HALCHITA, Utah – After a five-year wait, Lorraine Black and Ricky Gillis heard the rumblings of an electrical crew reach their home on the sprawling Navajo Nation. In five days’ time, their home would be connected to the power grid, replacing their reliance on a few solar panels and propane lanterns. No longer would the CPAP machine Gillis uses for sleep apnea or his home heart monitor transmitting information to doctors 400 miles away face interruptions due to intermittent power. It also means Black and Gillis can now use more than a few appliances at the same time.
