Since 2018 • Building Long-Term Partnerships

We Build More Than Energy Solutions. We Build Lasting Relationships.

At Mill Street Energy, we believe energy management shouldn't be complicated. What started as a mission to simplify energy procurement for New England organizations has evolved into a comprehensive partnership model that delivers measurable results while building enduring relationships.

We're different by design. While others treat municipal and commercial clients the same, we understand that a town's budget constraints aren't identical to a manufacturer's cash flow concerns. That's why we developed specialized approaches for each sector, ensuring compliance for public entities and operational efficiency for private ones.

Our commitment to zero upfront investment and guaranteed results isn't just a business model – it's a testament to our confidence in what we deliver. When our clients succeed, we succeed. It's that simple.
