Siemens to help build Vietnam’s largest solar plant
July 29 17:36 2018

Siemens Vietnam has won the contract to supply systems to the Trung Nam Group and put the country’s largest solar farm into operation.  The 204 megawatts peak (MWp) capacity farm is the first solar project for Siemens in Southeast Asia.

The project, in the southern province of Ninh Thuan, will be developed by mid-2019 and will deliver up to 425 gigawatt hours (GWh) per year of energy, enough to supply 200,000 households with electricity and save 250,000 tons of carbon dioxide annually.  

Technically, the project constitutes an “Electrical Balance of Plant” (eBoP) solution, and involves a number of Siemens units, headed by its Medium Voltage and Systems division. The eBoP solution includes all the electrical engineering components needed to equip a photovoltaic plant.  Project deliverables include inverters, power and distribution transformers, gas-insulated medium-voltage switchgear, circuit breakers, and monitoring and control systems. 

Solar panels will generate a combined direct current (DC) voltage of 1,500 volts (V). Inverters will convert the DC to 660 V alternating current (AC), and transformers will first step this up to 33 kilovolts (kV) and finally to 220 kV.  This will then be fed into the high-voltage grid and the power distributed around the country. The components needed up to the 33kV level are designed as a “plug-and-play MV station”, and can therefore be installed as a standalone unit without major construction cost.

Pham Thai Lai, President & CEO of Siemens Vietnam said: “With the capacity of 204MW, the Trung Nam Solar Power Plant is the largest single plant of its kind in Vietnam, thus making Trung Nam a true pioneer in solar energy in Vietnam. We are very pleased to partner with Trung Nam Group for this truly remarkable benchmark project thus creating clean and environmentally friendly energy for Vietnam.” 

Nguyen Tam Tien, the General Director of Trung Nam Group said of the project that, “Vietnam’s need for energy is rapidly growing. To cover this demand, we must increase the share of renewables, among other things. The government is aiming at developing 18 gigawatts of generating capacity by 2030. Siemens is supporting us with our solar project so we can reach the government targets for developing renewable energy in Vietnam.”

Vietnam’s government is allowing a variety of renewable energy projects that focus on solar and wind power to proceed across the country. It has been analyzing its current mix of energy producers to change the current balance, which favors coal plants, and instead increases clean renewable projects across he country.
