They had not correctly planned for outages to the wind turbine system caused by network system failures.

All generators turn off if there is a bad system failure: you can't keep running a generator if no customers are connected. The wind systems are particularly sensitive. The wind systems configuration was conservative, because they were configured to be operated as part of a coal-fired generating system. As part of a coal-fired system, they were configured to expect small deviations only when there was a general system failure. Without coal, they need to be configured to expect normal fluctuations are much larger and longer lasting.
