    2018 grid modernization order

    In May 2018, the DPU approved a Grid Modernization Plan for each Massachusetts electric company in Grid Modernization Order.  Each approved Grid Modernization Plan includes a 3-year short‑term investment plan and a 5‑year strategic plan.

    The pre-authorized investment categories include:

    • monitoring/control
    • distribution automation
    • volt/VAR optimization
    • advanced distribution management system
    • advanced communications infrastructure

    Grid modernization annual reports

    The 3 electric companies in Massachusetts must file a grid modernization annual report and performance data each year.  The reports also include performance metrics that measure the benefits of grid-facing grid modernization investments.

    Following the completion of the Grid Modernization Plan investment term, each electric company will file a Grid Modernization Term Report. 



    Grid modernization evaluation plan and evaluation reports

    The DPU required the electric companies to retain an independent consultant to develop an evaluation planThe evaluation plan studies the deployment of pre-authorized grid modernization investments.  The independent consultant will produce an annual evaluation report each year.
