摘要

Uncertainties surrounding the continued operation of older coal generation units, the increased penetration of renewable resources, and the aging or retirement of certain nuclear units have exposed vulnerabilities in the natural gas supply chain. The increased availability and low price of natural gas for electric generation in many parts of the United States compounds them by increasing the economic pressure on various non-gas-fired base-load generation plants. Our growing dependence on natural gas as a primary fuel for electricity generation offers environmental and efficiency benefits, but it also presents operational challenges for independent system operators (ISOs) and regional transmission organizations (RTOs) that depend on the natural gas pipeline and storage network to facilitate reliability objectives. During the peak heating season, pipeline congestion can result in interruptions of gas deliveries to those gas-fired generators lacking primary firm entitlements. Scheduling restrictions associated with the provision of nonfirm transportation for gas-fired generators stress the capability of the electric system to meet demand and maintain operating reserves, as RTOs must quickly replace output from more efficient natural gas-fueled combined-cycle plants and quick-start peakers to maintain electric reliability. In this article, we address the gas-electric interdependencies across the Eastern Interconnection that are the subject of a multitarget research project sponsored by the U.S. Department of Energy (DOE) with the participation of PJM Interconnection, Midcontinent Independent System Operator (MISO), New York Independent System Operator (NYISO), ISO New England (ISO-NE), TVA, and the Independent Electricity System Operator of Ontario (IESO), collectively known as the participating planning authorities (PPAs).
