A new energy trading platform (ETP) designed to help Taiwan Power Co (Taipower, 台電) harness privately owned reserve capacity and electricity storage services came online yesterday.
The platform makes it easier for private owners of electrical equipment, such as generators or power storage, to sell their energy resources to Taipower, effectively giving the state-run utility more flexibility and stability in the national grid.
“Suppose you are a factory owner with backup generators that hardly see any use,” said Wu Chin-chung (吳進忠), director in charge of power dispatching at Taipower. “When you are connected to the platform, that generator can become a part of Taiwan’s reserve margin and the owners get paid.”
Taipower already has existing deals in place with companies to purchase power storage and reward factories for time-shifting their power use to reduce peak usage rates.
The ETP platform would make future use of “private distributed electrical resources” quicker and more responsive, with an auction system that pays more in times of greater need, Wu said.
“We expect to consolidate a lot of diverse electric resources into our system and help maintain the stable operation of our grid, as well as ensure the fastest restoration of power in case of any accidents,” the company said in a statement.
Taipower already uses private electrical resources to match supply and demand, but, with the platform, more private owners are expected to join.
Energy storage systems are the fastest to respond, able to dispatch extra electricity to the grid within “one to 10 seconds,” Taipower said.
Others, such as generators, can start providing power to the grid within a half-hour, it said.
About 84.2 megawatts of “non-traditional reserve” are already on the books through individual contracts with Taipower.

Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), the world’s biggest contract chipmaker, booked its first-ever profit from its Arizona subsidiary in the first half of this year, four years after operations began, a company financial statement showed. Wholly owned by TSMC, the Arizona unit contributed NT$4.52 billion (US$150.1 million) in net profit, compared with a loss of NT$4.34 billion a year earlier, the statement showed.

VOTE OF CONFIDENCE: The Japanese company is adding Intel to an investment portfolio that includes artificial intelligence linchpins Nvidia Corp and TSMC Softbank Group Corp agreed to buy US$2 billion of Intel Corp stock, a surprise deal to shore up a struggling US name while boosting its own chip ambitions. The Japanese company, which is adding Intel to an investment portfolio that includes artificial intelligence (AI) linchpins Nvidia Corp and Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), is to pay US$23 a share — a small discount to Intel’s last close. Shares of the US chipmaker, which would issue new stock to Softbank, surged more than 5 percent in after-hours trading. Softbank’s stock fell as much as 5.4 percent on Tuesday in Tokyo, its
COLLABORATION: Softbank would supply manufacturing gear to the factory, and a joint venture would make AI data center equipment, Young Liu said Hon Hai Precision Industry Co (鴻海精密) would operate a US factory owned by Softbank Group Corp, setting up what is in the running to be the first manufacturing site in the Japanese company’s US$500 billion Stargate venture with OpenAI and Oracle Corp. Softbank is acquiring Hon Hai’s electric-vehicle plant in Ohio, but the Taiwanese company would continue to run the complex after turning it into an artificial intelligence (AI) server production plant, Hon Hai chairman Young Liu (劉揚偉) said yesterday. Softbank would supply manufacturing gear to the factory, and a joint venture between the two companies would make AI data
DOLLAR SIGNS: The central bank rejected claims that the NT dollar had appreciated 10 percentage points more than the yen or the won against the greenback The New Taiwan dollar yesterday fell for a sixth day to its weakest level in three months, driven by equity-related outflows and reactions to an economics official’s exchange rate remarks. The NT dollar slid NT$0.197, or 0.65 percent, to close at NT$30.505 per US dollar, central bank data showed. The local currency has depreciated 1.97 percent so far this month, ranking as the weakest performer among Asian currencies. Dealers attributed the retreat to foreign investors wiring capital gains and dividends abroad after taking profit in local shares. They also pointed to reports that Washington might consider taking equity stakes in chipmakers, including Taiwan Semiconductor
