As the company rapidly built its operating expertise, Founder Michael Polsky and then-COO Alex George began discussing expanding Invenergy Services to third-party facilities. The ultimate question was: who would build and lead the business? 

Then Director of Wind Operations Support Brad Purtell stepped forward. Brad had given over one hundred tours of the Invenergy Control Center in 2017 to customers, public officials, and partners; he was already selling Invenergy's operating capabilities daily and knew it could translate into an actionable business plan. He drafted the job description for a Director of Third-Party Services Business Development, then stepped into the role himself. 

The foundation was an "owner’s mindset": offering customers the same model proven across Invenergy’s fleet, while increasing standardization and buying power for parts and services. 

In 2019, Third-Party Services established the Field Service Major Corrective team, followed by the Field Services Blade Team in 2021. Starting with a few highly experienced managers and technicians, the teams have grown to include directors, managers, and over 75 technicians who conduct major corrective work and high-level blade repairs. To this day, their efforts are instrumental in providing partners with fast, adaptable onsite services, lowering operational risk, and continuously improving operating standards across our customers' fleets and our own. 

Throughout its history, Invenergy has prided itself on bringing innovative ideas across the business to life, resulting in major expansions and expanded capabilities that support responsible, reliable energy development and operations. The story of Invenergy Services' third-party expansion is no exception.

2018: Operating Beyond Invenergy

In 2019, Jessup, Pennsylvania, became home to Invenergy's largest operating energy plant: the Lackawanna Energy Center. Beyond its triumphant 1.5-gigawatt scale, Lackawanna holds a special place in Invenergy's history as a masterclass in modern energy efficiency, innovation, and community impact. 

Planning began as early as 2012, as older power plants across PJM retired and created opportunities for new natural gas generation. The initial concept was to develop a 1,370-megawatt facility into the side of a mountain near Scranton, Pennsylvania, using existing Invenergy equipment in storage. 

But in 2014, when interconnection studies revealed the site could support closer to 1,480 megawatts, Invenergy adopted General Electric's new-to-market 7HA.02 high-efficiency, air-cooled combustion turbines. This industry-leading technology would make Lackawanna an "H" class power plant: one of the most advanced, highly efficient natural gas generation facilities. 

Collaboration with GE was seamless, but construction brought challenges. Building atop a former coal mine on the side of a mountain required extensive rock excavation and mine-void mitigation before work could begin. The first-of-its-kind design also required phased commissioning, with one unit entering operation while the remaining units were still being completed. The entire process required careful planning and commissioning by a highly skilled, experienced construction team. 

"Invenergy's culture of innovation was instrumental in the success of a facility with the latest technology," attests Jason Carey, VP of Operations. Lackawanna became the first GE single-shaft H-class plant to reach commercial operations in the U.S. and remains the leader of GE's single-shaft fleet today. The project earned Power Magazine's Top Plant Award in 2019, while Engineering News-Record recognized EPC partner Kiewit with Best Energy/Industrial and Excellence in Safety. 

funded an annual scholarship through Lackawanna College for the last decade

, contributes $1 million each year to Jessup through a community host agreement, and supports local emergency services, educational programs, environmental organizations, and veterans' groups.

2019: A 1.5-Gigawatt Triumph

Geothermal energy is having a moment. Long confined to a handful of naturally hot, water-rich locations, the technology is now being reimagined with drilling techniques borrowed from the oil and gas industry— and Invenergy is positioning itself at the center of that shift.  

We sat down with James Murphy, Senior Vice President of Development, to unpack what Invenergy is building, why now, and what sets the company apart in this fast-emerging space. 

For people who don't work in energy every day, what is geothermal?

When most people think of renewable energy, they picture wind turbines or solar panels. Geothermal works differently. It taps the Earth's natural heat to generate 24/7 electricity. Our approach involves drilling wells more than 12,000 feet down into granite formations where temperatures exceed 400°F, then circulating fluid through that hot rock to bring the heat to the surface and convert it into power. 

The industry calls this an "enhanced geothermal system," or EGS, because instead of relying on naturally occurring hot-water reservoirs, we're engineering the system ourselves — essentially building a giant underground radiator in rock that wouldn't otherwise release its heat on its own. 

How big is Invenergy's geothermal footprint today?

We've moved quickly. Invenergy has assembled a portfolio of nearly 20 geothermal projects across Idaho, Nevada, Utah, New Mexico, and California, representing multiple gigawatts of potential generating capacity or enough to power millions of homes. We're now one of the largest federal geothermal leaseholders in the country, with more than 151,000 acres under lease. This year alone, we secured over a gigawatt of interconnection queue positions.  

