Summary of Achieving a Net Zero Electricity Sector in Viet Nam

Core Content

This report, published by the International Energy Agency (IEA), explores pathways for achieving a net zero electricity sector in Viet Nam by 2050, building on the country's Power Development Plan 8 (PDP8) and its commitments under the Just Energy Transition Partnership (JETP). It provides an analysis of electricity demand, supply, emissions, investments, and the role of system flexibility and security in transitioning to a low-carbon power sector.

Main Viewpoints

• Viet Nam's Electricity Growth:

  • Electricity demand has surged eightfold since 2002, reaching over 240 TWh in 2022.
  • Industry is the largest consumer of electricity, accounting for over 50% of demand, followed by commercial and residential sectors.
  • Coal has been the dominant electricity source, contributing 41% of generation in 2022, while solar PV and hydro also play significant roles.

• PDP8 as a Blueprint:

  • PDP8 outlines a comprehensive transformation of the electricity sector, aiming for a doubling of electricity demand by 2030 and a fivefold increase by 2050.
  • It sets a pathway for emissions reduction, targeting 204 Mt in 2030 and 170 Mt by 2050 if JETP commitments are fully met.
  • Coal-fired capacity is expected to peak at 30 GW by 2030 and be phased out by 2050, with some plants converted to ammonia or biomass.

• Renewables and Decarbonisation:

  • Renewable energy expansion is central to achieving net zero, with solar PV and wind leading the transition.
  • By 2050, solar PV is projected to reach 170–190 GW, and onshore wind is expected to grow from 4 GW to 60–80 GW.
  • Offshore wind is also planned to expand significantly, though the report suggests that hydrogen and ammonia may not be needed in such large volumes as initially envisioned.

• Energy Efficiency:

  • Energy efficiency measures can reduce electricity demand growth by up to 30% by 2050.
  • Key efficiency opportunities lie in industry (high-efficiency motors) and buildings (air conditioning, lighting, and electric cooking).
  • Energy efficiency can lower consumer bills but may increase the cost per unit of electricity produced.

• System Flexibility and Security:

  • Maintaining grid reliability and security is critical, especially with the rising share of variable renewables.
  • The report highlights the need for grid modernisation, demand response, and storage technologies (like batteries) to ensure system flexibility.
  • Hydropower is also essential for seasonal flexibility, though its role is expected to decline in favor of other sources.

• Investments and Affordability:

  • Power sector investments are projected to rise significantly, from less than USD 10 billion annually to at least USD 25 billion by 2030, peaking at USD 60 billion in the 2040s.
  • The NZE Scenario suggests that with relatively low additional investment, net zero can be achieved earlier than 2050.
  • Affordability remains strong, with average electricity costs per unit expected to stay below USD 100/MWh due to falling fuel expenditures and increasing renewable shares.

Key Information

• Emissions Trends:

  • CO₂ emissions in the power sector peak at 250 Mt in 2030 under the PDP8 Scenario.
  • In the PDP8+EE and NZE Scenarios, emissions fall to below 170 Mt by 2030, aligning with JETP targets.

• Challenges:

  • The high share of coal in the electricity mix (41% in 2022) presents a challenge for decarbonisation, as many plants are still in operation and new ones are under construction.
  • Grid bottlenecks and the lack of an alternative pricing mechanism have hindered the expansion of renewables, particularly solar PV.
  • The transition to hydrogen and ammonia faces challenges, including the high cost of fuels and potential increases in nitrous oxide emissions.

• Policy and International Cooperation:

  • The PDP8 is a key policy document that aligns with international commitments, including the JETP.
  • The JETP, signed in 2022, aims to support Viet Nam's transition through financial and technical assistance.
  • Regulatory reforms and international cooperation are crucial for attracting private investment in clean energy.

• Scenarios and Outcomes:

  • PDP8 Scenario: A baseline scenario with coal peaking in the mid-2020s, renewables growing to 15% of generation by 2022.
  • PDP8+EE Scenario: Incorporates energy efficiency measures, reducing demand growth and emissions.
  • PDP8+EE+LH Scenario: Combines energy efficiency and coal-to-gas switching, leading to significant emissions reductions.
  • NZE Scenario: A more ambitious path aiming for net zero by 2050, with a strong focus on renewables and energy efficiency.

• Supporting Measures:

  • The decree on direct power purchase agreements (No. 80/2024/ND-CP) is expected to accelerate renewable energy deployment.
  • Nuclear power could complement renewables, especially with new reactor designs and cost reductions.

Conclusion

The report outlines a clear roadmap for Viet Nam to achieve a net zero electricity sector by 2050, emphasizing the need for rapid renewable deployment, energy efficiency, and grid modernisation. It also highlights the importance of international support and regulatory reforms in enabling the transition. While the path to net zero is challenging, the IEA analysis suggests that it is achievable with the right policies and investments.
