Who We Are

For Mainers, by Mainers.

Dirigo Solar was founded in 2015 and within six months was awarded the largest solar contract in the history of the Maine Public Utilities Commission.

The rapid growth of our venture required an expanded team with a  track record in large scale solar. In 2017, we selected BNRG Renewables based in Dublin, Ireland – a proven leader in utility scale solar both in the EU and the US. Together, Dirigo and BNRG formed a joint venture, BNRG Maine, LLC, which develops and finances the PUC portfolio as well as other projects in the development pipeline.

A lawyer turned entrepreneur, Bob began his professional career at the U.S. Department of Justice, where he prosecuted white collar crime as part of DOJ’s Honor Program. Following a career in private practice, he joined Wheelabrator Technologies and was instrumental in helping to shape environmental attribute tracking systems in ISO-NE and PJM. He ran the Washington, D.C.-based Biomass Power Association from 2008 to 2019, and played a lead role in expanding Section 45 production tax credits, accessing alternative fuel programs (LCFS and RFS) for the biofuels industry, and engaging with EPA, states and NGO’s on carbon policies both in the US and abroad. He is passionate about deploying sustainable, cost-effective energy solutions to help grow Maine’s rural economy.
