Siemens has been awarded a contract to both supply equipment to, and commission a, 258 MW solar PV power plant in Vietnam for the Trung Nam Group. It is the first PV project for Siemens in Southeast Asia, said the Munich Group in a statement released.
The equipment order includes inverters, power and distribution transformers, gas-insulated medium voltage switchgear, circuit breakers and a monitoring and control system.
While they would not divulge the extact amount, a spokesperson for Siemens told pv magazine the contract is in the double digit million range (€). Deliveries are set to commence this October, they added.
The PV park is expected to be built by the middle of next year, in the southern province of Ninh Tuan. It will be fitted out with solar modules with a combined DC voltage of 1500 volts.
The inverters, meanwhile, will convert the DC power into 660 volts AC, after which the transformers will boost this firstly to 33 kV and then, finally, 220 kV. The necessary components up to the 33 kV level have been designed as a “Plug & Play MV station” and can, therefore, be installed as a single unit, without great effort on the construction side, said Siemens.
The generated solar power will be fed into the high-voltage grid and distributed throughout Vietnam. Up to 425 GWh a year are expected to be produced, when the project is complete.
This year has seen announcements for at least six large-scale ground mounted solar PV projects in Vietnam, including from Grimm Power and Xuan Cau, which began construction on two solar PV plants totaling 300 MW in the southern province of Tay Ninh last month; Sunseap International, which started construction on a 168 MW project in Ninh Thuan Province in the south of Vietnam; and Sterling & Wilson’s plans to install 300 MW by next year, across the country.
JA Solar, meanwhile, announced last week that it had secured a long-term buyer credit loan facility worth US$68.4 million for the procurement of equipment for its 1.5 GW wafer facility in Vietnam; and Ecoprogetti said in February that it had finalized an order for a 250 MW PV production line in the country. The glass-backsheet line was expected to be installed by June 2018.
