Sizing a Hybrid Power System for Battle Harbour Island in Labrador

摘要

Battle Harbour is a small island in the Labrador Sea just off the South East coast of Labrador. Presently, electricity is generated on Battle Harbour using a diesel generator when the island is populated for 3 summer months per year. Due to its remote location, the fuel cost on Battle Harbour is very expensive. In this research we look into on-site renewable energy resources and conduct a feasibility study of a hybrid power system for Battle Harbour. We present one-year recorded power consumption data, wind, solar energy and hydro resources of the island and discuss options for reducing diesel consumption. Two cases are considered, a) load as usual b) load reduced by 50% after energy conservation measures. The sizing of the hybrid power system for both cases is discussed. This feasibility study indicates that by using a hybrid power system the diesel consumption on the island can be reduced to one sixth of its present annual consumption.
