Vietnam's efforts to boost solar energy in 2018 by offering 9 cents per kilowatt hour to owners of solar farms is leading to unexpected surge in solar energy. Instead of the 850 MW of solar energy the production increased to 5 gigawatts by 2019. Investments had be done in 2 years for the offer by the state owned electricity company and electricity purchases would depend on daily needs. The huge increase has brightened the prospects for solar energy in this part of Asia. 
 

Most of the solar energy comes from the southern part of Vietnam and the government is expanding the capacity of the power grid to handle the solar energy production. Vietnam is growing at 5-7% a year for two decades and power capacity is expected to double by 2030. The share of coal in the enrgy mix planned is 43%. The unexpected surge in solar energy production means the 10% fo solar energy in the energy mix was achieved ten years ahead of the schedule. This means fewer coal plants will be needed.

In five years solar energy is expected to become cheaper to produce than energy from coal, according to energy consultancy Wood Mackenzie. Coal plants are also meeting public resistance, and regulatory hurdles. Coal plants take ten years to become operation. Solar energy projects can be completed in 2 years. This means solar can take a much larger share of energy production in the future .
