A Reliable Supply of Natural Gas for the Salt Lake City Area

For four years and counting, we’ve acted as owner’s engineer for Dominion Energy Utah on its Magna liquefied natural gas facility project. The new facility is designed to provide customers with a steady, reliable flow of gas to homes and businesses. It will liquefy gas at a rate of 8.2 MMscfd (378,000 litres per day), store it in a 56-million-litre storage tank and, when needed, vaporise the LNG at a rate of 150 MMscfd.

Historically, about half the natural gas sold to Dominion Energy Utah’s 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 so it’s available when demand is higher.

Our work on the 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.

We’ll continue serving as owner’s engineer through construction. Dominion Energy Utah plans to have the facility up and running by the end of 2022.
