Electricity Market Report 2023 Summary

Core Content

The International Energy Agency (IEA)'s Electricity Market Report 2023 provides a comprehensive analysis of global electricity demand, supply, emissions, and market trends up to 2025. It highlights the ongoing impact of the global energy crisis, the role of renewable energy in the transition to net-zero emissions, and the challenges of affordability and supply security in different regions.

Main Views and Key Information

Global Electricity Demand Trends

• 2022 Growth: Global electricity demand grew by nearly 2%, slightly slower than the 2.4% average from 2015-2019, but remained resilient amid the energy crisis.
• 2023-2025 Outlook: Demand is expected to grow at a faster pace, 3% per year, driven by Asia, particularly China, India, and Southeast Asia.
• China's Role: China will account for over 70% of the global demand growth, with an estimated 5.2% annual increase from 2023-2025.
• EU and US Trends: The EU saw a 3.5% decline in electricity consumption in 2022, while the US increased by 2.6%. The EU is projected to grow by 1.4% annually from 2023-2025.
• India's Growth: India's demand rose by 8.4% in 2022 due to economic recovery and extreme weather conditions.

Supply Mix and Emissions

• Renewables and Nuclear: Renewables and nuclear energy will dominate the growth in electricity supply, covering over 90% of additional demand by 2025.
• CO₂ Emissions: Global power generation emissions grew by 1.3% in 2022, the slowest increase since 2021, but still reached a record high. Emissions are expected to plateau through 2025 as renewables grow.
• EU Emissions: The EU saw a 4.5% increase in CO₂ emissions in 2022, the highest since the 1970s oil crises, due to increased coal usage. Emissions are expected to decline by 10% annually through 2025 as coal and gas generation fall.

Regional Highlights

• Asia Pacific:
  • By 2025, Asia will account for half of global electricity consumption, and China will consume one-third.
  • Nuclear Power Growth: China, India, Japan, and Korea will account for over half of the global nuclear generation growth. China leads in absolute terms with a +58 TWh increase, while India has the highest percentage growth at +81%.
• Europe:
  • Gas-fired generation increased by 2% in 2022 due to coal shortages and higher gas prices.
  • France became a net importer and the UK a net exporter for the first time in decades.
  • Nuclear and hydro output declined due to maintenance and drought, forcing reliance on gas.
  • Supply Security: Countries increased reserve capacities and extended decommissioned plants to ensure stability.
• Americas:
  • Coal and gas generation are expected to decline, with Asia Pacific offsetting these reductions.
• Middle East:
  • Gas-fired generation is expected to grow significantly, helping balance global supply trends.
• Africa:
  • Electricity demand grew by 1.5% in 2022, but is projected to increase by 4.1% annually from 2023-2025 due to post-crisis recovery.

Market Challenges and Responses

• High Prices: Electricity prices remained high in many regions, especially in the EU, where they were over twice as high in 2022 compared to 2021.
• Policy Responses:
  • The EU introduced the REPowerEU plan to boost clean energy.
  • Countries implemented measures such as price caps, subsidies, and tax reductions to support consumers.
• Affordability Issues:
  • Emerging and developing economies face affordability challenges due to high energy commodity prices.
  • LNG prices in particular caused issues for South Asian countries, leading to blackouts and electricity rationing.

Climate and Weather Impacts

• Weather-Dependent Demand: Extreme weather events, such as droughts, heatwaves, and winter storms, increased the weather dependency of electricity demand.
• Need for Flexibility: Power systems must become more flexible and resilient to handle increased variability in demand and supply.

Conclusion

The report underscores the complex interplay between economic recovery, climate change, and energy security in shaping the global electricity market. While renewables and nuclear are set to drive supply growth, fossil fuels still play a significant role, particularly in China, EU, and Middle East. The EU faces a temporary increase in emissions due to coal usage, but is expected to decarbonize over the next few years. Asia is becoming the main driver of global electricity demand, and electricity affordability remains a pressing issue for emerging economies. The IEA highlights the need for policy coherence, investment in grids, and market reforms to ensure a stable and sustainable electricity future.
