Demand-Based Bidding
"Demand-Based bidding" refers to the practice of allowing users to sell backthe electricity they save to Taipower during periods of high system load. Users bid their desired price, and Taipower determines the winning bidder based on the lowest bid. If the winning bidder successfully reduces their electricity consumption during the designated period, they are eligible for a reduction in their electricity bill. This measure empowers users by allowing them to set their own price, stimulating their potential for reducing electricity usage. It helps improve the system load profile, thereby delaying the need for new power generation facilities and reducing the risk of potential power shortages.
In the future, Taipower plans to provide more real-time power consumption information through smart meters, and to refine demand response scheme designs. For example, the Company will coordinate the increasing number of renewable energy grid-connections to adjust the periods for users to suppress power consumption. This will provide more flexible resources for the power system. Taipower will also be reviewing and piloting a variety of demand response plans.

Time-of-Use Rates
In line with the deployment and application of smart meters, Taipower introduced Residential and Commercial Simple Time-of-Use (TOU) Pricing in 2016. In May 2021, the Company further launched Standard Three-Tiered TOU Pricing for Lighting and Three-Tiered TOU Pricing for Low-Voltage Electricity to provide users with 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 p lans offer users a diverse range of choices.
Additionally, with the increasing generation of renewable energy, there have been changes in peak and off-peak hours within the power system. To accommodate this, Taipower has adjusted the peak and off-peak periods for time-of-use pricing. These 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.

The performance of power-saving rewards is derived from the statistical data of customers who have logged in and completed power-saving reward activities (4.22 million customers in 2020, 4.34 million customers in 2021, and 4.32 million customers in 2022).
