Analysis

All Four Makers Post Jan-May Revenue Growth: AI Pull Drives Heavy Electrical Equipment Demand

Taiwan's four major heavy electrical equipment makers reported strong Jan-May 2026 revenue, with all four posting growth relative to the prior year (AINews #884576). [F1][F5][F9][F13]

**Allis Electric (1514)**: Per Taiwan Stock Exchange disclosure, May 2026 monthly revenue was approximately NT$800 million (YoY -30.83%) (TWSE #941757). [F1a] Jan-May cumulative revenue reached NT$4.198 billion, YoY +10.77% (AINews #884576). [F1] As of May 2026, Allis Electric's order backlog exceeded NT$12 billion, continuously hitting new highs, primarily driven by the AI wave accelerating heavy electrical equipment demand (AINews #884576). [F2] Order intake in 2026 has already exceeded sales by 30%, with semiconductor industry chain revenue contribution doubling YoY (AINews #884576). [F4]

Allis Electric also secured overseas orders from an NVIDIA-invested subsidiary in Central/South America — the only one among the four to publicly disclose direct orders from an international AI chip giant (AINews #884576). [F3]

**Fortune Electric (1519)**: May 2026 monthly revenue was approximately NT$1.477 billion (YoY -9.33%, second-highest for the period), with Jan-May cumulative revenue reaching NT$8.482 billion, YoY +3.9% (AINews #884576). [F5] (Note: Fortune Electric's monthly revenue filings were not found in the TWSE database; this data is sourced from CNA's composite reporting.)

At the June 12, 2026 shareholders' meeting, Fortune Electric General Manager Hsu Yi-Te disclosed a more striking figure: **AIDC (AI Data Center) power transformer order backlog has reached NT$20 billion** (AINews #952495). [F6] Fortune Electric estimates 2026 AIDC shipment value at NT$4–5 billion, with AIDC revenue share exceeding 15% (AINews #952495). [F7] Overall order visibility extends to 2029, with average product delivery lead times reaching 2.5–3 years, indicating demand far outpacing supply (AINews #952495). [F8]

Fortune Electric's Jan-Apr 2026 export ratio rose to 66%, with a full-year export target above 60%, as US cloud service providers (CSPs), fearing underinvestment, are making large-scale capital expenditures to strengthen power infrastructure (AINews #952495). [F8] Fortune Electric is also bidding to supply transformers for the AIDC project in Kagoshima, Kyushu, Japan — a situation that may become clearer in H2 2026 (AINews #952495).

**Shihlin Electric (1503)**: May 2026 monthly revenue was NT$3.049 billion (YoY +8.35%), with Jan-May cumulative revenue reaching NT$18.012 billion, YoY +14.89% — the largest revenue scale among the four (AINews #884576). [F9]

Shihlin Electric currently has the longest order visibility among heavy electrical equipment makers — **extending to 2029 or even 2030** — and continues expanding heavy electrical equipment capacity in both Taiwan and North American markets (AINews #884576). [F10] From 2026 onward, North American market annual growth is targeted at 15–20% (AINews #884576). [F12] The Economic Daily News reported on June 18 that Shihlin Electric's order backlog had reached NT$60 billion (a media figure referenced in the company's TWSE clarification #1124545). [F16]

At the June 17 shareholders' meeting, Shihlin Electric approved a cash dividend of NT$5 per share and clearly outlined its international transformation roadmap: accelerating international certification for high-voltage, high-capacity equipment in Europe and the US, targeting transformation into a global heavy electrical supplier (AINews #1059505). [F11] Shihlin Electric noted that AI and high-performance computing are powerfully driving heavy electrical industry momentum, with Taiwan Power Company's grid resilience plan at peak execution and international tech giants plus Taiwanese manufacturers aggressively expanding data centers, creating enormous power infrastructure demand (AINews #1059505).

**Chung-Hsin Electric (1513)**: May 2026 monthly revenue was NT$2.392 billion (YoY +3.62%), with Jan-May cumulative revenue reaching NT$11.19 billion, YoY +2.33% (AINews #884576). [F13] Chung-Hsin Electric targets double-digit operational growth in 2026, with its high-voltage gas-insulated switchgear (GIS) equipment having obtained certification from a major semiconductor wafer manufacturer, with shipments to new domestic fab zones expected from Q4 2026 (AINews #884576). [F14] In AI data center applications, Chung-Hsin Electric has entered engineering, procurement, and construction (EPC) projects in 2026. Media reports indicate Chung-Hsin Electric's order backlog stands at approximately NT$40 billion, with some order visibility extending to 2031 (a media figure referenced in the company's TWSE clarification #517077). [F17]

AI Infrastructure's Dual-Engine Effect: Semiconductors + Power

The revenue growth and order expansion of these four companies are not isolated events. Their growth momentum is tightly coupled with TSMC's 2026 simultaneous 3nm global expansion revealed in Batch 1 (ANK-2026-04-16-001).

