The final basic cause that resulted in the failure is no working state monitoring signal and failure warning signal of power supply source of controlled silicon excitation device.

The contract, awarded to Thales Raytheon systems, covers the supply of the radar itself as well as related infrastructure (buildings, power source, communications and protection systems).

Windpower will remain an unpredictable power source, of course. But as Japan has recently been reminded, a bit more diversity of supply would not hurt.
