This approach is theoretically possible, but only if there is enough energy storage (approximately 10GWh) to match day-night solar fluctuations of over 3GW to a substantially flat ~800MW load curve and if grid stability can be mantained with dominant solar generation. The Renewables Portfolio Standard also covers only electricity generation, which presently supplies only about a third of Hawaii’s energy needs, so even if it’s met Hawaii will still fall well short of its 100% renewable energy target.
