This company hopes there's plenty of green out there in the tall grass. Tallgrass Energy Partners (TEP) provides transportation and storage of natural gas in the Rocky Mountains and Midwest. It also provides natural gas processing and treating at its three facilities in Wyoming. TEP's natural gas transportation systems are located in Colorado, Kansas, Missouri, Nebraska, and Wyoming. TEP also maintains a pipeline from the Colorado and Wyoming border to Beatrice, Nebraska, and it provides water business to customers in Colorado and Texas. TEP was formed in early 2013 to hold the midstream assets of its parent, Tallgrass Development. It became a public company a few months later.
