EVN engineers work on the national grid. The National Load Dispatch Center (A0) asks EVN for more infrastructure to launch a competitive retail electricity market in 2021. (Photo: VNA)According to a representative of the centre, wind and solar power plants havebeen put into operation on a large scale but data on their scale and generatingcapacity is not yet accurate.
The representative added that rooftop solar power, with a capacity of up to9,583 MWp, was affecting the load chart, making it tough to plan the powersystem operation as well as the market, especially due to the limitations ofthe transmission grid, particularly the 500kV / 220kV grid in the north.
The centre also said the operation processes of the hydroelectric plants with acapacity of more than 30 MW had shortcomings to fit with electricity marketregulations.
As the future infrastructure will convert the transaction cycle from 60 minutesto 30 minutes, while the core software has reached its limit, the centre hasasked EVN to soon install new tools.
Leaders of A0 also suggested the EVN consider offering supporting services forelectricity loading and dispatch to develop the market.
It also asked EVN to approve its plan for upgrading and expanding the existinginfrastructure systems such as SCADA / EMS to better collect metering data dueto the sudden development of renewable energy for the wholesale electricitymarket and the growing requirements for energy security.
At the same time, it asked EVN to equip the Electricity Market ManagementSystem (MMS) system for after 2022 to ensure the infrastructure for thewholesale/retail electricity market with renewable energy.
The centre’s representative said in 2021, it would set up better systems toimprove the economic efficiency of the electricity system and minimiseelectricity costs for the country, adding it would develop the informationtechnology infrastructure for the future for the wholesale electricity market.
The centre also planned to complete the project of upgrading the ITinfrastructure to serve the competitive wholesale electricity market of Vietnam(VWEM) in 2020-2022 as well as apply open-ended technical innovations andscientific research.
The centre said it would improve the quality of short-term and long-term loadforecasting for uncontrollable power sources including renewable energy,rooftop solar power and wind power sources.
With an increasingly large-scale power system and the development of renewableenergy sources to replace fossil fuels, the centre said it would proposesolutions to strengthen the legal framework for renewable energy sources.
The centre said it would research and install storage equipment to fit with theincrease in renewable energy sources to meet local operational requirements andstandards.
Regarding human resources, it would recruit new engineers and improve theexisting ones with more quality training to meet the requirements of awholesale electricity market.
According to the centre, there are 100 plants directly participating in theelectricity market with a total installed capacity of 27,526 MW, accounting for46.3 percent of total installed capacity of power plants controlled by thenational dispatching level. In 2020, four new factories joined the market witha total capacity of 1,837 MW. The total cost for those plants was 122 trillion VND(5.3 billion USD).
Last year, the centre prepared to operate the wholesale electricity marketincluding the calculation and announcement of market electricity price (CSMP),market capacity price (CCAN), total market price (CFMP), rate of electricitypurchase and cost of purchasing electricity from some factories of power corporations.
It also helped compile five processes regulating the operation of thecompetitive wholesale electricity market and reported to the EVN on theelectricity market operation in 2021-2030 in the EVN’s Power Plan VIII.
The ENV is eyeing the operation of a competitive retail electricity market in2021 after running a competitive wholesale market since 2019. The plans werespecified in 2013, with the marketplace set to be developed in three distinctparts – the power generation market, the wholesale market and the retailmarket./.
