U.S. Energy Department Approves $1.6 Billion Loan for DTE Gas Infrastructure Upgrades

The U.S. Energy Department on June 15 finalized a $1.6 billion loan for DTE Gas Company to modernize natural gas infrastructure in Michigan, a move projected to deliver more than $700 million in savings for customers while improving the reliability of the state’s energy distribution system.

The financing, announced through the DOE’s Office of Energy Dominance Financing, will support the replacement and modernization of approximately 800 miles of natural gas distribution mains and service lines. The project also includes reconstruction of a compressor station that enables the utility to store natural gas during periods of lower demand and use those supplies during peak consumption periods, helping reduce fuel costs for customers.

The upgrades are expected to enhance the resilience of Michigan’s natural gas network by replacing aging infrastructure and improving system performance. The department expects that modernized delivery systems can reduce maintenance expenses, improve service reliability, and mitigate price volatility during periods of elevated demand.

The DTE financing follows a series of large-scale federal energy infrastructure loans aimed at improving reliability and lowering customer costs. In February, DOE approved a record $26.5 billion loan package for Southern Company utilities in Georgia and Alabama, projecting more than $7 billion in customer savings through investments in grid reliability and power generation. The department also finalized a $1.6 billion loan guarantee for American Electric Power in October 2025 to modernize transmission infrastructure across five states and support growing electricity demand.

The action underscores the administration’s continued use of federal financing tools to advance energy infrastructure projects viewed as critical to affordability, reliability, and long-term energy security.
