Consultants warn phased approach, permitting and cost risks could imperil Alaska LNG megaproject

Summary
Pegasus Global and Texas Global told the Senate Resources Committee that megaprojects and —giga— programs carry elevated risks: historical case studies (Mountain Valley and Atlantic Coast pipelines) showed large cost growth, permits and litigation can stop projects, and a phased pipeline approach can lower initial capital but raise structural and schedule risk for export economics.
Pegasus Global and Texas Global presented to the Alaska Senate Resources Committee on April 16, warning that large pipeline and LNG projects face significant execution, permitting and financing risks and that phasing the Alaska LNG program introduces trade‑offs.
Joe Miller of Pegasus and Jeremy Clark of Texas Global summarized U.S. case studies in which permit challenges and construction litigation materially altered outcomes. Miller cited the Mountain Valley pipeline, which his presentation showed rose from an initial estimate near $3.5 billion to roughly $9.6 billion at completion, and the Atlantic Coast pipeline (initially estimated near $4.5 billion and later above $8 billion) that was canceled. Miller said permitting cycles, construction‑practice challenges, and litigation were central contributors to those cost and schedule outcomes.
Clark described megaprojects (> $1 billion) and gigaprojects (transformational programs) and said the Alaska LNG program is best treated as a giga program with three threshold components — pipeline, treatment plant and terminal — each of which could approach mega scale. "From our perspective, we would treat the overall program as a giga program," Clark said.
On the committee's question whether phasing (building the pipeline first, then treatment and terminal) reduces risk overall, Clark and Miller described the trade‑offs: phased execution can lower upfront capital and deliver in‑state gas sooner (AGDC previously estimated first gas 2–3 years earlier under a phased plan), but it ties pipeline economics to later LNG export revenue and can create multiple waves of labor, camps and community impacts. Miller said a key finance question is whether phase 1 can be financed as a standalone project; that depends on contracted volumes and contract firmness. "One question we have is, is phase 1 financeable on a standalone basis?" Miller said; he noted that phase‑1 costs and assumed off‑taker volumes materially affect that analysis.
The consultants also discussed gas‑supply options for Southcentral Alaska. Clark flagged declining Cook Inlet production as a supply risk, the phase‑1 pipeline as a high capital and schedule risk, and LNG imports as a lower‑capex but higher market‑price exposure alternative. Committee members and presenters noted that pursuing both imports and the export program is possible and could provide short‑term relief while preserving equipment reuse for eventual exports.
Asked about consumer protection from potential cost overruns, Joe Miller said commitments that overruns not be passed to customers should be memorialized — either in contracts between the project and local utilities, in RCA filings, or in legislation — to reduce consumer risk and improve bankability. "That needs to be memorialized in some fashion," he said.
The presenters urged rigorous independent cost estimates (class 2 estimates and associated risk modeling), strong stakeholder alignment, and contracting strategies that share risk and incentives across owners, contractors and off‑takers. The committee took the presentation under advisement and continued follow‑up questioning on financing assumptions and permit durability.
