Caledonia Energy Partners Announces Storage Capacity Open Season; Tenaska to Provide Marketing Services - 04/20/06

DALLAS, Texas – Caledonia Energy Partners, L.L.C. (CEP) has announced an open season for 1.7 billion cubic feet (Bcf) of available working natural gas storage capacity at the Caledonia gas storage facility, under development near Caledonia, Mississippi.

CEP is converting a depleted natural gas reservoir into a high-deliverability, multi-cycle natural gas storage facility capable of storing 11.7 Bcf of working gas. The facility is expected to go into service in the spring of 2007. Tenaska Power Fund, L.P., a private equity limited partnership, has a 50 percent ownership interest in CEP.

Caledonia has entered into an exclusive agreement with Tenaska Caledonia, LLC, a subsidiary of Tenaska, Inc. to provide marketing support for the facility. Tenaska Caledonia will administer an open season for the 1.7 Bcf of capacity which is not yet under contract, as well as manage the nominations, scheduling and balancing of the storage contracts and marketing of interruptible services. The open season will begin April 20, 2006 and end May 5, 2006 at 5:00 p.m. CST. Details are available at www.caledoniastorage.com.

The storage facility will be strategically interconnected with Tennessee Gas Pipeline, 500 Leg, Zone 1 in Lowndes and Monroe Counties, Mississippi. The pipeline serves the growing natural gas demand markets in the Northeast, Southeast and Ohio Valley regions of the U. S. The current plans provide for the Caledonia storage facility to deliver a maximum of 330,000 thousand cubic feet (Mcf) per day and up to four cycles per year.

“The strategically located Caledonia storage project is in an area traversed by numerous interstate pipelines and provides excellent access to multiple electric power and natural gas markets,” said CEP President Jim Goetz.

Parties interested in more information about the project should contact Karen Swett (402) 938-1632, kswett@tenaska.com.
