KANSAS CITY, Mo. -- January 11, 2010

Inergy, L.P. (NASDAQ:NRGY) announced today that its wholly-owned subsidiary,
Inergy Midstream, LLC (“Inergy”), has executed a definitive agreement to
purchase the Seneca Lake natural gas storage facility located in Schuyler
County, New York, (“Seneca Lake”) and two related pipelines for approximately
$65 million from New York State Electric & Gas Corporation (“NYSEG”).

Seneca Lake is an approximate 2.0 billion cubic feet (Bcf) underground salt
cavern storage facility located on Inergy’s US Salt property outside Watkins
Glen, NY, and has a maximum withdrawal capability of 145 MMcf/day and maximum
injection capability of 75 MMcf/day. Seneca Lake is connected to the Dominion
Transmission System via the 16-inch, 20 mile Seneca West Pipeline and
indirectly to the city gate of Binghamton, NY, via the 12-inch, 37.5 mile
Seneca East Pipeline, which runs within approximately 4 miles of Inergy’s
Stagecoach North Lateral interconnect with the Millennium Pipeline.

“Inergy is extremely pleased to announce this agreement to acquire assets that
are a strategic complement to our natural gas storage and transmission hub
strategy,” said John Sherman, President and CEO of Inergy, L.P. “This
acquisition expands our storage and transportation capacity and provides us
with an important pipeline infrastructure that enhances the connectivity and
flexibility we can offer customers on our system. The acquisition, which meets
our investment criteria on a stand-alone basis, will also significantly
enhance the value of Inergy’s existing assets and is expected to increase our
economic return on future expansion projects in the northeast market.”

Inergy will conduct a live conference call and internet webcast Tuesday,
January 12, 2010, to discuss its business outlook giving effect to the Seneca
Lake transaction as well as the recently announced Liberty Propane, L.P. and
MGS Corporation transactions. The call will begin at 3:15 p.m. CT. The call-in

accessed on Inergy’s Web site, A digital recording of the
call will be available for one week following the call by dialing
1-800-642-1687 and entering the pass code 50395843.

Seneca Lake began commercial operation in 1996 and at close of the acquisition
is expected to be contracted with a weighted average maturity of its firm
storage capacity extending to 2015. The acquisition is subject to customary
closing conditions and regulatory approvals. Inergy anticipates closing the
transaction by mid-2010.
