The Hawaii Solar Integraion Study (HSIS) examined the operational impact of high penetrations of solar and wind energy on the Oahu and Maui bulk power systems. Evaluations included: reserve strategies, impacts on thermal unit commitment and dispatch, utilization of energy storage, renewable energy curtailment, and other aspects of grid reliability, operations and costs. The results showed that while Oahu’s grid could maintain reliability while integrating the amounts of variable renewable energy in the highest penetration scenarios, the Maui system would need to curtail most of any additional solar generation, in addition to the curtailment of wind that currently existed. The Maui analysis identifies sever curtailment mitigation strategies.
