National Grid Submits Comprehensive Performance Investment Plan as Part of Rate Review to Build a Smarter, Stronger, Cleaner, and More Equitable Energy Future


Highlights of National Grid’s Comprehensive Performance and Investment Plan and Rate Review Filing:

  • The state’s first-ever equity-based approach to discount rates for income-eligible customers.
  • An innovative electrification rate to support customers’ choices and enable the energy transition.
  • Targeted programs and dedicated teams to better serve customers and meet their needs.
  • Enhanced system resiliency and reliability measures to avoid and reduce the impact of outages.
  • Grid investments to support economic development, connect clean energy, enhance security.
  • A transparent system to review, track, and pay for major electric system investments.
  • A performance-based approach to drive the company to manage costs and improve efficiencies.
  • Measures holding the company accountable to deliver outcomes of investments and programs.
  • Incremental economic activity across Massachusetts totalling nearly $750 million, supporting more than 6,000 additional full and part time associated jobs.

WALTHAM, MA – Massachusetts Electric Company and Nantucket Electric Company, which are part of National Grid, filed with the Massachusetts Department of Public Utilities (DPU) a Comprehensive Performance and Investment (CPI) plan, as part of its required Rate Review filing, designed to deliver the fair, affordable and clean energy transition, reinforce the local energy grid, and hold the company accountable to achieving a smarter, stronger, cleaner and more equitable energy future for the 1.3 million customers the company serves across the Commonwealth.

“The proposal we’ve filed today, coupled with our electric sector modernization plan, Future Grid, will deliver the fair, affordable and clean energy transition for all our customers and communities,” said Nicola Medalova, the COO of Electricity for National Grid New England. “Fulfilling this mission requires a smarter, stronger, cleaner grid that can meet the rising power demand driven by electrification to support the Commonwealth’s climate and clean energy goals, while ensuring the system is there when customers need it – no matter the weather. Today’s proposal reflects the core investments necessary to strengthen the local electric grid, while holding ourselves accountable to meeting our customers’ expectations.”

Building the Foundation for the Future

The CPI plan details the core investments needed in the system over the next five years to build the foundation for the clean energy future, including hundreds of projects to modernize and reinforce the local energy grid and improve system performance through the replacement and upgrade of substations, poles and wires, the implementation of technology and programs designed to help avoid power outages that can be prevented and restore power faster to customers for outages that can’t be prevented, and the expansion of system capacity to meet growing customer and community needs and ensure the grid is ready when they need it.

The plan also includes innovative rates and programs to drive energy equity, support electrification, and improve the overall customer experience by providing more and easier to access information on clean energy solutions and services and bill management options.

Delivering a More Equitable, Resilient and Customer-Centric System

As proposed in the CPI plan, National Grid will deliver an energy future that is more equitable, more reliable and resilient, and improves the overall customer experience, by:   

  • Supporting Affordability and Equity.  Implementing a tiered discount rate program – a first for Massachusetts --  that provides larger discounts for some income-eligible customers, coupled with a robust and sustained outreach and awareness campaign. Currently customers eligible for a reduced electric rate receive a 32% discount. The company is proposing a more equitable approach which would result in discounts of 32% up to 55%, depending on income and energy burden, for customers earning 60% of the state median income or less. The filing also proposes a dedicated team to engage eligible customers through in-person events and targeted outreach to increase program participation.
  • Enhancing Reliability and Resilience. Deploying technology – known as reclosers -- to automatically restore power to as many customers as possible as quickly as possible, in the event of a system fault, expanding an enhanced tree trimming program, and deploying “tree resistant” wires to minimize system impacts from fallen limbs. Over the past decade, National Grid experienced more severe storms across its system, more than doubling from an average of 4 per year to 10 per year. These and other investments will ensure customers continue to experience the high levels of system reliability they do today and reduce the costs of increased storm-related damage.
  • Empowering Customers and Improving Their Experience. Enhancing the customer experience by improving customer interfaces for transactions – including customer connections -- and expanding customer offerings and digital options. The company is also proposing an opt-in electrification rate to support customer energy choices and the transition to cleaner energy, while upgrading its customer systems and establishing dedicated teams to provide more tailored and relevant information and communications to help customers manage bills, reduce costs and access energy efficiency and clean energy solutions.

Driving Performance, Accountability and Transparency

To deliver on the CPI plan, the company has proposed a regulatory mechanism that will drive accountability, transparency, performance, and predictability for customers by requiring National Grid to proactively lay out its investment needs, plans and associated costs over the next five years, while placing the onus on the company to deliver customer, climate and reliability outcomes within an approved budget, or risk penalties. For example, the company has proposed metrics to hold it to account for, among other things, enrolling eligible customers in discount rate programs, on-time and on budget delivery of construction projects, adoption of clean energy requirements and reducing greenhouse gas emissions.

How Today’s Filing Supports National Grid’s Future Grid Plan 

The work included in today’s filing sets the foundation for the investments that are part of the company’s Future Grid plan, which was submitted as National Grid’s Electric Sector Modernization Plan to the Grid Modernization Advisory Council on September 1, 2023. The company’s Future Grid plan focuses on investments needed in addition to the core investments included in today’s filing to meet Massachusetts’ climate, clean energy and electrification goals. The electric system must be more resilient and reliable to meet the expected growing demand for electricity as more customers adopt electrified technologies like cars and heat pumps.

Impacts on Customer Bills

To ensure the company invests, operates, and maintains its distribution system wisely, the proposal will undergo a thorough review process by the DPU that typically lasts 10 months and provides for public input and comment. If approved, the proposals would take effect October 1, 2024, with new bills being issued starting November 1, 2024.  

If the plan is approved, a typical residential customer using 600 kWh per month would experience an annual average increase of 2.2% per year over the 5-year investment period, or $4.86 increase in a monthly bill, resulting in an increase of approximately $110 million in revenues per year over the same period.    

The increase would take effect October 1, 2024, for the first year of the rate term with a $7.86 (3.7%) impact in a monthly bill for an average customer, with further increases averaging 1.8% per year for the remaining four years of the rate plan term, translating into a 2.2% average annual impact over the five years (2024-2029).  

As part of today’s filing, the company also identified the costs associated with its Future Grid plan and requested that the DPU allow the company to use the proposed cost recovery mechanism in the CPI plan to recover associated investments. The company will make its formal Future Grid plan filing with the DPU in January 2024, which will also undergo a thorough review process that provides for public input and comment. If the Future Grid plan is approved, the average customer would see an additional impact of less than 1% on their monthly bill, for a total of approximately 3.0% increase on an average annual basis over the 2024-2029 period. If the Future Grid proposal was approved, it would result in an additional $44 million-a-year in revenues over the five-year rate term.

What Happens Next? 

The DPU will begin its review of the filing and will schedule public hearings across the state providing an opportunity for public comments from customers and interested members of the public. The dates, times, and locations of those hearings and comment period will be available on the DPU’s website and will also be included on our Massachusetts Grid Modernization website.
