Quantitative Underwriting Framework for EV Charging Infrastructure

The Physics of Coincident Peak Demand & Grid Interconnection

A high-power fleet depot connecting thirty-two 350 kW DC fast chargers possesses 11.2 MW of connected nameplate capacity—equivalent to the electric draw of a small town. Without managed power controls, simultaneous plug-ins create devastating coincident peak spikes.

Utility grid interconnection studies often demand expensive 3-to-5-year substation rebuilds or dedicated medium-voltage feeder extensions costing millions. Integrating behind-the-meter (BTM) Battery Energy Storage Systems (BESS) caps the peak import from the grid, avoiding queue delays and unlocking faster commercial operations.

Structuring Bankable Charging-as-a-Service (CaaS) Contracts

Pure merchant public charging exposes infrastructure owners to severe volumetric risk during early electric vehicle adoption curves. Commercial fleets requiring dedicated overnight charging solve this barrier through Charging-as-a-Service (CaaS) agreements.

Similar to Energy Service Agreements (ESAs) and solar Power Purchase Agreements (PPAs), CaaS structures bifurcate revenues into a fixed take-or-pay monthly availability fee ($/stall-month) covering debt service and capital return, while actual electricity costs (energy + demand charges) are passed through to the fleet operator on a transparent index formula.

Frequently Asked Questions

The demand charge trap occurs when high-power DC fast chargers create massive 15-minute coincident peak spikes billed under commercial utility $/kW-month demand charges ($15-$35/kW-month). During low depot utilization, this fixed monthly capacity fee is divided across very few delivered kilowatt-hours, driving the effective electricity cost to $0.60-$0.90/kWh and exceeding the retail dispensing revenue.

A BTM Battery Energy Storage System (BESS) discharges during peak simultaneous vehicle charging events to cap the facility's grid draw at a predetermined threshold (e.g., shaving 4,000 kW down to 2,500 kW). This reduces monthly peak demand charges by tens or hundreds of thousands of dollars annually, allows time-of-use energy arbitrage, and defers expensive utility substation upgrades.

Charging-as-a-Service (CaaS) provides turnkey EV charging infrastructure under a long-term (10-15 year) take-or-pay contract with fleet operators. Fleet tenants pay a fixed monthly availability retainer ($/stall-month) plus electricity pass-through costs. Senior infrastructure lenders prefer CaaS because contractual availability fees eliminate merchant volumetric risk, creating predictable Cash Flow Available for Debt Service (CFADS) for debt sculpting.

California CARB's Low Carbon Fuel Standard (LCFS) Fast Charging Infrastructure (FCI) provision allows qualified high-power DCFC stations to generate tradeable carbon credits based on the unutilized capacity of eligible chargers for up to 5 years. This provides an essential revenue bridge that covers debt service and fixed OpEx while fleet operators gradually ramp up vehicle deliveries.

The Levelized Cost of Charging (LCOC) is calculated as the present value of all capital expenditures (hardware, civil work, electrical switchgear, utility make-ready, and BTM BESS) plus discounted lifetime operating costs (utility energy and demand charges, software SaaS, maintenance, site lease, and insurance), divided by the present value of all kilowatt-hours dispensed over the asset lifecycle.
