Two US states, Washington and Texas, have announced plans to require electric vehicle (EV) charging stations to include Tesla's North American Charging Standard (NACS) plug. The move is a major victory for Tesla, which has been pushing for its proprietary plug to become the standard for EV charging in the United States.

The Washington state Department of Transportation (DOT) said that it would require all new EV charging stations funded by the state to include the NACS plug. The DOT said that the decision was made to "future-proof" the state's investment in EV charging infrastructure.

Texas also announced plans to require the NACS plug at EV charging stations funded by the state. The Texas Department of Transportation (TxDOT) said that the decision was made to "ensure that all EV drivers have access to charging stations."

The NACS plug is a newer standard than the Combined Charging System (CCS) plug, which is currently the most common standard for EV charging in the United States. However, the NACS plug is seen as having several advantages over the CCS plug, including its faster charging speed and its ability to support bi-directional charging.

Tesla has been pushing for the NACS plug to become the standard for EV charging in the United States for several years. The company has argued that the NACS plug is superior to the CCS plug and that it would be in the best interests of EV drivers to have a single, universal standard for EV charging.

The decisions by Washington and Texas to require the NACS plug at EV charging stations is a major victory for Tesla. The move is likely to put pressure on other states and the federal government to adopt the NACS plug as the standard for EV charging in the United States.

Here are some other details about the NACS plug:

• The NACS plug was developed by Tesla and other companies in the EV industry.
• The NACS plug is capable of delivering up to 250 kW of charging power, which is significantly faster than the CCS plug.
• The NACS plug can also support bi-directional charging, which means that it can be used to both charge EVs and to power homes and businesses.
• The NACS plug is not yet as widely available as the CCS plug, but it is gaining in popularity.

The decision by Washington and Texas to require the NACS plug at EV charging stations is a significant development in the EV industry. The move is likely to accelerate the adoption of the NACS plug as the standard for EV charging in the United States.
