Using 2020 as the base year, the Institute has established short-, medium-, and long-term energy management targets, aiming to reduce the proportion of purchased electricity by 22% by 2030. This effort is driven by three major energy-saving strategies, combined with the installation of photovoltaic systems and the application of self-developed energy-saving technologies, to implement green operations and achieve net-zero objectives. In 2024, ITRI strengthened its energy management system and the management mechanisms for significant energy use in accordance with the ISO 50001:2018 international standard. In recent years, large-scale projects have driven increased energy consumption in infrastructure. In response, the Institute has actively implemented ISO 50001, alongside self-initiated energy-saving, carbon-reduction measures, and low-carbon technology applications, ensuring both energy performance and environmental sustainability.

ITRI’s operations focus on technology R&D and application promotion, with workspaces primarily consisting of laboratories and offices, where electricity accounts for approximately 92.90% of total energy consumption. Compared with the 2020 base year, in 2024 purchased electricity decreased by 11.3%, per capita energy intensity declined by 10.77%, overall energy intensity fell by 26.97%, and total energy consumption dropped by 7.37%. Compared with 2023, purchased electricity decreased by 2.35%, per capita energy intensity declined by 3.89%, overall energy intensity fell by 16.05%, and total energy consumption decreased by 0.79%.

ITRI advances energy management through a dual approach of energy-saving initiatives and management systems. By leveraging smart monitoring, equipment upgrades, and the adoption of energy-saving technologies, the Institute improves energy efficiency and reduces unnecessary consumption, while maintaining energy-saving outcomes through a formal energy management system. Energy management is a core component of the Safety, Health, Quality, Environmental and Energy Integrated Management System. In 2024, ITRI further strengthened energy performance indicators and established energy baselines, conducting system diagnostics and planning as a foundation for implementing deep energy-saving measures. Presenting and managing energy performance remains a primary challenge for ITRI. In 2024, the Institute conducted energy consumption analyses and assessments across departments, buildings, and common energy-intensive equipment, prioritizing high energy-consuming buildings for energy management. Energy reviews were carried out to monitor energy use and facilitate performance management.

Building upon the experience gained in establishing energy baselines and conducting reviews in 2024, the Institute has developed consistent processes and methodologies. Starting with the most energy-intensive buildings, designated energy management representatives from each unit will gradually expand the scope of reviews to identify significant energy uses and implement action plans. Through these efforts, the Institute aims to establish an energy management system aligned with both operational practices and the requirements of ISO 50001, thereby ensuring the continuous advancement of deep energy conservation.

In 2022, the Institute formally established a Carbon Reduction Fund to advance the transition toward low-carbon development. By linking carbon reduction investments with unit performance, the Institute allocated NT$129 million from internal funding in 2024 to acquire net-zero emission equipment. These investments targeted improvements in spatial environments, lighting systems, power and other energy monitoring, ventilation, and wastewater treatment facilities. As a result, the Institute achieved multiple energy-saving outcomes, including LED lighting coverage of 86.72%, installation of a 400 RT dual compressors active magnetic bearing centrifugal water chiller in Building 77 of ITRI Headquarters, and optimization of the cleanroom airside system in Building 67. Collectively, these measures reduced annual electricity consumption by 3.3564 million kWh, contributing tangibly to environmental sustainability and reinforcing the Institute’s position as a benchmark in high-efficiency energy management.

The Institute continues to promote the development of a net-zero sustainable demonstration campus, identifying renewable energy as a key strategy toward achieving net-zero emissions. Efforts have been dedicated to the transition of electricity supply, the deployment of renewable energy facilities, and green electricity market matching to increase the green electricity transfer rate. In 2024, ITRI continued to deploy on-campus renewable energy using its in-house GEL’s Tunnel Oxide Passivated Contact Technology for photovoltaic installations, adding 1,000 kWp of installed capacity, bringing the cumulative total to 4,272 kWp, with contracted capacity accounting for 19.19%.

The Institute adopted simulation systems during the PV planning phase to determine the optimal installation capacity and tilt angle. Professional operation and maintenance (O&M) management, together with real-time monitoring systems, were implemented to compare solar irradiation with actual output, enabling prompt anomaly detection and corrective action (29 cases). As a result, generation efficiency outperformed the regional average. In 2024, the Institute’s total solar PV generation increased by 241.05% compared to the 2020 base year, reaching 4.84 million kWh. Additionally, 500 Renewable Energy Certificates (RECs) were retained to support the Institute’s commitment as a green enterprise.

2. Statistics include the data of ITRI Headquarters, Kuang-Fu Campus, ITRI Southern Region Campus, ITRI Central Region Campus, Southern Taiwan Innovation & Research Park, and Shalun Green Energy Technology Demonstration Site.

In collaboration with the Energy Administration, MOEA, and the Tainan City Government, the Institute has jointly developed the net-zero vision for the Shalun Smart Green Energy Science City, establishing the campus as a net-zero demonstration zone with green energy as a showcase. By actively introducing green electricity for use at the Shalun site, the Institute implemented zero-carbon power demonstration applications, shaping the site into a premier national demonstration field for green energy technologies, fulfilling the RE100 corporate responsibility initiative and aligning with the Institute’s corporate vision. In 2024, the Institute successfully achieved the RE40 target. Annual green electricity demand totaled 2.698 million kWh, with 2.7317 million kWh obtained through a combination of self-generated green power, green power purchases, and Renewable Energy Certificates (RECs), accounting for approximately 40.5% of total electricity consumption.

Note: RE40 refers to ''Renewable Energy 40,'' meaning an organization achieves a 40% share of renewable energy consumption.
