Advanced Microgrid is also privately held, but has several high-profile projects under its belt already. The company already has a sales presence in four states. Its track record includes what the company calls Hybrid Electric Building projects at California State University and Morgan Stanley, among others. Advanced Microgrid may have used its win in Massachusetts to impress investors in a Series B funding round just completed in early July 2017. Energy Impact Partners, a utility-funded investment firm, led the deal. DBL Partners, which led an $18 million Series A round in 2015, also participated.
None of these four companies likely provide immediate investment opportunity for minority investors. However, as private companies expand geographically, it is often necessary to gather financial support as can be observed in the venture rounds recently completed for eCurv and Advance Microgrid. It makes sense to put all four names on a watch list for that time when expansion opens the door to minority investment. Advanced Microgrid and Ice Energy might even become ready for initial public offerings if business scales as planned. All four companies have been added to the Efficiency Group in our Mothers of Invention Index of energy alternatives companies.
