The Public Service Commission of Wisconsin (PSCW) issued a Certificate of Authority granting We Energies approval to construct a 2 billion-cubic-foot (BCF) liquefied natural gas (LNG) storage tank at the existing Oak Creek site.
This 2 BCF facility will take natural gas from the underground pipeline when demand and cost are lower, cool it until it turns to a liquid, then store up to approximately 25 million gallons in the tank until needed. During winter, when demand is high, the LNG is warmed and returned to its vaporous form. It then can be delivered to customers for heating, cooking and meeting other needs, or to facilities to run generating units.

LNG tank taking shape. Crews welded steel plates on top of a foundation constructed from over 2 tons of rebar and 3,000 cubic yards of concrete. The outer shell, shown here with two of its 15 total rings erected, will stand more than 150 feet tall once complete. Two tower cranes over 200 feet tall assist with the construction.
Crews continue to focus on installing underground utilities throughout the project site. There are more than 25,000 linear feet of underground pipes and duct banks to install, these piping systems will support the facility’s operation by sending and receiving fluids and gases to heat (vaporize) and cool (liquefy) natural gas, and deliver fuel gas and compressed air to equipment and instruments throughout the plant.
