Hanoi (VNA) - Low power demand coupled with oversupply ofelectricity at times have forced authorities to cut the capacity of renewableenergy plants in order to avoid overwhelming the national grid, according tothe Ministry of Industry and Trade (MoIT).
A large amount of investments from social resources has been poured into developingrenewable energy, particularly solar energy, over previous years in Vietnam, according to the ministry.
However, a boom in high-capacity renewable energy projects, mainly incentral and southern Vietnam, has overloaded inter-regional transmission linesand caused oversupply at times, the ministry said in Document No 1226/BCT-DTDL sentto the National Assembly’s committees for Science, Technology and Environment, and Economic Affairs and the Office of the Government explaining its stance on the power capacitycut.
Additionally, domestic demand for power has fallen below normal levelsdue to the impact of COVID-19, which led to an oversupply of electricity duringoff-peak times such as holidays, weekends, and at noon, the ministry said.
According to the ministry, this is a very dangerous situation that adversely affects the safeoperation of the national grid. Though the National Load DispatchCentre (A0) has reduced the output of traditional energy to the minimum, theoversupply remains, so the centre had to make another cut to renewable energycapacity to prevent the electricity system from collapsing.
The ministry has ordered Vietnam Electricity (EVN) and A0 to calculate therequired reduction of capacity at all renewable power plants in a transparentand fair manner, regardless of who their investors are.
The ministry added that it has received government approval onthe supplement of various power transmission line projects into planning while urging EVN to fast-track the progressof existing projects to raise the capacity of the national electricity network./.
