Title: III.b Hydroelectric power stations Costs Content: h1 Technologies costed in this sector * Hydroelectricity - Please click on: Hydroelectricity cost data h1 Costs Methodlogy h2 Methodology used The user defines the number of hydroelectricity capacity. Once the trajectory is set by the user, the number of plants to be built are defined. Investment costs are a function of new build and operating cost are a function of the number of plants operating within that time period. We assume turbines retire after 20 years and the cost of replacement is included. Please see 2050 Methodology for a full description of the costs approach in the Calculator. h2 Methodology issues and uncertainties * May need to revisit assumption on current stock retirement at 2050 * Output assumption in the Calculator appears conservative compared to other studies h1 Technical Assumptions * Lifetime = 60yrs, assume current stock and those built in 2010 doesn't retire until after 2050 or after but no other retirement over 2010-2045 * Load Factor = 38% * Input Fuel = Hydro h1 General Comments Please use this space to make any general comments.
