Taiwan now intends to ask all large commercial consumers of electricity to install their own power generation and storage infrastructure, barring a carve-out for schools and hospitals, materially escalating TSMC's electricity-related overheads in the process.
As one of the largest consumers of electricity in Taiwan, TSMC will soon lose the economies of scale that come with grid-based power
Taiwan's Ministry of Economic Affairs is now spearheading an amendment to the Energy Management Law, with the legislature scheduled to take up the amendment on July 22.
Do note that Taiwan's "Renewable Energy Development Regulations" and their related sub-laws already require large commercial consumers to offset 10 percent of their electricity consumption via renewable resources.
The new amendment, however, will now require all large consumers of electricity to install their own power generation and storage infrastructure.
The ministry wants to include all commercial entities that consume an electricity load of 5MW or above within the purview of this amendment, spanning over 400 semiconductor, optoelectronics, steel, and petrochemical plants, as well as AI data centers.
Of course, as the biggest consumer of electricity in Taiwan, TSMC will be most impacted if the proposed amendment becomes law. After all, if its gigantic network of fabs now has to be powered by captive power plants, TSMC will lose out on the economies of scale that come with grid-sourced power.
The amendment will offer a grace period for the installation of the required energy infrastructure, with modest financial penalties imposed in case of non-compliance.
For the benefit of those who might not be aware, TSMC retains the following commercially active chip fabrication facilities in Taiwan:
- 6x 12-inch GIGAFAB facilities that span Fab 12, Fab 14, Fab 15, Fab 18, Fab 20, and Fab 22.
- 4x 8-inch wafer labs that include Fab 3, Fab 5, Fab 6, and Fab 8.
- 1x 6-inch wafer fab, called Fab 2.
The company also maintains a number of advanced packaging plants. What's more, TSMC consumed around 25.55 billion KWh of electricity in Taiwan in 2024, which accounted for around 9 percent of the country's total electricity consumption! Replacing this level of consumption with electricity sourced from captive power plants will be a herculean task in its own right.
