Korea puts $23.2 billion into a Texas gas plant still at the development stage
The government told the National Assembly that the Encinal combined-cycle project in Texas should return $43bn to $45bn over 20 years. People Power Party lawmakers left the closed-door briefing asking who buys the power.

What happened
- Two National Assembly committees took a closed-door government briefing on the 22nd on US investment under the special act governing Korea-US strategic investment.
- The government said it plans to invest $23.2 billion in the Encinal gas-fired combined-cycle project in Texas, the first project selected under the US investment program.
- Koo Ja-keun said the government put recovery at $43 billion to $45 billion over 20 years and judged that the project has commercial merit.
- Lawmakers asked for further verification, saying it is unclear whether long-term buyers for the electricity have been secured.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- constraint One project takes 116 percent of the $20 billion a year Korea agreed not to exceed, so the reactors and Alaska LNG behind it are bidding for room in later years of the same envelope.
- exposure Korean public money sits on development-stage risk at a return that turns on the payment schedule: $2.25 billion a year for 20 years is near 7.4 percent, the same $45 billion paid once at year 20 is 3.4 percent.
- contradiction One briefing produced two readings of the same number, with the government saying commercial merit is secured and the industry committee chairman saying the grounds, power buyers included, still need examining.
- precedent Pricing a Westinghouse stake against how much reactor construction Korean firms get sets the pattern for the second project being negotiated as equity and workshare together.
Divide the $45 billion by 20 years and the return is $2.25 billion a year against $23.2 billion paid up front, an internal rate near 7.4 percent with payback around year ten [16][23]. Assume instead that the whole $45 billion arrives once, at the end of year 20, and the same two numbers compound at 3.4 percent [17]. Take Koo Ja-keun's low end of $43 billion and they become roughly 6.8 percent and 3.1 percent [18]. The government gave the committees one sentence and no payment profile, so both readings fit it [24].
Gross gain over the two decades is $21.8 billion [21]. The range the government offered is $2 billion wide, about 4.5 percent of its own midpoint [22]. Koo said the project is early. "Since it is still at the development stage, there are concerns about whether other variables could emerge in the process, so we said caution is needed," he told reporters [4]. In my view a band that tight comes out of a model with contracted revenue in it, and the contracts are the part lawmakers say they have not been shown [6].
Bae Joon-hyung of the People Power Party is the opposition liaison on the finance and economy committee. He said: "Someone has to buy the electricity, so we pressed on who will buy it, who will build the data centers and whether they have sufficient capacity, and whether they have experience building data centers before." [7][15] He added, "We raised the issue that these points are not clear." [8]
The government also reaffirmed that no additional investment will be made beyond $20 billion a year and $200 billion in total [13]. Encinal therefore takes 11.6 percent of the lifetime ceiling and 116 percent of a single year's [20][19]. Behind it sit eight large reactors in the United States as the second project and Alaska LNG development as the third. Both are to be pursued reflecting the interests of both countries, with feasibility reviewed after further consultation with the US side [10].
The trade ministry reported it is discussing a stake in Westinghouse of between 5 and 10 percent, tied to how Korean companies take part in reactor construction in the United States, according to sources cited by Seoul Economic Daily [11][12]. That structure puts equity and workshare in the same negotiation.
The $23.2 billion is what Korea pays; the $45 billion is a projection, and it depends on an offtake contract [6]. The counter-thesis is serious. The government reported that it judged the project has commercial merit [3], and it may be holding an operator's contracted model it will not publish while terms with Washington are unsettled, in which case what is late is the disclosure. A named buyer and a payment schedule would settle which number is real. The memorandum with Washington has no date, and Kim Sung-won said, "No date has come out yet." [14] Meanwhile $23.2 billion of gas in Texas is $23.2 billion not spent on the reactors or on Alaska under a ceiling the government says it will not breach [13].
What to watch
- Publication of power purchase agreements or named offtakers for Encinal, with contract terms and a payment schedule.
- The date of the Seoul-Washington memorandum, and whether the $20 billion a year and $200 billion ceiling language survives it intact.
- Where the Westinghouse stake settles between 5 and 10 percent, and what share of US reactor construction comes with it.
