In order to continue to meet the nation's stable electricity demand, Taipower must maintain a dynamic balance between power system generation and consumption and grid frequency every minute of every day. In the past, most of the sudden power changes were rescued by large generating units. In July last year, Taipower joined hands with enterprises to build "Asia's first" power frequency adjustment energy storage system, breaking away from the existing thinking of building power plants and buying units for operation. Taipower inaugurated its power trading platform in July this year and recruited a wide range of "power god teammates" from the public. Today (15), the power trading platform enters into official operation, which is also an epochal milestone in Taiwan's power transformation. Taipower said that the power trading platform refers to the electricity market structure planning of advanced countries, such as the United States, Britain, and Australia, and first introduces auxiliary service trading to attract private decentralized electricity resources into the grid and create an electricity sharing economy through the operation of the electricity trading market. The trial operation has contributed nearly 8,000 MW-hr (million watt-hours) of auxiliary service capacity and over $4 million in transactions in the past month, with the future business potential of up to $10 billion to help stabilize the national power system.

This afternoon, Taipower held a ceremony to celebrate the opening of the power trading platform at the Taipower Building. The chairman of Taipower, Mr. Yang, Wei-Fuu, the president of ITRI, Mr. Edwin Liu, and other VIPs from all walks of life gathered at Taipower's power trading center, the headquarters of the power trading platform, to celebrate the ceremony by banging the gong, just like the stock market. They together witnessed the official operation of our power trading platform and ushered in a new era of power trading in Taiwan.

• Taipower held a ceremony today to celebrate the launch of the power trading platform. The ceremony was attended by the president of ITRI, Mr. Edwin Liu (from left), the chairman of Taipower Yang, Wei-Fuu, Ministry of Economic Affairs Secretary General Chen, I-ling, and Taipower Vice President Chang Chung-Liang. Following the example of the securities market by banging the gone, Taipower celebrated the official opening of the electricity trading platform in Taiwan.

Taipower explained that in response to the continuous increase in renewable energy and in order to take care of energy transformation and stable power consumption nationwide, Taipower has been conducting internal electricity bidding trials with its existing generating units since 2014 and is actively planning to establish an electricity trading platform in response to the Electricity Law announced in 2017. In year 2019, the "temporary mechanism for non-traditional units to participate in the immediate standby auxiliary service" will be launched, with a total of 84.2MW of private power resources invested. In year 2020, Taipower will work with private enterprises to build "Asia's first" automatic frequency control (AFC), which is like a "virtual power plant" that can provide 15MW of power in one second, and gradually prove and establish a viable model for decentralized power to participate in power trading.

Taipower pointed out that Taiwan's power grid is an independent grid, and the stability of the grid must be self-sufficient, and the existing power supply is dominated by large generating units. With the birth of the electricity trading platform, electricity resources that were originally built in the private sector were brought into the electricity market. Through trading, the added value of these resources would be raised, such as traditional power generators, self-use power generation equipment installers, customer-side demand response (those who can adjust power consumption), and grid-connected storage equipment owners and other diversified decentralized private power resources can participate in the power trading platform and provide supplementary services through competitive bidding, helping to stabilize the nationwide power system, and at the same time gaining service revenue, creating a "power-sharing economy". The business opportunities are roughly estimated to be in the tens of billions of dollars.

Taipower said that the power trading platform was first introduced into the Day-Ahead ancillary services market, where bids are made on the previous day for the next day's electricity demand. Taipower settles the service fees to the participating companies on a monthly basis based on the actual dispatched power capacity and service quality. Since the trial operation in July, four operators, including Tatung, Delta Electronics, Ancillary Power Scheduling Services, and Aerospace Industrial Development Corporation, have completed the relevant capability test and officially become qualified traders and started bidding, bidding and online operation. 14MW of energy storage equipment have participated in the FM backup service market; 1.4MW and 1.6MW have participated in the real-time and supplemental backup service market respectively, and 17MW of private power resources have participated in the trial operation. The total transaction volume of the trial trading has been close to 8,000MW-hr so far, and the transaction amount is over 4 million dollars.

Taipower pointed out that the auxiliary service market has immediate and flexible characteristics, which can help adjust the daily power supply and demand balance. In addition to those who have already participated, three other companies have applied for a total of 14.9 MW of participation and are currently conducting relevant tests, while dozens of potential companies are actively inquiring about preparations. In addition, Taipower expects to start "spare capacity market" transactions next year, allowing spare capacity providers and volunteers to trade or match freely through the platform to strengthen long-term power supply stability.