We were also recently selected by the Department of Energy’s Office of Geothermal for a 

 that will help us advance exploratory drilling at one of our most promising large sites in Idaho.  

Geothermal has existed for decades. Why is it suddenly attracting so much attention?

It really comes down to a convergence of factors. Advances in drilling and subsurface technology mean we're no longer limited to searching for pockets of hot, briny water near the surface. In many places, especially west of the Rockies, there's extremely hot rock deep down. By adapting the same drilling techniques the shale industry pioneered, we can now access that heat at a cost point and a scale that simply wasn't possible before, and it happens to be perfectly positioned near growing power demand. 

On top of that, demand for clean energy is growing at scale, and geothermal is one of the few resources that can deliver true, around-the-clock baseload power with a carbon-free profile. That combination has both parties in Washington, utilities, and large energy buyers paying close attention. 

What gives Invenergy a real competitive advantage as more companies enter the geothermal space?

The market is splitting into two camps: those with a deep understanding of drilling and geology and others who lack the depth of power market experience to deliver a fully integrated solution on their own. 

Invenergy sits in a rare position to bridge that gap. We've spent 25+ years developing power infrastructure, and we already have the relationships with customers, transmission providers, investors, and communities that this industry needs to scale responsibly. Our goal is to combine our deep power-market expertise with world-class subsurface partners to execute. That combination is genuinely hard for either camp to replicate alone, and we’re excited about our future with this technology. 

How are you leveraging Invenergy’s existing expertise to pursue a new technology for the company?

This is honestly one of the things I'm proudest of. So much of our early progress has come from teams that already exist across the company – development, project management, engineering and construction services, GIS, interconnection, government and regulatory affairs, finance, legal, and communications have all played a huge role in laying the foundation. We're layering in specialized talent like geoscientists and subsurface professionals, but we're building geothermal the Invenergy way, leveraging the same organizational strengths, community relationships, and disciplined development process that have made the rest of our business successful.  

Geothermal can also integrate with solar, battery storage, transmission, and potentially thermal energy solutions, allowing us to combine multiple technologies into one energy platform. That is something very few companies in this space can do at scale, and a big part of why we're excited about where this goes from here.

Tapping the Earth's Heat: A Q&A on Invenergy's Geothermal Strategy with James J. Murphy

Last week, we welcomed financial partners to Chicago for our biennial Financial Partners Conference. As we celebrate our 25th anniversary, the event gave us a chance to reflect on the partnerships, disciplined execution, and growth that have shaped our company. Conversations focused on the opportunities ahead, the evolving energy landscape, and the role trusted financial partners continue to play in supporting the development of critical energy infrastructure. Since our founding, we have raised more than $80 billion in capital to support projects across our business, including $25B in the last three years alone. 

 This milestone reflects not only the significant growth of our business, but also the confidence our financial partners have placed in our ability to execute and deliver results.

Take a look at a few highlights from the event below. 

DSC03922.jpg

Invenergy’s Financial Partners Conference 2026

When Mexico reimagined its energy future in the mid-2010s, Invenergy stepped in to help build it. 

Invenergy established its presence in Mexico in 2014, drawn by the country's long-term potential at a moment when energy reforms were reshaping the power sector and opening new opportunities for private investment. Starting with a local partner and now operating independently, Invenergy brought its U.S. development and technical expertise to build a platform tailored to Mexico's unique energy needs. 

What followed was more than a decade of growth and innovation. Invenergy developed an expansive portfolio of natural gas, wind, solar, and battery storage, as well as tailored cogeneration and trigeneration solutions for industrial customers. Projects like La Toba, Mexico's first hybrid solar and storage project, demonstrated how innovative solutions could support reliability in isolated regions. Los Ramones, a 604.5 MW natural gas peaking facility in Nuevo León, strengthened the grid in one of the country's most important industrial hubs. 

Invenergy has developed nearly 900 MW of reliable energy since entering Mexico over a decade ago. Over the last 25 years, the company's approach to international development has reflected our core strengths: adapting to new markets, understanding local needs, and delivering solutions that make a regional difference

2014: Invenergy Enters Mexico's Energy Market

December 2013 marked a milestone in Invenergy’s history that solidified a long-standing truth: our ability to deliver is powered by our people.

