1. In addition to the existing 467 kWp solar power generation system, the University expects to install an additional photovoltaic solar power system with a total capacity of 4,107.43 kWp by the end of 2024 (3,068.42.kWp for Jinde Campus and 1,044.64 kWp for Baoshan Campus), so that the total annual solar power generation reaches over 5,134,282 kWh.

2. Continuing our past power-saving achievements (saving approximately 18% of power consumption in the past 15 years), the University plans to invest more than NT$5,000,000 per year over the next 10 years into reducing the total power consumption of existing facilities, with a goal of achieving a 1% reduction in total power consumption each year (that is, more than 150,000 kWh per year). It is expected that, by 2029, the total annual power consumption of existing equipment will be reduced by at least 1,300,000 kWh, compared to 2022.

3. For Baoshan Campus, the total capacity of the solar energy system will reach 1,044.64 kWp by the end of 2024, and power consumption during peak hours will reduce to 800 kWh, thus attaining carbon neutrality during peak hours.

4. For Jinde Campus, the total capacity of the solar energy system will reach 3,068.42 kWp by the end of 2024, and power consumption during peak hours will reduce to 2,400 kWh, attaining carbon neutrality during peak hours.

5. NCUE will complete the installation of 2,087.75 kW and 601.5 kW of solar power in 2022 at the Jinde and the Baoshan Campuses respectively. Based on the average sunshine of 3.5 hours in the Changhua area of Taiwan, the total amount of electricity generated was (2,087.75+601.5)×365×3.5=3,435,517 kWh (kilowatt-hour). According to the Ministry of Economic Affairs, the carbon emission factor for electricity in 2022 was 0.495 kg CO2/kWh, therefore, carbon emissions were reduced by 3,435,517×0.495=1,700,580 kg. Peak electricity consumption during winter or summer vacation was lower than the amount of electricity generated by solar power. With a total installed capacity of 1,410 kWh, NCUE’s energy storage system can completely store the excess solar power generation and transfer the energy from renewable energy to nighttime use. Therefore, NCUE can not only harness renewable energy to achieve carbon neutrality during the daytime, but also increase the degree of carbon neutrality during the nighttime by utilizing a large-scale energy storage system to increase the utilization rate of renewable energy, as shown in Table 1.
