Island power systems can reduce their reliance on diesel by successfully harnessing renewable resources such as wind, biomass, and solar. These resources have been successfully integrated into many island systems. Island power systems often have very high fractions of renewable energy.
Special emphasis is given to energy storage on islands, as a new contribution to earlier studies. Nowadays, with the large-scale penetration of distributed and renewable energy resources, ES (energy storage) stands out for its ability of adding flexibility, controlling intermittence and providing back-up generation to electrical networks.
On a utility scale, PHES (pumped hydroelectric energy storage) and CAES (compressed air energy storage) are the natural choice for large scale energy storage. From electricity market point of view they offer the highest economic feasibility, .
ARES (advanced rail energy storage) to harness the potential of gravity is under research in Santa Monica, California, this system requires specific topography and delivers more power for the same height to PHES and could achieve more than 85% efficiency. A demonstration system is being built, and should become operational in 2013.
The energetic mix will vary along the useful life of the hydro pumped storage power plant system. The maximum penetration of renewables will be reached in 2015 (77%). For the first two decades renewable energy sources will contribute with more than 75% of power needs.
Island energy systems are expensive due to several reasons, including the difficulties of fuel delivery and access for maintenance in remote locations. Apart from the economies of scale, these systems often have access to good renewable resources such as wind, biomass and solar resources.
