Nuclear Renaissance & Big Tech PPAs
24/7 zero-carbon power demand from AI data centers is triggering a nuclear renaissance. Big tech companies like Microsoft (TMI) and Google (NuScale) are directly signing nuclear PPAs, driving a revaluation of nuclear operators like Constellation Energy and the uranium value chain.
Gas Turbines & On-Site Power Generation
Explosive demand for on-site power generation bypassing 4-5 year grid connection lead times. GE Vernova gas turbine backlog at all-time highs, with a rush of data center-dedicated power plant EPC. Gas turbine lead times are also extending beyond 2 years, deepening the bottleneck.
Grid Infrastructure & Transformers
Data center and renewable energy expansion have made transformers and switchgear a global super-bottleneck. Large transformer lead times exceed 3 years, and Korean power equipment companies are seeing surging North American exports, with 'Korean transformers' emerging as a core part of the global supply chain.
Power Distribution & UPS
Power distribution infrastructure inside data centers. UPS (Uninterruptible Power Supply), PDU (Power Distribution Unit), and busway are essential in high-density rack environments. Vertiv and Eaton dominate the global market, with order backlogs at all-time highs.
Data Center Cooling Revolution
Surging heat output from AI servers has reached the limits of traditional air cooling. Direct Liquid Cooling (DLC) and Immersion Cooling are emerging as new standards, driving rapid growth in the cooling infrastructure market.
Renewable Energy PPAs & Green Data Centers
Big tech RE100 commitments and ESG pressure are driving surging renewable energy PPA demand. Meta, Google, and Microsoft are expanding long-term solar/wind contracts, benefiting renewable energy generators and the energy storage (ESS) market.

10Doosan Enerbility — Korea's Champion Filling the Gas Turbine Big-3 Gap
Global big-3 (GE Vernova/Siemens Energy/MHI) backlogged 5~7 years; Doosan fills the supply void. Cumulative 12 US hyperscaler turbine wins, 30-year LTSA locks in cash flow. Valuation is stretched (EV/EBITDA ~26x, +5x in 1 year) but 30-year visibility partially justifies the multiple.
Constellation Energy — Top Beneficiary of Big Tech Nuclear PPAs
Microsoft's TMI (Three Mile Island) nuclear PPA positions Constellation as the leader in AI data center power supply. As America's largest nuclear operator, benefits from 24/7 carbon-free power premium.
GE Vernova — Core Beneficiary of the Gas Turbine Demand Explosion
40%+ global gas turbine market share. Data center on-site power demand drives backlog past $50B. Emerging as the essential solution bypassing 4-5 year grid connection lead times.
Hyosung Heavy Industries — Top North America Transformer Export Beneficiary
#1 Korean company in the North America ultra-high voltage transformer market. Korean companies gaining competitive edge amid 3+ year global transformer lead times. Rapid earnings growth from expanding North America 765kV transformer orders.
Vertiv — Data Center Power/Cooling Infrastructure Leader
Global #1 in data center power distribution (UPS/PDU) and cooling solutions. AI server power density surge drives backlog past $7B+. Expanding liquid cooling solution lineup.
nVent — Data Center Enclosures & Cooling Solutions

HD Hyundai Heavy Industries — HiMSEN as Korea's Representative in US DC Power Supply
On 2026.4.22, HD Hyundai secured the AEG 684MW deal (34 units, KRW 627.1B) — Korea's first direct US data center engine supply. HiMSEN is Korea's only proprietary-IP 4-stroke medium-speed engine (35% global share, #1 for over a decade), with technology/price/lead-time validated as directly competitive with Wärtsilä. Dual beneficiary of shipbuilding supercycle + power-engine expansion.
STX Engine — 4-Stroke Medium-Speed Tech Base, DC Second-Tier Beneficiary
Korea's #2 in 4-stroke medium-speed engine capability after HD Hyundai. Revenue mix skews to defense/specialty (civilian 43% / specialty 42% / electronics 15%). DC market entry requires dedicated line investment, hyperscaler reference wins, and line-allocation vs defense backlog. Actual beneficiary status depends on follow-on announcement events.
Hanwha Engine — Mid/Long-Term Transition Tied to Hanwha Power Integration
Formerly HSD Engine. Historically 2-stroke low-speed focused, with plans to add 4-stroke production after 2026 capacity expansion. At the group level, Hanwha consolidated Hanwha Power Systems + US PSM into 'Hanwha Power' in March 2026, attempting a pivot into a full-stack energy-infrastructure solutions provider (gas turbine / compressor / service). DC-theme exposure is a mid/long-term (2–3 year) story tied to this group-level energy transformation.
