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.

Effective public sector supervisors play a central role in delivering high-quality municipal services. They must communicate clearly, motivate teams, resolve conflicts, and manage performance while upholding public-sector standards and expectations. To support supervisors in strengthening these essential skills, MIIA will offer a six-session “Management Skills for Public Sector Supervisors” training series for MIIA members this spring in partnership with the Public Sector Consortium. Designed for frontline supervisors with two to 30 years of experience, the series will cover one supervisory practice per session and emphasize skills that support effective daily operations. The training sessions are scheduled for March 12, 19 and 26, and April 9, 16 and 23 at the Southborough Public Safety Complex in Southborough. Participation is limited to...

In years past, winter was viewed as the primary season for property losses, especially here in New England, where freeze-ups, burst pipes and heating system failures remain among the most severe claims for municipal entities. Indeed, last year’s MIIA claims activity reaffirmed that winter hazards remain a significant concern. At the same time, recent MIIA claims data also confirms that losses tied to sudden heavy rainfall and localized convective storms are an increasing issue, bringing volatility throughout the calendar year. Municipalities are seeing property damage during months that were once considered relatively quiet, particularly late spring and summer, said Stephen Batchelder, vice president of Claims Operations and Risk Management at MIIA. “It’s important to recognize that risk now extends across...

The Worcester Affordable Housing Trust Fund awarded $1.25 million in October to eight housing projects that will create 59 affordable rental and homeownership units. The units represent a mix of housing types, from single-family to multi-unit. The city’s affordable housing trust fund was created about three years ago with about $18 million from the American Rescue Plan Act, all of which has been allocated. In November of 2022, city voters passed the Community Preservation Act, and the $1.25 million approved this fall is the first round using CPA funds. The city also completed its first-ever housing production plan this year. “We wanted to … do a deep dive on our demographics,” said Worcester Chief Development Officer Peter Dunn, “to make...

Following months of below-normal precipitation levels, Energy and Environmental Affairs Secretary Rebecca Tepper on Jan. 12 announced an increase in the drought level for the Central, Northeast and Southeast regions of the state, the Millers River Basin, and Nantucket County, meaning that much of the state now faces significant to critical drought. The changes follow a multi-month period during which much of the state has received below-average precipitation, which has impacted both streamflow and groundwater levels, Tepper said. Streams are drying up and groundwater conditions are worsening, especially on Cape Cod and Nantucket, where groundwater levels are below normal. Despite rainfall events in December, a lack of consistent precipitation has elevated fire risk throughout the state. Nantucket County and Millers...

State budget leaders announced an agreement on Jan. 14 on a state revenue forecast for fiscal 2027, predicting a 2.9% increase. Facing predictions of slow economic growth and general uncertainty due to federal policy actions, Administration and Finance Secretary Matthew Gorzkowicz, Senate Ways and Means Chair Michael Rodrigues and House Ways and Means Chair Aaron Michlewitz estimate that the Commonwealth will collect $44.9 billion total tax revenue in fiscal 2027. This figure includes $2.7 billion in revenue from the surtax on incomes over $1 million, a revenue stream that must be used for transportation and education programs. Excluding the surtax, leaders estimate $42.2 billion in tax revenue for the coming fiscal year, representing a 2.4% increase. State leaders agreed to...
