There have been reported continuing issues of foundation failure on wind turbines. This issue was given some focus in Højgaard A/S v E.On Climate & Renewables UK Robin Rigg East Limited and another [2017] UKSC 59, where a miscalculation in the strength of the turbines’ foundations resulted in approximately €26 m of remedial costs. In the end, despite having exercised reasonable care and skill, the contractor was found to be liable for breaching a warranty that the foundations would be “fit for purpose”.
