Telyon Secures Credit Facility From GDEV, Liberty Mutual

Telyon closed a corporate credit facility on August 4, 2026, provided jointly by GDEV Management, LLC and Liberty Mutual Investments. The facility amount, pricing, maturity, and security package were not disclosed.

The Connecticut-based commercial and industrial clean energy developer plans to use the facility to support continued growth and project execution across solar, battery energy storage, EV charging, and microgrids. Telyon already operates across 20+ U.S. states.

The financing matters beyond Telyon. GDEV Management is expanding its capital-solutions strategy for middle-market energy developers, while Liberty Mutual Investments participated through its Energy & Infrastructure team within Alternative Credit. Private credit is moving deeper into the machinery of the energy transition, where developers need capital structures capable of surviving the long trip from signed contract to operating asset.

And that is where this gets interesting. Clean energy has plenty of ambition. What it increasingly needs is financing built for execution.

What Happened

Telyon, founded in 2020 and based in Old Saybrook, Connecticut, secured a corporate credit facility jointly provided by GDEV Management and Liberty Mutual Investments. The parties announced the transaction on August 4, 2026.

No facility size was disclosed. That distinction deserves neon lights because GDEV has separately identified $40M–$75M as a target range for future corporate and asset-level transactions. That range describes GDEV's broader credit strategy, not the size of the Telyon financing.

The new facility supports Telyon's growth and project execution capabilities. Telyon develops behind-the-meter commercial solar, community solar, battery energy storage systems, EV charging infrastructure, and microgrids while managing development, engineering, procurement, construction, financing, O&M, and asset management.

That full-stack approach is more consequential than it sounds. Energy infrastructure has an impressive ability to turn 1 project into 17 separate problems involving permits, equipment, contractors, financing, utilities, customers, and somebody wondering why the spreadsheet suddenly has a red tab. Telyon's proposition is to keep more of that complexity under 1 roof.

Why Telyon's Credit Facility Matters

Corporate credit gives an energy developer something project-specific capital cannot always provide: flexibility around the operating platform responsible for creating and executing the projects.

Telyon has projects spanning 20+ states. A GDEV portfolio report previously cited Telyon engagement across 24 states and 50 MW of projects operating or under construction as of 2024. The company's customer universe includes schools, municipalities, government entities, big-box retailers, data centers, and fulfillment centers.

A featured Telyon project includes a 5.67 MW DC rooftop solar installation in North Randall, Ohio. That is the physical side of the story. The financial side is increasingly about making sure developers have enough institutional capital behind them to repeatedly turn opportunities like that into operating infrastructure.

For sophisticated operators, this is the part worth watching. The energy transition is not merely a technology deployment problem. It is a capital formation, underwriting, execution, and asset-management problem wearing work boots.

Telyon's Capital Story Did Not Start Yesterday

Telyon's financing history shows how clean-energy developers can evolve alongside their capital partners.

Telyon originated as Telos Clean Energy through a joint venture with the Goldman Sachs Alternative Energy Investing Group. The venture launched with an initial capital commitment of nearly $300M before Telos Clean Energy rebranded as Telyon in September 2020.

Greenbacker Capital Management added another layer in August 2023 by acquiring a significant minority equity stake in Telyon. Greenbacker's strategic partnership was designed, in part, to reduce traditional project-funding barriers and support nationwide project delivery.

Now GDEV Management and Liberty Mutual Investments are adding corporate credit.

The sequence matters: institutional backing, strategic equity, then additional credit capacity around a growing operating platform. Capital markets tend to become considerably more interested after a company proves it can convert financing into repeatable execution. Funny how investors develop excellent eyesight once operating evidence enters the room.

The Leadership Behind Telyon

Founder and CEO Andrew Chester brings 15+ years of renewable-energy experience to Telyon. Before founding the company, Andrew Chester was a Partner and Board Member at Greenskies Renewable Energy, where Andrew Chester executed hundreds of power purchase agreements and oversaw the financing, design, construction, and ongoing ownership of 100+ MW of solar projects.

Founding Partner and EVP of Business Development Mike Daly leads deal origination, strategic corporate partnerships, and brand development nationwide. Mike Daly previously led the National Accounts team at Greenskies Renewable Energy.

COO Robert Landino brings 35+ years of design, procurement, and construction experience, including 15+ years involving solar carport, rooftop, and ground-mount installations. Executive Director of Finance Bobby Landino manages project pricing, capital raising, budgeting, and reporting. EVP of Business Development Brian Dooley adds experience that includes helping launch and scale Target's onsite solar program.

Telyon's broader leadership also includes Director of Construction Robert Miller, Director of Human Resources Anne Demiris, and Director of Engineering Services Megan Bergen. The personnel mix explains part of the financing story. Infrastructure investors are not merely underwriting panels and batteries. They are underwriting organizations capable of originating projects, structuring contracts, raising capital, managing construction, and staying around after somebody turns the switch on.

Private Credit Is Moving Deeper Into Clean Energy

GDEV Management's involvement makes the Telyon transaction particularly useful as a market signal. GDEV describes itself as an infrastructure investor and private-equity platform focused on the middle market. The firm plans to expand its capital-solutions business across storage, solar, and broader energy infrastructure, targeting future corporate and asset-level transactions of $40M–$75M. Liberty Mutual Investments participated through the Energy & Infrastructure team within its Alternative Credit business.

Put those pieces together and the transaction becomes more than another clean-energy financing announcement. Institutional alternative credit is finding opportunities between conventional project finance and traditional corporate borrowing, particularly among middle-market developers that have operating histories but still need flexible capital to scale.

That matters because solar and storage markets are becoming less forgiving. Development pipelines are not cash. Interconnection queues are not operating assets. Signed agreements still have to survive procurement, construction, financing, commissioning, and the occasional encounter with reality. Capital providers increasingly have to understand that entire chain.

What This Signals for Telyon and the Market

Telyon's corporate credit facility suggests that financing sophistication is becoming a competitive capability in C&I clean energy.

The strongest developers increasingly need more than access to project-level capital. They need relationships across equity, corporate credit, asset finance, and long-duration infrastructure capital. Telyon's history with Goldman Sachs Alternative Energy Investing Group, Greenbacker Capital Management, GDEV Management, and Liberty Mutual Investments illustrates that progression.

Telyon also arrives at this financing with external markers of growth. The company appeared on the 2025 Inc. 5000 list of America's fastest-growing companies, while Andrew Chester was named a 2026 EY Entrepreneur Of The Year finalist for the New York region.

Awards do not build solar arrays. Neither do press releases. But recognition combined with geographic expansion, operating projects, institutional investors, and additional credit capacity starts forming a more useful picture. The market is rewarding developers that can make clean energy boring in the best possible way: finance it, build it, operate it, repeat.

The Bigger Industry Shift

Commercial solar, battery storage, EV infrastructure, and microgrids are converging into a broader distributed-energy market serving organizations with increasingly complicated power requirements.

Data centers need electricity. Retailers want cost control and sustainability options. Municipalities and schools face budget constraints. Commercial operators are confronting grid reliability, energy prices, electrification, and resilience at the same time. Telyon's portfolio sits inside that collision.

The opportunity for Telyon is therefore larger than selling another rooftop solar installation. A vertically integrated developer capable of combining solar, storage, charging, microgrids, financing, construction, and ongoing asset management can become an infrastructure partner to customers whose energy requirements are getting harder, not easier.

GDEV Management and Liberty Mutual Investments are placing credit behind that operating thesis without publicly disclosing the size of the bet. Sometimes the missing number is not the most important number. Watch the megawatts that follow.
