Japan asks households, companies to conserve electricity during winter

Japan said on Tuesday it will ask households and companies across the country to conserve electricity within “a reasonable range” during the peak winter demand season to alleviate a possible power crunch in the world’s third largest economy.

Between Dec. 1 and March 31, users will be asked to turn off unnecessary lights, wear layered clothing indoors and turn the heating temperature lower.

Japan’s power supply has been tight in recent years as nuclear power plants have been slow to restart after the 2011 Fukushima nuclear disaster. Rising risks that the Russia-Ukraine war could further disrupt global fuel supplies have also added pressure this year.

“The power situation remains severe though we expect to be able to secure the reserve ratio of 3% during the winter,” said Yasutoshi Nishimura, Japan’s industry minister, referring to the minimum generation power capacity required for stable supply.

“We won’t set a numerical target, but will ask for power conservation and energy saving for the entire nation,” he told a news conference.

Other measures such as rebooting idled power plants, making effective fuel procurement and encouraging power conservation through a point programme were also being implemented, he said.

Nuclear power plants have grappled with tighter regulations since the Fukushima nuclear disaster, while power supply has also been curbed by a series of closures of aging thermal power plants, in part to meet Japan’s carbon (CO2) emissions reduction goals.

The resource-poor country also faces the growing risk that a prolonged Russia-Ukraine war and widening Western sanctions on Moscow could disrupt supply and cause fuel shortages.

Japan’s electricity supply outlook for the winter has improved after it secured extra power generation capacity through public auctions, national grid monitor OCCTO said in September.

Imagine if you could put an ultra-thin, transparent solar sheet on your window to generate energy, not just from sunlight but also artificial lights from inside your room? Seen as the most promising next-generation solar cell, this technology, called perovskite, is exactly what Japanese start-up Enecoat Technologies is trying to develop. Start-ups such as this are called "deep tech". They are small firms who are merging high-tech engineering innovation with scientific discovery. The hope is that it will lead to the development of transformational products.

The headwinds for yen are getting stronger and threaten to push the currency to a six-year low against the dollar. A spike in global commodity prices spurred by Russia’s invasion of Ukraine is likely to worsen Japan’s trade deficit as the country is a net oil importer and may push the yen to 120 per dollar this year, said Mitsubishi UFJ Morgan Stanley Securities. Mizuho Bank Ltd. and TD Securities both predict the currency will weaken to 117 by the end of June, from 114.82 on Friday.
