Renewable power generation can help countries meet their sustainable development
goals through provision of access to clean, secure, reliable and affordable energy.
Renewable energy has gone mainstream, accounting for the majority of capacity
additions in power generation today.Tens of gigawatts of wind, hydropower and
solar photovoltaic capacity are installed worldwide every year in a renewable energy
market that is worth more than a hundred billion USD annually.
Other renewable power technology markets are also emerging. Recent years have seen dramatic reductions in renewable energy technologies’ costs as a result of R&D and accelerated deployment.
Yet policy-makers are often not aware of the latest cost data. International Renewable Energy Agency (IRENA) Member Countries have asked for better, objective cost data for renewable energy technologies.
This working paper aims to serve that need and is part of a set of five reports on solar pholtovoltaics, wind, biomass, hydropower and concentrating solar power that address the current costs of these key renewable power technology options.
The reports provide valuable insights into the current state of deployment, types of technologies available and their costs and performance.The analysis is based on a range of data sources with the objective of developing a uniform dataset that supports comparison across technologies of different cost indicators – equipment, project and levelised cost of electricity – and allows for technology and cost trends, as well as their variability to be assessed.
The papers are not a detailed financial analysis of project economics. However, they do provide simple, clear metrics based on up-to-date and reliable information which can be used to evaluate the costs and performance of different renewable power generation technologies.These reports help to inform the current debate about renewable power generation and assist governments and key decision makers to make informed decisions on policy and investment.
The dataset used in these papers will be augmented over time with new project cost
data collected from IRENA Member Countries.The combined data will be the basis for
forthcoming IRENA publications and toolkits to assist countries with renewable energy
policy development and planning.Therefore, we welcome your feedback on the data
and analysis presented in these papers, and we hope that they help you in your policy,
planning and investment decisions.
