Inergy Announces Open Season on Stagecoach Expansion.

KANSAS CITY, Mo. -- Inergy, L.P. (Nasdaq:NRGY) announced today that its regulated subsidiary Central New York Oil And Gas Company, LLC ("CNYOG"), a New York limited liability company, will conduct a non-binding Open Season for firm storage services provided from a Phase II expansion project at the Stagecoach natural gas storage facility located approximately 150 miles northwest of New York City in Tioga County, New York. The Open Season will begin on Monday, November 21, 2005 and end Friday, December 16, 2005 at 5:00 p.m. CST.

CNYOG proposes to expand the working gas capacity of the existing Stagecoach natural gas facility by approximately 13 Bcf. CNYOG will be filing for a Certificate of Public Convenience and Necessity from the Federal Energy Regulatory Commission ("FERC") seeking authorization of the Phase II capacity expansion. CNYOG expects the rates for storage services to be "market based" and subject to CNYOG's FERC Gas Tariff. Subject to all necessary regulatory approvals, construction is expected to commence in the 3rd or 4th quarter of 2006 with a proposed commercial in-service date of the fall of 2007.

The existing Stagecoach storage facility consists of approximately 13.6 Bcf of working storage capacity that commenced operations in April of 2002 and has provided reliable and flexible storage services for its customers. The storage facility is ideally and strategically located in close proximity to northeastern markets and is connected to Tennessee Pipeline Company's ("TGPL") 300 Line.

It is anticipated the Phase II expansion will consist of an additional 13 Bcf of working storage capacity which will be available for reservation under long-term storage agreements. The Phase II expansion will also include approximately 12 miles of storage lateral and interconnect facilities, the "Stagecoach North Lateral", for a connection to the proposed Millennium Pipeline. Interested parties will be able to contract for a customized range of storage injection and withdrawal services with receipt and delivery points to either TGPL and/or the Millennium Pipeline.

Because of Stagecoach's strategic location between TGPL and the Millennium systems, CNYOG envisions being able to offer hub services between the two pipelines, and seeks expressions of interest in such services in the response to the Open Season.

This Phase II Open Season is a non-binding solicitation for storage capacity and services associated with the expansion of Stagecoach storage facility with the following anticipated capacities and performance levels:

This news release contains forward-looking statements, which are statements that are not historical in nature such as the expectation that the Phase II expansion will add additional 13 Bcf of working gas capacity and construction estimated to begin in 2006 with commercial operations in the fall of 2007. Forward-looking statements are subject to certain risks, uncertainties and assumptions. Should one or more of these risks or uncertainties materialize, or any underlying assumption proves incorrect, actual results may vary materially from those anticipated, estimated or projected. Among the key factors that could cause actual results to differ materially from those referred to in the forward-looking statements are: weather conditions that vary significantly from historically normal conditions, the demand for high deliverability natural gas storage capacity in the Northeast, the general level of petroleum product demand and the availability of natural gas and the price of natural gas to the consumer compared to the price of alternative and competing fuels, our ability to successfully implement our business plan for the Stagecoach facility, our ability to generate available cash for distribution to unitholders, the outcome of rate decisions levied by the Federal Energy Regulatory Commission, and the costs and effects of legal, regulatory and administrative proceedings against us or which may be brought against us. These and other risks and assumptions are described in Inergy's annual report on Form 10-K and other reports that are available from the United States Securities and Exchange Commission.
