Significant increase in temperature, longer sunny season, rising sea level and stronger waves, southwest and northeast monsoon winds getting stronger in the future … have the potential to become an advantage for development projects. recycled energy.

Located in the tropical monsoon region, with the potential for abundant solar energy, the Mekong Delta is entering a period of strong solar power development. Especially, An Giang and Bac Lieu are the leading provinces in prioritizing the development of available renewable energy (wind and solar power).

The Mekong Delta has a monsoon, hot and humid climate with two distinct seasons. Each year, the delta receives an average of 2,200 – 2,500 hours of sunshine, with an average solar energy of 4.3 – 4.9 kWh / m2. The potential for clearly exploiting light energy is enormous. It is estimated that for every 1m2 of installing solar panels, it can collect 5 kWh of electricity per day. This light source is very stable, with more than 90% of the days of the year receiving sunlight that is strong enough to operate solar panels.

The Mekong Delta is also a low and flat peninsula, with a coastline and islands totaling approximately 700 km in length, the exclusive economic zone of the sea up to 360,000 km2, 10 times larger than the inland area. With favorable terrain and strong coastal wind conditions of about 5.5 – 6 m / sec at an altitude of 80 m (the height of wind power poles currently installed in Bac Lieu), the potential for energy exploitation coastal wind can reach from 1,200 – 1,500 MW. Not to mention wave energy, tidal energy, biomass energy are abundant in the Mekong Delta, but the locality has not been able to invest and exploit.

Bac Lieu knew wind power firstly because Bac Lieu 1 and Bac Lieu 2 wind plants have been in operation. This is the only province in the Mekong Delta where wind power projects have integrated into the national grid. However, Bac Lieu province’s wind power development plan for the period up to 2020, with a vision to the 2030 plan has been approved, the total potential capacity of the province is nearly 3,000 MW.

Ca Mau is not to be outdone. According to the approved plan, by 2030, with a vision to 2035, Ca Mau will develop wind energy to 3,600 MW, solar power connected to the national grid about 1,500 MW, biomass power such as wood power, garbage burning electricity. more than 60 MW.

In Tra Vinh, 6 wind power plant projects are planned at 6 coastal mudflats in Duyen Hai district and Duyen Hai town. In particular, there are 3 factories in Truong Long Hoa commune, two factories in Hiep Thanh commune and one factory in Dong Hai commune. By 2020, the cumulative total installed capacity will be around 270 MW, equivalent to 634 million kWh of wind power.

Bac Lieu also proposed that the Government consider and approve the investment in 500KV and 220KV transmission grids to synchronize power source projects in the province according to the socialization investment mechanism. In particular, priority is given to investors with large power source projects in the province to participate (similar to the case of investing in 500KV and 220KV transmission lines serving solar power projects in Ninh Thuan province.

The electric power transmission of wind power projects that have been approved for planning and being submitted for approval for additional planning has faced many difficulties due to the slow implementation of the projects of the 110 kV transmission line and transformer station, 220 kV transmission line and transformer station under the plan expected to be implemented in 2023.

Meanwhile, Ca Mau, Soc Trang and Tra Vinh also asked for a mechanism to develop wind power in the direction of: Prioritizing difficult construction areas, stabilizing electricity prices and giving private investment in power transmission grids. All aimed at releasing too much wind power on the national electricity transmission line.

In order to realize these goals, an important issue now is the need to build up and issue appropriate wind power tariffs. In fact, the price of wind power is hardly competitive with the price of traditional electricity generated from fossil energy.
