Priority Zones for Fast Charger Infrastructure
🔌 High-Density Urban Areas (St Helier)
Why critical: Most rental flats and older homes rely on on-street parking.
Current coverage: Public car parks like Pier Road (8 chargers), Patriotic Street, and Minden Place have some EV points.
Upgrade need: Reinforce underground cabling and add substations near residential blocks to support curbside fast chargers.
🏘️ Suburban Growth Zones (St Brelade, St Saviour, St Clement)
Challenge: Mixed housing with limited driveway access.
Current status: Sparse public chargers (e.g. Red Houses, Woodford).
Action: Install new feeder circuits and expand transformer capacity beneath key roads like La Route Orange and Rue du Crocquet.
Rural and Coastal Parishes (St Peter, Grouville, Trinity)
Issue: Long cable runs and low-voltage networks.
Example: Goose on the Green in St Peter has 11 chargers, but surrounding areas are underserved.
Solution: Use smart load balancing and solar-backed hubs to avoid costly trenching.
Electricity Network Upgrades Underway
Jersey Electricity’s £120 million “Big Upgrade” includes:
Doubling annual cable laying from 7km to ~15km
Upgrading 10% of the low-voltage network to handle EV and electric heating demand
Using smart meters and a “digital twin” of the island’s grid to pinpoint stress zones
This will support a projected 25% increase in peak electricity demand by 2030.
📈 Estimated Charging Point Growth
To meet demand by 2030:
Jersey may need ~2,000 public chargers, up from ~100 today
That’s ~250 new chargers per year, with a mix of 7kW, 22kW, and 150kW units
Fast chargers (50kW+) will require dedicated circuits and transformer upgrades, especially in St Helier and St Brelade
