Welcome to the Massachusetts Department of Public Utilities’ Grid Modernization Homepage
 

In June, 2014, the Department of Public Utilities issued an order (D.P.U. 12-76-B pdf format of D.P.U. 12-76-B Order
) requiring each electric distribution company develop and implement a ten-year grid modernization plan.  The Department determined that grid modernization will provide several benefits including:

•  empowering customers to better manage and reduce electricity costs;
•  enhancing the reliability and resiliency of electricity service in the face of increasingly extreme weather;
•  encouraging innovation and investment in new technology and infrastructure;
•  Addressing climate change and meeting clean energy requirements.

Procedural History

The Department’s investigation of grid modernization plans began in October 2012, when it issued a Notice of Investigation into the modernization of the electric grid (D.P.U. 12-76 ).  

From November 2012 through June 2013, stakeholders discussed grid-facing and customer-facing issues relating to the modernization of the grid.  On July 2, 2013, the stakeholders submitted a final report pdf format of 12-76 Report from Stakeholders on Grid Modernization.
file size 1MB  to the Department with their recommendations.  
To learn more about the grid modernization stakeholder process that was conducted from November 2012 through June 2013, please visit the facilitator’s website.

On December 23, 2013 the Department issued an Order (D.P.U. 12-76-A pdf format of 12-76-A Grid Modernization Straw Proposal
  ) containing a straw proposal for modernizing the electric grid.

On June 12, 2014, the Department issued an Order (D.P.U. 12-76-B pdf format of D.P.U. 12-76-B Order
) requiring each electric distribution company to submit a ten‑year Grid Modernization Plan outlining how the company proposes to make measureable progress towards four objectives:  (1) reducing the effects of outages; (2) optimizing demand, which includes reducing system and customer costs; (3) integrating distributed resources; and (4) improving workforce and asset management. 

On that same date, the Department issued a companion Order (D.P.U. 14-04-B pdf format of D.P.U. 14-04-B Order
) setting forth its anticipated policy framework for the implementation of time varying rates for basic service customers to provide direction to electric distribution companies as they prepare their grid modernization plans.

On November 5, 2014, the Department issued an Order (D.P.U. 12-76-C) outlining the requirements of the business case analysis to be used by each company to evaluate the costs and benefits of its Grid Modernization Plan.
