[The world's largest high-voltage direct mounted energy storage project] Recently, the world's highest and largest high-voltage direct mounted energy storage system, the Huaneng Hainan State 150 MW/600 MWh energy storage project, was successfully connected to the grid and achieved full power operation in Hainan State, Qinghai Province at an altitude of 3000 meters. This project is invested and developed by Huaneng Qinghai Branch, and developed and constructed by Huaneng Qingneng Institute. The total installed capacity is 150 MW/600 MWh. It is a shared energy storage project on the grid side of three new energy projects newly built by Huaneng Qinghai Branch. The overall project adopts the 35 kV high-voltage direct hanging energy storage technology led by Qingneng Institute, with a single unit capacity of 25 MW/100 MWh. It can store 600000 kWh of electricity on a single charge and can independently accept grid regulation. It has the characteristics of high voltage level, large single unit capacity, few AC/DC parallel connections, and few communication levels. It does not require a power frequency transformer. On the basis of improving battery capacity utilization and reducing battery parallel safety risks, the system efficiency is improved by 4% to 6%, and it can achieve fast response within 10 milliseconds. In addition, to adapt to the special environment of Qinghai, the project has focused on correcting insulation and electrical clearances at high altitudes to ensure safe, stable, and efficient operation under high-altitude conditions. After the project is put into operation, it can effectively stabilize the fluctuation and intermittency of the output of new energy power stations, provide peak shaving, frequency regulation, power assistance and other services for the power grid, and effectively improve the quality and safety level of the power grid.

• [Qiongzhou Strait transportation new energy vehicle ship successfully docked]
• On the afternoon of October 8th, under the on-site escort of the Guangdong Zhanjiang Maritime Bureau's "Haixun 0927" ship, the first flatbed cargo ship dedicated to the transportation of new energy vehicles in the Qiongzhou Strait, the "Green Source No. 1" ship, slowly entered the Xuwen Hai'an New Port, marking the successful trial operation of the ship's roll on/roll off transport route in the Qiongzhou Strait. It is reported that the deck cargo ship "Green Source No.1" has a total tonnage of 6731, a net tonnage of 3769, a length of 125.8 meters, and a width of 28 meters. The ship adopts a single-layer deck design, which can carry more than 160 new energy vehicles on a single voyage under full load conditions. The parking capacity is about 60% higher than that of existing passenger and roll on/roll off transport ships. The ship is planned to be deployed on the route from Hai'an New Port in Zhanjiang to Xiuying Port in Haikou. After being put into operation, it will add a new mode of sea transportation for new energy vehicles in the Qiongzhou Strait and effectively alleviate the tense situation of insufficient capacity for new energy vehicle transportation during the peak period of cross sea vehicle transportation in the Qiongzhou Strait.

• [Malaysia's energy transition has made progress]
• On October 9, 2024, Malaysian Deputy Prime Minister Fadhila stated that Malaysia has made progress in improving energy efficiency and that "energy conservation" has become the key to energy transition. Meanwhile, Malaysia will promote the ASEAN power grid as a key topic of discussion at the ASEAN Energy Ministers' Meeting. At the 2024 Asia Power and Energy Exhibition, which opened on the 8th, Fadhila revealed that as of June, Malaysia has saved 8769 gigawatt hours of electricity, worth over 2.2 billion ringgit, and plans to reduce 38 million tons of carbon dioxide emissions by 2025. In addition, the Malaysian government has approved the establishment of an energy exchange aimed at selling green electricity to neighboring countries. As the rotating chair of ASEAN in 2025, Malaysia will promote the construction of the ASEAN power grid to promote the promotion of renewable energy and enhance the resilience and reliability of electricity supply in ASEAN member countries.
