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.
