Golden Pass plans power plant of up to 250 MW at LNG project

Golden Pass Products LLC and Golden Pass Pipeline LLC on Oct. 13 filed air emissions data, including data for six planned gas-fired turbines, with the Federal Energy Regulatory Commission related to their liquefied natural gas (LNG) project in Texas.

On July 7, Golden Pass Products and Golden Pass Pipeline filed their respective applications with FERC seeking authorization for the Golden Pass LNG Export Project.

“Golden Pass continues to prosecute the requisite permits necessary for receipt of a final order authorizing the Golden Pass LNG Export Project,” the Oct. 13 filing said. “In this regard, Golden Pass is submitting an update to the Prevention of Significant Deterioration (PSD) Permit Application. The PSD Permit Application was filed with FERC on September 12, 2014.”

This data is also part of the ongoing air permitting process for this project at the Texas Commission on Environmental Quality.

The GPX Terminal and MP1 Compressor Station are to be located in Jefferson County, Texas. The gas-fired turbines are to be used to drive compressors for refrigeration of natural gas to facilitate the natural gas liquefaction process. Six turbines equipped with heat recovery steam generators (HRSGs) will be used at the GPX Terminal, two per liquefaction train. There would be two General Electric Frame 7EA gas turbine drivers per train. The GPX Project will also include one gas-fired auxiliary boiler.

Project contacts related to the air permitting are: Jennifer Monopolis (832) 625 4895, Mark Burley (832) 624-3852 or Robert Tomlinson (713) 860-6348.

The proposed facilities would be contiguous to and integrated with the existing LNG import terminal owned and operated by Golden Pass LNG Terminal LLC in the vicinity of Sabine Pass, Texas. Golden Pass has asked the commission to issue a final order no later than July 1, 2015. Authorization by then is necessary to allow for completion of construction, testing and final commissioning of the project facilities to achieve commercial startup of Train 1 in September 2019, Train 2 by March 2020, and Train 3 by September 2020.

Golden Pass Products proposes to construct and operate three liquefaction trains with a total capacity to produce up to 15.6 million metric tons per of LNG annually, equivalent to 740 Bcf. Golden Pass Products further proposes to modify the existing LNG import terminal facilities to provide for optimization of existing facilities and equipment.

In addition, Golden Pass Products proposes: feed gas treatment facilities, including removal systems for mercury, carbon dioxide, hydrogen sulfide and heavy hydrocarbons; and a 200 MW-250 MW self-generation power plant.

Said one permit document about the power plant: “Power will be generated utilizing [high pressure] steam to drive [steam turbine generators]. Three (3) STGs will be located, one (1) in each train, and use HP steam by expanding it to very low pressure steam to generate electric power. The exhaust from the STG will be condensed via a surface condenser and the condensate pumped to a recovered condensate tank. The power generation capacity of each STG is expected to be about 100 MW. The liquefaction facility internal power grid will be connected to the utility power grid (Entergy) for back‐up power demand in case of a trip of an individual STG as well as for startup power demand.”

Golden Pass Pipeline wants to construct and operate compression and looping facilities on its existing interstate pipeline in Texas and Louisiana, and to modify certain existing interconnection facilities to provide for bi-directional service related to the LNG project.

The Golden Pass Export Project represents a $10bn capital investment. Golden Pass Products is owned by QTL U.S. Terminal LLC, an affiliate of Qatar Petroleum International Limited, and Golden Pass LNG Terminal Investments LLC, an affiliate of Exxon Mobil Corp.
