Electricity Market Report Summary (January 2022)

Core Content

The IEA Electricity Market Report for January 2022 provides a comprehensive overview of global electricity demand, supply, emissions, and the impact of economic recovery and energy price dynamics from 2021 to 2024.

Main Points

Global Electricity Demand Growth

• 2021 Growth: After a small drop in 2020, global electricity demand increased by 6% in 2021, the largest annual increase since 2010.
• 2022–2024 Forecast: Annual demand growth is expected to slow to 2.7% over the next three years.
• Regional Contributions:
  • China: Accounted for around 50% of global demand growth.
  • India: Contributed 12%.
  • Europe: 7%.
  • United States: 4%.

Supply and Generation Mix

• Coal-fired generation reached an all-time high in 2021, growing by 9% and meeting more than half of the additional demand.
• Renewables grew by 6% in 2021, despite unfavourable weather conditions.
• Gas-fired generation increased by 2% in 2021 but is expected to grow at 1% annually from 2022 to 2024.
• Nuclear generation increased by 3.5% in 2021, nearly reaching 2019 levels.
• Renewables Dominance: From 2022 to 2024, renewables are expected to grow by 8% annually, meeting 90% of net demand growth. By 2024, renewables could account for 32% of global electricity supply, up from 28% in 2021.
• Low-Carbon Generation: Expected to increase to 42% of total generation by 2024, up from 38% in 2021.
• Fossil Fuels: Will still account for 58% of total electricity generation by 2024, down from 62% in 2021.

Emissions Trends

• 2021 Emissions: Rose by 7%, reaching a new all-time high, with coal being the main driver.
• 2022–2024 Outlook: Emissions are expected to plateau due to slowing demand and increasing low-carbon generation.
• CO₂ Emissions: Projected to reach over 13 Gt by 2024.
• Emissions Intensity: Increased by 1% in 2021, the first rise since 2011. It is expected to decline by 2% annually from 2022 to 2024.

Economic Recovery Impact

• Global GDP Growth: Estimated to be 5.9% in 2021, 4.9% in 2022, 3.6% in 2023, and 3.4% in 2024.
• China and India: Expected to grow by 8% and 9.5% in 2021, respectively, and maintain growth above 5% and 6% in the following years.
• Energy Price Uncertainty: High gas and coal prices in 2021 led to increased thermal generation costs and fuel switching from gas to coal in the U.S. and Europe.
• Macroeconomic Impact: High energy prices could reduce global GDP growth by 0.3% in 2021 and 0.5% in 2022.

Fossil Fuel Price Trends

• Gas and Coal Prices: Surged to multi-year highs in the second half of 2021 due to tight supply and high demand.
• U.S. Natural Gas: Henry Hub prices more than doubled compared to 2020, averaging USD 4.6/MBtu.
• Coal Prices: Remained more stable, with coal-fired generation becoming more cost-competitive than gas in some markets.
• 2022–2024 Outlook: Gas prices are expected to decrease by 12% (Henry Hub), and coal prices by 10%, improving cost competitiveness.

Key Information

Supply Constraints and Power Shortages

• China and India: Both faced significant electricity supply shortages in late 2021 due to rapid demand growth and coal supply interruptions.
• Impact on Industrial Sector: Power cuts affected industrial demand, with some provinces in China and states in India experiencing up to 10–12 hours of load shedding.
• Coal Supply Issues:
  • China: Mine closures and rainy seasons affected domestic coal production.
  • India: Coal stocks at power plants reached critical levels (less than 5–9 days of supply), leading to severe shortages in the Northern Region (rated Category 4 on ESES).

Policy and Market Responses

• China: Reopened previously closed coal mines, increased production targets, and removed price caps for energy-intensive consumers.
• India: Prioritised coal supply for power plants, introduced guidelines for efficient plant operation, and implemented measures to blend local and imported coal.

Outlook

• Renewables: Will dominate supply growth, with coal and gas expected to stagnate.
• Decarbonisation Challenges: Current policies are insufficient to meet the IEA’s Net Zero Emissions by 2050 scenario, highlighting the need for greater energy efficiency and low-carbon supply.

Regional Perspective

• Asia-Pacific: Expected to be the main driver of global electricity demand and supply growth.
• Europe and U.S.: Will see slower growth, with energy efficiency measures countering increased electrification.
• Middle East and Africa: Experiencing varied economic recoveries and inflationary pressures.

Conclusion

The report highlights the resilience of global electricity markets in 2021 despite challenges, but also underscores the need for urgent policy changes to meet climate goals. While renewables are expected to grow rapidly, the continued reliance on fossil fuels remains a key obstacle to decarbonisation.
