Powder River Gateway Tallgrass Energy formed a joint venture with Silver Creek Midstream in 2018 – the Powder River Gateway, LLC – which owns the Iron Horse Pipeline, the Powder River Express Pipeline (PRE) and crude oil terminal facilities in Guernsey, Wyo. Both Iron Horse and PRE transport crude oil produced in the Powder River Basin from Silver Creek’s Pronghorn Terminal to Guernsey, where the crude oil has access to Tallgrass' Pony Express crude pipeline system and two other takeaway pipelines. Tallgrass operates the Powder River Gateway joint venture and owns 51 percent; Silver Creek owns 49 percent.

Iron Horse Pipeline is an approximately 80-mile, 16-inch crude oil pipeline with a design capacity of approximately 100,000 barrels per day and expansion potential. Powder River Express is an approximately 70-mile, 12-inch crude oil pipeline with capacity of 90,000 barrels per day and expansion capability. The joint venture’s crude oil terminal facilities in Guernsey collectively own over 340 acres and include more than 1 million barrels of storage.
