According to two people familiar with the matter, Vietnamese officials called on Apple supplier Foxconn to voluntarily reduce electricity consumption at its assembly plant in northern Vietnam by 30%. Last year, there was a power outage in northern Vietnam. Two other industry sources said that requests for energy saving measures have been sent to several manufacturers as a precautionary measure to avoid repeating the mistakes of last summer, when electricity shortages caused more than 1 billion US dollars in lost output. One of the people familiar with the matter said that the proposal to Foxconn was “an encouragement” rather than a requirement, and there was no impact on production. A person familiar with the matter said that the government has asked coal-fired power plants to postpone maintenance to meet higher electricity demand during the hottest months. People familiar with the matter did not specify who issued the request, when it was issued to Foxconn, or how long it would take to voluntarily reduce electricity consumption. A person familiar with the matter said that there are no restrictions on this requirement.
