Wholesale electricity sellers that are not government owned are subject to regulation by the Federal Energy Regulatory Commission. Obtaining FERC approval to sell wholesale electricity at “market-based rates” (which is nearly any sale regulated under the Federal Power Act that is not based on cost-of-service accounting) can be an intricate exercise, requiring the applicant to submit statistical horizontal market power screens. Within the FERC-regulated organized markets, the independent system operators and regional transmission organizations (ISOs/RTOs), monitoring staff and procedures, and transparent real-time and long-term demand and pricing information have led many market participants to conclude that the required market power statistical screen studies are of little value and function merely as an administrative impediment to doing business. On July 18, FERC issued a final rule, Refinements to Horizontal Market Power Analysis for Sellers in Certain Regional Transmission Organization and Independent System Operator Markets, Order No. 861, that relieves market-based rate (MBR) entities of the statistical screen requirements in some—but not all—of the ISO/RTO markets. This should streamline both the regulatory approval process for prospective MBR entities and the ongoing compliance process for MBR entities that file notices, triennial renewal applications, and similar documents with FERC.
Order No. 861 relieves MBR entities (most of which are independent generating companies and/or power marketers, and some of which are traditional franchised utilities) of the need to prepare and submit statistical screen analyses if the MBR applicant or holder is within the Northeastern and Central ISO/RTO markets—that is, ISO New England, New York ISO, PJM Interconnection, or Midcontinent Independent System Operator. In these ISO/RTOs, FERC found that the existence of both capacity and energy markets and the vigor of market monitoring and mitigation were sufficient to permit applicants to dispense with the horizontal screen studies.
