The document outlines and ambitious goal to reach 100% renewable energy by 2040 (pg. 60). After considering the local factors and needs of the island, results are summarized in a roadmap that includes1,000kW-scale onshore OTEC as well as offshore OTEC of 5MW-scale.
In the roadmap (pg. 93) 1MW-scale is included in 2025, while the offshore larger-scale facility is included in 2035. In the final 2040 simulation, energy demand is expected to be supplied by a combination of OTEC, PV, and renewably sourced transportation such as EV, Biofuel, etc.
