Interior Gas Utility outlines construction plans, grants and North Slope LNG timeline

At a meeting of the Fairbanks North Star Borough Assembly Committee of the Whole, Elena Suddath, general manager of Interior Gas Utility, gave a quarterly update that outlined upcoming construction plans, grant-funded mainline work in North Pole and a revised timeline for commercial LNG from the North Slope.

Suddath said IGU has about 100 new service agreements to date and plans to continue installing new main lines this construction season. "We have about 100 new service agreements to date," she said. She told the assembly the utility plans to use roughly $2,500,000 in targeted airshed grants to extend mainline in the North Pole area to encourage additional household conversions in the borough’s worst air-quality zone. She also said about $1.5 million remains from last year’s state grant for small mainline extensions to customers who are ready to install service lines and convert to natural gas.

The utility also expects to purchase emergency-response equipment with a grant from the federal pipeline regulator that was paused and later released. Suddath identified the federal agency as the Pipeline and Hazardous Materials Safety Administration (PHMSA) and said IGU will use that funding to buy locators and other emergency-response gear.

IGU staff described community outreach planned for the season: two recent open houses and town-hall events (one in Fairbanks and one in North Pole), participation in a local home show and additional outreach planned at a Fairbanks home-show event. Suddath said the open houses bring together the borough’s air-quality division, mechanical contractors and suppliers so residents can confirm gas availability, complete IGU applications and request contractor quotes. "We always recommend that people get multiple quotes," she said.

On regional infrastructure, Suddath said IGU has supported legislative efforts to integrate a lateral from an Alaska LNG project into the Fairbanks North Star Borough distribution system, and that IGU submitted letters of support and coordinated testimony with local leaders. She reported that the North Slope liquefaction pad she recently visited is taking shape and that Harvest had given IGU a revised schedule putting first LNG deliveries "sometime in July." She described the facility’s cold box and on-pad storage and said local storage at the new pad is planned for roughly one day of full-capacity output (or about two days at the facility’s initial, half-capacity operating level). She also noted IGU’s existing Titan liquefaction operation currently loads LNG directly into trailers.

Technical details mentioned during the exchange included LNG temperature and storage construction: a meeting participant asked about LNG temperature; Suddath replied "265 degrees" (referring to about -265°F typical LNG temperature), and she explained double-shell storage design using perlite insulation and the routine presence of boil-off gas. IGU said Storage Site 3 includes three boil-off compressors to manage pressure and recompress gas in low-demand periods; in winter any boil-off is likely routed into the distribution system. Suddath also reminded contractors and residents to call 811 before digging so utilities can be marked (she said the state service typically responds within about 48 hours).

Assembly members asked technical and policy questions about adding capacity via additional LNG "trains," opportunities to coordinate conduit/fiber placement when digging for gas mains, and the bill-tracking status of the state legislation referenced in IGU’s testimony. On capacity, Suddath said the Harvest contract allows construction of up to two additional trains of the same capacity, if needed. On coordination with telecoms, IGU said it sometimes coordinates with municipalities and DOT to lay pipe when streets are open and offered to follow up to explore fiber conduit opportunities.

No formal borough action was taken during the report; the briefing closed after questions and moved on to the next agenda items.

Ending: IGU’s update flagged near-term construction, grant-supported mainline work in North Pole, purchases of safety equipment using a federal grant, and a revised July timeline from Harvest for first LNG at the North Slope facility. Assembly members asked for follow-up on telecom coordination and legislative developments.
