What our clients are saying:

"The Edison team is an extension of my own internal team, and a critical partner who understands our challenges and ambitions. Not only have they helped us implement decarbonization projects including procuring 60 MW renewables to date, identifying numerous energy reduction opportunities, and exploring fleet electrification, they have empowered us with better data, elicited unique insights about the emission hot spots and opportunities within our value chain (Scope 1, 2, and 3), and helped craft a vision and roadmap for achieving our net zero commitment. Edison’s technical acumen and strategic direction have been equally critical in supporting leadership discussions and driving alignment across the BMS."

- Victoria Emerick, Executive Director and Global Head, Corporate Sustainability Strategy and Operations, Bristol-Myers Squibb

"Edison Energy is my favorite consultant to deal with in any form. I’ve been working in corporate sustainability for 8+ years, and the professional world for 14. They have been unmatched in their support of our ambitious sustainability and renewable energy goals, which is why I’m taking the time to sincerely endorse them. The energy landscape is complex. The market is constantly evolving, processes can be very complicated, and the risks are HIGH; but Edison provides the expertise, the best analysis tools in the business, and the experienced team to get the project across the line, no matter the complications."

- Blair Sturm, Process Sustainability and Energy Manager, Saint-Gobain

"Edison Energy has been instrumental in helping The Home Depot enter the offsite renewable energy sector. We are grateful to have a partner with such a deep knowledge in the sector."

- Craig D'Arcy, Director of Energy Management, The Home Depot

"We have a small team in-house that works on our on-site generation projects, but we can’t do it all. Edison Energy is the bridge that GM was looking for to source large-scale renewable energy for our facilities."

- Rob Threlkeld, Global Manager, Renewable Energy, General Motors
