It is less affected by storms than other areas of the country and has established itself as Vietnam’s center for renewable energy. The province has good solar potential, with an average of 2,600 to 2,800 hours of sunshine per year. There are 15 wind power projects and 27 solar power projects in the province, with capacities of almost 800 MW and more than 1,808 MW. Another 54 MW solar project commenced operations back in April using SMA system solutions. The developer and operator of the 54 MW PV power plant in the southern Vietnamese province of Dak Nong is the country’s largest utility company, Vietnam Electricity (EVN). The solar power produced there is fed into the utility grid at a feed-in tariff (FiT) of $0.0935 per kWh.
