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. This shift would materially escalate the electricity-related overheads for TSMC, the island’s largest power user. The move represents a significant change in how energy is delivered to heavy industry.
New law targets major electricity consumers
Taiwan’s Ministry of Economic Affairs is spearheading an amendment to the Energy Management Law, with the legislature scheduled to take up the amendment on July 22. The ministry wants to include all commercial entities that consume an electricity load of 5MW or above within the purview of this amendment. This group spans over 400 semiconductor, optoelectronics, steel, and petrochemical plants, as well as AI data centers.
Currently, 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 amendment will offer a grace period for the installation of the required energy infrastructure, with modest financial penalties imposed in case of non-compliance.

It is worth noting the sheer volume of infrastructure involved. TSMC retains the following commercially active chip fabrication facilities in Taiwan: six 12-inch GIGAFAB facilities that span Fab 12, Fab 14, Fab 15, Fab 18, Fab 20, and Fab 22; four 8-inch wafer labs that include Fab 3, Fab 5, Fab 6, and Fab 8; and one 6-inch wafer fab, called Fab 2. The company also maintains a number of advanced packaging plants. 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.
Impact on scale and cost
As one of the largest consumers of electricity in Taiwan, TSMC will soon lose the economies of scale that come with grid-based power. If its gigantic network of fabs now has to be powered by captive power plants, TSMC will face higher operational costs and logistical challenges. While the company has the capital to invest in on-site generation, the administrative burden of managing a private grid for multiple facilities across the island is substantial. The financial penalties for non-compliance are set at modest levels, but the operational risk of failing to meet the new standards could be far greater for a company of this size.
