Delivering essential energy

The Spire STL Pipeline is a critical source of energy  for more than 650,000 Missouri homes and businesses. 

Critical infrastructure

Without the state-of-the-art infrastructure and stable access to energy provided by the Spire STL Pipeline, up to 133,000 customers could have been without gas service during Winter Storm Uri. 

Reliability

The Spire STL Pipeline ensured that Missouri customers had access to affordable energy supply during Winter Storm Uri. Without the pipeline, overall Spire Missouri customers could have experienced additional gas costs of up to $300 million over the course of nine days.

What is the Spire STL Pipeline?

STL Pipeline is critical energy infrastructure that more than 650,000 Missouri residents and businesses rely on for reliable and affordable natural gas service. The STL Pipeline project was approved after a thorough and rigorous regulatory review and was designed and constructed to uphold Spire’s commitment to the environment and communities. Losing the STL Pipeline would have a detrimental impact on the health and safety, property and economic prosperity of the St. Louis region. 

Has the STL Pipeline helped the St. Louis region?

STL Pipeline ensures peak energy demands can be met in the heart of winter for the entire St. Louis region. STL Pipeline more than proved its worth as critical energy infrastructure during the extreme cold weather the U.S. experienced during Winter Storm Uri in February 2021. 

While natural gas production in the U.S. declined by roughly 25%, mostly driven by declines in Oklahoma, Texas, and Louisiana, production in the Rockies and Appalachian Basins that fed STL Pipeline saw little to no impact. As a result, Spire Missouri was able to continue providing reliable service to its customers in the St. Louis region during this unprecedented weather event. Without Spire STL Pipeline, Spire Missouri projected that at least some customers would have lost gas service on eight of the nine days from February 11, 2021 to February 19, 2021, with a peak of roughly 133,000 customers without service on February 15, 2021. Notably, that day was still 13 degrees warmer than Spire Missouri’s planned peak day.

Spire Missouri customers realized up to $300 million in gas cost savings over the course of nine days during Winter Storm Uri because STL Pipeline delivered gas supply sourced from the Rockies and Appalachian Basins, instead of the significantly higher-priced gas from the Texas producing basins where wells and lines of pipe froze caused major operational impediments from Winter Storm Uri’s extreme weather.  

What could happen to Spire Missouri customers without the STL Pipeline?

Spire Missouri relies on the STL Pipeline to transport natural gas into the St. Louis region. Without STL Pipeline, Spire Missouri’s ability to secure new pipeline contracts on other systems serving the region is significantly constrained. This will have a detrimental impact on the health and safety, property and economic prosperity of Missourians.

Without the STL Pipeline, Spire Missouri customers may potentially see serious service disruptions during extreme cold weather periods.

Without the STL Pipeline, Spire Missouri expects customers will begin to lose service at an average daily temperature of 9 degrees Fahrenheit (F) without natural gas supply from STL Pipeline. This temperature threshold increases to 38 degrees F once Spire Missouri’s natural gas storage resource is depleted.

Without the STL Pipeline, there could be widespread impact of gas service outages during the winter which could result in loss of life and property similar to that seen in Texas during Winter Storm Uri in February 2021. 

Without the STL Pipeline during the upcoming winter heating season, approximately 175,000-400,000 Spire Missouri customers may be without gas service, based on Spire Missouri’s previously modeled extreme cold weather planning scenarios. 

If 400,000 customers were to lose service, it may take up to 100 days to reestablish service for all customers in the region.
