1. Foreword

• Actual demand

  The trend of climate change has become more and more significant in recent years. The rising average temperature in summer has led to record breaking power peak load. From the peak load of 37,057MW in 2018 to 39,608MW in 2023, it has increased year by year. The peak load in 2023 decreased compared with the same period last year (the peak load in 2023 was 39,608MW, a decrease of 985MW compared with 2022). The decrease in electricity consumption was mainly due to the global economy being affected by inflation and high interest rates in 2023, and the end market demand was weak. The industrial chain continues to destock, suppressing manufacturing production performance. In addition, Taiwan’s economic policy signals throughout the year are almost sluggish blue lights, so electricity consumption decreases. However, the above phenomena are mostly short-term temporary factors, and the power load will continue to grow in the long term.

• The impact of economic development on the environment

  Electric power is essential in modern society. Most production activities are driven by electric power, and the consumer activities also rely on electric power. However, the production and consumption of electricity will also bring environmental pollution and the increase of social external cost. Countries all over the world have put great emphasis on the problem of energy use based on the consideration of economic growth and people’s living environment.

2. Power saving service team formed by TPC

• Basis

  TPC has implemented the energy saving carbon reduction policies according to laws and regulations, in which it is stipulated that electricity enterprises should formulate annual plans for encouraging and assisting users to carry out power saving. Meanwhile, TPC has set up “Power saving service team” in each branch office since December 2018 for the purpose of strengthening of power sales business and expansion of customer service strategy. And the power saving potentials of users of high voltage and above have been investigated by using smart meter data analysis and simple diagnosis questionnaire.

• Targets of interview and setting of power saving KPI

  Because the standards of users’ energy auditing, which is using over 800kW per month, has been made by the Bureau of Energy, so users between 300kW-800kW are the prioritized targets of interview by us, and the number of 300kW-800kW high-voltage electricity consumers and the number of electricity sales in Taiwan (including outlying islands) in 2023 are shown in Table 1, and the key performance indicator (KPI) has been set. The target of 112-year electricity saving potential is 96 million kilowatt-hours (the actual result is 106.23 million kilowatt-hours); the number of households visited is 4,000 (the actual result is 4,527).

  

• Interview measure

  The interview includes the provision of power consumption analysis, power consumption statistics, and optimization of power factor in order to understand user situation (such as user manufacturing process, and the operation situations of air conditioning and lighting equipment in the factory), provide suggested measures, and establish trust relationship with users to serve as the basis for subsequent development of energy saving diagnosis technology service.
  

Up to 2023, the power saving service team has completed the interviews of a total of 13,214 customers with total power saving potential of 30,939 (Unit: 10,000 kW⋅h) as shown in the table below.

• Organizational adjustment

  In order to execute the plans and diagnosis of energy conservation, our organization has been readjusted of which Energy Conservation Section is from Chief of Maintenance to Chief of Sales for the Class-A branch (9 branches), and also renamed as Energy Conservation And Service Section on January 11, 2019. In addition, we also re-originized the structure of the Class-B branch (8 branches) as Class-A branches on August 23, 2022.

3.　Development of TPC’s energy saving diagnosis technical service capability

• Cultivation of energy saving diagnosis technical service personnel

  To facilitate the participation by power saving service teams of all branch offices in the energy saving diagnosis technical services, we have already completed 6 training courses as of December, 2023, and we’re going to hold 5 training courses this year. In the future, we will continuously promote the official license of Energy Service Company business to establish the traing system.

• Provide the service of energy diagnosis of each branches

  The Taiwan Power Energy Diagnostic Centers has been to be established in July last year in Taipei West Branch, Taichung Branch, and Kaohsiung Branch. Users with contract capacity of 500kW-800kW in the representative industries (such as manufacturing industry, department store industry, and hotel service industry) will be selected for energy saving diagnosis conducted by professional teams. The energy consumption tests will be completed with respect to energy consumption equipment in the factory by using test tools and survey form in order to provide improvement suggestions and conduct effectiveness assessment. At least 121 cases of diagnosis service reports has been to completed by the end of 2021, and 236 cases of diagnosis service reports has been to completed by the end of 2022, and 251 cases of diagnosis service reports has been to completed by the end of 2023.

4. Future plan

Establish and expand cooperation mechanisms with energy management companies. Low-voltage users use smart meters (Route B) combined with user-built energy management systems (EMS) to provide low-voltage users with multiple energy management value-added application services. In addition, high-voltage users are mainly in the manufacturing industry. We assist high-voltage users in taking stock of the energy-saving potential of energy-consuming equipment to achieve the goal of maximizing energy efficiency. In line with the government’s net-zero policy to help users save energy, the company will continue to expand energy-saving value-added services (such as measurement and verification M&V) and improve energy-saving coaching to increase competitiveness.
