VMD Companies, owner of an industrial building at 50 John Hancock Road in the Myles Standish Industrial Park, is asking Mayor Shaunna O’Connell to exempt some existing industrial properties from the proposed moratorium. In a letter to the mayor, the company said the delay could derail a pending agreement with a technology tenant whose identity it has not disclosed.

VMD’s filings with the Taunton Municipal Lighting Plant say the proposed project would use 24 megawatts of electricity in two phases: 13 megawatts initially, followed by another 11 megawatts. The company says qualifying existing industrial buildings should be exempt if they have already been approved, meet building codes and contribute property-tax revenue.

City leaders are proposing the pause to give Taunton time to review its rules and examine data centers’ potential demands on local infrastructure and power systems, as well as possible environmental effects. Area residents have also raised concerns about impacts to water resources and nearby communities.

“We need to really look at the impact,” said Peggy Hall of Easton, warning that large companies could impose costs on smaller communities. Jackson Isenstadt of Norton said a yearlong pause could give officials time to learn from legal disputes and other developments involving data centers elsewhere.

The council is scheduled to meet in the Chester R. Martin Municipal Council Chambers at City Hall. The proposal is under consideration; no moratorium has been approved.