TSMC is simultaneously expanding 3nm capacity across three countries — Taiwan, the US, and Japan — in 2026 (ANK-2026-04-16-001 F-010). Every new wafer fab construction, along with the accompanying AI data center buildout, requires massive quantities of transformers, switchgear, and distribution panels — precisely the core products of Allis Electric, Fortune Electric, Shihlin Electric, and Chung-Hsin Electric.

The four companies' order visibility extending from 2029 to 2031 closely aligns with TSMC's and global semiconductor manufacturers' expansion timelines (Southern Taiwan Science Park 3nm: H1 2027, Arizona Fab2: H2 2027, Kumamoto Fab2: 2028, A14 process: 2028 volume production). This indicates that AI infrastructure is forming a complete dual track: **wafer fabrication (TSMC) → advanced packaging (CoWoS/CoPoS) → power infrastructure (heavy electrical Big Four)**.

Market Landscape: From Taipower Suppliers to Global AI Supply Chain

The four heavy electrical equipment makers are undergoing a fundamental strategic repositioning:

| Company | Ticker | Traditional Role | AI Transformation | Key Signal | |---------|:------:|------------------|-------------------|-----------| | **Allis Electric** | 1514 | Taipower grid resilience supplier | AI server room construction + semiconductor fab power distribution | NVIDIA C/SA order · TWSE monthly filings | | **Fortune Electric** | 1519 | Domestic transformer manufacturing | AIDC transformer global supplier (NT$20B backlog) | Jan-Apr exports 66% · Bidding for Kagoshima, Japan | | **Shihlin Electric** | 1503 | Domestic heavy electrical EPC | Global heavy electrical supplier (EU/US/ME/SEA) | Accelerating EU/US certification · Media reports NT$60B backlog · NT$5 dividend | | **Chung-Hsin Electric** | 1513 | GIS equipment manufacturer | Semiconductor certification + AI data center EPC | GIS certified by major semiconductor maker · Media reports NT$40B backlog |

Fortune Electric's transformation is the most pronounced in 2026: AIDC transformer order backlog of NT$20 billion as of June 12, with full-year AIDC revenue share expected to exceed 15%, and export ratio surging from below 50% historically to 66% in Jan-Apr 2026. Its Taichung plant expansion, with an investment of approximately NT$2.5 billion, is expected to begin production in Q3 2027, doubling capacity and capable of producing 500kV-class transformers — making it Southeast Asia's largest power transformer production base (AINews #952495).

FAQ

Q: Why is Taiwan's heavy electrical industry benefiting from AI?

AI data centers require enormous amounts of power — a single data center can consume as much electricity as a small city. This drives massive demand for transformers, high-voltage switchgear, and distribution panels. Fortune Electric's AIDC transformer order backlog exceeds NT$20 billion, and Shihlin Electric's order visibility reaches 2030 — indicating this is not a short-term surge but a structural demand cycle lasting 7–10 years (AINews #884576, #952495).

Q: Which of the four companies benefits the most?

By direct AI data center relevance: Fortune Electric has the largest AIDC order scale (NT$20 billion) and highest export ratio (66%). Shihlin Electric has the largest revenue scale (NT$18.012B) and longest visibility (2030), with media reports of NT$60 billion in backlog. Allis Electric secured direct NVIDIA orders. Chung-Hsin Electric's GIS earned semiconductor major certification. Each has distinct competitive advantages (AINews #884576, #952495, #1059505, TWSE #1124545, #517077).

Q: What does Fortune Electric's NT$20 billion AIDC backlog represent?

Fortune Electric's Jan-May 2026 revenue was NT$8.482 billion, with full-year estimated at roughly NT$20 billion. A NT$20 billion order backlog means approximately an entire year's revenue comes from AI data centers alone. Moreover, Fortune Electric's 2026 AIDC shipment value is estimated at only NT$4–5 billion, leaving NT$15–16 billion for delivery in subsequent years — providing clear multi-year revenue visibility (AINews #952495).

Q: What is the relationship between heavy electrical equipment and TSMC?

Every new TSMC wafer fab is a massive customer for heavy electrical equipment — requiring dedicated transformers, high-voltage distribution systems, and uninterruptible power supplies. TSMC's simultaneous 3nm expansion across Southern Taiwan Science Park, Arizona, and Kumamoto in 2026 (ANK-2026-04-16-001) generates orders for heavy electrical equipment makers with each new fab. Allis Electric explicitly noted that semiconductor industry chain revenue contribution doubled in Jan-May 2026, confirming the tight dual-track growth linkage (AINews #884576).

Q: How long can this trend continue?

Based on order visibility from three companies: Fortune Electric sees to 2029, Shihlin Electric to 2030, and media reports indicate Chung-Hsin Electric's visibility extends to 2031. Fortune Electric's delivery lead times have already reached 2.5–3 years, meaning current orders won't be delivered until 2029 at the earliest. With the world in the midst of an AI data center construction boom, ongoing grid resilience investments, and the global energy transition, the heavy electrical industry growth cycle is expected to last at least through 2030 (AINews #884576, #952495, #1059505).

Q: What are the investment risks for these heavy electrical companies?

