Entogo says DC fast-charging costs are driven by grid upgrades, not chargers

By AI, Created 4:47 AM UTC, June 01, 2026, /AGP/ – A new Entogo analysis says the biggest expense in DC fast-charging projects is usually electrical infrastructure, demand charges and storage, not the charger hardware itself. The finding points operators toward site planning, tariff reform and batteries as the main levers to control costs.

Why it matters: - DC fast-charging budgets can swing from about $50,000 to more than $1 million per site, making cost planning difficult for operators and investors. - Entogo’s analysis says the charger hardware is usually not the biggest cost, which changes where public charging projects should focus their spending. - The findings matter for NEVI-backed builds, fleet depots and other high-power charging sites that must meet tight timelines and utility requirements.

What happened: - Entogo published a new analysis of DC fast-charging station costs. - The analysis uses data from Atlas Public Policy and Paren, National Renewable Energy Laboratory deployment data and Rocky Mountain Institute rate-design work. - The study of 330 winning NEVI site awards found an average project cost of $915,420 and a median of $802,267.

The details: - Electrical infrastructure, including make-ready conduit and conductor, panels and switchgear, the transformer and any utility service upgrade, accounts for 30% to 60% of total project cost, based on NREL deployment data. - That electrical work often costs more than the charger hardware itself. - A 150 kW charger draws roughly 175 kVA of load, while a 350 kW charger draws more than 400 kVA. - Typical commercial sites are not pre-fed for that level of demand. - Above about 150 kW per port, utility-side costs rise faster than hardware costs. - Rocky Mountain Institute has documented cases where demand charges make up more than 90% of a public charger’s electricity bill at low utilization. - Demand charges are based on the single highest power draw in a period, not total energy used. - A brief 350 kW charging session can set the peak for an entire month. - The two main ways to reduce that peak are tariff reform, such as windowed or block demand charges, and an on-site battery system that clips the load. - Building a site EV-ready during initial construction cuts make-ready costs 40% to 60% per connector versus a later retrofit, according to NREL. - Fleet depots often cross $1 million in cost as the utility service becomes a custom substation. - Those depots increasingly add battery storage from the start, with designs governed by UL 9540, UL 1973 and NFPA 855.

Between the lines: - The analysis reframes DC fast-charging from a hardware purchase problem to a grid-integration problem. - That shift favors operators who plan for electrical capacity, demand management and storage early in the project. - The sourcing message is also strategic: bundling chargers, transformers, switchgear and batteries from one manufacturer can reduce engineering complexity and lead-time risk. - Entogo manufactures AC and DC chargers from 60 kW to 600 kW, pad-mount and prefabricated substation transformers, medium- and low-voltage switchgear, and battery energy storage. - Entogo says it ships European-standard catalogue equipment in an average of 12 weeks, and within 36 weeks when a product needs new UL or other North American certification.

What’s next: - Operators planning public charging sites are likely to keep weighing make-ready, utility upgrades, tariff design and battery storage before ordering charger hardware. - Entogo says its full EV charging infrastructure equipment line is documented on the company’s site. - Entogo publishes additional analyses at entogo.ca/insights.

The bottom line: - For DC fast charging, the charger is often the visible cost, but the grid work and demand charges are what really move the budget.
