Summary of IEA Electricity 2024 Report (Analysis and Forecast to 2026)

Core Content

The International Energy Agency (IEA) Electricity 2024 report provides a comprehensive analysis of global electricity demand, supply, emissions, and prices through 2026, emphasizing the ongoing energy transition and the challenges it presents.

Main Points and Key Information

Global Electricity Demand

• 2023 Growth: Global electricity demand rose by 2.2%, slightly lower than the 2.4% growth in 2022.
• 2024–2026 Forecast: Demand is expected to grow at a faster rate, averaging 3.4% annually.
• Drivers of Growth:
  • Electrification of residential and transport sectors.
  • Expansion of the data centre sector, which could double electricity consumption by 2026.
• Data Centre Impact:
  • Consumed 460 TWh in 2022 and is projected to reach over 1000 TWh by 2026.
  • This demand is equivalent to that of Japan.
• Regional Contributions:
  • China has the largest increase in demand, while India has the fastest growth rate.
  • Southeast Asia also shows strong growth, with an average of 5% per year.
• Per Capita Consumption:
  • China's per capita electricity use exceeded that of the EU in 2022.
  • Africa's per capita use remains stagnant, with a projected recovery to 2010–15 levels by 2026.

EU Electricity Demand

• Decline in 2023: The EU saw a 3.2% year-on-year decline, the second consecutive year of reduced demand.
• Industrial Sector Impact: Weak industrial demand was the main cause of the decline, despite falling energy prices.
• Recovery Outlook: EU demand is not expected to return to 2021 levels until 2026.
• Competitiveness Concerns: EU energy-intensive industries face higher electricity costs than those in the US and China.
• Growth Drivers:
  • Electrification of transport and heating.
  • Data centres are expected to account for over one-third of the additional demand.

Electricity Supply

• Clean Energy Growth: Low-emission sources (renewables and nuclear) are expected to meet all additional demand through 2026.
• Renewables Expansion:
  • Renewables will account for 37% of global electricity generation by 2026.
  • Solar PV is the main driver of renewable growth.
• Coal Trends:
  • Global coal-fired generation is forecast to decline by 1.7% annually through 2026.
  • China's coal generation is expected to experience a slow structural decline, influenced by renewable expansion and economic slowdown.
• Nuclear Power:
  • Nuclear generation is projected to reach a new record high by 2025.
  • Over half of new reactors during the outlook period will be in China and India.
  • Asia is set to surpass North America in nuclear capacity by 2026.

CO₂ Emissions

• Structural Decline: Emissions from electricity generation are entering a structural decline.
• 2024 Forecast: CO₂ emissions are expected to fall by over 2% in 2024 after a 1% increase in 2023.
• Emission Intensity:
  • Global CO₂ intensity is projected to fall at twice the pre-pandemic rate.
  • EU leads with a 13% annual improvement, followed by China (6%) and US (5%).
• Decarbonisation Targets: Electrification of transport, heating, and industry will lead to substantial emissions savings.

Electricity Prices

• Wholesale Prices: Prices fell in 2023 from record highs in 2022, but remain above pre-pandemic levels in many regions.
• EU Prices: Fell by over 50% in 2023 but are still double 2019 levels.
• US and China Prices: Remain only 15% and 20% higher than 2019, respectively.
• Data Centre Costs: The data centre sector is a major contributor to rising electricity consumption and costs.

Reliability and Security

• Weather Impacts:
  • Droughts and early snowmelts reduced global hydropower output.
  • Hydropower capacity factor fell to below 40%, the lowest in at least 30 years.
• Power Outages:
  • Extreme weather events caused significant outages in the US and India.
  • Most outages were observed in emerging economies, such as Pakistan, Kenya, and Nigeria.
• System Stability:
  • Measures to ensure system inertia and frequency stability are becoming more common.
  • Markets for fast frequency response and battery storage are being developed to support grid stability.

Conclusion

The report highlights the acceleration of the energy transition, with renewables and nuclear power leading the shift away from fossil fuels. While emerging economies are the primary drivers of electricity demand growth, advanced economies and the EU face challenges in recovering from the effects of the energy crisis and maintaining competitiveness. The data centre sector is a growing concern due to its significant impact on electricity consumption. Ensuring grid reliability, investing in infrastructure, and improving data transparency will be critical to supporting the global shift towards cleaner, more resilient electricity systems.
