Tallgrass Energy Partners (TEP) announced it has increased its revolving credit facility from $850 million to $1.1 billion, and has an option to further increase the revolving credit facility by up to an additional $400 million of commitments to $1.5 billion.

The option may be exercised by TEP within six months of the closing of the facility, which was effective November 24, 2015, and concurrent with or after the acquisition of at least an additional 10% interest in Pony Express. As of September 30, 2015, TEP had $696 million drawn on its revolving credit facility.

According to a related 8-K filing, a syndicate of lenders led by Barclays Bank, as administrative agent, provided the amendment.
