According to Vietnamese media reports, Vietnamese Deputy Prime Minister Le Van Thanh said recently that the previously set photovoltaic power generation target for 2031-2045 was "too high" and should be appropriately lowered to make room for wind power generation.
In late February this year, Vietnam's Ministry of Industry and Trade proposed to set the country's installed power capacity at 146,000 megawatts from now until 2030, which is 9,000 megawatts less than the plan announced in November last year. The ministry also said that by 2045, Vietnam plans to have 352,000 megawatts of installed capacity, of which photovoltaics will account for 25 percent.
According to data from the Electric Power Company of Vietnam (EVN), as of 2021, Vietnam has ranked among the "Top 10 Global Photovoltaic Power Generation", reaching 16,504 MW, accounting for 2.3 percent of the world's total.
Dywedodd yr adroddiad hefyd fod y cynllun cyffredinol ar gyfer datblygu trydan yn Fietnam wedi mynd trwy bedair rownd o adolygiadau ers i'r drafft cyntaf gael ei gyflwyno gan Weinyddiaeth Diwydiant a Masnach Fietnam ym mis Mawrth y llynedd, ac nid yw'r llwch wedi setlo eto. Yn wyneb hyn, mae Weinyddiaeth Diwydiant a Masnach Fietnam wedi gofyn i'r awdurdodau uwch ohirio amser gweithredu penodol y cynllun tan ail chwarter eleni.
The same plan says that by 2045, renewable energy will account for 70 percent to 75 percent of Vietnam's national electricity capacity. At the 2021 UN climate change conference, Vietnam pledged to achieve net-zero emissions by 2050.
Dywedodd cyfarwyddwr Gweinyddiaeth Trydan ac Ynni Adnewyddadwy Fietnam, Huang Thien Dung, hefyd yn ddiweddar y bydd Fietnam yn cyflymu'r broses o drosglwyddo o danwydd ffosil i ynni glân ac adnewyddadwy. Tynnodd Tran Van Dong, Dirprwy Weinidog Gwyddoniaeth a Thechnoleg Fietnam, sylw at y ffaith bod gan Fietnam botensial enfawr ar gyfer datblygu ynni adnewyddadwy, gyda thua 217 GW o ynni gwynt ar y tir, tua 160 GW o ynni gwynt ar y môr, a thua 434 GW o gynhyrchu pŵer ffotofoltäig. .
Yn ôl y drafft diweddaraf o'r prif gynllun datblygu pŵer, erbyn 2045, bydd ffermydd gwynt ar y môr yn Fietnam wedi'u lleoli'n bennaf yng ngogledd a de'r wlad, gyda'r gallu gosodedig yn cynyddu 36 gigawat, gan gyfrif am 10.8 y cant o gyfanswm cynhyrchu pŵer.
Matthews Holland, senior manager at the Global Wind Energy Council (GWEC), said Vietnam's offshore wind power efficiency could exceed 50 percent, rivaling that of hydropower. According to GWEC estimates, Vietnam's initial investment for the first 4-5 GW offshore wind farms is up to US12 billion, but subsequent operating costs can be greatly reduced. The cost of generating electricity per 1,000 kWh of offshore wind in Vietnam is expected to be around US83, which will further drop to US58 by 2025.
Dywedodd Holland hefyd fod gan Fietnam arfordir hir o 3,260 cilomedr, yn ogystal â lefel y môr isel a chyflymder gwynt uchel (7 i 10 metr yr eiliad ar uchder o 100 metr), a'r amodau naturiol ar gyfer datblygu ynni gwynt ar y môr yw unigryw.
However, the United Nations Development Programme reminded the Vietnamese side that the latter should also pay attention to how to use new energy more effectively. Currently, Vietnam's unit energy consumption (the amount of energy required to produce 1 unit of GDP) is 1.5 to 1.7 times that of other countries in the region. That is, if Vietnam wants to be carbon neutral, it needs to cut manufacturing emissions in half. Moreover, with the increase of power generation, how to transmit and distribute safely, efficiently and energy-savingly is also a priority for Vietnam to be solved urgently.
