Long An Province Power Development Plan for phase 2011 – 2015 with considerations to 2020 has the following main criteria:
I. Power load
The power load is calculated to meet the sufficient power demand for socio-economic development of Long An province with the GDP growth rate in Phase 2011 – 2015 of 14.0%/year; GDP growth rate in phase 2016-2020 of 13.3%/year.
- In 2015: It is estimated that the maximum capacity is Pmax= 772,3MW, the commercial power capacity is 4507.9 million kWh. The average growth rate of the commercial power in phase 2011-2015 is 20.2%/year.
- In 2020: It is estimated that the maximum power is Pmax=1528.0MW; the commercial power is 9,428.8 million kWh. The average growth rate of the commercial power in phase 2016 - 2020 is 15.9%/year.
