Constellation has been a pleasure to work with. Their representative assigned to Attleboro is knowledgeable and friendly. Questions are always answered in a timely manner. When I was looking at different vendors, I considered what we were getting and what others were offering and for how much, and I decided to keep the City with Constellation.

Products

Products and solutions to meet your energy needs.

Understand your facility usage and utility bills.

Analytics platforms such as Utility Bill Management can help you manage carbon emissions data associated with your utilities, including energy, water, sewer, and diesel. Use it to generate valuable insights, such as baseline energy usage data and how energy efficiency upgrades and other options can reduce emissions.

Make energy efficiency upgrades

Energy efficiency upgrades, such as LED lighting and HVAC upgrades, can help reduce energy consumption and carbon emissions. With Constellation’s Efficiency Made Easy® (EME) program, you can implement those infrastructure improvements with no upfront capital.

Purchase EFECS and RECS

Emission-Free Energy Certificates (EFECs) represent the emission-free attributes of generating sources that do not emit greenhouse gases, such as solar, wind, nuclear and hydropower. At today’s prices, these are the most cost-effective certificates available. Renewable Energy Certificates (RECs) represent the emission-free attributes of one megawatt hour (MWh) of electricity generated only by renewable power plants, such as from wind or solar power.

Explore renewable natural gas

Directly reduce greenhouse gas emissions resulting from natural gas consumption by matching your gas purchases with environmental attributes of renewable natural gas (RNG), derived from sources including landfills, wastewater treatment plants and commercial & agricultural waste digesters.

Leverage carbon offsets

Indirectly reduce such emissions through the purchase of carbon offsets, which represent a verified reduction in emissions of carbon dioxide or other greenhouse gas emissions made elsewhere through forestry, energy efficiency, industrial process improvements and carbon capture & sequestration projects.

Procure offsite renewables

Through Constellation Offsite Renewables solutions, you have the ability to go beyond purchasing certificates and integrate energy from specific renewable energy projects in your region. Purchase renewable energy from existing (CORe) or new-build (CORe+) generation, including solar and wind facilities, into load-following energy supply.

Pursue Hourly Carbon-Free Energy Matching of clean electricity with your load

By matching your electricity use with a local emission-free energy source in real time, you can go beyond other net-zero programs to allow you to eliminate the carbon impact of your operations and fully achieve zero emissions goals.

The Senate today passed a transportation bond bill that includes $300 million for the Chapter 90 program in fiscal 2027 to support local transportation infrastructure projects across the Commonwealth. The $300 million allocation matches last year’s funding level, which represented a 50% increase over previous years — and would benefit all 351 Massachusetts municipalities as they head into peak construction season. Of the total, $200 million would be allocated under the traditional formula, and $100 million would be distributed based on road mileage in a bid to boost regional equity. The $1.4 billion transportation bond bill H.5375 also includes the following infrastructure investments: • $500 million for the Massachusetts Department of Transportation’s Bridge and Pavement Lifecycle Asset Management Programs •...

The Senate this evening passed a fiscal 2027 state spending plan that includes a $53 million increase for Unrestricted General Government Aid and minimum new education aid of $160 per pupil. After four days of deliberation and the consideration of more than 1,100 amendments, the Senate passed a budget bill totaling $63.4 billion. The Senate bill includes language to create commissions to study distribution formulas for the two main local aid accounts: Chapter 70 education aid and UGGA. MMA Executive Director Adam Chapdelaine said the Senate’s bill reflects “an important focus on the partnership between state and local government through a critical program — Unrestricted General Government Aid — with investments that help to reinforce that partnership, at a time...

Legislation aimed at keeping federal immigration enforcement out of sensitive places has passed the House and Senate and now moves to a six-member conference committee to resolve differences between the two versions. The legislation — “promoting the rule of law, oversight, trust, and equal constitutional treatment” or PROTECT — was filed by Gov. Maura Healey in January, along with an Executive Order prohibiting federal Immigration and Customs Enforcement personnel from making civil arrests in non-public areas of state facilities, and prohibiting the use of state property for immigration enforcement staging. The House and Senate versions of the bill differ in their scope. The House version, passed in March, would restrict warrantless arrests in courthouses and includes language that would allow...

Major sections of the governor’s proposed Municipal Empowerment Act have been sent to the House Committee on Ways and Means and are awaiting action in the last months of the current legislative session. The wide-ranging bill, strongly supported by the MMA and local leaders, is intended to increase municipal flexibility, reduce administrative burdens, strengthen municipal finances, address municipal workforce challenges, and improve the efficiency of local operations. After Gov. Maura Healey filed the bill last year, various portions were initially assigned to three committees: the Joint Committee on Public Service, the Joint Committee on Municipalities and Regional Government, and the Joint Committee on Revenue. The House Committee on Ways and Means now holds the bulk of the bill’s provisions after...

In partnership with Learning Lab International, the MMA is offering a “cross-sectional” professional learning opportunity for municipal teams called Leading Now. Cross-sectional teams intentionally bring together an array of key roles (elected and appointed) from all corners of the government to undergo intensive leadership development as a group, with a particular focus on leading through change and leading for equity. Leading Now, based on the Massachusetts Department of Elementary and Secondary Education’s successful Leading With Perseverance coaching series, is the MMA’s first cross-sectional professional learning opportunity. The MMA is now recruiting municipal teams to participate. The goal is to have teams of five to 10 members (ideally eight to 10) from between 10 and 12 cities or towns. All of...

Gov. Maura Healey filed a legislative package on May 4 that would create a comprehensive regulatory framework for motorized “micromobility” vehicles in an effort to bolster public safety. The governor’s Ride Safe Bill reflects recommendations made by a Special Commission on Micromobility, on which the MMA had two seats. The use of micromobility devices, such as motorized bikes, scooters and skateboards, has been on the rise, but local and statewide regulations have not been able to keep up with the quickly evolving landscape of the technology. Central to the legislation is a new, speed-based framework for categorizing various micromobility devices. Lower-speed e-bikes, not exceeding 20 miles per hour, would continue to follow standard bike lane rules, with an added helmet...

Following below-normal precipitation levels in April, Energy and Environmental Affairs Secretary Rebecca Tepper on May 8 announced that drought levels had been increased in several regions of the state. The Central, Connecticut River Valley, Nantucket County, and Northeast regions are now at a Level 2: Significant Drought. The Southeast and Western regions, along with Dukes County (Martha’s Vineyard), are now at Level 1: Mild Drought. The Cape Cod region improved since last month to Level 1. While recent rainfall has helped conditions, Tepper said the state is still experiencing low river and groundwater levels. “As we move through the growing season, many communities have water restrictions in place,” Tepper said. “Using water wisely, both outdoors and indoors, can help reduce...
