Integrys Energy Group, Inc. : First Compressed Natural Gas Fueling Facility in Wisconsin Dedicated

For Release: 05/04/2012

Green Bay, WI - The rain and snow stayed at bay for several hours on Thursday, April 19, 2012, allowing Integrys Transportation Fuels (ITF), a subsidiary of Integrys Energy Group (NYSE: TEG), Paper Transport and the BP SuperStore in De Pere, Wisconsin to dedicate the first public high-capacity Compressed Natural Gas (CNG) Fuel facility for hundreds of miles.

The audience of more than forty people, consisting of area politicians, existing and potential CNG customers and others learned more about the economics, the system and its operation. Also at the dedication, the De Pere Assistant Fire Chief spoke about the safety of the product and its environmental benefits. Jeff Shefchik, President of Paper Transport told his story about his quest to have some of his fleet convert to CNG engines. He reiterated the economics of the fueling system and that it was the right time for them to get involved in the development of the station. "We can now offer others the opportunity to run their products with CNG fuel" Shefchik said. "The closest station was more than a hundred miles away so having a facility in our back yard will open up new opportunities for fleets."

In reference to acquisitions Integrys has made to accelerate its CNG business plan, Integrys Energy Group Executive Vice President and Chief Strategy Officer Mark Radke said, "Because we already had a clear understanding of natural gas, it wasn't a great leap to bring quality companies like Trillium and Pinnacle into the Integrys family. We were eager to add this new addition to our energy portfolio because we knew we would be involved in an emerging industry that could bring our customers another energy service option that could add to their bottom-line, and is environmentally friendly, safe, and reliable."

Job one for ITF is to educate potential consumers and the general public of the benefits of CNG. As demand for the service grows, more facilities like to the De Pere location will be constructed and soon there will may many fueling centers in the Midwest. ITF is working with other fueling centers and fleet operators to make the CNG product more readily available.

Later, a the ribbon was cut and the tours had ended, a bystander who just filled up his big rig with diesel to the tune of $800.00 was shocked when he found out the price for CNG fuel was $1.99 per gallon, less than half the price for diesel. He was impressed and said he was going to look into CNG. Since March 1, 2012 when the station began offering CNG, more than 46,000 gallons have been sold.
