FERC Conditionally Approves MISO Tariff Amendment on Cost Allocation

This afternoon, the Federal Energy Regulatory Commission conditionally approved the Midwest Independent Transmission System Operator’s (MISO) proposed tariff amendment regarding allocating the cost of network upgrades for generation interconnection projects meeting MISO’s regional expansion criteria and benefits (RECB) standards.  See my previous blog entry for a more detailed discussion on the history of the tariff amendment, as well as protests to the amendment filed by AWEA and others.

Under the decision rendered today, FERC found that the proposed solution provides an interim solution, and directs MISO to make a compliance filing (1) to fulfill its commitment to file superseding tariff revisions regarding the Phase II cost allocation methodology on or before July 15, 2010, and (2) to reflect certain conforming changes to its tariff.  In addition, FERC expects MISO to provide the Commission with status reports on the Phase II process.
