According to Reuters, Kentucky is the latest state to mandate that EV chargers include Tesla’s plug if the companies installing them want access to state funds.

Reuters reports that “in addition to federal requirements for the rival Combined Charging System (CCS), Kentucky mandates Tesla's plug, called the North American Charging Standard (NACS), at charging stations, according to Kentucky's request for proposal (RFP) for the state’s EV charging program.”

Last month, Ford announced that it would equip future models with the NACS charge port, in what was perceived as a major win for Tesla’s system.

“The CCS is a great standard, but it was pretty much done by kind of a committee, and I think GM and others are going to have a big choice to make,” Ford CEO Jim Farley told CNBC at the time. “Do they want to have fast-charging for customers? Or do they want to stick to their standard and have less charging?”

Ford’s announcement was followed several weeks later by Texas announcing that it would require EV charging companies to include both the CCS and NACS standards. EV maker Rivian also announced it would adopt Tesla’s charging standard.

The federal government continues to require CCS plugs. A group of EV charging firms pushed back against the Texas announcement, writing that “time is needed to properly standardize, test, and certify the safety and interoperability of Tesla connectors across the industry.”
