Shelton-based energy-as-a-service company Budderfly announced it has secured another $100 million in financing from Nuveen Energy Infrastructure Credit.
The additional financing doubles Budderfly’s corporate debt facility to $200 million as the company continues to expand its energy-efficiency and infrastructure modernization business.
The latest investment brings Nuveen's total commitment to Budderfly to more than $300 million when project financing facilities are included, the companies said.
Budderfly officials said the company now has access to more than $1.1 billion in capital across equity, corporate debt and project financing vehicles.
The expanded financing builds on an initial $100 million corporate debt facility established in May 2025. The companies first partnered in 2024, and Nuveen has since increased its participation in both Budderfly's corporate and project financing efforts.
Budderfly said the proceeds will help expand its energy-efficiency projects for businesses nationwide.
The company installs and manages systems including heating and cooling equipment, lighting, refrigeration, building controls and water technologies under long-term service agreements.
Budderfly serves customers in industries including restaurants, retail, healthcare and manufacturing.
Nuveen Energy Infrastructure Credit, which invests in clean energy and infrastructure projects, said the additional financing reflects confidence in Budderfly's performance and growth prospects.
