Task 34 Navigation

IEA Wind Task 34
Proposed Revised Vision, Goals, and Work Package

(Revised 05-03-16)

Work Plan WREN encompasses four work packages. Individual organization contributions will vary depending on interests and/or expertise.

WP1: Develop and maintain WREN Hub for
information exchange and collaboration

Description: WREN Hub is a dedicated, publicly available, centralized knowledge management system that offers easy access to existing information. It serves as a go-to location to facilitate collaboration within the international community on wind environmental issues. The hub functions as the platform for fostering international collaboration through a variety of channels. As a centralized location for the collection of and access to knowledge on land-based and offshore wind energy regulatory structures, environmental effects, impact reduction, monitoring methods, and research being conducted around the world, WREN Hub provides access to as much relevant information as possible. It includes effective monitoring practices and strategies for impact avoidance, minimization, mitigation, and compensation, along with other relevant information. WREN Hub is hosted on the Tethys knowledge management system (http://tethys.pnnl.gov).

WREN Hub focuses on information-sharing activities and provides tools for communication and collaboration. It was developed as an online platform for finding information on completed and ongoing research. Specifically, WREN Hub provides access to relevant literature, products and events developed within WREN, key contacts, a calendar of events, and other social media outreach forums. Efforts throughout this initial Task phase include developing the hub and populating it with content, including updates on reports and papers as they become available. Components of WREN Hub (Figure 1) include active aggregation of existing and emerging information, along with access to research results, white papers, key contacts, and pertinent events for the wind community.

Approach: WREN Hub’s development has included a number of steps. The steps, and their respective status, are noted in the list below.

WP2: Develop white papers

Description: WREN members are interested in numerous topics, but information is not readily available within the existing literature. White papers, which focus and facilitate discussion on, and advance the state of, understanding of global concerns within the wind community will be a key output of WREN. White paper topics identified during the initial Task meeting include adaptive management, cumulative impacts, transboundary collaboration, “green versus green” (e.g., balancing the local effects of a wind facility on sensitive species against its global benefits such as reduced carbon dioxide [CO2] emissions), and individual effects to population-level impacts.

Approach: The white papers are being developed by international writing teams. Groups of member nation representatives volunteered to prepare two-page scoping documents for the full set of white paper topics identified during the kick-off meeting. Based on these topic descriptions, the members decided which topic(s) to work on first, because the representatives determined that not all white papers could be developed in the time frame of this Task phase. In addition, because of the interrelationship of the topics, a short document has been developed to describe the relationship and a diagram (Figure 2) was created to visually represent the interrelationship of the topics.

Figure 2. Interrelationship of white paper topics

Members have self-selected which white paper topics to work on, based on their respective interests and expertise. For each topic, an outline and annotated bibliography has been developed and a small writing team has been identified. The resulting drafts will be reviewed by a group of experts as well as all the WREN members. The final products are expected to be peer-reviewed papers.

The adaptive management topic was selected as the first white paper to be fully developed. Publication is anticipated for early 2016. Initial work on a second topic, individual effects to population-level impacts, has also begun during this phase, although it is not expected to be published until 2017. Work has also begun on the green versus green paper. If time and resources allow, additional papers will be started. Although each paper will be developed separately, they might be tied together in a final paper when all are complete.

WP3: Disseminate information

Description: Numerous actions are considered necessary to facilitate information dissemination about WREN and its various activities. Ongoing efforts include a webinar series on recent research findings, tools, models, and other topics as relevant; presentations at key research conferences and other relevant meetings; and other outreach activities.

Approach: Individual outreach activities will be pursued throughout the initial phase of WREN, including the following:

WP4: Conduct other activities

Description: Two activities were conducted within this work package: (1) the design and administration of country-specific surveys to identify common challenges and thematic areas where WREN can make a contribution, as defined by each country’s key stakeholders; and (2) the development of a summary table to include, by country, relevant laws for land-based and offshore wind, the associated regulatory context, compliance mechanisms, and the responsible authority.


  1. The Operating Agent developed an initial draft survey. The final survey was distributed by WREN members, when possible, within their countries to key stakeholders. The survey responses assisted in identifying the challenges and areas where more work is needed to address wind wildlife and environmental issues for land-based and offshore wind. WREN members used aggregated survey results to inform decisions on the highest priority issues to work on in this phase of the Task. This effort may be conducted again as additional countries have joined WREN.
  2. Member nation representatives provided input to a table that includes information on relevant laws, regulatory context, compliance mechanisms, and the responsible authority specific to land-based and offshore wind (as appropriate). Member nations reviewed the summary table and assessed whether there are opportunities for further regulatory comparative analysis. This effort may be conducted again as additional countries have joined WREN.
