In ER20-588, FERC recently suspended for five months proposed changes to the MISO tariff to accommodate energy storage as a transmission asset. They ordered Staff to have a technical conference. Below is the key paragraph from the Order, which is attached.
- “Our preliminary analysis indicates that the proposed revisions to MISO’s Tariff have not been shown to be just and reasonable and may be unjust, unreasonable, unduly discriminatory or preferential, or otherwise unlawful. We find that MISO’s filing raises issues that cannot be resolved based on the record before us and are more appropriately addressed in a technical conference. Accordingly, we accept the proposed Tariff revisions for filing, suspend them for five months, to become effective on August 11, 2020, subject to refund, and direct Commission staff to hold a technical conference in this matter. Issues to be addressed include, but are not limited to, MISO’s proposed evaluation and selection criteria for SATOAs, the SATOA’s market activities and any potential wholesale market impacts of those activities, how MISO’s current formula rate structure accommodates cost recovery for SATOAs, a SATOA’s potential impact on the generator interconnection queue, and operating guides that will apply to a SATOA. Commission staff will include the details of the technical conference in a subsequent notice. Following the technical conference, parties will have an opportunity to file written comments that will be included in the formal record of the proceeding, which, together with the record developed to date, will form the basis for further Commission action.”
