Energy Infrastructure Modernization

Energy Infrastructure Modernization

Natural Gas

The nation's natural gas infrastructure transports gas to homes, buildings, industrial customers, and utilities for use in heating and electric power. Public utility commissions are responsible for assuring the safety, reliability, and efficiency of the natural gas distribution network.

The U.S. Department of Energy (DOE) and NARUC established a Natural Gas Infrastructure Modernization Partnership (NGIMP) as a cooperative effort to understand emerging technologies and regulatory options for improving commission oversight of natural gas utilities. The NGIMP convened state regulators, federal agencies, and other natural gas stakeholders to learn more about emerging technologies pertaining to critically important issues around enhancing infrastructure and pipeline safety. A particular focus is on natural gas pipeline leak detection and measurement tools, and learning about new technologies and cost-effective practices for enhancing pipeline safety, reliability, efficiency, and deliverability.

As of July 1, 2020, NARUC and the DOE launched a new Natural Gas Partnership (NGP) to replace the NGIMP. The NGP continues the NGIMP's work on leak detection and infrastructure modernization and broadens NARUC's focus to a broad range of issues relating to natural gas regulation. 

NGP activities are closely coordinated with the NARUC Committee on Gas

  • Artificial Intelligence for Natural Gas Utilities: A Primer, October 2020
    Artificial intelligence, machine learning, predictive analytics, and other applications of data analysis and statistical methods show great potential for improving the efficiency, reliability, and safety of the nation's natural gas infrastructure. In this resource, NARUC defines relevant terminology in this area and summarizes relevant applications and case studies for natural gas distribution utilities.
  • Natural Gas Distribution Infrastructure Replacement and Modernization: A Review of State Programs, January 2020
    Natural gas is an essential fuel for the U.S. economy, providing fuel for heating, electricity, and other services to customers. However, natural gas delivery infrastructure is aging, and technologies that were novel at the time of installation may no longer hold that position. Commissions and state legislatures have instituted a number of policies and regulations setting forth objectives and methods to remove and replace aging infrastructure. This report summarizes infrastructure replacement statutes and regulations in 41 states and the District of Columbia, with the goal of enhancing coordination across states and sharing best practices. While there is no perfect model program, state regulators can benefit from an understanding of the regulatory and infrastructure context in their states and how other states have implemented infrastructure replacement programs.
  • Sampling of Methane Emissions Detection Technologies and Practices for Natural Gas Distribution Infrastructure: An Educational Handbook for State Energy Regulators, July 2019
    This handbook summarizes methane leaks in the context of the natural gas distribution network. It identifies existing and emerging technologies and practices and outlines partnerships to further the development of novel tools. As a product of NGIMP, this research is primarily meant to expand state energy regulators’ understanding of state-of-the-art methane leak detection tools, thereby enhancing their ability to appropriately regulate the safety and efficiency of the nation’s natural gas infrastructure. However, multiple stakeholders including federal regulators, natural gas producers and utilities, consumer and environmental advocates, and others may also benefit from increased awareness of this market and its regulatory environment.
  • LNG: A Local Market – A Global Market - An Introductory Handbook for State Public Utility Commissioners, November 2018
    Liquefied natural gas (LNG) continues to play a significant and important role not only in the United States market, but also globally. LNG is viewed by many market participants as a viable asset to help expand the use of natural gas and support environmental policies striving to reduce the volume of CO2 and other pollutants that are emitted in the atmosphere by human activity. In its over 50-year-history of being traded, LNG has fostered alliances and become a vital source of revenue to producing regions. LNG has helped consumers in many regions reduce their carbon footprint and enjoy an energy source not bound by agreements entered into by a handful of producers. Technological advances have propelled LNG from a fuel used under extreme conditions, such as a cold spell, to a fuel that can be produced, transported, stored, and delivered safely to consumers for a broad range of applications, ranging from vehicular fuel to power generation. This handbook is intended to serve as an introductory tool for regulators and other interested readers to understand the basics behind the LNG market today and facilitate a thoughtful discourse between producers, regulators, and consumers for further appropriate and responsible engagement and communication on the path forward.
