Taiwan’s biggest power company, telecom operator and IT firms are designing metering and communication systems to link air conditioners and lighting systems with computers and mobile phones.
Efficiency gains from the scheme could save millions of tonnes of carbon emissions.
The technologies will enable property owners to set “energy budgets” for their buildings, send electricity price change updates to consumers via cable TV or mobile phone and let telecoms firms start providing power optimization services.
These systems are likely to be crucial to recently announced moves in the UK, the US and China to build “smart grids,” because Taiwan develops and manufactures many of the world’s electronic chips and components.
Taiwan Power (台電), the nation’s utility, will launch a small-scale research study of less than 100 homes that will be rapidly expanded to tens of thousands of homes in the next two or three years.
“Taiwan is the place to do this because we already have a strong information infrastructure and we can manufacture fast and at low cost,” a government official said.
She estimated that the country could save 10 percent of its energy simply by switching off idle devices and another 10 percent to 20 percent through better management of air conditioning.
“Human beings are lazy,” the official said. “If you make adjustments automatically, then you can save a great deal.”
In trials, Taiwan Power is experimenting with wireless devices so smart meters can communicate with all the devices in a house.
Ho Wu-chi of the Industrial Technology Research Institute said Taiwan aims to develop a two-way system of communication between electricity suppliers and users.
Consumers will receive frequent updates of price fluctuations so they can trim usage at peak times. While the UK aims to do this through dedicated displays in each house, Taiwan wants to do it more cheaply by using existing devices such as cable TV, mobile phones and computers.
“We are putting in place a smart meter policy. If we want to go into the international market, we have to show first that we can do it ourselves,” Ho said.
Within five years, he said that more than 5 million smart meters would be installed at a cost of NT$50 billion (US$1.55 billion).
In the international market, the business potential is enormous. For each of the next 30 years, Ho estimates the world will need 30 million meters, each retailing for between US$50 and US$100.
The domestic unit of the Chinese-owned, Dutch-headquartered chipmaker Nexperia BV will soon be able to produce semiconductors locally within China, according to two company sources. Nexperia is at the center of a global tug-of-war over critical semiconductor technology, with a Dutch court in February ordering a probe into alleged mismanagement at the company. The geopolitical tussle has disrupted supply chains, with some carmakers reportedly forced to cut production due to chip shortages. Local production would allow Nexperia’s domestic arm, Nexperia Semiconductors (China) Ltd (安世半導體中國), to bypass restrictions in place since October on the supply of silicon wafers — etched with tiny components to
Singapore-based ride-hailing and delivery giant Grab Holdings Ltd has applied for regulatory approval to acquire the Taiwan operations of Germany-based Delivery Hero SE's Foodpanda in a deal valued at about US$600 million. Grab submitted the filing to the Fair Trade Commission on Friday last week, with the transaction subject to regulatory review and approval, the company said in a statement yesterday. Its independent governance structure would help foster a healthy and competitive market in Taiwan if the deal is approved, Grab said. Grab, which is listed on the NASDAQ, said in the filing that US-based Uber Technologies Inc holds about 13 percent of
Taiwan is open to joining a global liquefied natural gas (LNG) program if one is created, but on the condition that countries provide delivery even in a scenario where there is a conflict with China, an energy department official said yesterday. While Taiwan’s priority is to have enough LNG at home, the nation is open to exploring potential strategic reserves in other countries such as Japan or South Korea, Energy Administration Deputy Director-General Chen Chung-hsien (陳崇憲) said. While the LNG market does not have a global reserve for emergencies like that of oil, the concept has been raised a few times —
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday received government approval to deploy its advanced 3-nanometer (3nm) process at its second fab currently under construction in Japan, the Ministry of Economic Affairs said in a news release. The ministry green-lit the plan for the facility in Kumamoto, which is scheduled to start installing equipment and come online in 2028 with a monthly production capacity of 15,000 12-inch wafers, the ministry said. The Department of Investment Review in June 2024 authorized a US$5.26 billion investment for the facility, slated to manufacture 6- to 12nm chips, significantly less advanced than 3nm process.
