What is expected to occur in the short term, in terms of boosting regulations on marine surveys?

Dr. Du Van Toan, director of the Marine Resource Management and Research for the Vietnam Administration of Seas and Islands, under the Ministry of Natural Resources and Environment

The ministry has finalised the draft decree amending and adding to several articles of Decree No.40/2016/ND-CP, which details a number of articles of the Law on Natural Resources and Environment of Sea and Islands as well as Decree No.11/2021/ND-CP.

New documents enhance regulations on evaluation procedures and issue a three-year written approval for the measurement, monitoring, and evaluation of marine resources. If the government permits, these documents could be released in the third quarter, facilitating the licensing of marine surveys and the construction of the first 3GW of offshore wind power experimental projects in the country.

Vietnam has an offshore wind power potential of up to 600GW, but marine survey licensing is plagued by numerous issues relating to criteria, capacity, experience, and construction capability. Therefore, only two wind measurement projects have been licensed to date. Permits for offshore wind energy surveying have been requested by 41 developers.

What is your key warning when it comes to carrying out surveys?

Due to the multiple phases of the survey, investors should not conduct multiple surveys simultaneously. The first survey is a wind measurement survey, while the geological and engineering survey should not be conducted until the state management agency confirms the project’s economic viability. The cost of a wind measurement survey is not excessively high, whereas geological surveys and engineering projects incur astronomical costs. Currently, the greatest obstacle for investors is the lack of clarity surrounding the policy and mechanism governing electricity price formation. Foreign investors have not yet been attracted by investment incentives, and power generation on the grid is dependent on the transmission capacity of the national power grid.

Can you tell us why wind measurement surveying is a priority?

Vietnam has offshore wind power potential, but not all seas are suitable for deployment. From Binh Dinh to Ninh Thuan provinces, and from Binh Thuan to Ca Mau provinces, and a portion of the central waters of the Gulf of Tonkin are the sea areas with the greatest wind energy potential, according to a study published last year.

The greatest wind energy in Vietnam is found in the coastal regions of Ninh Thuan and Binh Thuan. At the 100m level in this region, wind velocity exceeds 10 metres per second, and the wind energy density reaches 1,200-1,400MW per square metre.

Khanh Hoa (including Spratly Islands) is the province with the longest coastline at 370km, the largest sea surface area at 37,000 square kilometres, and the maximum wind energy resource at 259,000MW. Next is Ca Mau, which has 254km of coastline, 25,400sq.km of sea, and 203,200MW of estimated wind energy resources.

In addition, areas such as the islands of Phu Quy, Bach Long Vi, and Spratly Islands have abundant wind energy resources that can be used to develop large offshore wind power projects.

Will legal obstacles prevent the development of this energy source?

The legal structure for renewable energy and offshore wind is undergoing development. To accomplish the objectives of the Power Development Plan VIII, the legal framework for offshore wind power must be finalised as soon as possible, including the early adoption of a long-term marine spatial plan coordinated with other economic sectors.

Vietnam may gain knowledge from the global experience in developing and publishing legal documents to finalise the offshore wind power law. Australia and the United States both have offshore wind power regulations that limit the minimum and maximum area of a project. A survey permit is restricted to 700sq.km by Australian laws, for example.
