Two battery-electric Class 8 tractors, each covering about 35,000 miles a year.
- A single 200 kW charging cabinet feeding two dispensers on site, with an alternative design sized to expand to as many as six dispensers later. The trucks domicile at the warehouse overnight so the charging design is suitable for overnight off-peak charging, further driving operational fuel savings.
- A turnkey delivery model in which the infrastructure is designed, built, financed and operated for a seven-year term, with the trucks leased, so that no upfront capital is required.
- A $120,000 voucher per truck from the Clean Fuel Rewards program, reflected in the lease.
- Electricity priced at a mid-peak public utility rate of around 9 cents per kWh, with both diesel and electricity prices assumed to rise by roughly 3% a year.
The analysis also includes current diesel truck operating expenses, including the operator’s existing lease costs, per-mile charges, maintenance, fuel and licensing. The electric case included the full charging service and truck lease fees, electricity, maintenance and, crucially, the avoided WAIRE mitigation fees.
Results of analysis of diesel vs. electric truck ownership and operation
Monthly cost per truck: diesel vs. electric
| Monthly cost per truck | Approx. $ |
|---|---|
| Diesel tractor | 7,400 |
| Electric before WAIRE | 10,200 |
| Avoided WAIRE mitigation fees | (4,000) |
| Electric after WAIRE | 6,200 |
| Savings per truck per month | 1,200 (about 16%) |

Over seven years, the electric option came out roughly $155,000 ahead of continuing with diesel in today’s money, even after paying for the charging infrastructure, the truck leases and every operating cost. Over the same period the operator would spend around $570,000 less on fuel and about $30,000 less on maintenance and avoid roughly 125 tons of tailpipe CO₂ emissions each year.

Where the saving really comes from
It would be easy to read that headline and conclude that electric trucks simply pay for themselves. The honest reading is more nuanced, and more useful.
Electric trucks deliver real operating savings as lower fuel and maintenance costs recover a meaningful share of the investment on their own. When fuel and maintenance savings alone do not cover the cost of the infrastructure and the EV trucks, WAIRE can be the swing factor. Avoiding mitigation fees the operator would otherwise pay moved the electric option from about $240,000 behind diesel to about $155,000 ahead on an NPV basis.
That is not a weakness of the analysis. It is the point of it. Under Rule 2305 an operator with a compliance gap will pay for that gap one way or another: either as a mitigation fee that buys nothing for the business, or as an investment that earns points and also produces operating savings and a hedge against unpredictable diesel prices. The question for each site is how large the gap is and how much of it can be closed by actions the business would take anyway.
In this case, we capped the value of WAIRE points at 90 points a year, approximately the site’s projected annual compliance gap, which is $90,000 a year at the $1,000 fee. A site can only avoid fees it would otherwise have paid, so surplus points earn nothing in the model, and the realized value in any year is limited to the lesser of the points generated and the site’s obligation. In other words, a site with a smaller gap would see a smaller benefit, and a site with a larger one would see more.
Stacking the incentives
The case above counts only a state vehicle voucher. It does not include any infrastructure funding (e.g. EnergIIZE) or the new WAIRE Mitigation Program, which South Coast AQMD set up to recycle the fees paid under Rule 2305 into incentives for zero-emission projects around warehouses.
For the first year of the program, roughly $73 million is available for new zero-emission Class 4 to 8 trucks, off-road yard trucks, and charging and hydrogen fueling infrastructure. Funding is allocated by Source Receptor Area and awarded on a first-come, first-served basis. The published caps are $120,000 per battery-electric Class 8 truck and $300 per kW of charging output, and total incentives from all sources cannot exceed 85% of eligible cost.
Stacking these program funds is not automatic. Each has its own caps, eligibility rules and timing, and the district has acknowledged that stacking can be limited when solicitation windows do not line up. The infrastructure rules also include requirements such as public accessibility and the use of a skilled and trained workforce, and at least half of an infrastructure award must go towards equipment. Those requirements must be tested against each site’s design before an application is made. But for operators who can meet them, the combined effect is a lower net cost of electrification, and therefore an even stronger case than the one shown above.

Why turnkey fleet electrification delivery matters for the math
A fleet electrification project is not just a vehicle purchase. It involves utility engagement, design, permitting, construction, commissioning, charge management and years of operation. Each of those carries cost and schedule risk, and under WAIRE the schedule matters directly, because points can only be earned once actions are completed and documented.
In the analysis, the delivery plan allowed for 12 weeks after the first utility engagement, assuming a worst case for energization. Putting design, build, financing and operation with a single partner, and structuring payments as a monthly service fee rather than upfront capital, also keeps the electric option comparable with the diesel lease it replaces. That comparison is what makes the total cost of ownership analysis meaningful to a finance team.
Zenobē has the experience to deliver on these timelines because we have done this at scale before: we have energized more than 3,500 electric trucks and buses globally. That experience has taught us that the pace of energizing charging infrastructure is set by utility interconnection and site readiness, not by construction capacity or other constraints.
What to consider before applying this analysis to your own site
The figures above belong to one site. The method transfers, but the answer will not. Before relying on a similar analysis, an operator should work through the following.
Your real WPCO
Calculate your WATTs from actual truck trips, apply the correct stringency for your size bracket and year, and establish how much of the obligation is likely to recur annually rather than reflecting one-off effects.
How many WAIRE points your actions would earn
Check the current WAIRE Menu and implementation guidelines rather than older published values and confirm that your records will meet the documentation requirements.
Your electricity tariff
Rates vary widely by utility, rate schedule and charging window, and demand charges can change the picture considerably. A low assumed rate flatters the result.
Your fuel assumptions
Diesel and electricity price escalation drive a large share of the savings. Test the case with flatter price assumptions.
Which incentives you qualify for
Confirm eligibility, caps and deadlines for HVIP, the WAIRE Mitigation Program and any utility make-ready programs, and check how they combine.
Operational fit
Confirm that route lengths, dwell times and parking layout work for the trucks and chargers you intend to use.
The bottom line - under Rule 2305, the cost of doing nothing is not zero
An operator that does not earn points through its own actions pays $1,000 for every point it falls short. In the case we modeled, redirecting that money into two electric trucks and the charging to support them produced a net advantage of around $155,000 over seven years, before any WAIRE Mitigation Program funding, with a materially lower fuel bill and a cleaner fleet along the way.
The result depends on the size of the compliance gap, and it should be tested site by site. If you operate a warehouse in the South Coast Air Basin and want to know where you stand, we can help you model your obligation, compare the fee route with an electrification route, and build a delivery plan that fits your operation.
