Taiwan’s proposed energy law could raise power costs for TSMC and other major industries
Taiwan is preparing a major change to its energy rules that could significantly affect some of the country’s biggest electricity users, including Taiwan Semiconductor Manufacturing Company, better known as TSMC.
The Ministry of Economic Affairs is pushing an amendment to the Energy Management Law that would require large commercial electricity consumers to build their own power generation and energy storage systems. Lawmakers are expected to review the proposal on July 22.
If approved, the new rule would mark a major shift in how Taiwan manages industrial power demand, especially as semiconductor manufacturing and AI data centers continue to consume growing amounts of electricity.
Under Taiwan’s existing renewable energy rules, large commercial power users are already required to offset 10 percent of their electricity consumption with renewable energy. The proposed amendment goes further by requiring these companies to install dedicated power generation and storage infrastructure of their own.
The rule would apply to commercial entities with electricity demand of 5 megawatts or more. That threshold would bring more than 400 facilities under the regulation, including semiconductor plants, optoelectronics factories, steelmakers, petrochemical sites, and AI data centers.
TSMC is expected to be one of the companies most affected by the proposal. As Taiwan’s largest electricity consumer, the chipmaking giant relies heavily on grid-supplied power to run its extensive network of fabrication plants. If TSMC is required to support more of its own electricity needs through captive power generation and storage systems, its operating costs could rise meaningfully.
The company currently operates a large manufacturing footprint in Taiwan, including six 12-inch GIGAFAB facilities: Fab 12, Fab 14, Fab 15, Fab 18, Fab 20, and Fab 22. It also runs four 8-inch wafer fabs, including Fab 3, Fab 5, Fab 6, and Fab 8, along with one 6-inch wafer facility known as Fab 2. In addition, TSMC operates multiple advanced packaging plants, which are increasingly important as demand grows for high-performance chips used in artificial intelligence, smartphones, servers, and other advanced electronics.
The scale of TSMC’s electricity use is enormous. In 2024, the company consumed around 25.55 billion kilowatt-hours of electricity in Taiwan. That represented roughly 9 percent of the country’s total electricity consumption. Replacing or supplementing that level of grid power with self-owned generation and storage infrastructure would be a massive challenge.
For Taiwan, the proposed law reflects a growing concern over power stability, energy security, and rising industrial electricity demand. The semiconductor industry is the backbone of the country’s economy, but chip fabrication is extremely energy-intensive. Advanced manufacturing nodes require constant, reliable electricity for cleanrooms, lithography machines, cooling systems, and other precision equipment.
AI data centers are also adding pressure to Taiwan’s power grid. As artificial intelligence workloads expand, demand for high-density computing infrastructure is rising quickly. These facilities require large amounts of electricity not only to run servers, but also to cool them efficiently.
The proposed amendment would include a grace period, giving companies time to build the necessary power generation and storage systems. Businesses that fail to comply would face financial penalties, though these are expected to be relatively modest.
Even with a grace period, the cost and complexity of compliance could be substantial. Building private power infrastructure requires land, permitting, engineering, capital investment, and long-term maintenance. Energy storage systems, such as large-scale batteries, also remain expensive and need careful integration with industrial operations.
For TSMC, the issue is especially important because its global competitiveness depends partly on reliable and cost-efficient electricity. Semiconductor manufacturing already involves high capital spending, advanced equipment, strict environmental controls, and complex supply chains. Any increase in electricity-related costs could add pressure to margins, particularly as the company continues investing heavily in next-generation chip production.
The proposal could also affect Taiwan’s broader industrial landscape. Companies in steel, petrochemicals, optoelectronics, and data centers may need to rethink their energy strategies if the amendment becomes law. Some could accelerate renewable energy projects, while others may invest in backup generation, battery storage, or hybrid power systems.
Supporters of the policy may argue that forcing large power users to develop their own energy infrastructure could reduce strain on the national grid and improve resilience. It may also encourage faster adoption of renewable energy and distributed power systems.
However, critics are likely to question whether the timeline and cost burden are realistic, especially for industries that already face intense global competition. For companies like TSMC, the challenge is not simply generating electricity, but ensuring uninterrupted, high-quality power at the scale required by advanced semiconductor manufacturing.
The proposed law comes at a time when Taiwan’s role in the global chip supply chain is more important than ever. TSMC produces chips for many of the world’s leading technology companies and is central to the development of AI processors, mobile chips, high-performance computing products, and advanced consumer electronics.
If Taiwan moves ahead with the amendment, the decision could reshape how major industrial power users plan their future operations. For TSMC, it may mean higher energy spending, more infrastructure investment, and a more complex power strategy in its home market.
The key question now is whether lawmakers will approve the amendment as proposed, modify it, or introduce exemptions beyond schools and hospitals. Whatever the outcome, Taiwan’s energy policy is becoming increasingly tied to the future of its semiconductor industry.
