On Monday Governor Janet Mills asked the Maine Public Utilities Commission(PUC) to open an investigation into why Central Maine Power is belatedly telling solar developers that their projects are causing technical problems at substations that in some instances could require multimillion-dollar upgrades.
Mills said she is especially concerned that some solar projects were already built and ready to operate. In her letter Governor Mills said she would like the PUC to start a broader review of Maine’s electric utilities to ensure they have the systems and planning to accommodate the growth of renewable energy generation.
Phil Bartlett, PUC Chairman indicated that he expects to start a formal proceeding regarding this matter in the next few weeks.
