Isle au Haut residents plan to install a sophisticated microgrid this spring that could eventually end their reliance on expensive power and heating fuel from the mainland.As on many of the other 14 Maine islands inhabited year-round, Isle au Haut residents pay at least double the amount a Portland or Bangor resident would for their electricity, kerosene and oil. Compounding matters, an aging undersea electric cable between Stonington and the island could fail any day, according to Jim Wilson, president of Isle au Haut Electric Power Co.
