In the spirit of Resolution 98/2023/QH15 (Resolution 98) of the National Assembly recently issued, Ho Chi Minh City is implementing a project to use rooftops as public assets to install rooftop solar power systems. However, due to many shortcomings in the development mechanism, the development of this clean energy source still has many bottlenecks.
There are still many difficulties
In the spirit of Resolution 98 on piloting a number of specific mechanisms and policies to develop Ho Chi Minh City, the city needs to take advantage of opportunities to encourage businesses to convert to green production and produce green products. , especially businesses in industrial parks (IZs) and export processing zones (EPZs). However, Resolution 98 only allows the Ho Chi Minh City People's Committee to decide to use roofs in administrative agencies, public service units, and headquarters of agencies and units that are identified as public assets and not yet allowed to be developed. Rooftop solar power in industrial parks and export processing zones, while these places have large areas. The Ministry of Industry and Trade believes that with the mechanism of installing rooftop electrical systems for factories, factories, industrial parks, and export processing zones, it is necessary to have time to study policies, control capacity to suit the system, and avoid overheating. massively developed.
Another problem, according to Ho Chi Minh City Electricity Corporation (EVNHCMC), lunch break is the time when solar heat radiation is greatest, has the greatest ability to "generate" electricity, and during holidays, the amount of electricity produced will be redundant. Therefore, EVNHCMC recommends having an energy storage system during lunch breaks and holidays.
Mr. Pham Dang An, Deputy General Director of Vu Phong Energy Group, said that having policies and mechanisms to have a legal corridor to develop rooftop solar power is very necessary. Currently, many manufacturing enterprises, especially in industrial parks and export processing zones, are in dire need of investing in rooftop solar power to meet emission reduction goals, practice sustainable development, or meet green environmental standards. , requirements on the rate of use of renewable energy from the global supply chain... However, the mechanism to install rooftop solar power is still being developed by the Ministry of Industry and Trade, many solar power projects are installed. After 2020, there is still no solution.
Meanwhile, Mr. Dao Xuan Duc, Chairman of Ho Chi Minh City Industrial Park Enterprises Association, said that if the city took advantage of all the roofs of state agencies in the area to install solar power, it would be about 166MW. Meanwhile, Ho Chi Minh City has 18 industrial parks with an area planned by the government of about 7.000 hectares; In the coming time, it will expand to about 4.000 hectares. In 2019 alone, Ho Chi Minh City's industrial parks installed 80MW. After that, due to many difficulties in implementation and installation, related parties had to stop.
It is urgent to perfect the mechanism
Resolution 98 allows the headquarters of administrative agencies, public service units... to install solar power systems for self-use. Ho Chi Minh City People's Committee organizes this installation to ensure the landscape. According to calculations, the potential to install rooftop solar power systems in Ho Chi Minh City reaches about 5.081MWp, determined for 4 groups including: administrative agencies accounting for 3,27%, manufacturing accounting for 31,28%. , trade and services account for 3,1% and households account for 62,34%. Of which, the solar power capacity that can be installed on the roofs of administrative agencies and public service units in the city is about 160MWp.
At the press conference on Ho Chi Minh City's periodic economic and social issues that recently took place, Mr. Nguyen Phuong Duy, Deputy Head of the Energy Management Department of the Department of Industry and Trade, shared that by 2030, the city will have coverage of 50% of households. People use rooftop solar power. Currently, there are 14.210 rooftop solar power systems installed in the city, with a total capacity of about 358,3MWp. Regarding the mechanism for developing rooftop solar power, the Ministry of Industry and Trade is developing a draft plan to implement Power Plan 8, which includes the allocation of rooftop solar power capacity in localities to submit to the Prime Minister. approval.
At the same time, the Ministry of Industry and Trade is also developing a draft Government Decree on the mechanism to encourage the development of rooftop solar power, including regulations on the order and procedures for implementing the system installation. Rooftop solar power. The Department of Industry and Trade advised the People's Committee of Ho Chi Minh City to send an official dispatch to the Ministry of Industry and Trade to comment on the proposal to develop a Government Decree on a mechanism to encourage the development of rooftop solar power. The Department also proposed that the Ministry of Industry and Trade research specific policy mechanisms to develop rooftop solar power for the city. After the Government promulgates the mechanism to develop rooftop solar power, the Department of Industry and Trade will base on the allocated capacity in the implementation plan of Electricity Planning 8 and the Decree on the mechanism to encourage the development of rooftop solar power. house to advise Ho Chi Minh City People's Committee on implementation of installation in the city.
At this time, the Ho Chi Minh City Business Association (HUBA) proposed that the city need a mechanism to encourage rooftop solar power of factories, enterprises, projects... for self-use, not to sell electricity to organizations or individuals. other but connected to the national electricity system. This helps Ho Chi Minh City increase the amount of electricity supplied, businesses have more sources of income, and take advantage of existing facilities.
