Fukushima Workshop – Revitalising local economies with renewable energy

The IEA RETD Technology Collaboration Programme, together with the Japanese New Energy and Industrial Technology Development Organization (NEDO) hosted a workshop in Koriyama-city in the Fukushima prefecture in Japan on 1st September 2016 focusing on the revitalisation of local economies with renewable energy. The study with the same name was launched at this event.

Following the Fukushima nuclear incident, the Japanese government decided to reduce the dependence on nuclear power as much as possible by promotion of energy efficiency and acceleration of renewable energy. As a recovery process, the Fukushima prefectural government acknowledged the need to revitalise the local economy by expansion of renewable energy implemented by local communities.

By linking results from international research and sharing experiences from different IEA RETD TCP member countries, the Japanese government hopes to actively support the acceleration of renewable energy in the Fukushima region.


The workshop was organised in three parts:


The workshop was attended by over 30 participants, from the Japanese government, local researchers, students and renewable energy project developers, Japanese media and IEA RETD TCP members.

RES-E-MARKETS Workshop, Paris

The IEA Secretariat,  IEA-RETD and FTI-CL Energy hosted a workshop on Friday 30th October 2015 in Paris to explore the market design issues associated with power systems with a high share of variable renewables, and to discuss the preliminary findings of the RES-E-MARKETS study.

The objective of the study is to provide policy recommendations for the direction of the reform of the current market and regulatory frameworks in the IEA-RETD member countries and beyond, in order to accommodate high shares of renewable energy in a timely, cost-effective and secure fashion.

The workshop was structured in four slots:

  • General analysis framework
  • Energy only market prototype
  • Prosumer market prototype
  • State-led and vertically integrated prototypes.

In the first part of the workshop, FTI-CL Energy presented the approach, the structure of the analysis and the preliminary findings of the study. Valuable high-level comments from more than 40 international experts were then given and will be integrated in the study.

The project is expected to be concluded in February 2016.

FIN-COMMUNITY Workshop, Oxford

The IEA-RETD and Ricardo AEA hosted a workshop on the initial findings from the current FIN-COMMUNITY project analysing whether community projects have higher or lower costs for building and operating wind and solar projects compared to commercial projects of a similar size.

The FIN-COMMUNITY study is analysing the main costs (development and planning costs, construction costs, operating costs and taxation costs) in five countries (Australia, Canada, Denmark, Germany and the UK) which each have differing policies and support for community energy.

The discussion focused around four main themes:

  • Development costs
  • Construction costs
  • Negotiating deals to sell electricity
  • Finance

Main takeaways and questions for policy makers

  • What is community energy policy all about? Is it about subsidising projects in locations where commercial developers would not invest? Or about unblocking supply constraints for community investors wanting to build in favourable locations?
  • Who is community energy meant to benefit? Local investors, project developers, communities?
  • Key is consistency in stability of support schemes with no threats of (retroactive) changes
  • Grants and low-interest loans can help to overcome risks during the development phase
  • ’How-to’-guides can help to reduce development costs, as can standardised agreements and models. However, communities probably benefit most by having a professional project manager who has experience of delivering similar schemes. Public sector bodies in some jurisdictions offer this support for free.
  • Consideration should be given to having Government backed banks supporting the sector, e.g. acting as a secondary, junior lender
  • How to build a good reputation for community-led projects?

The final report, along with key recommendations for policy makers is anticipated in mid-October 2015.

IEA-RETD Workshop, London

The IEA-RETD hosted a workshop on current key topics of Renewable Energy Technology Deployment. The workshop provided an opportunity to learn more on the activities of IEA-RETD, in particular three ongoing state-of-the-art studies of IEA-RETD followed by an interactive discussion amongst the participants.


The workshop addressed three main topics:

1. Renewable Energy Finance

IEA-RETD Report: Cost and financing aspects of community renewable energy projects (FIN-COMMUNITY)

Gregory Vaughan-Morris, Ricardo-AEA

The key barriers faced by community energy projects are generally well understood, however, there is much less information available about the actual cost and financing implications of these projects. The FIN-COMMUNITY project seeks to identify, document and assess the cost and financial impacts faced by community-owned renewable energy projects compared to commercial renewable energy projects.

2. Energy Storage

IEA-RETD Scoping Study: Policies for Storing Renewable Energy (RE-STORAGE)

Paul Robson, E4tech

The RE-STORAGE scoping study aims to answer the question “Everybody is talking about storage  – what is important for policy makers?” by giving an overview of policy relevant aspects relating to renewable energy and storage. It will explain no-regret policies and provide a guiding framework that allows policy makers to set priorities in a large scale uptake of RE scenario.

3. Renewable transport policies

IEA-RETD Report: Next Generation Policy Instruments for Renewable Transport (RES-T-NEXT)

David de Jager, Operating Agent IEA-RETD

The RES-T-Next project aims at providing an analysis of next generation RES-T policy instruments and recommendations regarding private and urban transport in order to increase the level of energy used from renewable sources and to decrease GHG emissions.

Joint IRENA – IEA-RETD REMAP workshop: Roadmap to Doubling RES

Global Energy Prospects: Roadmap to Doubling Renewables in the Global Energy Mix

On 29 November 2013, IRENA and IEA-RETD jointly organised a workshop that aimed to discuss key factors for achieving the goal of doubling the global renewable energy share by 2030 based on IRENA’s findings from 26 country studies. Its purpose was to identify opportunities for collaboration among international organisations, policy-makers, industry representatives, and scientists.

The meeting followed Europe’s Renewable Policy Conference (EREC 2013) in the same venue. Nearly forty people participated in the workshop. The participants included intergovernmental agencies, government agencies, academic organisations, industry representatives, and private firms in the renewable energy field.

The workshop discussed ways to achieve the doubling of renewables in the global energy mix by 2030, based on the results from analysis conducted within IRENA’s Renewables Roadmap for 2030 (REmap 2030) initiative. The workshop was organised around four technical sessions (map overall results, biomass, grid and storage needs in the roadmap, and socio-economic benefit of RE deployment) and roundtable discussion. IEA-RETD presented its work on next generation policy instruments for renewable electricity (RES-E-NEXT), and on economic co-benefits of renewable energy technology deployment (EMPLOY).
