Natural gas is an affordable and reliable energy source. Federal facilities rely on natural gas for space and water heating, cooking, backup power generation, and even district heating. Understanding the state of your natural gas system, including both on-site infrastructure condition and utility infrastructure, is key to identifying the most impactful energy resilience solutions to ensure mission continuity. This training will provide an overview of natural gas infrastructure for facility resilience planning, including natural gas backup systems and demand flexibility systems that may result in energy cost savings and increased energy security.
