About Spire MoGas Pipeline

The Spire MoGas Pipeline is a 328-mile interstate natural gas pipeline system with service to markets in Missouri and Illinois. 

Spire MoGas Pipeline interconnects with multiple interstate transmission pipelines providing it's industrial and municipal end-users access to America's prolific and reliable supply basin. Its strategic location in the middle of the country provides access to 30 delivery points, interconnecting with several receipt points:

• Mississippi River Transmission Corporation (MRT)
• Panhandle Eastern Pipe Line Company (PEPL)
• Rockies Express Pipeline (REX)

NEW: Spire MoGas Pipeline now includes Spire STL Pipeline 

After receiving approval from the Federal Energy Regulatory Commission (FERC), Spire STL Pipeline and Spire MoGas Pipeline have merged, operating under one pipeline certificate, one tariff and one name – Spire MoGas Pipeline – while maintaining existing rates and service. This change became effective January 1, 2026. 

The pipeline includes the existing STL Pipeline infrastructure built and put into service by Spire in 2019 as well as MoGas Pipeline, which was acquired by Spire from CorEnergy Infrastructure in 2024.
