FERC has upheld its order that MISO and SPP fix their overlapping congestion charges on pseudo-ties despite a rehearing request from MISO.

FERC ruled last week that pseudo-tied loads and resources between MISO and SPP are subject to overlapping congestion charges.

FERC ordered a technical conference to investigate overlapping congestion charges imposed on pseudo-tie transactions between MISO and SPP.

FERC established briefing procedures for MISO and SPP as it investigates “overlapping and duplicative” congestion charges on pseudo-tie transactions.

SPP stakeholders discussed a recent AEP complaint filed at FERC against the RTO and MISO related to overlapping congestion charges for pseudo-ties.
