Northern Natural's 210,000-Dth/d proposal passes FERC environmental review

FERC Office of Energy Projects staff signed off on a proposalto build facilities to increase natural gas transportation capacity to a Texas powerprovider by 210,000 Dth/d.

"We recommend that the commission order contain a findingof no significant impact," staff said in the May 9 environmental assessment.FERC staff added that certain mitigating measures should be recommended as conditionsin any approval from the commission to Northern.

The project is expected to cost approximately $40.6 million.

On Sept. 9, 2015, Northern submitted an abbreviated application for the project, which would includeconstruction of and operation of a new compressor station and associated facilitiesin Gaines County, Texas. The new compressor station would deliver an additional210,000 Dth/d of firm incremental transportation services to Northern's existingcustomer Golden Spread Electric CooperativeInc. The cooperative has fully subscribed to the additional capacity.

The greenfield compressor station would run the additional naturalgas through two existing pipelines, 815B on the discharge side and 840B on the suctionside. The project would involve the installation of one gas-fired turbine compressorunit with about 11,152 horsepower; one gas-fired turbine compressor unit with about6,937 hp; and two compressor buildings, a new backup generator and associated above-gradeand below-grade piping.

Northern planned to place the project into service by May 1,2017, earlier than an original in-service deadline of June 1, 2017, under the assumptionthat FERC will authorize the compressor station project by Sept. 1, 2016. Northernwould like to begin construction activities in November. Construction is estimatedto take approximately seven months.

Northern is a BerkshireHathaway Energy company. (CP15-552)
