Abstract

St. Brendan's is an isolated rural community in the north of New foundland. It has an installed diesel generated electricity capacity of 735 kW with an annual average energy consumption of 3185 kWh/day. The average annual wind speed in the area is estimated at 7.6m/s. This paper describes the primary design, simulation and pre-feasibility of adding wind turbines to the exiting diesel electrical system of St. Brendan's. Year round hourly power consumption data recorded in St. Brendan's are used for the selection and analysis of wind-diesel hybrid energy system. National Renewable Energy Laboratory's HOMER and Hybrid2 software were used to determine the best configuration of the wind-diesel system. Site data, system description and expected performance of the system are presented in this paper. The results indicate that retrofitting of diesel plants for St. Brendan's using wind turbines will result in significant fuel savings.
