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

Francesco La Camera, Director-General of IRENA, underscores the importance of renewable energy in addressing climate change, emphasizing the necessity for accelerated action. He notes that the competitiveness of renewable energy is not just about cost reduction but also about enhancing energy security and driving industrial development.

Conclusion

The global trend in renewable power generation costs indicates a strong move towards sustainability, with continued innovation and policy support expected to drive further reductions. The competitiveness of renewable energy technologies offers a compelling pathway towards achieving climate targets and securing a sustainable energy future.

The growing competitivenessof renewable power continues toprovide the most compelling pathwayto the decarbonisation of the globalenergy system FOREWORD As the nations of the world prepare to convene in the United Arab Emiratesfor COP28, the International Renewable Energy Agency (IRENA) continuesto warn that the world is not on track to meet its shared commitments underthe Paris Agreement to avoid dangerous climate change. The pathway to a1.5°C future requires increased global ambition in renewables deployment,enabled by physical infrastructure, policy and regulations, and strengthenedinstitutional and workforce capabilities. Since shortly after its inception, IRENA has tracked trends in the costs andcompetitiveness of renewable power generation technologies, charting thefalling costs of the energy transition beyond most commentators expectations.This has opened up new avenues for decarbonisation via electrification todeliver a climate-safe future, as other options have failed to scale. Francesco La Camera Director-GeneralInternational RenewableEnergy Agency The competitiveness of renewable power today has positioned electrificationas a central pillar of the energy transition. This offers an opportunity toplace renewable energy at the centre of the solution while simultaneouslyenhancing energy security, reducing energy costs and enabling f
