At Mill Street Energy, we partner with clean and efficient energy providers to offer you competitive energy pricing. By aggregating industrial businesses, cities, and our portfolio of clients, we secure extremely competitive rates that we pass on to you. Our power is transmitted via the existing electrical infrastructure to your current utility provider—including National Grid, Eversource, Unitil, and others.
Your existing utility provider maintains all operational responsibilities: they'll continue managing meter readings, infrastructure maintenance, outage responses, and monthly billing processes. The transition to our service is seamless and comes with complete transparency—no enrollment fees, no hidden costs, and no penalties should you choose to discontinue service.
The enrollment process is straightforward and fully automated. Simply provide your name, service address, and utility account number, and we'll handle all administrative requirements. You retain full flexibility to terminate service at any time by contacting us via phone or email.
