    Excerpt from the Introduction:

    Thank you for the opportunity to participate in this technical conference. My comments here and during the conference are my own and do not represent the opinions of anyone else. The focus of my remarks will be on carbon pricing and the interactions with short-term electricity markets as found in the organized wholesale markets in the United States. I do not address the design and implementation questions focused on investments and resource adequacy that underpin capacity markets.

    FERC, Operator‐Initiated Commitments in RTO and ISO Markets, 2014.Abstract

    EXCERPT FROM THE EXECUTIVE SUMMARY:

     

    This paper is part of an effort to evaluate matters affecting price formation in the energy and ancillary services markets operated by Regional Transmission Operators (RTOs) and Independent System Operators (ISOs) subject to the jurisdiction of the Federal Energy Regulatory Commission (FERC or Commission). It focuses on operator-initiated commitments in the RTOs and ISOs and the challenges in internalizing all relevant physical and operational constraints in the day-ahead and real-time market processes. This paper defines an operator-initiated commitment as a commitment that is not associated with a resource clearing the day-ahead or real-time market on the basis of economics and that is not a self-schedule. Deeming an action to be “operator-initiated” is not intended to confer any judgment that the action is not appropriate or necessary to maintain reliability.

     

    FERC, Principles for Efficient and Reliable Reactive Power Supply and Consumption, 2004.Abstract

    EXCERPT FROM THE EXECUTIVE SUMMARY:

    Almost all bulk electric power in the United States is generated, transported and consumed in an alternating current (AC) network. Elements of AC systems produce and consume two kinds of power: real power (measured in watts) and reactive power (measured in volt-amperes reactive, or var). Real power accomplishes useful work (e.g., running motors and lighting lamps). Reactive power supports the voltages that must be controlled for system reliability.

    Reactive power supply is essential for reliably operating the electric transmission system. Inadequate reactive power has led to voltage collapses and has been a major cause of several recent major power outages worldwide. And while the August 2003 blackout in the United States and Canada was not due to a voltage collapse as that term has been traditionally used, the final report of the U.S.-Canada Power System Outage Task Force (April 2004) said that “insufficient reactive power was an issue in the blackout.” Dynamic capacitive reactive power supplies were exhausted in the period leading up to the blackout.

    Excerpt from the Introduction:

    Electric-industry restructuring has derailed. The massive blackout of August 14, 2003 certainly was not needed to underscore the point, but it adds urgency to the effort to find solutions. Wholesale markets continue to evolve slowly and erratically but are impeded by state- federal conflict, regulatory and legislative uncertainty, malfeasance, poor credit and outright collapses, of which Enron is only the most notorious. FERC’s efforts to promote more efficient markets through regional transmission organizations and a wholesale market platform offer promise, but have generated confusion and opposition. In the last five years, increased generation competition has elicited more than 100,000 megawatts of gas- fired peaking and baseload capacity, which has contributed both to a period of relatively low wholesale prices in many regions and increased exposure to gas price volatility across the system. But competitors’ losses have created substantial uncertainty about how quickly and on what terms capital markets will support additional investment throughout this sector. Indeed, investment in all categories of electricity infrastructure is down significantly, in part because of surplus capacity conditions in certain regions, but also because of uncertainty concerning which entities have the responsibility for identifying and making investments in the transmission and distribution networks, and uncertainties about how the associated costs will be recovered. A challenge in reviving these capital flows is to clarify prospects for cost recovery and reward: for example, when and on what terms will distribution utilities have the ability to enter into long-term contracts with generation service providers; how will distribution utility responsibilities interact with the opportunities created for competitive retail suppliers in states with retail competition; who has the responsibility for identifying needed enhancements to the transmission network; how will they be paid for securing them; and who will pay? The August 2003 blackout is a reminder of how much hinges on finding practical answers promptly.

    Excerpt from the Executive Summary:

    News of Enron’s accounting improprieties and subsequent collapse have been part of the continued eventful last two years for the electric supply industry. Shortly after the skyrocketing prices in California and the West of 2000 and 2001 had subsided, the Enron developments began to come to light in late 2001. This has lead to investigations by several federal agencies and revelations of improper trading and reporting practices of other energy companies. As a result of this and reduced demand for electricity, the industry has been hit by a “credit crunch” as investors have become more wary and has forced many energy companies to cut back on trading activities, sell assets, and reduce future investments in order to improve their balance sheets. In the face of all the industry turmoil, while many retail markets remain relatively inactive, particularly for smaller residential customers, overall market activity has increased from last year. Wholesale markets since California settled down, continue in general to function well from an operational standpoint, however, there continues to be strong evidence that significant market power is being exercised in all markets that have been examined.
