Power requirements depend on fleet size, charger type, and charging schedule. A depot with 50 electric buses using 150 kW chargers can require 5 to 8 MW of connected load. Depots with DC fast chargers for Class 8 trucks can exceed 15 MW. Prismecs conducts site-specific load assessments to confirm the actual capacity requirement before selecting the generation and storage configuration.
EV Charging Infrastructure and Power Solutions for Fleets
Prismecs provides power for fleet charging depots through on-site power generation, microgrid systems, and BESS integration, delivering the electrical capacity needed for high-demand charging infrastructure.
Powering Fleets Beyond
Grid Constraints
EV charging deployments can face insufficient grid capacity, lengthy utility interconnection approvals, and costly transformer and substation upgrades. Fleet depots and high-power charging hubs face additional pressure when multiple vehicles need charging within fixed turnaround windows, creating concentrated demand that existing electrical infrastructure may not support.
Prismecs helps overcome these constraints through integrated EV charging infrastructure and power solutions tailored to site capacity, charging requirements, and fleet operating schedules.

Frequently Asked Questions
When the local grid lacks the capacity to support depot charging loads, Prismecs configures on-site power generation for EV charging depots using natural gas generation, BESS, or microgrid systems. These solutions can be deployed in months rather than years, providing immediate charging capacity while permanent utility infrastructure is built.
Utility interconnection upgrades for multi-megawatt depot loads typically require two to five years, depending on substation capacity, transformer availability, and permitting timelines. Prismecs provides bridge power through leased or owned onsite generation that supplies fleet depot charging power while those utility improvements are completed.
Yes. Battery-buffered EV fast-charging systems absorb energy during off-peak periods and discharge during high-demand windows, reducing peak demand charges that can account for 50% or more of commercial electricity costs. Prismecs sizes BESS around actual depot load profiles and utility tariff structures to maximize demand-charge reduction.
Prismecs provides power infrastructure for electric bus and truck depots across transit, logistics, and last-mile delivery operations. Each depot configuration accounts for the specific vehicle types, charger ratings, duty cycles, and operational schedules that determine actual electrical load. Generation, storage, and distribution systems are sized accordingly.
Prismecs supports direct equipment purchase, short and long-term lease, equipment leasing, lease-to-own arrangements, and fully managed power packages. This allows fleet operators to match their capital and operating budget to their vehicle rollout timeline without committing full capital expenditure upfront.
