Delivering Municipal Net Metering Credit Value Across Massachusetts

Towns and cities across Massachusetts rely on net metering credits to reduce operating costs and support long‑term clean‑energy goals. But ensuring those credits deliver their full value requires vigilance, expertise, and a deep understanding of utility processes. That’s where Suntility Electric LLC steps in.

Suntility helps municipalities unlock the full potential of their net metering credit agreements. With decades of experience, strong working relationships with National Grid, Eversource, and state regulators, and a proven track record managing hundreds of solar projects and thousands of electric accounts, we make sure every credit is captured, validated, and optimized for maximum savings.

Precision Tracking, Validation, and Reconciliation

Net metering credits only generate value when they’re accurately applied. Suntility monitors each billing cycle, tracking every kilowatt hour and reconciling every credit. If something looks off, we flag it and work diligently to fix it. This includes:

Missing credits
Delayed postings
Miscalculations
Incorrect allocations

When discrepancies arise, we work directly with the utility to fully resolve them — leveraging our regulatory expertise to ensure your municipality receives the highest allowable value. No more lost credits. No more billing confusion. Just clean, optimized savings.

Clear Reporting and Predictable Costs

Municipal teams deserve clarity, not complexity. Suntility provides easy‑to‑understand quarterly reporting that highlights performance, savings, and any issues resolved along the way. And because our service is offered at one low, annual, fixed rate, budgeting is simple and transparent.

More Than Net Metering: Your Municipal Owner’s Agent

Beyond credit management, Suntility supports municipalities across the full solar operations landscape.

Schedule Z allocation adjustments
REC brokerage
System monitoring
Vendor coordination
Contract performance oversight

We act as your Owner’s Agent — protecting your interests, ensuring accountability, and helping your clean‑energy assets perform as intended.

A Smarter Way for Municipalities to Manage Solar

Suntility Electric LLC delivers the structure, oversight, and technical rigor that public‑sector teams need to confidently manage their solar portfolios. With us, your community gets the full value of its clean‑energy investments — without the administrative burden.

Massachusetts Focuses on Expanding the Community Benefits of Solar

As the state is just days away from approaching 16,000 cumulative solar installations, following the announcement of a state total of over 15,000 solar projects from earlier this week, the next round of photovoltaic projects in the Commonwealth will be uniquely local and equally as innovative. As highlighted by Governor Deval Patrick in a recent keynote speech on solar,

“We have a solar revolution underway here in the Commonwealth…Solar is a key part of our clean energy future. That future won’t happen overnight because it can’t, but it will happen because it wants to. And it will be up to all of us to make it happen.”

In a bid to expand the scope of solar, increase consumer options, and clean energy access, the following segments of solar installation will play a more central role in the progress to Massachusetts’ goals of 1600MW of solar by 2020:

– Small residential and commercial;

– Solar canopy units;

– Emergency power generation units;

– Community shared solar generation units; and

– Low or moderate income housing generation units.

Encouraged by proven models such as the 346kW Brewster Community Solar Garden™, and recognizing the possibilities to increase participation in the benefits of solar, these market segments will be key drivers of solar adoption in the years to come.

Community shared solar generation for example provides true consumer choice, allowing homeowners, businesses, and non-profits the ability to derive their energy locally, and with 100% renewable electricity. The Brewster Community Solar Garden™ facility, featured in a 2014 Enphase Energy press release represents a shining example of how a diverse and vibrant group of stakeholders in a community can work together and prosper from locally sited solar. Installed by My Generation Energy which has installed solar from Martha’s Vineyard to Marion, and from Quincy to Wellfleet, the project is managed by the comprehensive suite of Suntility Electric‘s solar management solutions.

“The Brewster Community Solar Garden™ project, as the first Community Shared Solar Project in the state, with nearly 3 years of operational experience, truly demonstrates the positive reception, broad benefits and strength of this exciting model,” Suntility Manager Michael Stone. “This collaborative approach to solar has successfully driven the reach of this clean, quiet, local power from beyond individual rooftops to numerous electric accounts in the area.”

Need help managing your Massachusetts Net Metering Credits? You’re not alone.

Unclear on the Schedule Z, or even what it is? Managing a lot of electric accounts? and a high volume of net metering credits? Have you experienced challenges with the utilities in the past? Are net metering credits something that you don’t have expertise in or don’t have the bandwidth to do, or both?

Commercial and utility-scale wind and solar project owners in Massachusetts have received a diverse set of incentives over the years. These include: rebates; grants; tax credits; accelerated depreciation; renewable energy certificates; and net metering credits. Managing the last set of incentives – net metering credits – is very often the most cumbersome with the unique combination of arcane utility regulations and the constant administrative attention required.

Ensuring everything is done properly by your Massachusetts utility, WMECO, National Grid or NSTAR, is absolutely critical considering the significant value of these credits. Whether you are the solar or wind owner allocating the credits or the recipient of the credits, such as a municipality, it’s important to know that you’re getting your full value and you’re optimizing the value of this important incentive. Absent dedicated professional management of your net metering credits and net metering credit accounts, you could very easily be losing tens of thousands of dollars through your own mistakes or those of the utility. At Suntility we’ve discovered and corrected hundreds of thousands of dollars worth of utility and user net metering credit errors.

Why Is My NSTAR Or National Grid Electric Bill So High?

Considering the rising cost, or value, of electricity it is definitely worth making sure that you are being billed for the appropriate amount and at the appropriate rate. At the same time utility billing and net metering credit regulations are becoming increasingly arcane for the average electric account holder with solar or wind. Therefore a regular detailed review of all of the constituent elements of your bill is important. Even as electric rates have gone up by significant amounts this winter due to cold weather and energy supply constraints, there are a number of key places on your bill where you can have control with the right expertise. If you’re a net metering facility ensuring that you’re receiving the proper net metering credits is key. The same is true if you are allocating or receiving credits through the use of a Schedule Z form. Properly managing your account will make sure you’re on top of, and reducing, one of the largest expenses for commercial and industrial organizations in Massachusetts – electricity.

Site Audits & Bill Audits are a Great Way to Start the Spring & Summer Solar & Wind Production Seasons

With the best months ahead for renewable energy production, and most specifically for solar, now is a great time to ensure your utility electricity account (NSTAR or National Grid) is in order and that your physical renewable energy facility is in good shape. Before spring is prime time to recognize any potential maintenance issues and also ensure your utility account will be providing you the best value through the peak production months ahead.

Many solar and wind projects are completed in early spring after the snow and ice has cleared. Therefore full technical audits at this time can offer a detailed picture of the workmanship of an installation and offer the peace of mind that you’ll be in the best position moving forward with your net metering credits and renewable energy certificates as well. Additionally for existing systems harsh winter weather conditions can also warrant further technical reviews. For solar and wind facilities worth millions of dollars, site audits and bill audits are both extremely cost-effective ways to help manage the significant investment you’ve made in clean energy.
