  "description": "Vietnam operates one of Southeast Asia's fastest-growing electricity grids \u2014 demand has grown at 9.4% CAGR since 2010 and is projected to reach 535 TWh by 2030 (Power Development Plan 8 baseline). The country signed the Just Energy Transition Partnership (JETP) in December 2022, mobilizing $15.5B in public and private financing to peak power-sector emissions by 2030 and phase out coal entirely by 2040. The binding structural contradiction: Vietnam has 26 GW of coal capacity either operational or under active construction as of 2026 (14 GW operational, 12 GW in various construction stages), representing $28B in sunk costs financed primarily by Chinese, Japanese, and Korean development banks with 25-year Power Purchase Agreements (PPAs) that do not include climate termination provisions. EVN (Electricity of Vietnam, state monopoly) faces a triple constraint \u2014 it cannot pay for early coal retirement (debt covenants prohibit unilateral contract termination), it cannot build fast enough to replace coal with renewables (transmission backbone is 2\u20134 years behind demand growth), and it cannot raise electricity tariffs to fund the transition (tariffs are set by MOIT below cost-recovery for residential customers). The JETP's 2030 peak-emissions milestone requires 30\u201340 GW of new renewables operational by 2030, but Vietnam's renewable permitting process averaged 6.3 years per project from application to commercial operation as of 2024. EVN's grid absorption capacity in the Central and Southern regions is the hard constraint \u2014 9,400 MW of approved solar and wind projects are curtailed at rates of 20\u201340% due to insufficient 500 kV North\u2013South transmission capacity.",
