How preventative maintenance keeps a Connecticut solar project running smoothly
For solar projects to successfully operate beyond their warrantied lifespans, they must be built correctly and need to be faithfully maintained. Solar contractors that handle both construction and operations and maintenance (O&M) stay with a solar project for the long term to ensure the array is meeting all its milestones.
Greenskies Clean Focus, a Connecticut-based commercial and utility-scale developer, recently completed a solar project seven years in the making. The company’s in-house O&M arm is maintaining an 18.86-MW array in Waterford, Connecticut, that has some unique upkeep requirements.

“If you don’t have an active preventative maintenance program going around and looking at everything, you are going to have equipment failures, and they are going to be much more serious than if you had caught them in the act,” said Steve Martineau, Greenskies’ director of O&M.
The project, built on approximately 94 acres of hilly land, was interconnected in April 2023. Greenskies is checking the array monthly to keep it operating at its peak.
“It allows us to be proactive instead of reactive,” said Chip Florio, director of project delivery at Greenskies, of the regular maintenance tasks. “If we’re reactive to these problems, it means that we’re scrambling to send people out, and everything becomes a fire drill. Being proactive vs. reactive allows us to better manage it.”
Preventing downtime at the Waterford solar project
A solar project of this scale is on the larger side for Connecticut and the greater New England region. The array is divided into five subsystems with different topographical and shading considerations. The first starts at the highest elevation on the site and the remaining four subsystems follow the topography downhill and then up a proceeding hill. The site was previously heavily logged and some trees unfit for logging had to be removed by Greenskies.
Sections of the land are laden with rock, so Greenskies opted to use a ground screw foundation from APA Solar Racking to work in the less-than-ideal soil conditions. The array also used APA racking and a mix of HT-SAAE and Canadian Solar panels with Yaskawa Solectria string inverters.
Greenskies O&M teams focus on project monitoring and protective and corrective maintenance of solar arrays. Martineau said each crew informs the next department along the maintenance line to keep arrays online and operating in peak condition. On the Waterford project, and every other array under Greenskies’ purview, O&M crews monitor inverter performance and open each unit for inspection at least once a year.
“Everything flows from financial institutions. So, there’s certain expectations that your financing partners have of us in an O&M facility,” he said. “It’s a collection of preventative maintenance and corrective maintenance.”
Heat detection is crucial on electronic components like inverters and switchgears because it can indicate future electrical issues on an array. O&M crews also monitor high-value components like transformers, because one malfunction will cause substantial production losses and take a lot of time to replace.
“In general, your biggest pain points come from those items that have the longest lead times when they fail, so you pay the closest attention to them,” Martineau said.
Prior to interconnection, water breached one of the array’s combiner boxes. Luckily, installers managed to swap the component in time for energization, the ongoing issue of water at the site pertains more to its environment.

Greenskies had 15 stormwater basins dug out near the project to prevent erosion and water runoff. There are two rivers running near the project, increasing the risk of stormwater runoff entering local waterways.
To ensure the basins are working properly, they were inspected once a week during construction, and they’re now inspected once a month. This monthly inspection routine will last for two growing seasons following the project’s completion in 2023.
“Between the weekly, monthly, and post-construction inspections, stormwater and erosion control measures are frequently overseen by multiple parties to ensure all necessary compliance,” said Florio. “It’s definitely a topic of importance.”
In addition to stormwater concerns, there are two basins on site that are fenced in to prevent local amphibians from laying eggs within. These basins dry out in the early summer, so biologists will visit the project every March to relocate any amphibious eggs to safer ponds. A safety plan was also in place to work around an endangered snake species native to the area.
“Those are outside our normal electrical O&M on the systems, but they’re equally important,” Martineau said.
As an end-to-end solar developer and EPC contractor, Greenskies owns the projects it builds for the long term. Dedicating a segment of the company to O&M of arrays like the one in Waterford ensures inevitable hardware failures are addressed before they happen or before they’re a larger detriment to the system.
“O&M with Greenskies is a front-of-the-mind thought and not an afterthought,” Martineau said. “O&M gets a lot of input into our installation practices, which is a great place to be when you’re a company like us, because we’re not big, but we get a lot done.”

