This books contains a collection of progress reports from the participating contractors in
the wind energy R&D sub-programme within the JOULE (Joint Opportunities for
Unconventional or Long term Energy supply) programme on non-nuclear energy and
rational use of energy which is implemented by the Commission of the European
Communities, Directorate-General XII for Science, Research and Development.
The wind energy sub-programme is intended to promote and coordinate research and
development in the field of wind energy in the twelve member States of the European
Community and, under special conditions, also in the six member States of the EFTA
treaty. Contracts have been signed between the Commission and the various contractors -
usually research centres, universities, consultants and industries- to carry out r&d projects
which, apart from particular cases, have been selected among those which applied to an
open call for proposals in wind energy r&d. The average duration of a research project
in this programme is two years and the average number of participants in at is
about four. As a general rule, the Commission provides financial support up to 50% of
a project's total cost under the condition that at least two contractors from different
member States are involved. The latter restriction, however, is waived in case of small
and medium enterprises. Each project is led by a coordinator who is responsible for the
technical and financial coordination of the research group and holds regular contacts with
the Commission staff in Brussels who manage the programme. Furthermore, some
experts, consultant to the Commission, supervise the individual projects.
The projects described in this document are just part of the activities undertaken by the
Commission of the European Communities to favour the diffusion of wind energy in
Europe. Indeed, other important programmes, downstream of r&d, are being
implemented byr Directorates-General of the Commission, such as Thermie,
Altener, Valoren and Value.
The current wind energy programme consists of 25 multi-partner projects which are
closely interrelated and cover a broad spectrum of topics.
These are grouped within the following research areas:
A: Wind measuring and modelling
B: Wind Turbine experiments and utilisation
C: Development of components and models
D: Stand-Alone and offshore
E: Large-wind turbines
The total contribution from the Commission to the programme is about 8 MECU over
a period of two years. This corresponds to about half of its total cost. Most of the
research work was actually started by beginning 1991. Hence, one should not be
surprised if some of the enclosed papers do not report on achieved results but rather on
work programme and objectives of the relevant projects. It is envisaged to organise a
— in — work programme and objectives of the relevant projects. It is envisaged to organise a
contractor meeting every year whereby all contractors are invited to bring along written
report on the progress of their project in a publishable and unrestricted form.
The Maastricht contractors meeting, which lasted three days i.e. from 12 to 14 June 1991,
was organised in the following way. In the first day all project coordinators presented
orally the status and objectives of their projects. The papers here enclosed have been
prepared for such purpose. The following two days were dedicated to the meetings of the
various project teams. These were held in separate rooms and parallel sessions but access
to these rooms was in most case allowed to public. Furthermore, each participants
contributed to the preparation of posters which were shown for all the duration of the
meeting.
This contractor meeting, which was held at the MECC congress centre of Maastricht, was
organised jointly by the Commission of the European Communities and ECN
(Netherlands Energy Centrum) in collaboration with NO VEM (Dutch Agency for Energy
and Environment), NEDWIN, Holec Project, Windmaster Netherlands, Stork Product
Engineering. About 120 delegates from the Community and EFTA countries participated.
The Commission is particularly grateful to Mrs. C.A.L. Ruitenburg of ECN Public
Relation Office and Miss. N. Sneijders of MECC for their excellent organisation of this
important event.
