Centragas operates a pipeline in the areas of La Guajira, Cesar and Santander in Colombia. Centragas has a capacity of 200 mmcfd.
Centragas operates under a build, operate, maintain and transfer (BOMT) agreement with Ecopetrol which expires in February 2011. At the end of the term, ownership of the pipeline reverts to Transportadora de Gas del Interior, or TGI, an entity recently privatized by the Colombian government. Under its BOMT agreement, Centragas is paid by a tariff, independent of volumes transported. Centragas' tariff is set by the terms of its BOMT agreement and is not regulated by the Colombian Regulatory Commission for Energy and Gas.
Promigas operates the Centragas pipeline under a long-term operations and maintenance contract with Centragas. The term of the contract is through the transfer of the pipeline to TGI in February 2011.
