• To make the grid safe and stable, Taipower established the energy trading platform. The Energy Trading Center responsible for operating the platform was officially inaugurated today (July 1) by Taipower Chairman Yang, Wei-Fuu (3^rd from the left) and President Chung, Bin-Li (4^th from the left).

With the rapid development of energy transformation and the increasing share of renewable energy in national power generation, Taipower continues to promote the digital transformation of smart grid in order to make the grid safe and stable. In recent years, an energy trading platform has been planned. First, a day-ahead ancillary service market has been launched to allow private distributed power resources to participate in bidding on the platform, turning them into virtual power units that can be dispatched at any time to maintain the stability of the grid. The Taipower Energy Trading Center responsible for managing the trading platform began its operation today (July 1), said Taipower. The energy trading platform is now opened for registration. After the procedures, such as written application and capability test, trading is expected to commence before the end of the year.

The Energy Trading Center was officially inaugurated today by Taipower Chairman Yang, Wei-Fuu and President Chung, Bin-Li, marking a milestone in power transformation. Taipower stated that in the past, the platform was mainly used to dispatch large-scale units to provide stable power supply. In the future, traditional power generation operators, installers of self-usage power generation equipment, users who can change their electricity-use behavior, and emerging energy storage equipment operators are able to participate in the bidding through the trading platform, allowing various types of distributed power resources to join the system to provide auxiliary service for maintaining the safe and stable operation of the power system, or assisting the power system to quickly return to normal after an accident.

• The energy trading platform of Taipower launched first the day-ahead ancillary service market to allow private distributed power resources to participate in bidding on the platform, providing auxiliary service for maintaining the safe and stable operation of the power system.

The day-ahead ancillary service market initially launched by the trading platform is a well-developed international trading system, mentioned Taipower, and it is now open for application. There are three trading items in the ancillary service, including "Regulation Reserve", "Spinning Reserve", and "Supplemental Reserve". Among them, "Regulation Reserve" requires the correction of system frequency deviation, and has the shortest response time, ranging from 1 second to 10 seconds. However, it has shorter duration. "Supplemental Reserve" refers to the increased operating reserve within half an hour after receiving a dispatching command in response to a sudden increase in load. The characteristics of "Spinning Reserve" are somewhere in between those of the two mentioned above. Those who are qualified for the trading platform can choose the most appropriate trading item, contributing jointly to the stability of the grid.

Taipower pointed out that the amendment of the Electricity Act shall include regulations for the energy trading platform. To accumulate experience, Taipower launched the "Interim Mechanism for Non-Conventional Units Participating in Spinning Reserve Auxiliary Service" in 2019, confirming the feasibility of distributed resources in conducting electricity trading. Currently, resources from electricity users such as Lealea Enterprise in Changhua, E-One Moli Energy, Enel X Taiwan, Mayaminer, Ancillary Power and AGRE Tech have registered a total capacity of 84.2MW, providing reliable support to the power system.

Last year, Taipower purchased large energy storage resources for the first time, enabling the adjustment of power system frequency more quickly and directly. Currently, Taipower is collaborating with companies including Skwentex International, TPE Energy, TCC Green Energy, and Tatung. During the power outages on May 13 and May 17 this year, Taipower dispatched 12MW of power from the collaborative partners, all of which could be quickly provided within one second to help stabilize the system frequency, becoming a new force for the grid.

The energy trading platform has incorporated the "Qualified Trader" system, said Taipower. In addition to cultivating professional talents, it also takes into account the fact that the auxiliary service market requires certain degree of professionality and technicality. Besides acquiring the "Professional Qualification Certificate", qualified traders must also meet the required qualifications. In the future, these qualified traders will assist private distributed resources to join the operation of the power system from the perspective of energy services.
