Residential, State Efforts for More Solar Increase

Molokai residents are eager to install photovoltaic (PV) panels on their roofs to reduce their energy bills and malama the environment. But current technology limits the amount of renewable energy that can be fed into the island-wide electricity grid while maintaining reliability of electric service, according to Maui Electric Company (MECO).
Because renewable energy is a variable source — solar, for example, only generates energy during the day — MECO says relying heavily on renewable sources can cause instability in electricity service. To solve this problem, utility companies, in conjunction with the state Public Utilities Commission (PUC), have established various threshold levels, also known as penetration limits, to regulate the amount of renewable energy on each circuit.…