In a single quarter, teams across the company successfully executed eight major project financings and transactions, representing more than $1 billion in activity across North America and Europe.

Invenergy had already spent a decade building expertise, refining processes and developing a culture focused on execution. By 2013, the company had proven it could successfully manage large, complex transactions – what made that December different was the sheer volume.

Multiple financings, refinancings, equity fundings, and project milestones all converged at year-end, requiring extraordinary coordination across finance, asset management, project management, legal, treasury, accounting, insurance, and many other teams. With holiday schedules approaching and critical deadlines looming, employees across the company worked together to keep every detail moving forward.

Andrea Hoffman, EVP of Global Risk, recalls that there were no plans to celebrate the achievement—as everyone was focused on executing their closings—until CEO Jim Murphy (then President) invited the team into his office to recognize what they accomplished. "It was really only at that point that the project financing list was written on the whiteboard...and we collectively recognized the accomplishment: about $1 billion in financial closings."

Twelve years later, the projects have changed, and the company has grown, but the formula remains the same: talented people, deep expertise, and a commitment to getting the job done.

It's a legacy of execution that’s driven Invenergy since the beginning, and will continue to do so for the next 25 years and beyond.

2013: 8 Major Project Financings in One Quarter

Michael Polsky Joins U.S. Secretary of Energy Advisory Board, Attends First Meeting in D.C.

Invenergy Founder and Executive Chairman Michael Polsky recently participated

in his first meeting as a member of the U.S. Secretary of Energy Advisory Board (SEAB), after being appointed in 

. SEAB provides independent advice and recommendations to the U.S. Secretary of Energy on a broad range of energy, science, technology, and national security issues. 

During this week's meeting in Washington, D.C., board members discussed key issues facing the U.S. energy sector, received updates from Department of Energy leadership, and provided input on matters important to the nation's energy future.

Polsky joins a distinguished group of leaders representing a range of energy, technology, and industrial organizations.

An engineer by training, Polsky’s career spans over 45 years and almost every form of energy. Beginning with coal, he worked in oil, nuclear, and natural gas power generation before founding and building two successful independent power companies, which developed cogeneration and gas plants. In 2001, Polsky founded his third company, Invenergy, playing a critical role in the global expansion of power generation at scale.

To learn more about the Secretary of Energy Advisory Board and its members, read the Department of Energy's announcement:

In 2008, Invenergy completed the first phase of a project that would shape the company's multi-tech energy approach.

Building on Invenergy's innovative, adaptive spirit, Grand Ridge Energy Center was the starting point for a new approach to energy development and the genesis of Invenergy's first solar and battery storage projects.

The Grand Ridge site – with an existing grid interconnection and abundant available land – was ideally positioned within Invenergy's growing renewable energy portfolio. Just as importantly, it offered an opportunity to think beyond a single technology and explore how different energy resources could work together to improve site productivity and reliability.

In 2012, Invenergy completed its first solar project at Grand Ridge. By adding solar generation alongside wind, the site's energy capacity and reliability increased, and the development timeline and construction costs were significantly reduced.

The company took it one step further and completed the Grand Ridge Storage Energy Center on-site in 2016. The project provided additional grid stability and served as the blueprint for Invenergy's future battery storage fleet, a portfolio that is now 5,000 megawatt-hours strong.

As it evolved, Grand Ridge became more than a project: it became a model for Invenergy's portfolio and philosophy. The lessons learned there helped shape the company's belief that the grid is best served when multiple energy technologies work together. Wind, solar and storage at Grand Ridge demonstrate how complementary resources can deliver greater reliability, efficiency and value than any single technology alone.

Grand Ridge also continues to reflect something equally important: the culture built by the people who operate it. More than a decade after the completion of its final phase, Grand Ridge's employees remain committed not only to maintaining, but continually improving the facility and finding new ways to excel.

That sense of pride and ownership is evident to Drew Foes, Grand Ridge's senior O&M manager.

"At the end of the day," Drew says, "it feels good to be part of a project with this much history and to know that the work we do every day matters, not just for Grand Ridge, but for Invenergy and the communities we help serve."

Twenty-five years after Invenergy's founding, Grand Ridge remains a powerful example of how innovation, collaboration, and a willingness to challenge conventions can create a lasting impact.

