HDR Selected as Engineer for Dominion’s Salt Lake City LNG Facility
Dominion Energy Utah has selected HDR to continue as the owner’s engineer for its new liquefied natural gas facility project in Magna, Utah. The selection establishes HDR as the owner’s engineer throughout construction of the facility, continuing the role HDR has held on the project for the past four years.
The Magna LNG facility will provide Dominion Energy Utah customers with a steady, reliable flow of gas to homes and businesses. It is designed to liquefy gas at a rate of 8.2 million standard cubic feet per day (MMscfd) — or 100,000 gallons per day — store it in a 15-million-gallon storage tank and, when needed, vaporize the LNG at a rate of 150 MMscfd.
LNG storage at the facility will enable Dominion Energy Utah to improve supply reliability and save its customers’ costs. Historically, roughly half the natural gas sold to Dominion Energy Utah retail customers comes from company-owned supplies, which are typically more stably priced than gas purchased from other suppliers. When demand is lower in warmer months, “extra” natural gas in liquid form is stored to be available when demand is higher.
HDR’s work on the Magna LNG project includes:
- Assisting with site selection and conceptual design.
- Producing front-end engineering design documents, including a site selection evaluation, preliminary engineering design (site layout, liquefaction and pretreatment technology selection), procurement specifications, contractor engagement, pre-filing of local and state regulatory permits, cost estimates and a project schedule. The FEED was used by the utility as the basis to file a rate case with the State of Utah Public Service Commission.
- Meeting with Salt Lake City planning and zoning boards, local fire marshal and landowners, and developing a public involvement action plan.
- Supporting the project through the Public Service Commission approval process.
Dominion Energy Utah plans to begin construction in 2020 and complete the Magna LNG facility by 2022.Dominion Energy, Dominion Energy Utah, HDR, Magna LNG
