The TE8M electric truck is a 6x4 battery-electric tractor that Uzbek fleets are adopting for drayage, and Uzbekistan is reforming its power sector and rolling out more renewable capacity, which creates a new opportunity for fleet operators: the electric truck as a mobile energy asset. The TE8M electric tractor spends much of its life parked between drayage shifts, and during those hours its 400 kWh pack can support vehicle-to-grid, or V2G, services. This guide explains V2G basics, how a Tashkent depot becomes an energy asset, the tariff arbitrage math, the battery degradation cost versus revenue, and a pilot roadmap for Uzbek fleets.
Vehicle-to-grid means the truck's battery can discharge back to the grid or to a local microgrid through a bidirectional charger, instead of only drawing power. The TE8M is a 6x4 electric tractor with a 400 kWh CATL LFP pack and a 400 kW LvKong motor, GCW 49t and a 280 km range. With a bidirectional charger at the depot, the parked tractor can sell peak shaving, frequency response, or arbitrage energy, then recharge before its next duty cycle. LFP chemistry is well suited to this because it tolerates high cycle counts, and the 8-year / 4,500-cycle battery warranty already assumes intense use.
V2G is not free energy; it is the monetization of idle battery hours. The art is capturing revenue without eroding the pack faster than the payment covers. We model every V2G proposal against the truck's real duty profile, because a tractor that sits parked only four hours a day cannot export the same volume as one parked overnight, and over-promising export is the fastest way to break the morning shift.
A Tashkent logistics depot with ten TE8M tractors holds 4,000 kWh of dispatchable storage when the trucks are parked, enough to shave a meaningful slice of the evening peak for a small industrial zone. Because Uzbek peak tariffs and evening demand are rising with electrification and heat, a depot that exports during the 18:00 to 21:00 peak and recharges during the 02:00 to 05:00 trough can capture a spread on every kilowatt-hour moved. The depot becomes a participant in the energy market rather than a passive consumer.
| Hour band | Action | Tariff role |
|---|---|---|
| 02:00 to 05:00 | Recharge trucks | Off-peak buy |
| 08:00 to 17:00 | Normal duty | Consumption |
| 18:00 to 21:00 | Export V2G | Peak sell |
The Uzbekistan EV truck market is early but policy-friendly, and pilot aggregation frameworks are emerging that let a single depot register as a virtual power plant. Early movers who build the depot right lock in the simplest path to participation, because the first aggregators to sign depots will prioritize sites that already have certified bidirectional chargers and clean telemetry rather than those that need retrofitting.
The core V2G equation is simple: revenue equals the volume exported times the peak-to-trough price spread, minus round-trip losses and degradation. Suppose the Tashkent off-peak rate is 0.04 USD per kWh and the evening peak the depot can serve is 0.11 USD per kWh, a spread of 0.07 USD. If one TE8M exports 150 kWh on a peak evening, that is 10.50 USD per truck per day, or roughly 3,100 USD per truck per year, before aggregator fees. Across ten tractors, the depot earns about 31,000 USD annually from energy it was not using anyway.
| Variable | Value | Note |
|---|---|---|
| Off-peak buy | 0.04 USD/kWh | Trough rate |
| Peak sell | 0.11 USD/kWh | Evening export |
| Spread | 0.07 USD/kWh | Gross margin |
| Export per truck | 150 kWh | Leaves shift margin |
| Annual per truck | ~3,100 USD | Less fees and loss |
Round-trip efficiency of a good bidirectional system is about 85% to 90%, so the effective spread after losses is closer to 0.06 USD per kWh. The arbitrage still clears comfortably as long as the depot does not pay a demand penalty for the export connection. Operators should also confirm that the peak window the aggregator pays for matches the truck's actual parked window, because exporting during a declared peak the truck is not present for is a contract breach.
The honest counterweight is battery wear. Each V2G cycle adds to the pack's count, and although LFP is robust, extra cycles are not free. A conservative degradation cost is 0.01 to 0.02 USD per kWh exported, covering the small acceleration of capacity loss and the value of the lost cycle headroom. Against the 0.06 USD net spread, the truck still nets 0.04 to 0.05 USD per kWh, so the revenue comfortably exceeds the wear. The 4,500-cycle warranty gives ample headroom: a depot running one V2G cycle per parked day adds about 300 cycles per year, leaving margin for years of combined duty and export.
The conclusion for Uzbek operators is that V2G is worth doing, but only with discipline. The TE8M electric tractor earns more as a parked asset than most fleets realize, provided the export is bounded and monitored, and the fleet portal makes that bounding a one-click policy rather than a daily manual task.
We recommend a staged rollout. Phase one installs one bidirectional charger and runs a single TE8M in export mode for 90 days, measuring real spread, losses, and cycle impact. Phase two extends to a depot cluster of five to ten trucks under an aggregator contract. Phase three ties the depot to on-site solar so that midday surplus charges the fleet and evening export compounds the saving. Throughout, the export cap protects the morning drayage range, so the primary job of the tractor is never compromised by its side business as a battery.
V2G revenue is only real if the rules allow it, and Uzbekistan's framework is still forming. The first practical step is confirming that the depot's connection agreement permits export, because some industrial tariffs forbid feeding energy back to the grid without a separate license. We help buyers read the connection contract and, where needed, apply for the distributed-storage permission before the charger is installed, so the depot is legal to export from day one rather than after a costly retrofit that interrupts the transport duty.
The second step is choosing an aggregator, the intermediary that pools many depots into a resource the grid operator will accept. Early Uzbek aggregators vary in how quickly they pay and how strictly they meter, so we advise a pilot with one truck and one aggregator before committing the whole fleet. The contract should specify the export window, the measurement method, and the penalty if the truck is unavailable because of transport duty. A clean contract plus a certified bidirectional charger is what turns the TE8M electric tractor from a transport asset that merely sits idle into a registered participant in the Uzbek energy transition, earning while it waits and protecting the morning drayage range through a hard export cap.
Done this way, the TE8M turns a Tashkent depot into a revenue-generating node on the Uzbek grid, and the 8-year / 4,500-cycle battery warranty is sized to absorb the extra cycling without threatening the core transport warranty.
