A break in the wind 25/26 November


The mark of a good wind farm is a steady consistent wind and that is exactly what we’ve had over the last few days. The WEC1 Turbine hub and blades had been ready for lifting since mid-day yesterday but wind conditions were well above the desired 8-9 knots. Frustration turned into delight when a window of calm air presented itself last night around 7:30pm. Johno Leitch mustered the team and by 8:30pm, the hub and blades had been successfully installed on the WEC1 turbine and the team back at Scott Base by 10pm.

The attached progress pics mark a key milestone for the team and we hope to have this turbine generating in the next 2-3 days. Erection of WEC2 turbine is scheduled to commence tomorrow.

In parallel with the success of the WEC1 turbine milestone, the Powercorp team successfully completed the testing and commissioning of the PowerStore flywheel system injecting 500kW of energy into the Ross Island network. This demonstrated the ability to provide voltage and frequency support for the McMurdo Station generators and to maintain system stability during transient conditions.
