An electric truck is not just a consumer of electricity; when parked, its large CATL LFP pack can become a storage asset for the grid. Vehicle-to-grid, or V2G, turns a parked TE9L electric tractor fleet into a virtual power plant. For operators in Colombia's industrial corridors, that capability opens a new revenue and savings line that diesel never offered, and it reframes the depot as an energy node rather than a cost sink.
Most trucks sit parked far longer than they drive. A regional tractor might roll eight hours and rest sixteen, and during those sixteen hours its battery is a dormant asset worth tens of kilowatt-hours. V2G wakes that asset by letting energy flow back to the depot or grid on command. The catch is battery life, but CATL LFP is unusually tolerant of the shallow, frequent cycles that grid service demands, which is why this opportunity is real today rather than theoretical.
Bidirectional charging lets energy flow from the truck battery back to the depot or grid. During peak tariff hours the fleet discharges to shave demand charges; during off-peak and solar-rich hours it charges cheaply. The trucks are almost always parked longer than they drive, so the idle window is where the value lives, and software can manage it without a human touching a cable.
The key insight is that the truck does not need to be full to be useful to the grid. Even a partially charged pack arriving at the depot at 60 percent state-of-charge can still discharge a useful slice during the evening peak before recharging overnight. This means V2G works with normal operations rather than against them, and drivers never return to a truck too empty to run the next shift because the system respects a hard reserve. Operators in Colombia quickly learn to trust the automation, because the software balances grid service against drive readiness every few seconds, something no manual regime could match across fifty vehicles.
Commercial electricity bills in Colombia are dominated by peak-demand penalties, not just energy. A depot drawing 500 kW at 6 pm pays for that spike all month. A V2G fleet can clip the spike and turn a liability into a saving, often paying back the bidirectional charger faster than the vehicles alone would.
The business case rests on battery life. CATL LFP is uniquely suited because it tolerates shallow, frequent cycles. With an 8-year / 4500-cycle warranty, a fleet can use hundreds of those cycles for grid services without touching the depth that matters for drive range, and the pack barely notices.
| Factor | Without V2G | With V2G |
|---|---|---|
| Daily drive cycles | 1 | 1 |
| Grid service cycles | 0 | 1 to 2 shallow |
| Warranty headroom | Large | Still within 4500 cycles |
| Net energy cost | Baseline | 10 to 30 percent lower |
Keeping V2G discharges shallow (say 20 to 30 percent depth) preserves the pack while capturing most of the arbitrage value. The TE9L's management system can enforce these limits automatically, so drivers never return to a truck too empty to work.
Aggregate fifty tractors and you have tens of megawatt-hours of dispatchable storage. To a utility or aggregator, that is a virtual power plant. Operators can monetize the parked fleet in several ways that compound the savings from peak shaving.
Data and metering are the unglamorous foundation of any V2G program. Without accurate per-truck energy accounting, operators cannot prove the savings, defend the warranty position, or invoice the aggregator with confidence. The good news is that the TE9L already reports state-of-charge, cycle count and temperature, so the depot layer only needs to aggregate those streams into a single dashboard that shows net grid position hour by hour.
Colombian operators who invest in this data layer find the V2G business case becomes self-evident rather than theoretical, because every peso of saving is traced to a specific vehicle and hour. That traceability also reassures the OEM that the pack is being used within agreed limits, which keeps the warranty clean. The depot that measures well is the depot that monetizes well, and the gap between a V2G pilot that fails and one that scales is almost always the quality of the underlying energy data.
V2G is a depot project, not a truck project, so the rollout is mostly about chargers and software. The staged plan below keeps risk low while proving the concept on a handful of vehicles first.
| Step | Action |
|---|---|
| 1 | Install bidirectional CCS2 chargers rated for fleet power |
| 2 | Deploy energy-management software with tariff signals |
| 3 | Set V2G depth and state-of-charge floors per truck |
| 4 | Pilot on 5 to 10 tractors before scaling |
| 5 | Negotiate aggregator contract once baseline is proven |
Risk and Contract Structure
V2G introduces new risks that a plain charging deployment does not, and they should be contracted away before the first bidirectional charger is energized. The main exposure is battery wear from grid service, which is why shallow depth limits and clear state-of-charge floors must be written into both the energy contract and the vehicle warranty conversation.
| Risk | Mitigation |
|---|---|
| Excess pack wear | Cap V2G depth at 20 to 30 percent |
| Grid outage during discharge | Keep SOC floor for drive duty |
| Aggregator default | Contract minimum monthly payment |
| Warranty dispute | Document V2G limits with OEM |
Done carefully, V2G is low risk because the LFP pack has the cycle headroom to absorb it, and the savings are contractually locked rather than hoped for. Colombian operators who treat the battery as a managed asset, not a fragile component, capture a revenue line their diesel rivals physically cannot access, turning the depot into a small but steady power plant that pays down the electric truck faster than driving alone ever could.
V2G turns the electric truck from a cost center into a flexible energy asset. For Colombian fleets with predictable parking and volatile tariffs, the LFP cycle headroom makes the math work without harming the vehicle. The depot of the future is not just charged; it is a power plant on wheels, and the operators who build it now will own a structural cost advantage their diesel competitors cannot copy.
