Case Study: Large-Scale EV Charging Infrastructure for Government Department

Project Overview

A government department required a large-scale electric vehicle (EV) charging infrastructure to support the transition to a fully electric fleet. The goal was to ensure seamless operations, optimise energy efficiency, and future-proof the site for continued fleet expansion.

Quick Facts

• Client: Government agency

• Location: Auckland, New Zealand

• Scope: EV Charger Network for vehicle fleet

• Budget Outcome: Delivered under budget through strategic procurement

• Implementation Timeframe: 18-24 months from design to commissioning

• Key Benefit: Enabled full fleet electrification with optimised charging schedules

Solution

• Infrastructure Planning: Conducted a site assessment to optimise charger placement and power distribution.

• Scalability & Load Management: Implemented dynamic load balancing to prevent grid strain while enabling future expansion.

• Renewable Energy Integration: Designed for future solar and battery integration to lower operational costs.

• Cultural & Environmental Considerations: Collaborated with local iwi to respectfully relocate trees in line with Māori customs.

• Fleet Optimization: Configured a management platform for real-time usage insights and cost tracking.

Results

• Charger Deployment: 50 chargers deployed, supporting <80% of the total vehicle fleet on-site.

• Efficiency Optimisation: Advanced load management software reduced energy costs and balanced demand.

• Sustainability Contribution: Helped the department meet sustainability goals through carbon abatement.

• Scalability: Future-proofed infrastructure for potential fleet expansion.

• Operational Impact: Enabled quicker, more accessible charging for fleet vehicles.