Key risks include: (1) extreme supply-demand imbalance may cause capacity shortfalls (Fortune Electric lead times already at 3 years as of June 2026), potentially missing order windows; (2) rising 2026 export ratios increase currency and tariff risks; (3) copper, steel, and insulation material cost volatility impacts margins; (4) labor shortages constrain production capacity expansion. Fortune Electric has begun avoiding large turnkey projects and concentrating resources on high-margin products as a mitigation strategy (AINews #952495).

❓ FAQ

Why is Taiwan's heavy electrical industry benefiting from AI?

AI data centers require enormous amounts of power — a single data center can consume as much electricity as a small city. This drives massive demand for transformers, high-voltage switchgear, and distribution panels. Fortune Electric's AIDC transformer order backlog exceeds NT$20 billion, and Shihlin Electric's order visibility reaches 2030 — indicating this is not a short-term surge but a structural demand cycle lasting 7–10 years (AINews #884576, #952495).

Which of the four companies benefits the most?

By direct AI data center relevance: Fortune Electric has the largest AIDC order scale (NT$20 billion) and highest export ratio (66%). Shihlin Electric has the largest revenue scale (NT$18.012B) and longest visibility (2030), with media reports of NT$60 billion in backlog. Allis Electric secured direct NVIDIA orders. Chung-Hsin Electric's GIS earned semiconductor major certification. Each has distinct competitive advantages (AINews #884576, #952495, #1059505, TWSE #1124545, #517077).

What does Fortune Electric's NT$20 billion AIDC backlog represent?

Fortune Electric's Jan-May 2026 revenue was NT$8.482 billion, with full-year estimated at roughly NT$20 billion. A NT$20 billion order backlog means approximately an entire year's revenue comes from AI data centers alone. Moreover, Fortune Electric's 2026 AIDC shipment value is estimated at only NT$4–5 billion, leaving NT$15–16 billion for delivery in subsequent years — providing clear multi-year revenue visibility (AINews #952495).

What is the relationship between heavy electrical equipment and TSMC?

Every new TSMC wafer fab is a massive customer for heavy electrical equipment — requiring dedicated transformers, high-voltage distribution systems, and uninterruptible power supplies. TSMC's simultaneous 3nm expansion across Southern Taiwan Science Park, Arizona, and Kumamoto in 2026 (ANK-2026-04-16-001) generates orders for heavy electrical equipment makers with each new fab. Allis Electric explicitly noted that semiconductor industry chain revenue contribution doubled in Jan-May 2026, confirming the tight dual-track growth linkage (AINews #884576).

How long can this trend continue?

Based on order visibility from three companies: Fortune Electric sees to 2029, Shihlin Electric to 2030, and media reports indicate Chung-Hsin Electric's visibility extends to 2031. Fortune Electric's delivery lead times have already reached 2.5–3 years, meaning current orders won't be delivered until 2029 at the earliest. With the world in the midst of an AI data center construction boom, ongoing grid resilience investments, and the global energy transition, the heavy electrical industry growth cycle is expected to last at least through 2030 (AINews #884576, #952495, #1059505).

What are the investment risks for these heavy electrical companies?

Key risks include: (1) extreme supply-demand imbalance may cause capacity shortfalls (Fortune Electric lead times already at 3 years as of June 2026), potentially missing order windows; (2) rising 2026 export ratios increase currency and tariff risks; (3) copper, steel, and insulation material cost volatility impacts margins; (4) labor shortages constrain production capacity expansion. Fortune Electric has begun avoiding large turnkey projects and concentrating resources on high-margin products as a mitigation strategy (AINews #952495). ---

🧠 編輯判斷(J-Units)

Taiwan's heavy electrical industry is undergoing an "AI-driven structural demand shift" — the phenomenon of all four companies posting revenue growth relative to the prior year, with order visibility extending to 2029–2031, indicates that AI data center and semiconductor fab expansion-driven heavy electrical equipment demand is not a short-term pull but a 7–10-year infrastructure investment cycle
Confidence: medium · Based on: F-002, F-006, F-010, F-012, F-015
The customer structure of heavy electrical equipment makers is shifting from "Taipower-centric domestic power utilities" to "global AI supply chain" — export ratios surging from below 50% historically to Fortune Electric's 66%, while Shihlin Electric accelerates EU/US certification for global expansion, signaling an upgrade in Taiwan's heavy electrical industry positioning within the international division of labor
Confidence: medium · Based on: F-008, F-012, F-003
Fortune Electric's AIDC transformer NT$20 billion order backlog (roughly equivalent to annual revenue) and 2.5–3-year delivery lead times signal that the AI transformer market has graduated from "emerging opportunity" to "core business" — the severity of the supply-demand imbalance indicates demand growth far outpacing capacity expansion, a characteristic feature of early-stage technology cycle supply crunches
Confidence: medium · Based on: F-006, F-007, F-005
AI infrastructure is forming a complete dual-track effect — Batch 1's TSMC (chip manufacturing) and Batch 2's heavy electrical Big Four (power infrastructure) are different layers of the same AI demand wave. Each TSMC new fab is a massive customer for heavy electrical equipment, and their capital expenditure cycles are tightly coupled, forming a complete AI infrastructure investment chain from wafer to power
