The Interconnection Nightmare in Hawaii and Why It Matters to the U.S. Residential PV Industry

Since January 1, 2011, Hawaii’s three investor-owned utilities interconnected more than 250 MW of solar PV (almost two-thirds residential) to grids with aggregate peak loads around 1,500 MW. This boom ended five months ago when Hawaiian Electric Company (HECO) abruptly stopped approving residential net metering (NEM) applications for most communities on the island of Oahu. HECO claimed the grid was over-saturated with solar and that further study and infrastructure upgrades were needed to restart the interconnection process. The sudden shift left thousands of consumers stranded in “solar limbo” and caused large-scale lay-offs. Yet for all the media attention the ongoing fiasco has received, its primary lessons remain poorly understood.
