Tellus x Simtricity
V2G Pilot Project Proposal
January 2026
Dear Mark and Jack,
Thank you for the opportunity to present this proposal for Simtricity's V2G pilot project with Tellus Power.
Following our discussions and the meter we shipped to Jack in December, we're excited to move forward with the pilot as the first step toward a potential nationwide rollout across your dealership network.
Simtricity proposes a 3-month pilot to prove the commercial value of Tellus's bidirectional EV chargers. We will adapt our proven Flux battery control platform to dispatch V2G chargers on wholesale electricity markets via our existing Axle Energy integration.
What is V2G?
Vehicle-to-Grid (V2G) is bidirectional charging technology that allows electric vehicles to send power back to the grid, not just receive it. When parked, a V2G-connected vehicle becomes a mobile battery that can earn revenue by helping balance the electricity system — charging when power is cheap and abundant, discharging when it's expensive and scarce.
About Tellus Power
Tellus Power Group is a global leader in EV charging infrastructure, delivering scalable solutions across the USA, Europe, Asia Pacific, and the Middle East. With expertise in V2G technology and smart energy management, Tellus helps businesses, fleets, and infrastructure operators maximise efficiency and drive sustainability.
The Opportunity
Tellus sells bidirectional EV chargers to businesses with overnight fleet vehicles — delivery vans, company cars, service vehicles that sit parked for hours at a time. These chargers can aggregate into a "virtual battery" traded on wholesale electricity markets, generating revenue for fleet operators while vehicles are parked.
The key insight: Fleet vehicles spend most of their time parked. During those hours, their batteries can work for their owners — earning money instead of sitting idle.
How V2G Creates Value
The primary value of V2G comes from optimising your customer's site energy bills — not just from grid trading. Here's how the revenue stacks up:
1. Import Optimisation
Charge vehicles when electricity is cheap — overnight, during solar peaks, or when wholesale prices dip. This directly reduces the site's energy bills.
2. Peak Shaving
Discharge during expensive peak periods to reduce the site's import from the grid. This cuts bills during the highest-priced hours (typically 4-7pm).
3. Wholesale Trading
Additional revenue from Axle's flexibility markets — trading energy on wholesale markets when prices are favourable, independent of site consumption.
The goal: Make V2G a cashflow-neutral (or positive) customer perk — where the energy savings and trading revenue offset any costs, creating value for fleet customers without them changing their existing energy supplier.
Our Approach
We're not starting from scratch. Simtricity's Flux controller already manages batteries at two live community energy sites, trading on wholesale markets through our Axle Energy integration.
Same Flux controller. Same Axle market integration. Different asset type.
Why Simtricity?
Proven Technology
Our Flux controller and Axle integration are already live at two community energy sites, trading real energy on wholesale markets every day.
Fast to Market
We're adapting existing infrastructure, not building from scratch. The pilot can be operational within weeks, not months.
Real Revenue Data
We can show you actual market revenues from our existing sites, not theoretical projections. You'll see what V2G can really deliver.
What You Get from the Pilot
📦Hard Deliverables
- • Pilot dashboard showing charger state, dispatch events, and revenue summary — source code provided to Tellus
- • Skyprospector login with financial models (12-month access included, with data export)
- • COP11 accredited meter at site
- • Operational data in standard formats
- • Tellus charger API integration code (licensed)
⚡Demonstrated Capabilities
- • Live V2G dispatch responding to market signals
- • Bidirectional charge/discharge (if API supports)
- • Revenue generation from flexibility markets
🎓Knowledge & Understanding
- • UK V2G market value proposition
- • Technical requirements for scaled deployment
- • Clear view of build vs buy options
Bidirectional Dispatch from Day One?
Yes — if Tellus provides a working charger API with V2G commands and a bidirectional-capable vehicle. Simtricity's side is ready; the integration complexity is on the charger/vehicle side.
What Success Looks Like
A 3-month pilot is rapid timescales — success means the solution is stood up and working, not exhaustively validated:
After the Pilot: Build or Buy?
Simtricity's Flux is AGPL licensed — Tellus can study the code during the pilot. Afterwards, you can: (a) extend with Simtricity's commercial service, or (b) take the learnings and build your own solution. The data, techniques, and processes from the pilot are transferable knowledge.
Project Goals
Operational Pilot
Tellus has fully operational V2G charger(s) at a pilot site, integrated with wholesale markets via Axle.
Shadow Billing
Tellus can provide a "shadow bill" to their fleet customer demonstrating the value of optimised energy, even before the customer changes supplier.
Proven Economics
Tellus fully understands the financial value of their bidirectional charger asset class, backed by real data from actual market trading.
Revenue Potential
Based on Simtricity's existing deployments:
~£40k
Axle flexibility revenues per MW/year
~£70k
Import optimisation per MW/year
~£110k
Total potential per MW/year
What This Means for Fleets
| Configuration | Total Capacity | Annual Value |
|---|---|---|
| 60kW DC Bidirectional Chargers (e.g. pilot equipment) | ||
| 1 charger (60kW) | 0.06 MW | ~£6,600 |
| 10 chargers | 0.6 MW | ~£66,000 |
| 40 chargers (national rollout) | 2.4 MW | ~£264,000 |
Estimates based on ~£110k/MW/year total potential for bidirectional chargers. Actual revenues depend on vehicle availability, market conditions, and charger utilisation. Unidirectional chargers have value for smart charging (import optimisation) but significantly lower revenue potential, as discharge generates most of the revenue.
