TRGP Targa Resources Corporation

Targa Resources Corp. (NYSE: TRGP) ("Targa" or the "Company") announced today that Targa NGL Pipeline Company LLC (“Targa NGL Pipeline”), a wholly owned subsidiary of the Company, has launched an open season commencing July 1, 2020 and closing July 31, 2020 to gauge shipper interest in committed interstate transportation service for natural gas liquids (“NGLs”) from a planned interconnection with upstream pipeline facilities in Kingfisher County, Oklahoma to Mont Belvieu, Texas. As announced in February 2019, Targa NGL Pipeline is currently developing an approximately 110-mile extension of Targa’s existing Grand Prix pipeline system to the new Kingfisher County interconnection where it will connect with Williams’ new Bluestem Pipeline.

This open season will provide an opportunity for shippers to secure firm capacity for NGL transportation subject to the terms of their transportation service agreements (“TSAs”). The final volume of capacity for both committed and uncommitted service on the project will be determined by Targa in part based on the results of this open season.

It is recommended that interested potential shippers submit signed NDAs on or before 5:00 p.m. Central Standard Time, July 6, 2020, to give those shippers adequate time to evaluate the open season documents.
