This should help ...<br /><br /><a href="http://scottish.scienceontheweb.net/Wind%20power%20storage%20back-up%20calculator.htm" rel="nofollow">Wind, storage and back-up system designer</a><br /><br />Peak demand, wind and back-up power / energy usage and storage capacity calculator<br /><br />For the specification and design of renewable energy electricity generation systems which successfully smooth intermittent wind generation to serve customer demand, 24 hours a day, 7 days a week and 52 weeks a year.<br /><br />Adopting the recommendation derived from scientific computer modelling that the energy storage capacity be about 5 hours times the wind power capacity, the tables offer rows of previously successful modelled system configurations - row A, a configuration with no back-up power and rows B to G offering alternative ratios of wind power to back-up power.
