Title: III.c Tidal and Wave Costs

Content: h1 Technologies costed in this sector

* Wave turbine - Please click on: Wave Cost Data
* Tidal range/barrage - Please click on: Tidal Range Cost Data
* Tidal Stream - Please click on: Tidal Stream Cost Data

h1 Costs Methodology

h2 Methodology used

The user defines the number of wave and tidal turbines. 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 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 of 25 year economic life for wave and tidal stream (tidal stream and wave likely to be similar or less than offshore wind - tidal range will be much longer -eg La Rance which has been operating now for more than 40 years without any major refurbishment and with predictions for 80+ yers of further operation). 
* Need to check Tidal Barage costs against the studies reported in D11/1030385 (tidal barrage costs and lives are available from Severn, Duddon and Mersey Studies)
* Investment cost includes the cost of grid connection, need to make sure we don't double count the cost of an offshore grid or under-represent transmission costs

h1 Technical Assumptions

h2 Wave Turbine

* Lifetime =  25yrs[Average from Markal and ESME]
* Availability = 90% 
* Load Factor = 25%
* Input Fuel = Wave

h2 Tidal range/barrage

* Lifetime =  120yrs[ref Severn Tidal Power Study but also reinforced by other tidal range power studies including Mersey, Duddon and Solway) ]
* Availability = 95% 
* Load Factor = 20-24%
* Input Fuel = Tidal

h2 Tidal Stream

* Lifetime =  25yrs[Average from Markal and ESME]
* Availability = 90% 
* Load Factor = 30% (Ref SETS) 
* Input Fuel = Tidal
