CMS Energy Announces Regulatory Approval for Expansion of its CMS Trunkline LNG Terminal

DEARBORN, Mich., April 3, 2001 - CMS Energy Corporation (NYSE:CMS) today announced its CMS Trunkline LNG unit has received final approval from the U.S. Federal Energy Regulatory Commission (FERC) to expand the peak send out capacity of its Liquefied Natural Gas (LNG) terminal in Lake Charles, La.

The FERC approval authorizes expansion of the Lake Charles LNG terminal from its current 700 million cubic feet per day send out capacity to a peak send out capacity of 1 billion cubic feet per day (Bcf/d). The CMS Trunkline terminal is currently the largest operating LNG facility in the United States.

"Increasing our daily natural gas send out capability to one billion cubic feet will enable us to have greater efficiency, flexibility and reliability to serve growing customer demand and provide our customers with more options," said Christopher A. Helms, president of the CMS Panhandle Pipe Line Companies.

Modifications to the CMS Trunkline LNG facility will eliminate operational bottlenecks in the regasification process. LNG receipt capability of 90 ships per year and storage capacity of 6.3 billion cubic feet will not be affected. CMS Trunkline LNG expects to begin the modifications immediately and have the 1 Bcf/d peak capacity available by June of this year. The modifications will not impact current terminal operations. The Company is evaluating further expansion to increase daily send out capacity to 1.3 Bcf/d.

In 2000, there were 55 LNG tanker ships unloaded at the CMS Trunkline LNG terminal, and it is anticipated that the level of shipments of LNG there will be higher in 2001. CMS Panhandle Pipe Line Companies, which include CMS Panhandle Eastern Pipe Line Company, CMS Trunkline Gas Company and CMS Trunkline LNG Company, operate about 10,900 miles of mainline natural gas pipeline extending from the Gulf of Mexico to the Midwest and Canada. These pipelines access the major natural gas supply regions of the Louisiana and Texas Gulf Coasts as well as the Midcontinent and Rocky Mountains. The pipelines have a combined peak day delivery capacity of 5.4 billion cubic feet per day, 85 billion cubic feet of underground storage facilities and 6.3 billion cubic feet of above ground liquid storage facilities.

CMS Energy Corporation has annual sales of $9 billion and assets of about $16 billion throughout the U.S. and around the world with businesses in electric and natural gas utility operations; independent power production; natural gas pipelines, gathering, processing and storage; oil and gas exploration and production; and energy marketing, services and trading.
