This thesis contributes new knowledge about the effect of the gas grid on the power generation sector and how this effect could inform grid generation resource planning.
In chapter 2, I explore how reliability event reporting standards for operators of the natural gas grid compare to the requirements for power generators. Informed by a quantitative comparison of the numerical thresholds of reporting for gas grid and power generator failure events, I recommend a new reporting requirement for the gas grid that will bring it into line with the requirements for gas-fired power plant operators.
In chapter 3, I examine why gas-fired power plants in the United States have failed because of fuel shortages. I analyze six years of data from a database of power plant failures called the Generating Availability Data System (GADS). Using pipeline scheduling data, I identify areas of the natural gas grid where enough pipeline space may be available so that increased priority fuel contacts could help mitigate fuel shortages at gas-fired power generators.
Chapter 4 examines the economics of distributed fuel storage as a mitigation option for gas shortages at power plants in areas of the U.S. where pipeline space was not historically available. I estimate the additional costs required for New England gas-fired generators to install either distributed compressed natural gas (CNG) storage or oil dual fuel capabilities as fuel security measures at power plant sites. I construct fuel shortage mitigation supply curves using the cost estimates I develop. I also calculate simple payback periods of mitigation options using the cost estimates and foregone energy and capacity revenue stream estimates. I compare the costs of fuel storage options to those of battery storage and demand response incentives.
