MADISON — With 20 charging stalls under construction on Interstate 95, Madison is slated to join 31 other Connecticut municipalities that, according to a Tesla map available online, house Tesla charging stations.

And the stations coming to Madison may be more efficient than many currently found on the road: “Superchargers,” which charge vehicles in about 30 minutes and currently exist in just 10 Connecticut municipalities, according to Tesla’s website.

Most of the charging stations throughout the state are “Destination Chargers,” which take several hours of charging time, the website says.

Though Tesla’s Destination Chargers are available in towns including Branford, Guilford and Westbrook, I-95’s in-state Superchargers do not currently exist east of Milford, Tesla’s map indicates — though it also shows the company plans to open new Superchargers in Old Lyme and New London.

The map does not list Madison’s up-and-coming stations, but supercharge.info, a website that tracks station construction and was created by Tesla enthusiasts, indicates the Madison stations will have “supercharging” ability.

Elektrek, a media outlet that covers news relating to electric vehicles, also ran a story mentioning the new Madison stations.

Tesla could not be reached Tuesday to confirm the information.

Ten charging stalls appear to be under construction on either side of I-95, according to Ryan Duques, chairman of Madison’s Economic Development Commission.

The stations’ construction appeared to be almost finished, Duques said.

From the standpoint of economic development, Duques said he is excited about the charging stations.

Based on a conversation he had with the assessor’s office in Milford, where there are Tesla charging stations, Duques believes the stations will be added to the grand list.

“It will mean thousands of dollars to the town each year,” he said, adding that Milford gets just under $2,000 annually for the charging stations it houses. Though he was unsure of just how much tax money Madison would receive, he guessed that, based on the size of the installation, it would take in more than Milford does.

Duques speculated that the investment may have to do with Madison’s location between New York City and Boston.

“Anytime anybody makes an investment in Madison ... when I see that, I get excited.” Duques said. For him, it means “somebody else realizes how special Madison is.”

State Rep. Noreen Kokoruda, R-Madison, said she had not been notified of the installation but thought it was a great idea.

Connecticut Patch first reported the story.

The Connecticut Department of Transportation could not be reached for comment.
