02. Key features of VWEM 2019
04. VWEM implementation in Q3/2019 & Q4/2019
03. Operational result of Q1/2019 & Q2/2019
01. Preparation background
National Load Dispatch Center 4
Legal framework
Decision 63/2013/QĐ-TTg: Decision on the roadmap, conditions and sector structure for
establishment and development of power market grades in Vietnam
Decision 8266/QĐ-BCT: Approval of the detailed design of Vietnam's competitive
wholesale electricity market
Decision No. 3038 / QD-BCT dated August 10, 2018 of the Minister of Industry and Trade
on the plan to operate the wholesale electricity market in 2019.

Regulatory framework
Cost regulation (cross-subsidizing) between PCs
According to Decision 8266/QĐ-BCT: cost regulation (cross-subsidizing) between PCs through
a balance account or equivalent mechanism. This appeared to be new mechanism that needs
to be researched carefully.
In 2019: the cost regulation between the PCs will continue to be implemented through the
Bulk Supply Tariff mechanism of EVN.
Contract allocation
According to Decision 8266/QĐ-BCT: allocate all existing contracts (CfD) between EVN and
Generation company to PCs.
In 2019, only a number of contracts will be allocated to PCs due to the absence of a regulatory
mechanism between the PCs through the Balance Account.
In 2019, EVN will continue to perform the spot electricity payment function until NLDC is
accounted independently and the mechanism of separating payment of CFD contracts and
spot market is established.

VWEM 2019 objectives
Implement the operation of VWEM 2019 under Decision 8266/QD-BCT subjects to the
constraints on apparent conditions;
Improve mechanisms to participate in electricity market for generation company;
Evaluate the mechanisms of VWEM 2019; completing the legal framework, IT
infrastructure to gradually implement VWEM under Decision 8266/QD-BCT.

The operating mechanism
Generators: participate in electricity market similar to the on-going generation market;
PCs:
Purchase a part of the electricity consumption (off-take from the grid) on the electricity
market. The rest of the electricity consumption is purchased from EVN under the mechanism
of BST;
Continue to implement the contract allocation of Phu My 1 and Phu My 4 power plants with
the same mechanism as 2018;
Directly sign PPAs with 04 new power plants (go into operation in 2018 and 2019).
National Load Dispatch Center 9
Signing contracts with new power plants participating in VWEM
In 2019, there are expected to be 04 new power plants participating in the power market
to sign contracts directly with the PCs: Thai Binh 1, Vinh Tan 4, Duyen Hai 3 MR, Vinh Tan 4
MR (From the first day of the month following the month of COD).
Principles of negotiation and signing contract:
EVN negotiates with 05 PCs as regulated in Circular 56/2014/TT-BCT and Circular 13/2017/TT-
BCT of the Ministry of Industry and Trade and other Circulars (if any).
Each new power plant signs 05 contracts with 05 PCs. The contract quantity (Qc) of the power
plant with a PC is directly proportional to the power consumption (load) of the PC. The
contract price is the negotiated price agreed between 06 parties.

Operational results - System
System Operation difficulty
The rate of load growth is still high (approximately 10% annually)
The installation of plants and grid is slow and inconsistent. It does not meet proposed
schedule causing overload and electricity shortage on the power system.
Uncertainty of hydro power plant with many constraints in operation and irrigation
Limited fuel for electricity generation (coal, gas…)

Renewable Energy
By the end of June 2019, the total number of renewable power plants in operation was 91
(including 82 solar power plants, 06 wind power plants and some other biomass) with a
total installed capacity of 4900 MW.

Operating results
The capability of PCs and market participants in the VWEM has been significantly
improved
CfD contracts, market settlement mechanism;
Improve knowledge of electrical system operation and skills through training and practical
operations.
Demand forecasting ability has been developed
The load forecast is noticeably improved, leaving only a few unstable moments due to the
large proportion of the residential load, affected by unpredictable factors such as weather,
especially in abnormal weather periods.
Complete the collection, publication and checking of metered data: with over 99% of
accurate data collected by NLDC
Information technology infrastructure operates stably, meeting operation requirements
