SPP executives had “inappropriate” involvement in the oversight of its Market Monitoring Unit (MMU), FERC says in an audit report that calls for changes.

FERC effectively ended their 13-month inquiry of the SPP audit of MMU's independence without interviewing Oversight Committee Joshua W. Martin III.

SPP has interfered with the autonomy of its internal MMU, according to two former monitors who say they were fired for voicing their concerns.
