Summary of IEA's "Electricity 2025" Report

The International Energy Agency's (IEA) "Electricity 2025" report highlights a global transition toward a "new Age of Electricity," driven by robust demand growth, electrification, and the rapid expansion of renewable energy. Electricity consumption is projected to increase at an average annual rate of 3.9% through 2027, reaching a global total of 34,566 TWh. Renewables (including solar, wind, and hydropower) are expected to account for over 50% of new electricity generation by 2027, surpassing coal's contribution.

Key Highlights:

1. Global Demand Growth: Driven by emerging electrification (buildings, transport, industry), data centers, and economic expansion. Advanced economies and China lead demand growth, while Africa faces supply capacity constraints despite rising needs.

2. Supply and Emissions: Renewables dominate supply growth (40% of additional generation from solar PV alone), limiting CO₂ emissions. Global CO₂ intensity fell to 400 g CO₂/kWh in 2027 from 445 g CO₂/kWh in 2024, with renewables playing a pivotal role.

3. Regional Focus:

   • China: Electricity demand grows at 6-7% annually, fueled by industrial demand (EVs, solar panels) and cooling needs. Solar PV supply expands rapidly, while coal's share declines to 50% by 2027.
   • Indonesia: Rapid coal-to-gas switching and renewable expansion aim to meet 50% renewable share by 2030.
   • Southeast Asia: Strong demand growth, supported by gas infrastructure and solar deployment.
   • Europe: Renewables surge to 56% of generation by 2027, phasing out coal by 2030 in key countries.
   • Africa: Electrification challenges persist, with distributed solar addressing rural gaps, but grid infrastructure remains a bottleneck.

4. Grid and Market Challenges: Rising negative prices in markets like Australia and Europe necessitate flexibility investments. Grid tariffs are expected to increase, requiring regulatory reforms to manage costs and enhance resilience.

5. System Integration: Weather-dependent generation requires storage and interconnectors (e.g., Morocco-Tanzania projects). Policies like the EU’s Green Deal and national auctions support renewables and carbon capture.

Forward Outlook:

Coal's role diminishes, while renewables and nuclear power scale up. Extreme weather events and geopolitical risks add complexity, underscoring the need for flexible resources and international energy cooperation.
