Renewable Power Generation Costs in 2022
Executive Summary
In 2022, the International Renewable Energy Agency (IRENA) reported significant advancements in renewable energy costs, showcasing a pivotal shift towards sustainable energy systems. Key highlights include:
-
Competitiveness of Renewable Power: Despite challenges posed by COVID-19 supply chain disruptions, rising commodity prices, and rapid solar photovoltaic (PV) deployment, the global average cost of electricity from solar PV fell by 2%, and that of onshore wind dropped by 5%.
-
Electrification's Central Role: With the continued competitiveness of renewable energy, electrification emerges as a central pillar in the energy transition, offering opportunities for climate safety, enhanced energy security, and cost reduction.
-
Energy Security Benefits: The year underscored the importance of renewable energy for energy security, particularly in Europe, where existing renewable capacity installed since 2010 reduced electricity generation costs by USD 176 billion.
-
Decarbonization Pathway: Renewable energy costs continue to decline, making it increasingly attractive compared to fossil fuel alternatives. At least 86% of new utility-scale solar PV capacity and 87% of onshore wind capacity additions in 2022 had lower costs than new fossil fuel options.
Latest Cost Trends
Onshore Wind: With a focus on turbine characteristics, total installed costs, capacity factors, operation and maintenance expenses, and levelized cost of electricity, onshore wind demonstrates a robust cost reduction trend.
Solar Photovoltaics: Solar PV exhibits a similar pattern with decreasing costs, driven by technological advancements and economies of scale, impacting total installed costs, capacity factors, O&M expenses, and levelized cost of electricity.
Offshore Wind: Highlighting advancements in technology and infrastructure, offshore wind installations show significant progress in reducing costs, influenced by larger turbines, improved installation techniques, and optimized site-specific conditions.
Foreword
