Our history


The Missouri legislature established Laclede Gas Light Company to light the streets of St. Louis with gas lights, create and sell natural gas and install underground pipelines to deliver natural gas to the residents within the city limits. The company was named after the French explorer Pierre Laclede who founded St. Louis.


Laclede Gas Light stock was listed on the New York Stock Exchange with the ticker LG, making the company the eighth longest continuously listed NYSE stock. This was the first year that ticker services were made available to subscribers.


Laclede Gas Light was included in the original Dow Jones Industrial Average. The twelve listed companies were known as the "Dow Dozen."


The joys of “cooking with gas” were introduced to St. Louis kitchens by Laclede Gas Light. The company also began helping customers finance the growing number of gas appliances available for their homes.


Customers were growing (100,000 by 1953) and so was the demand for natural gas. Because existing pipelines could not keep up with the high demand in the winter, naturally occurring underground areas in St. Louis were put to use as places where natural gas could be safely stored. Now Laclede could purchase large quantities of gas when prices were low to supply customers during cold Missouri winters.


Laclede Energy Resources (LER) was created to market natural gas to both large retail and wholesale customers, first in St. Louis, then later to Iowa, Illinois, Arkansas and Louisiana. LER quickly became a regional force in the gas marketing business.


The Laclede Group was established as a public holding company, paving the way for the company’s growth by providing the flexibility to develop or acquire new businesses. Laclede Gas remained the core regulated utility business.


Spire Natural Gas Fueling Solutions was launched to meet the growing fleet demands for cleaner-burning natural gas vehicles. The first Spire station opened at Lambert-St. Louis International Airport in late 2013.


In the largest acquisition in its history, Laclede Gas acquired Missouri Gas Energy, expanding service to Kansas City, Joplin and St. Joseph, Mo. The combined companies now served 1.1 million natural gas customers.


The Laclede Group purchased Alabama Gas Corporation (Alagasco), the largest natural gas provider in Alabama. This brought the number of customers to 1.56 million and number of employees to more than 3,100 across the company.


The Laclede Group announced a pipeline project to access natural gas from shale formations in the northeast. The 60-mile pipeline will improve reliability and lower costs by diversifying supply sources that support customers in Missouri.


The Laclede Group’s board of directors and shareholders voted to change the company’s name to Spire Inc., a result of a multi-year effort to reimagine the company’s future in light of its growth across geographies and businesses.


Spire purchased EnergySouth, the parent company of Mobile Gas and Willmut Gas. This brought the total number of Spire customers to nearly 1.7 million and expanded the company’s footprint within Alabama and to Mississippi.