At Yale, McMahon says she’ll shut down ‘bureaucracy of education’
U.S. Education Secretary Linda McMahon said Thursday she is working to “shut down the bureaucracy of education,” telling an audience in New Haven that she wants to diminish federal involvement in schools and give more discretion to states.
Speaking at an event on the campus of Yale University, McMahon defended moves by President Donald Trump’s administration to radically reshape the Department of Education since his return to office.
McMahon said the federal government will continue providing education funding in the future, but direct more of it through block grant programs that empower states to spend the money where it’s most needed.
The approach will help school leaders identify promising programs that can be replicated across the country, McMahon said.
“I want to leave behind, if you will, a toolkit of best practices that you can deliver to states to say, ‘Look, this is what’s working. You might want to give this a try,’” McMahon said.
Her remarks come amid controversial policy shifts in higher education by the Trump administration, including moves to freeze billions in research funding and grants to universities and pressure schools to address antisemitism, crack down on campus protest and eliminate diversity, equity and inclusion programs, among other changes.
McMahon, a Greenwich resident and former CEO of Stamford-based World Wrestling Entertainment, stood by the administration’s tactics, saying the threat of withholding funds is a tool it can use to ensure universities spend money wisely and for the intended purpose.
“The goal is really to make sure that universities are giving equal opportunity across their campuses,” she said.
McMahon’s visit was part of a speaker series organized by the Buckley Institute, which describes itself as an independent nonprofit working to promote intellectual diversity and freedom of speech at Yale.
McMahon served as administrator of the U.S. Small Business Administration during Trump’s first term. She later helped establish Trump’s second administration as co-chair of his transition team, and was confirmed as education secretary last year.
During an appearance that lasted about 45 minutes, McMahon did not address many of the divisive policy changes enacted under her leadership. She said promoting literacy is her top priority, and touted the importance of school choice programs and career and technical education.
McMahon said she visited a community college in Connecticut earlier in the day, and met with the president of Yale during her stop at the school’s campus, which included a visit to Science Hill, the site of a major redevelopment project to support cutting-edge research into physical sciences and engineering.
Responding to a question from the moderator, McMahon also said she discussed so-called grade inflation with Yale’s president.
“One of the things that the university is looking at is to make sure that professors are grading accordingly in their classes, and that there’s not this grade inflation,” she said.
McMahon also briefly addressed recent controversy around a planned visit to an elementary school in Fairfield. Just hours after the event was announced, Fairfield Public Schools told families it was canceled due to community backlash.
McMahon said the event was planned as part of her nationwide “History Rocks!” tour, which celebrates the country’s 250th anniversary. Events typically include trivia games focused on history and civics that don’t have a partisan slant, she said.
“These are really feel-good programs of assembly,” she said, “and when you get that pushback from parents who are saying no this is going to be partisan … it’s really a minority of a few loud voices that are just calling … to maybe just make a statement of their own.”
McMahon has run unsuccessfully as a Republican for U.S. Senate in Connecticut. In 2009, she served for one year on the Connecticut Board of Education, appointed by then-Gov. Jodi Rell, a Republican. She has also served on the board of trustees of Sacred Heart University in Fairfield.
Responding to another question, McMahon reflected on how her time as a wrestling industry executive prepared her for her current role. She joked that she can “give you a mean body slam,” then said on a more serious note she benefitted throughout her life by always being open to new opportunities.
She stressed the importance of having university programs that teach older workers new skills.
“How great is it that we have these opportunities to go in a different direction?” McMahon said. “Just be wide open. Don’t think that you’re limited in your opportunity to do things. Be willing to take it on.”
