Depot Charging Strategy: Grid Upgrade vs Battery-as-a-Service
Reducing cost, eliminating grid constraints, and enabling scalable fleet electrification.
The Bottleneck Blocking Fleet Electrification
As commercial fleets transition to electric trucks and buses, depot charging demands are escalating rapidly. Yet the infrastructure required to support this transition is becoming a critical barrier — not a solved problem.
Grid Upgrades Are Slow
Utility-led grid reinforcement projects routinely take 1–2 years, leaving fleets grounded during the transition window.
Capital-Intensive & Uncertain
Upfront connection upgrade costs can exceed £500,000 — with no guarantee of approval, timeline, or cost certainty.
Capacity Constrains Scaling
Fixed grid connections cannot flex to meet growing fleet demand, forcing operators to delay or limit EV adoption.
Peak Demand Charges Escalate
Simultaneous vehicle charging during peak periods triggers punishing demand tariffs, inflating daily operating costs.
Key Message: Grid capacity is becoming the single greatest bottleneck for fleet electrification — and traditional infrastructure responses are too slow, too costly, and too rigid.
Two Paths Forward
Fleet operators facing depot charging constraints have two very different options. One locks in cost, delay, and risk; the other enables faster, more flexible electrification.
Faraday GridShield
- On-site battery storage deployed in weeks, helping you electrify without waiting for grid upgrades
- A scalable charging solution that adapts as your fleet grows
- A pay-per-use model that avoids ownership burden and degradation risk
- A fully managed asset with Faraday Battery handling maintenance end to end
1MW Grid Connection Upgrade
- Significant upfront capital spend (£500k+) for connection charges, civils, and planning
- 1–2 year utility lead times, with approval and delivery timelines outside your control
- A fixed connection that offers little flexibility as fleet demand increases
- Ongoing peak demand charges and standing fees that continue to pressure operating costs
Energy Demand Baseline
To provide a like-for-like comparison, both options are modelled against the same reference fleet and daily energy demand. This baseline is conservative and intentionally designed to be scalable — the economics improve further as fleet size grows.

kWh/Day Required
Total daily energy demand across all vehicles at full operational utilisation.
Peak Grid Demand
Maximum simultaneous draw during peak charging periods — triggering demand tariff charges.
Operating Days/Year
Commercial depot operations modelled year-round for annualised cost comparison.
Scalability Note: This model represents a 3-truck entry-level fleet. The BaaS model scales linearly — larger fleets generate proportionally greater savings versus the grid upgrade alternative, with no additional infrastructure lead time.
Capture the Cheapest Renewable Energy
Faraday GridShield's integrated GreenCharge intelligence continuously monitors key variables to ensure your fleet is charged in the most cost-effective and sustainable way possible.
Wholesale Prices
Optimise charging based on real-time electricity market rates, always seeking the lowest cost.
Fleet Demands
Integrate charging schedules with fleet operational requirements to ensure vehicle readiness.
This dynamic approach ensures GridShield is charged when electricity is cheapest and greenest, translating into significant operational savings and environmental benefits.
Strategic Advantages of the Faraday BaaS Model
Faraday GridShield does more than cut costs — it gives fleet operators a faster, more resilient, and more controllable path to electrification than a grid upgrade ever can.
