"Open source" and "cutting costs" to meet the challenges of power supply load
2023/6/26
Since the beginning of summer this year, a record heat wave "hit" many Asian countries, including India, Bangladesh, Thailand and Vietnam. Many countries have repeatedly set temperature records and issued warnings for heat and power outages. In response to the rising demand for electricity caused by high temperatures, many Asian countries have started from both "open source" and "cut back" to "cool down" the tight power supply situation.
High temperature warning in many countries
During the Dragon Boat Festival, high temperatures of over 40 degrees Celsius made people in northern China and the Yellow and Huaihe River area feel the power of the heat. According to the monitoring data of China National Meteorological Center, since June this year (as of 22nd), a total of 183 national meteorological stations daily maximum temperature exceeded the monthly extreme, 46 stations exceeded the historical extreme.
The "barbecue" pattern is not only affected by China. Since this summer, the temperature in many parts of Asia has "exploded", Laos and Vietnam recorded a high temperature of 43.5 degrees Celsius and 44 degrees Celsius respectively. The Copernicus Climate Change Service, the European Union's climate monitoring agency, recently said that the global average temperature in early June was the highest on record for the same period.
According to Pakistan's Tribune Express, from June 20 to 24, Pakistan faces hot weather across the country, with average temperatures across the country expected to be 2-6 degrees Celsius higher than the same period, with some areas reaching a maximum temperature of 40 degrees Celsius or higher, making it extremely unsuitable for travel or work. Pakistan's National Disaster Management Authority issued a heat wave weather warning, asking people to reduce travel and do protective measures.
CNN reported that a "once-in-200-years" heat wave caught Southeast Asia by surprise. On June 1, Vietnam broke the record for the hottest June in history, with temperatures reaching 43.8 degrees Celsius. Combined with high humidity, the heat in Southeast Asia has become even more unbearable and dangerous, the report said. According to the Thailand Post, the heat index (an index of combined air temperature and relative humidity) rose above 50 degrees Celsius in Bangkok's Bangna district, a weather phenomenon never seen before, while many other provinces in Thailand were equally hot.
Electricity supply challenges
Under the high temperature, people's demand for electricity surged, the power grid in many Asian countries under pressure, there is a tight situation of electricity. Singapore's "8world" news network reported that Asia's record-high temperatures have left many places unable to meet the load of electricity and disruptions have occurred.
Pakistan's ARY News TV reported on the 25th that the overall energy shortage has exceeded 6,500 megawatts due to the heat wave across Pakistan. Sources in Pakistan's power sector said the country's total electricity production was 20,400 megawatts, while demand reached 27,000 megawatts. The Daily Pakistan newspaper reported that in parts of Lahore, Pakistan, power outages are lasting more than 10 hours a day. Currently, Pakistan's national hydropower and nuclear facilities are operating at full power, accounting for half of the country's total power generation capacity, the report said. Due to the shortage of foreign exchange in Pakistan can not buy a sufficient amount of coal, natural gas and other energy, many thermal power plants available generating capacity has not been fully converted into electricity, becoming the main factor in the lack of electricity in Pakistan. In recent times, in Pakistan's capital city of Islamabad, daily power outages of 1-2 hours are still the norm. Many local households are equipped with emergency power systems to cope with temporary power outages so that they can still use low-power devices for lighting and cooling during power outages.
The heat wave hit several provinces in northern Vietnam, which are densely populated with industrial parks, and there was a bigger power supply gap than in previous years. Tran Viet Hoa, director of the Vietnam Ministry of Industry and Trade's Electricity Regulation Department, said at a press conference that the country's northern region faces an average daily power shortfall of 30.9 million kilowatt hours, with peak power shortfalls of up to 50.8 million kilowatt hours. The Wall Street Journal said the severe power shortage is hitting manufacturers who are flocking to Vietnam.
Bangladesh has also been facing severe power shortages due to a surge in electricity consumption caused by hot weather, coupled with a shortage of coal and natural gas supplies, while its tight foreign exchange has made fuel imports difficult, according to foreign media reports. The lack of electricity has reportedly threatened Bangladesh's important garment industry, which accounts for more than 80 percent of the South Asian country's exports.
"Cutting back" and "opening up" to deal with power supply tensions
In response to the power shortage brought by high temperatures, Asian countries to take the means to focus on "cutting" and "open source" two aspects.
According to Reuters 24 reported that India plans to launch a new policy for consumers of electricity in addition to the agricultural sector, cutting the price of electricity during the day and charging additional fees at night when electricity peaks. In the so-called "solar hours", electricity prices will be 10%-20% lower than normal, while in the peak hours of air conditioning use after people return home from work, electricity prices will be 10%-20% higher. The report said India is facing the most severe power shortage in six years, the new policy is aimed at encouraging price-sensitive consumers to reduce the running time of air conditioners at night, thereby reducing the pressure on fossil fuel power plants.
On the "open source" side, Bangladesh, India and Nepal are expected to reach a "landmark" power trade agreement. According to the "Nihon Keizai Shimbun" reported on the 25th, with India's consent, Bangladesh will import hydropower from Nepal through the Indian grid. If all goes well, the report said, the three countries will sign a tripartite agreement in July, which will save Bangladesh from facing power shortages. Nepal generates nearly 30 percent more hydropower than it needs during the rainy season and has been hoping to export some of its surplus power to Bangladesh. In addition to using existing Indian high-voltage lines, Nepal and Bangladesh are considering building a dedicated transmission line through India.
For power supply and sustainable development needs, many Asian countries are also developing clean energy. Reuters reports that the current record high temperatures across Asia highlight the need for power backup supplies, transmission system upgrades, tariff reforms and the push for clean energy. Energy research firm Wood Mackenzie predicts that the share of renewable energy in Asia's power mix, including hydropower, will reach 28 percent this year, with most of the growth coming from wind and solar, which together will account for 14 percent of the total.

A domestic investment company's energy industry analyst Lin Xiangjie 25 told the "Global Times" reporter, from a short-term perspective, many Asian countries will still maintain the traditional fossil energy and renewable energy synergistic development. In the medium and long term, focus on the development of renewable energy has been the general trend, especially the proportion of wind power and solar power is expected to be increasingly large. However, Lin Xiangjie also said, subject to weather changes and time changes, wind power and photovoltaic has the characteristics of instability, easy to cause a huge impact on the grid, the relevant countries need to improve the level of infrastructure, to create a more intelligent, flexible, strong grid, while strengthening the development of energy storage industry.
