About the Working Party on Renewable Energy Technologies (REWP)

The principal objective of the Working Party on Renewable Energy Technologies (REWP) is to provide advice to the IEA Committee on Energy Research and Technology and other IEA bodies on renewable energy sources and technologies, related policies, trends, projects, programmes and strategies which address the energy security, diversity and environmental interests of IEA Member countries.

As part of the IEA’s Global Engagement Strategy, the REWP also increasingly encourages collaboration with IEA partner countries and international bodies such as the International Renewable Energy Agency (IRENA).

The REWP oversees the work of the ten IEA Technology Collaboration Programmes (formally known as Implementing Agreements) dedicated to renewable energy and hydrogen sources. Finally, it ensures a dialogue between governments and the private sector by monitoring the role of finance and markets through the Renewable Industry Advisory Board (RIAB), an informal body created by the CERT in June 2011. 

For the timeframe of 2013-15, the REWP has devised a Strategic Plan and REWP Mandate.

Renewables in the Mainstream: Towards a "Third Way" for electricity market design?
24 March 2015, Paris France

The generation from renewable sources is now at the same level as that from gas and twice that from nuclear generation. Much more is expected and needed to deliver a low carbon energy system, but this raises questions about how energy markets are best operated and regulated to facilitate additional deployment.

  • Where are renewables now being deployed on a commercial basis? What are the factors limiting such growth?
  • How can liberalised energy markets be adapted to better accommodate high shares of renewables?
  • What are the key issues for renewables within regulated markets and how can they be overcome?

The IEA Working Party on Renewable Energy Technologies (REWP), with the active participation of its Renewable Industry Advisory Board (RIAB) members, hosted a workshop bringing together senior decision makers from the key players worldwide: governments from IEA and partner countries, technology providers, utilities and project developers. Discussion of specific and concrete examples allowed a debate on the key elements needed to transform the energy system to one underpinned by high levels of renewable energy supply. The event built upon IEA secretariat work on policy and market design, including a recent series of workshops within the framework of the IEA Electricity Security Advisory Panel (ESAP). The results of this event provided an essential contribution to current IEA activities and publications on electricity market design and the IEA Grid Integration of Variable Renewables (GIVAR) programme.


Renewables & Innovation in Technology, Business Models & Policy
25 March 2014, Paris France

The renewable energy (RE) sector is a critical player in the current energy revolution. Progress has been promising; with growth in RE power generation generally in line with what is needed to meet IEA low-emissions scenario targets. But a number of challenges need to be overcome to continue this promising trend. Innovation in technology, overall energy system design and integration, business models and opportunities, and regulatory frameworks, is the key to transforming these challenges into opportunities. This workshop examined these opportunities across the whole RE value chain, proposing recommendations on the conditions and actions needed to stimulate and catalyse the needed innovation.

The workshop brought together senior decision makers from governments, technology providers, utilities and project developers.


Scaling Up Financing to Expand the Renewables Portfolio
9 April 2013, Paris, France

Meeting the challenge of ramping up RE deployment quickly enough to be on track to reduce emissions requires high rates of deployment right across the technology portfolio. The deployment of some renewable energy technologies has been growing strongly - particularly on-shore wind and PV. The deployment of the some other technologies – notably offshore wind, CSP, bioenergy, and geothermal - needs to be accelerated in order to meet long-term climate change goals.

Finding financing solutions for the required broad portfolio of technologies is one of the major challenges in meeting these goals. Some of these technologies carry higher real or perceived risks, which tend to raise the costs of and decrease the availability of finance.


From Mediterranean Plans to Renewable Energy Power Plants
3 October 2012, Rome, Italy

Organised by the IEA Renewable Energy Working Party and the IEA International Low-Carbon Energy Technology Platform, this regional workshop was held in collaboration with GSE, OME and RES4Med, and under the auspices of the Italian Ministries of Foreign Affairs and Environment, Land and Sea.


Renewables – Policy and Market Design Challenges
27 March 2012, Paris, France

Despite the challenging economic situation, the renewable energy industry has been growing rapidly. Renewables play an essential role in all sustainable energy futures. Growing the industry at the rate required in these scenarios presents a formidable challenge. Are current policies sufficient to allow this momentum to be maintained? How do policies and markets need to evolve to provide the conditions in which investment in renewables and other low-carbon technologies can flourish?

To help identify concrete steps which can be taken by industry, governments and international organisations the IEA’s Renewable Energy Working Party organised a workshop, the latest in its annual series, to discuss these challenges and to identify some concrete actions which can be taken.
