Massachusetts Utility Partners with Tantalus for Grid Modernization

Published on April 2, 2025

The Reading Municipal Light Department (RMLD), a Massachusetts-based utility, has partnered with smart grid technology provider Tantalus Systems to modernize its distribution grid.

The collaboration will deploy Tantalus’ Grid Modernization Platform (TGMP) to transform RMLD’s infrastructure into a multi-directional grid. The platform integrates connected devices, communications networks, and data analytics to improve grid visibility and control while bridging IT and operational systems.

The upgrade aims to enhance data interoperability, operational efficiency, and sustainability. Tantalus’ TRUSync Grid Data Management System will automate grid data integration, helping RMLD optimize power quality, outage response, and resource allocation. The modernization will also support distributed energy resources (DERs) and electric vehicle integration.

RMLD serves over 70,000 residents across four Massachusetts communities and is the state’s largest municipal utility by electricity load.
