FERC issues show cause order finding that the ISO-NE Tariff may be unjust and unreasonable because it lacks provisions that would enable ISO-NE to correct improper or erroneous payments or charges to market participants in ISO-NE’s markets (Correction Mechanism), directing ISO-NE to either: (1) show cause as to why the Tariff remains just and reasonable and not unduly discriminatory or preferential given its lack of a Correction Mechanism or (2) explain how it will revise the Tariff to remedy the identified concerns if the Commission were to determine that the Tariff has in fact become unjust and unreasonable or unduly discriminatory or preferential and, therefore, proceeds to establish replacement Tariff provisions.