2008-2016: The Evolution of Grand Ridge Energy Center

"It's all about relationships in this business." — Jim Murphy, Co-Founder and CEO, Invenergy

After 25 years of building energy and infrastructure projects, Invenergy Co-Founder and CEO Jim Murphy believes the most important lessons have little to do with any single technology or market trend. Instead, they center on the fundamentals: earning trust, delivering results and solving complex challenges through strong partnerships and execution.

Since its founding in 2001, Invenergy has developed more than 225 projects representing nearly 40 gigawatts of generation and infrastructure capacity. While technologies, markets, and customer needs have evolved, Murphy emphasized that strong relationships remain central to the company's success just recently at the Reuters Global Energy Forum. Relationships with customers, suppliers, investors and communities help create the trust needed to navigate challenges and deliver projects over the long term, Murphy said.

Murphy also highlighted execution as a key differentiator, describing strong execution as an "underpriced asset" in today's marketplace. Throughout its history, Invenergy has taken on complex challenges across generation, transmission, manufacturing and infrastructure, relying on technical expertise and innovation to turn ideas into results.

The conversation also touched on what lies ahead. While the energy landscape continues to evolve, Murphy reiterated Invenergy's longstanding commitment to finding practical solutions to meet customer needs and support growing demand. Throughout the discussion, he emphasized that success starts with understanding the challenge, building the right partnerships and delivering on commitments.

As Invenergy marks its 25th anniversary, these reflections serve as a reminder that  the foundations of the company's success have remained remarkably consistent: strong relationships, disciplined execution and a willingness to tackle complex problems.

25 Years of Building: Jim Murphy Reflects on Invenergy's Growth

In honor of Invenergy's 25th Anniversary, we're looking back at the projects, people, and milestones that have helped make Invenergy North America’s largest privately held independent power producer and energy infrastructure innovator.

As Invenergy expanded its early portfolio of wind projects, the team recognized an opportunity to raise the standard for how those assets were operated. While the projects were supported by their original equipment manufacturers, Invenergy sought to bring the same operational discipline and accountability that had defined its natural gas business to its renewable fleet. 

Invenergy began building its own operations platform, Invenergy Services, from the ground up. In 2007, the company developed and took over operations at the Camp Springs Energy Center in Texas, launching its first Remote Operations Center (ROC) in an extra conference room in the O&M building. It had four computers: one for each of Invenergy’s wind sites. 

From its humble beginnings, Services rapidly evolved. The company invested in local, site-based teams, advanced training programs, and centralized monitoring capabilities that provided real-time insight into performance across its growing portfolio. The business effortlessly adopted a differentiated, owner-operator model that bolstered reliability, efficiency, and accountability. 

Services scaled globally alongside the company’s development business. From early international projects in Poland to expansion across Canada, Latin America, Europe, and beyond, the team built the operational expertise to support projects across diverse markets and technologies. 

Today, Invenergy Services is central to how Invenergy delivers energy solutions: combining hands-on operational experience with a relentless focus on performance to ensure projects produce reliable, efficient power for customers and communities around the world. 

It’s a model rooted in innovation, shaped by experience, and proven through execution—25 years in the making.

2007: The Origin of Invenergy Services

Over the next ten years, United States electricity demand is expected to grow 20-40%, a rate not seen in more than 20 years. To meet that demand, Invenergy is sharpening its focus on investment opportunities that can deliver reliable, affordable power for customers. 

“At a time of unprecedented energy demand, Invenergy is focused on delivering reliable, affordable energy for our customers and supporting disciplined investment at scale. That is why Invenergy, with our affiliates and on behalf of our various stakeholders, will deploy additional capital into projects that can be delivered on a commercially reasonable timeline and meet customer demand while continuing to evaluate opportunities as market conditions evolve,” said Daniel Runyan, Invenergy’s Senior Vice President for Development.

Invenergy will conclude its four offshore wind leases, receive a partial refund of capital previously paid to the government and deploy capital into additional domestic natural gas-fired projects in a multitude of states including Indiana, Wisconsin, Iowa, Kansas, and Missouri and geothermal power generation projects in the Western U.S. The approach will bring more megawatts to the grid and advance projects that can move forward today. These projects are expected to create hundreds of American jobs, reinforce grid reliability, and strengthen energy security on an accelerated timeline.

As an American company that has developed more than 225 projects representing 38 gigawatts of power infrastructure, while also operating more than 25 gigawatts today, Invenergy brings a proven record of energy innovation and trusted execution. The company will continue to evaluate opportunities as market conditions evolve, with a focus on advancing projects that can deliver reliable, affordable power to customers.

