MAKING INFORMED DECISIONS
The number of design decisions that developers must make is vast. At times, such decisions must be based upon uncertain or incomplete data, leading to potentially sub-optimal solutions. Kinewell Energy’s innovative KLOC software can help calculate the optimised inter-array cable cost sensitivities to uncertain data, allowing for decisions to be better informed leading to an overall lower levelised cost of energy.
REVOLUTIONARY
The revolutionary KLOC software rapidly designs an optimised inter-array cable layout of an offshore windfarm based on the information it is presented with. By taking advantage of the software’s incredible speed and utilising it many times with slightly changed input data each time, the cost sensitivities of an optimised inter- array cable layout can be determined. Prior to the availability of the KLOC
software, such analysis was not possible due to the prohibitive time and cost of undertaking such a calculation.
CASE STUDY
In a recent case study of the currently operating 576 MW Gwynt-y-mor offshore windfarm, the cost sensitivities of moving the offshore substations was investigated. During the process it was found that value could be delivered by moving the West substation by 1.3 km. Overall the redesign returned a saving of £2.2m, or 3% of the installed cable cost, relative to what has been installed by the developer.
It is not just the substation location that can be considered however; any input data can be varied to see its impact on the optimised inter-array cable cost. That allows the cost sensitives of; turbine types, cable types, their installation costs based on seabed conditions, their electrical characteristics along with any thermal constraint derating requirements based on seabed conditions, and turbine and substation locations amongst others to be calculated. With constant input data and without considering the cost sensitivity to uncertainties, the KLOC software typically delivers savings in the region of £3m - £30m per GW of installed capacity.
