Renewable+storage integration for island power system

Brattle experts analyzed options to integrate renewable (wind, solar, and biogas) resources to provide 50% of the island’s electricity needs. The study included development of different ancillary service requirements, detailed operational simulations accounting for renewables and load forecast uncertainty and variability, generator maintenance and forced outages, economic cost, and benefit evaluations of renewable+storage integration. Several storage technologies were analyzed to improve renewable integration, including various capacity, energy density, different charging and discharging options, installation options, and ownership models. Brattle experts are currently analyzing options to avoid fuel-oil use for all energy and water production.
