On October 20, 2011, FERC issued a Notice of Proposed Rulemaking (NOPR) to revise its regulations to require that each regional transmission organization (RTO) and independent system operator (ISO) electronically deliver data related to the markets they administer to FERC on an ongoing basis. The data, which is already being collected by the RTOs and ISOs, would encompass physical and virtual offers and bids, market awards, resource outputs, marginal cost estimate, shift factors, financial transmission rights, internal bilateral contracts and interchange pricing. FERC stated that the data would help with the development of its policies and regulations and assist in detecting anti-competitive or manipulative behavior or ineffective market rules. Agenda item E-4 may be FERC’s proposed Final Rule.
