Circular 64/2026/TT-BCT sets requirements for energy planning, reporting, management models and audits, Vietnam’s Government News reports. It covers major energy users and relevant budget-funded bodies consuming at least 100,000 kWh of electricity annually. Agencies operating in defense and security are excluded from its scope. Reporting uses the national dataenergy.vn system. The circular takes effect on November 20, 2026, so publication of the news does not bring that effective date forward.
