Summary of IEA's "Electricity 2024" Analysis and Forecast to 2026

Introduction

• The IEA's Electricity 2024 report examines global electricity trends, demand, supply, emissions, prices, and reliability up to 2026, emphasizing the role of electricity in decarbonization efforts and its central function in modern economies.
• Electricity demand rose modestly in 2023 but is expected to grow faster through 2026, driven by electrification, economic recovery, and data centers, while supply expansion is focusing on renewables and nuclear to meet increases.

Electricity Demand

• Global electricity demand is projected to increase at an average annual rate of 3.4% from 2024 to 2026, with most growth occurring in emerging economies.
  • China leads demand growth but at a decelerating pace (5.1% in 2024).
  • India and Southeast Asia are major growth drivers, while Africa's per capita consumption remains stagnant.
• Key drivers include the ongoing electrification of residential and transport sectors, energy-intensive industries, and rapid expansion of data centers.
• Despite post-pandemic recovery, advanced economies experienced declines in 2023, with demand returning to growth by 2024.

Supply

• Renewables are set to overtake coal as the largest source of global electricity supply by 2025, driven by cheap solar PV and policy support.
• Nuclear power generation reached new record highs in 2024, with continued growth expected.
• Supply chain issues for gas turbines and critical minerals pose risks, but investments in grid modernization and modular reactors (SMRs) aim to enhance stability.
• Renewables deployment is accelerating, with significant contributions from solar and wind.

Emissions

• Global CO2 emissions from electricity generation are forecast to decline for the first time in decades, entering a structural downward trend.
  • Coal's share is projected to fall to around 39% by 2026.
  • Renewables and nuclear are driving this reduction, with CO2 intensity expected to drop 4% annually by 2024-2026.

Prices

• Wholesale electricity prices have moderated since 2022 but remain above pre-COVID levels in many regions.
• Regulations and pricing mechanisms aim to improve affordability and reduce price volatility, with initiatives like the EU's CBAM affecting trade.
• High energy costs impact industries, particularly in Europe, and can threaten competitiveness, with compensations and tax reforms being considered.

Reliability

• Electricity security issues are intensifying due to increased weather dependency from renewables, leading to measures like inertia markets and fast frequency response services.
• Events like extreme weather and grid outages highlight vulnerabilities, especially in emerging economies.
• Investments in grid resilience, battery storage, and distributed systems are essential to manage future challenges.

Key Notable Points

• Data centers could double global electricity demand by 2026, with digitalization being a major factor.
• Nuclear power is regaining interest; for example, China and Russia are leading reactor construction, while Europe explores SMR technology to enhance flexibility.
• Decarbonization efforts include stricter regulations on emissions and incentives for clean energy transitions, aiming to keep global warming below 1.5°C.
• Regional disparities persist, with advanced economies leading in reliability measures, while emerging ones face affordability and access issues.

In essence, the electricity sector is advancing rapidly toward decarbonization, with renewables and nuclear playing pivotal roles, though challenges like grid stability, fossil fuel dependencies, and global economic disparities remain critical barriers.
