The Waha Storage Hub is strategically located near a major trading hub with excellent pipeline access. Waha will allow customers flexibility to handle daily, monthly and seasonal peaking requirements; pipeline balancing needs; and operational load requirements.

Formerly called the Chaparral Energy Center, the site was acquired as part of ENSTOR's acquisition of assets from Aquila in December 2002 that included the Katy gas storage facility near Houston. The Waha project is expected to be developed in two phases over the next three years, with the first phase operational in late Spring 2009.
