Results

We believe that disseminating progress and results is crucial to the success and impact of the DESTRESS project. Lessons learnt will be disseminated to the public. The business cases will be set out with cost and benefit estimates based on the proven changes in system performance. All the steps included in the DESTRESS approach are designed to be transferable to other sites, so that the concepts can become the basis for a standardised procedure in the development of EGS projects.
