Decision 203/QD-EVN, issued on October 27, 2020, is a foundational regulatory document used by the Vietnam Electricity (EVN) Group to standardize the cost estimation for power grid maintenance and repair.

Regulatory Standards: Performance metrics that power units must meet during operations. Decision 203/QD-EVN , issued on October 27, 2020

3.1 Grid Connection Requirements

• Voltage Levels: The decision specifies the standard voltage levels at which solar plants must connect (typically 110kV or 220kV for large-scale projects).
• Capacity Assessment: It mandates calculations regarding the "hosting capacity" of existing substations. A project can only be approved if the local substation has spare capacity.
• Reactive Power: Investors are required to install reactive power compensation devices (capacitor banks) to maintain power factor standards, ensuring voltage stability at the connection point.

When combined with other regulations like Circular 36/2022/TT-BCT (for new installations) and Circular 12/2021/TT-BXD, Decision 203 helps calculate: Total repair costs for substations and transmission lines. Voltage Levels: The decision specifies the standard voltage

For example, the document sets a threshold for commercial vs. technical losses, forcing local power companies to upgrade aging infrastructure if they exceed the norm.

3. If you cannot find it

Because QĐ-EVN documents are internal corporate decisions, they are not always publicly released. In that case:

Labor costs for specialized tasks like installing wires after meters.
