The realization is dawning on the PUC that their goal of 100 renewable energy will increase electric rates significantly.  This should not be a surprise as that is exactly what has happened in Germany, Australia and Ontario, Canada. The result will be that not only homeowners but businesses, neighborhoods and entire communities will find it economically advantageous to leave the grid entirely.  Wind, solar and storage combined into a microgrid will be significantly less expensive than power provided by HECO.

Grid defection will force HECO to allocate fixed costs across a smaller pool of ratepayers which will increase rates causing more grid defection. The process will repeat itself endlessly as the cost of alternative power decreases while HECO's fixed costs increase.

“The risks associated with such decisions,” the commission concluded, “lies with the companies.”  Translation: Bureaucrats who have never run so much as a shave ice stand have no clue about the ultimate outcome.