Getting More Megawatts onto the Grid

In a 2004 bankruptcy proceeding, Invenergy had the unique opportunity to acquire the Nelson Energy Center, an Illinois-based natural gas plant that was only partially completed. Invenergy recognized the project’s long-term value in selling power to the wholesale market, but reviving the operation would prove challenging. 

At the time of acquisition, only one out of four intended gas turbines had been delivered and installed. The plant had room for three additional turbines, but this was still more than double what the site needed to operate in its current market. 

At the same time, Invenergy had also entered a bidding process to build a gas plant in Ontario, Canada. The equipment otherwise needed at Nelson was exactly what the RFP asked for – a rare opportunity to efficiently leverage Nelson's efforts and resources to develop an additional energy project at the St. Clair site. 

Executing this vision required unprecedented coordination, careful deconstruction, and cross‑border planning. By reusing critical equipment already in fabrication or partially installed, Invenergy minimized material waste, reduced the need for new manufacturing, and accelerated the development of a modern power plant tailored to regional demand. The sister plants of Nelson and St. Clair ultimately became a testament to how flexible thinking and a solutions‑oriented culture can transform complexity into a smarter, more cost-efficient energy outcome. 

St. Clair achieved commercial operations in 2009. In 2026, St. Clair has retained nineteen of its original staff members, and as of May 2026, has reached commercial operations on a plant upgrade, significantly increasing its capacity and efficiency. 

Nelson restarted construction in 2013 and reached commercial operations in 2015. Invenergy later completed a 380-megawatt expansion to Nelson in 2023, bringing the total generation of the St. Clair Energy Centre and Nelson Energy Center to 1,634 megawatts.

Shaping the Future of Geothermal Power Generation in the Mountain West

Today’s power grid requires a mix of energy technologies to meet rising demand. Geothermal power, including enhanced geothermal systems, can unlock a secure domestic energy source that’s available 24/7. 

For 25 years, Invenergy has been at the forefront of developing innovative energy solutions for our customers. Our approach to geothermal is no different. Because of our longstanding track record of innovation and execution, Invenergy has been selected to drive the geothermal future as a formal advisor to the 

The Consortium is a new multi‑state organization of public officials, developers, utilities, offtakers, and other interested stakeholders focused on accelerating the deployment of geothermal power generation across the region.   

“Invenergy’s involvement in the consortium reflects our growing leadership in geothermal development and strengthens our relationships with state energy offices and regional partners. It’s an exciting opportunity to contribute our expertise and help advance a technology with significant long-term potential to be a secure, reliable and clean resource,” said James J. Murphy, Invenergy’s SVP for Development overseeing the company’s geothermal efforts. 

The group brings together industry and State Energy Officials from Colorado, New Mexico, Utah, Arizona, Nevada, and Idaho to coordinate regional strategies that can expand geothermal development. Their work includes strengthening the knowledge base for early‑stage investment, designing high‑impact interventions to grow the project pipeline, improving technical understanding among utilities and regulators, and aligning regional programmatic requests to funding authorities.  

The Consortium is currently in an information‑gathering and program‑design phase, with implementation expected later this year. Advisors will play a targeted role by:  

Invenergy’s growing geothermal work adds to its industry-leading portfolio of energy infrastructure, including natural gas, solar, land-based wind, energy storage, transmission, and domestic manufacturing. 

“Geothermal power generation is one of the most exciting new parts of our industry-leading technology portfolio. As an abundant, domestic resource that’s available 24/7, geothermal can help us meet growing energy demand from our customers,” Murphy concluded. 

Invenergy Joins the Mountain West Geothermal Consortium

In Invenergy’s earliest days, success depended on more than vision—it depended on proof.

The early 2000s were a period of rapid change in the U.S. energy market: volatile power prices, shifting ownership structures, and a growing need for scalable, disciplined project development. From the outset, Invenergy’s founding team understood that navigating this environment would require moving decisively when the right opportunities emerged, and exercising patience when they did not.

That opportunity arrived in 2003 with Hardee Energy Center, a 370-megawatt natural gas power plant that began operations in 1993 in rural Florida.

Our founding team, with deep expertise in gas-fired generation and operations, recognized that Hardee was a durable asset in a market still finding its footing. They moved forward deliberately, relying on long-standing relationships with partners and advisors who trusted their technical judgment and disciplined approach to ownership.

For those partners, the plant became an early signal of how Invenergy would operate, from prioritizing long-term performance to adopting innovative staffing structures.
