Automated Demand Response (ADR)
Taipower has been implementing Automated Demand Response (ADR) load management measures since 1987,and provides incentives to encourage users to cooperate in reducing peak power consumption, or to shift peak power consumption to off-peak hours, including pre-agreed load reduction periods (8 days selected in a month or periods selected in a day). The Company also takes immediately action to reduce loads when power supply is near capacity (guaranteed response, flexible response), and offers demand bidding measures (economic, reliable, combined) so that users can determine a preferential prices through bidding. Additionally, campus air conditioners are subject to an automatic demand response and combined with energy management systems that assist schools in smart energy saving.

Time-of-Use Rates
Time-of-Use (TOU) rates are different rates set for different periods of time. They reflect different power supply costs at different times, and guides users to reduce peak electricity consumption or shift electricity consumption to off-peak periods. Taipower has now used TOU rates for more than 40 years since they were first employed in 1979. At present, there are a total of 16 TOU rates, and all kinds of customers have TOU rates they can choose from. Among them, TOU rates have been fully applied to high-voltage users since 1989, while low-voltage users are free to choose whether they want to participate or not. In line with the deployment and application of AMI, Taipower introduced Residential and Commercial Simple Time-of-Use (TOU) Rates in 2016. In May 2021, the Company further launched Standard Three-Tiered TOU Rates for Lighting and Three-Tiered TOU Rates for Low-Voltage Electricity users to provide multiple options. In May 2022, Taipower introduced Electric Vehicle Charging and Swapping Facility Pricing to cater to the growing demand for electric vehicles. Together, these pricing plans offer users a diverse range of choices. The increasing use of renewable energy has led to changes in the peak and off-peak hours within the power system. Correspondingly, Taipower has adjusted the pricing signals for peak and off-peak periods, so that users can electricity consumption during nighttime peak hours. Additionally, co-generation plants can be called upon to generate electricity during peak hours at night. These altered measures were officially implemented in 2023.
Power Saving Performance
In order to encourage customers to implement energy conservation in practice, Taipower has employed powersaving incentives since July 2008 that prompt users to maintain power-saving motivation over the long term. In addition, a registration mechanism was introduced in 2018. Customers who sign up through the website, customer service hotline, or over the counter will receive a reward of $0.6 per kWh of electricity saved, with a minimum bonus of $84 per period (2 months). In the same year, the Power-Saving Reward Points app was launched. This allows users to collect points by participating in various energy-saving puzzle activities on the app. The points may be redeemed for prizes or to participate in sweepstakes. The goal is to promote the concept of power-saving among the public and form a powersaving culture and habits.
