In preparation for a sudden increase in power consumption during charring

In preparation for a sudden increase in power consumption during charring


Less than a month before the opening of the Tokyo Olympics, attention is focused on the available electricity supply and the amount consumers pay for electricity during the hottest months of the year.

However, while previous government quotes warned of tight demand, industry groups, including utilities and retailers, provided revised quotes that did not show a less dire situation, especially in July. did.

Kazuhiro Ikebe, Chairman of the Federation of Electric Power Companies of Japan, said, “We hope that we can secure a stable power supply without worrying, especially in the event of an unplanned power outage or various problems.”

Under national electricity law, utilities must maintain a minimum reserve requirement of 3% of maximum demand as a safety measure against sudden shortages. If the reserve ratio falls below 3%, power cannot be supplied when the maximum demand is reached, and there is a risk of rolling blackouts. Power companies generally reserve a reserve of 7% to 8% or more to prevent power plant troubles from reducing supply capacity and increasing demand due to high temperatures in the summer.

At the end of May, 8 out of 10 major Japanese electric power companies are expected to watch the Tokyo Olympics and the baseball tournament where I go to Koshien with air conditioners, 3.7% in July and 3.8% in August. I predicted that it would be a reserve rate. House. Kyushu Electric Power also predicted that the reserve requirement ratio in July was 3.7%, but it is forecast to rise to 6.8% in August.

The Ministry of Economy, Trade and Industry (METI) said the low forecast in late May was due to a decline in supply capacity due to the shutdown or closure of 10 old thermal power plants, including four operated by TEPCO. Electric power company Holdings (Tokyo Electric Power) operated by Kansai Electric Power (Kepco) and Tohoku Electric Power, and electric power company Holdings owned by Chubu Electric Power and Kyushu Electric Power respectively. The government has predicted that summer electricity demand will be the toughest since 2017.

However, on June 18, a more optimistic view came from the interregional coordination of transmission operators, a group of transmission and retail companies. KEPCO’s Mihama No. 3 reactor has already restarted, the Oi No. 3 nuclear power plant will be restarted by next month, and the two thermal neutron reactors in Tohoku and Shikoku are expected to return online soon. There is. It is available in Honshu, Shikoku and Kyushu than the Ministry of Economy, Trade and Industry predicted last month. However, some areas such as Tokyo and Tohoku will still face tensions in August.

The reserve requirement ratio for July from Tohoku to Kyushu is expected to be 5% to 6.2%. The ratio in the Tohoku / Tokyo area in August is expected to drop to 3.9%, while the ratio in central and western Japan is expected to rise from 6.1% to 6.5%.

Only Hokkaido and Okinawa were expected to have enough electricity to meet the demand. According to two estimates, the reserve rate of Hokkaido Electric Power is expected to be 16.2% in July and 23.9% in August, and the reserve rate of Okinawa Electric Power is expected to be 29.9% and 31.6% in July. August.

Consumers may be considering higher energy prices, regardless of the difference between utilities and retailers in how much electricity usage in July and August approaches the required reserves. In the simulation model of TEPCO’s household electricity bill, the average monthly bill in January is 6,317 yen. It is projected to rise by more than 600 yen to 6,973 yen by next month. This rise is due to crude oil prices, which were expected to continue rising until August.

Chief Cabinet Secretary Katsunobu Kato said at the end of last month, “It is difficult to continue your usual life, such as using an air conditioner, so please turn off the lights in the unused room and use it efficiently.”

A war over human resources broke out due to the boom in renewable energy …

A war over human resources broke out due to the boom in renewable energy …


Clean energy giants recognize that there is a shortage of workers with the skills needed to support ambitious growth plans.

According to Miguel Stillwell, CEO of Portuguese clean energy company EDP Renovaveis SA, the renewable energy employment market is overheating, making it difficult to find suitable candidates. I will. The company is one of the world’s leading adopters of green power and will employ 1,300 people over the next two years.

“There is a war over talent around the world, and the renewable energy sector isn’t strong enough given the high growth potential,” Stilwell said in an interview on May 28. It was.

As countries spend billions on renewable energy development, policy makers are relying on this sector to create new jobs that are essential to a post-pandemic economic recovery. According to the Clean Energy Research Group BloombergNEF, solar capacity is expected to triple by the end of 2010, and wind capacity is expected to more than double over the same period.

Leading green energy companies such as NextEra Energy Inc., Iberdrola SA, Enel SpA and EDP are leading the electrification competition in the global economy. However, several major oil companies have also begun to enter the sector, and BP PLC announced last month that it aims to fill 100 offshore wind jobs in the United Kingdom and the United States. This number could double by the end of the year.

EDP’s Stilwell states that engineering skills such as energy assessment, project management and project design are in high demand. A good business developer who understands clean energy technology is also a scarce resource. Other roles such as merger and acquisition management and back office operations can easily be hired from other industries.

“We need to bring people from other sectors, whether hiring directly from other sectors of the oil and gas, energy industry, or universities,” Stilwell said. “There is a lot of competition in the world”

According to Professor Jordi Lorca, engineering and chemistry graduates with a master’s degree in renewable energy from the University of Catalonia in Barcelona are often hired during or shortly after graduation. Universities are affiliated with other universities in Europe, and students are often hired to work in other countries such as the United Kingdom and Denmark, said Lorca, director of the university’s engineering research center. ..

