Facts ‘n’ Figures: Coal, nuclear and renewables to boost Vietnam’s electricity capacity

Vietnam is poised to transform its electrical power generation mix over the next two decades, as it modernizes the country’s agrarian economy to become a more industrialized nation. To accommodate greater industrial expansion and support energy security goals, Vietnam is boosting its total electricity generating capacity. As part of its capacity expansion, Vietnam plans to add substantial coal-fired capacity and build the first nuclear reactors in Southeast Asia, and the first offshore wind farm in Asia.

Vietnam’s rapid economic growth, industrialization and export market expansion have been accompanied by increased domestic energy consumption. Vietnam’s General Statistics Office estimates that electricity demand will grow at recent annual growth rates of 10–12%, rising from 169.8 terawatthours (TWh) in 2015 to 615.2 TWh by 2030. In its 2013 country nuclear power profile, submitted to the International Atomic Energy Agency, Vietnam forecast a 2015 generation capacity of a little more than 40 gigawatts (GW), increasing to nearly 140 GW to meet projected demand in 2030.

Vietnam’s fuel mix for electricity includes:

Coal In 2014, annual coal consumption was 19.1 million tons (17.2 million tonnes), in a 21% increase over 2013. Coal consumption has increased in 2015, as unseasonably hot weather contributed to a decline in hydropower generation. Vietnam is still developing its coal-mining sector and must import relatively higher-priced coal. State-owned PetroVietnam (PV) seeks to buy 11 million tons (10 million tonnes) of coal per year starting in 2017 to supply Vietnam’s domestic power industry.

Natural gas Increased foreign investment during the past decade resulted in greater natural gas exploration, increasing Vietnam’s proved natural gas reserves. The country produces as much natural gas as the nation consumes, but PV expects a potential supply gap, with consumption outpacing supply. PV Gas, a subsidiary of PV, expects the Thi Vai and Son My liquefied natural gas (LNG) terminals will operate in 2017 and 2018. In 2014, PV Gas signed a sales and purchase agreement with Russia’s Gazprom. Under the agreement, PV Gas will receive 48 billion cubic feet of natural gas per year through the Thi Vai LNG terminal.

Nuclear The first nuclear reactors for power generation in Southeast Asia are planned to be built in Vietnam. In 2010, Russia agreed to build two 1,000-megawatt (MW) reactors at Nin Thuan 1. Japan followed in 2011 with an agreement to build Nin Thuan 2. Japan’s 2011 Fukushima nuclear accident delayed construction plans for both projects. Construction for the Nin Thuan 1 project is not expected until 2020.

Wind Vietnam is building the first offshore wind farm in Asia. Phase one (16 MW) of the Bac Lieu wind farm is operational, and phase two (83.2 MW) is expected to be complete in 2016. In March 2015, the United States Trade and Development Agency awarded a feasibility study grant for a potential phase three. Another project, the Tay Nguyen wind farm, broke ground in March 2015. The facility has a design capacity of 120 MW. The first phase (28 MW) is expected to begin operating in 2016.

Installing this generating capacity will require transmission and distribution (T&D) infrastructure. Electricity Vietnam, the state-owned utility, is pursuing the dual challenge of modernizing this infrastructure while also installing greater electric generating capacity. Securing international investment in planned generating capacity and infrastructure is also critical. The World Bank transmission efficiency project has committed US$500 million toward increasing T&D capacity and reliability in Vietnam.
