Summary of the Electricity 2025 Report by the International Energy Agency

Overview

The Electricity 2025 report highlights global electricity trends, driven by strong demand growth, particularly from emerging economies like China and India, due to electrification and industrial expansion. Supply is increasingly dominated by renewables, especially solar and wind, supported by nuclear growth in some regions. Key challenges include managing negative pricing, extreme weather events, and supply shortages in developing nations. The report emphasizes the need for policy actions, infrastructure investments, and market reforms to ensure reliable, affordable, and low-emissions electricity systems.

Key Findings

Global Electricity Demand

• Record Growth: Global electricity demand rose to its fastest pace in years, set to grow by 3.9% annually through 2025-2027.
• Drivers: Rapid electrification, rising cooling needs, expansion of data centers, and economic growth, especially in Asia-Pacific and Americas.
• Advanced Economies: Demand growth slowed but reversed in key regions like the U.S., with electrification of transport and heating driving increases.

Supply-Side Trends

• Renewable Dominance: Renewables will account for over 90% of new electricity generation through 2025-2027, led by solar PV and wind.
• Negative Pricing: Increased frequency of negative wholesale electricity prices signals a need for system flexibility.
• Nuclear Expansion: Reactor restarts in France, Japan, and China are boosting nuclear output, supporting clean energy transitions.

Emissions and Decarbonization

• Global CO₂ emissions from electricity generation peaked in 2024 but are expected to stabilize due to renewable growth.
• China and India are phasing out coal, but coal remains a significant source globally.

Policy and Market Developments

• Energy Transition: Policies like carbon pricing, auctions for green hydrogen, and grid reforms aim to accelerate decarbonization.
• Negative Pricing Concerns: Regulatory frameworks and market designs must better incentivize flexibility from storage, demand-response, and demand-side resources.

Reliability and Extreme Weather Risks

• Extreme weather has caused widespread power disruptions, highlighting the need for better resource adequacy assessments and investments in grid resilience, storage, and interconnections.

Regional Highlights

• Asia-Pacific: China and India lead demand growth, with renewables expanding rapidly.
• Americas: U.S. demand rebounds, driven by data centers and manufacturing. Reliance on gas for flexibility.
• Europe: Renewables dominance increasing, with nuclear providing stability. Polarization in policy debates.

Recommendations

• Strengthen grid flexibility through demand-response and storage.
• Enhance weather risk integration into resource adequacy studies.
• Accelerate low-emissions technologies (hydrogen, nuclear) to ensure supply security.
• Reform electricity markets to properly value system flexibility amid high VRE penetration and decarbonization goals.