“We need to quickly adapt the content of our energy transition and renewable energy programs so that our graduates can be competitive in the market,” says Llorca. “We are constantly looking at contracts and agreements with different industries to determine what we need.”

The university earned a master’s degree in hydrogen energy last year after the professor realized that few had the mechanics and chemistry skills that were immediately needed in a rapidly growing field. “Every time a new technology comes out, there are blank moments, but in just a few months we can put together a new program.”

Offshore wind farms are another area of ​​growth. The project involves the construction and maintenance of a wind turbine the same size as a skyscraper miles away from the sea. A single revolution of one of the giant blades can power your home for two days. The industry was pioneered in Europe but is now expanding rapidly to Asia and the east coast of the United States.

There are no experienced people in these new markets. So, according to Clint Harrison, director of renewable energy recruitment firm Taylor Hopkinson, developers are often dispatched to lead UK and European employees. But the business is on track. There is pressure to hire locally.

The difficulty of securing a well-trained workforce can be an industry bottleneck that is key to reducing emissions.

“There is a sense of urgency,” Harrison said. “The market is growing very rapidly and we need to have the right people across different projects and regions to keep projects moving forward and keeping up.”

According to a recent report from Robert Gordon University in Aberdeen, the UK alone will have about 200,000 skilled workers in the offshore energy sector, up from 160,000 today, to be needed by 2030. About half of the work is expected to be filled by transferees from the oil and gas sector, and about 90% of current workers in the fossil fuel sector can be retrained for renewable energy, he said. The author, Paul de Leeuw, said.

“The demand for renewable energy and energy transition courses is increasing rapidly, while the demand for oil courses is declining,” he said. “This is a social and industrial change reflected in the education system.”

As Japan turns to new basic energy policies, there are many challenges …


The government plans to adopt the following basic energy policy in June, which will serve as a guideline for the country’s medium- to long-term energy policy, sources said Friday.

The focus will be on how much the country can promote the use of renewable energy to achieve the new goal of reducing greenhouse gas emissions by 46% from 2013 levels to 2030. The goal was announced by Prime Minister Yoshihide Suga at the US-sponsored Online Climate Summit on Thursday.

The government believes that it needs to increase the use of energy sources other than fossil fuels. This includes increasing the share of renewable energies such as nuclear power and solar power to generate electricity.

The government’s current basic policy requires that the share of non-fossil fuel energy be raised to just below 50% by 2030. At a press conference on Friday, Hiroshi Kajiyama said that the percentage would definitely exceed that number in the next basic policy.

As an urgent solution, the government has fixed expectations for solar power. However, in mountainous countries, there are only a limited number of flat areas suitable for installing solar power generation equipment.

Meanwhile, only a handful of offshore wind farms are expected to be operational by 2030.

The government is also accelerating the introduction of next-generation thermal power plants that use hydrogen and ammonia, which do not emit carbon dioxide during the combustion process. However, as of 2030, their share will be as small as 1%.

A group of LDP lawmakers submitted a series of proposals to Mr. Kajiyama and Chief Cabinet Secretary Katsunobu Kato on Friday, including the construction of a new nuclear power plant and the reconstruction of an existing power plant.

However, 10 years after the triple meltdown at the Fukushima Daiichi Nuclear Power Station, which was hit by the tsunami of TEPCO Holdings in March 2011, the use of nuclear power will be increased due to prolonged safety concerns among the public. I continue to face the hurdle. The worst nuclear disaster in the country.

Only nine reactors have been restarted since the nuclear accident.

Even after a series of security flaws were revealed at TEPCO’s Kashiwazaki-Kariwa Nuclear Power Station earlier this year, public distrust has grown.

In fact, raising the proportion of nuclear power from 20% to 22% of the country’s national energy mix by 2030 is likely to be a daunting task for governments, observers say.

Tokyo Gas installs 19 offshore wind turbines in Carbo …


Tokyo Gas Co., Ltd. plans to install 19 offshore wind turbines along the coast of eastern Japan from 2024 in line with the government’s move. Carbon Neutral Goals by 2050Said the gas and power companies.

Wind turbines are installed in the waters near the coast of Ibaraki Prefecture and produce up to 159.6 megawatts. This is enough renewable energy to supply 70,000 households annually. The start date of the project has not yet been decided.

The 680-hectare wind farm, which will be built near the coast 1.6 kilometers from Kashima Port, is also funded by the Ibaraki-based wind farm and Bena Energy Holdings, a renewable energy company in Singapore. ..

In a press release, Tokyo Gas President Takashi Uchida said, “We aim to lead the growth of renewable energy that contributes to the realization of a sustainable society.”

Mr. Uchida said that he is working to provide a stable power supply by balancing the fluctuations in the output of power generated by renewable energy with gas-fired power generation, which is the core business.

Prime Minister Yoshihide Suga has pledged construction, saying that greening will be a major driver of growth for Japan, the world’s third-largest economy and the fifth-largest carbon dioxide emitter. Offshore wind farm Invest in technology to produce hydrogen fuel using renewable energy.

The government has set a goal to increase offshore wind power from just 20,000 kW today to up to 45 kW in 2040.
