California Sets Aside $28M for Fast Chargers: Up to $100,000 per Port

California has opened a new $28M funding round for public DC fast chargers. The maximum payout is $100,000 per port and can cover up to 100% of eligible costs. Only ports rated above 275 kW get the highest rate. Yet charging equipment manufacturers' own data points the other way: the number of connectors raises a station's utilization more than peak power does.

The sum is small by market standards. If the entire budget went only to top-tier ports, the program would pay for no more than 280 ports: $28M divided by $100,000. In practice there will be fewer, because some applications will receive lower rates.

How the program works

The mechanics are simple: the money is tied to the port, not to the site. The rate rises with power, and the top tier starts at 275 kW. For an operator, that is a direct signal about which hardware to design the application around.

Key parameters of the round:

• total budget: $28M;
• maximum per public DC port: $100,000;
• coverage: up to 100% of eligible costs;
• condition for the top rate: port power above 275 kW;
• what is supported: public DC fast chargers.

A 100% coverage level is uncommon. Regulators usually require operators to put up matching funds so they share the risk. Here the ceiling lets a project spend not a cent of its own money, but only if the costs are deemed eligible. The round's rules define what counts as eligible, and the short announcement does not make that clear.

Where the logic falls short

The main objection to the design is that the money goes where power is higher, while demand is driven by something else. According to charger manufacturers cited by TNW, the number of connectors at a site increases utilization noticeably more than adding kW to each one. The explanation is straightforward. A driver who pulls up to a two-port station where one port is occupied and the other is broken will not appreciate 350 kW. They need a free connector.

High power has its own limits. Most electric vehicles cannot accept 275 kW or more across the whole charging range. The charging curve drops, and a car may receive noticeably less than its stated maximum. Some of the expensive equipment will run at half strength. And a grid connection at these power levels requires costly transformers and approvals from the utility. These expenses often exceed the cost of the charging cabinet itself.

This creates a skew. An operator with a limited budget may choose fewer but more powerful ports, because each one earns more. That is not the best outcome for the network as a whole: fewer connectors mean longer queues.

Practical takeaways

For operators, the application should be built from a utilization model, not from the subsidy's price list. If a site gets twice as many 150 kW ports, it will most likely serve more cars than a site with fewer ports above 275 kW. But the second option earns more money per port. Operators need to run both scenarios, factoring in grid connection costs and the real vehicle fleet profile in the area.

For equipment manufacturers, the round creates demand for cabinets above 275 kW, specifically in California. That favors those whose product lines are already certified.

For municipalities and site owners, the takeaway is to negotiate leases for a cluster of several ports rather than for a single high-power connector. If the round's rules do not change, the gap between the subsidy's logic and the logic of demand will remain. In that case, the winning applications will be those that combine both criteria well: many ports, and power above the threshold where cars can actually accept it.
