Taiwan's MOEA mandates energy audits for major users above 800 kW; five-year plans due by Q1 2028.
Taiwan is widening its energy efficiency requirements, with the Ministry of Economic Affairs mandating energy audits for major power users with contracted capacity above 800 kilowatts under regulations announced on 18 May.
The new rules apply to about 4,900 major energy users, expanding obligations already in place for companies that must achieve average annual electricity savings of 1% or 1.5%, depending on contracted power capacity.
Under the "Regulations Governing Energy Audit and Establishment of Energy Conservation Plans for Energy Users", the audits must be carried out between 2026 and 2027. After completing the audits, affected users will need to submit five-year energy conservation plans to MOEA by the first quarter of 2028 and then file annual progress reports.
The regulations are part of Taiwan's "Deep Energy Saving Action Plan", which the Executive Yuan launched in 2024 with a goal of saving 20.6 billion kilowatt-hours (kWh) of electricity over four years.
Progress figures released in the article show the plan had delivered combined savings of 12.068 billion kWh as of April 2026. Major energy users accounted for more than 2.9 billion kWh of that total.
From January to April 2026 alone, electricity savings reached about 1.17 billion kWh. According to the article, that reduced natural gas demand for power generation by roughly 164,000 metric tonnes, equivalent to the gas supply from about 2.7 liquefied natural gas tankers.
"Through mandatory energy audits and five-year energy conservation plans for major energy users, the energy-saving potential in energy-intensive facilities can be fully identified", MOEA said in a statement.
MOEA also said the measures would support the development of energy audit technologies and energy-efficiency services.
Audit teams may include professionals from accredited organizations, academic institutions, research institutes, or licensed professional engineers. These teams will review existing equipment and identify opportunities for energy savings across facilities, MOEA said.
To help companies comply, MOEA plans to create an Energy Audit Information Section where major energy users can find suitable audit service providers.
The government is also offering financial support for energy-saving investment. That includes investment tax credits under Article 10-1 of the Statute for Industrial Innovation, which broadens eligible projects and increases the maximum investment deduction cap to $62.3m (NT$2b). Subsidies will also be available for Energy Service Company performance-guaranteed projects, waste heat and cold recovery projects, and energy-efficient power-driven utility equipment.
The article listed the exchange rate as US$1 = NT$32.10.
