Introduction to Market4RES Questionnaire
This questionnaire has been drafted in the context of the European Project ‘Market4RES’, which is aimed at providing recommendations on the developments to take place in short and long term electricity markets driving a successful and efficient integration of large amounts of RES generation in the long term.

Within this project, Work Package 3 focuses on the conceptual assessment of design options for the developments to take place in short and long term markets. Options here selected as most promising should be further investigated in WP5 of our project with the help of quantitative models to determine which deserve being proposed for their implementation.
A Workshop on the first findings of the analysis conducted within WP3 of the project took place in Brussels on the 24th of June. There, the project team presented their preliminary conclusions on preferred, or most promising, design options, together with those that should be disqualified as contenders because they had some serious drawbacks. Arguments for the selection of best, and worst, design options were provided.

This questionnaire represents a logical continuation of our Workshop and is aimed at collecting useful feedback from relevant stakeholders like you on a set of issues related to the design of markets that we believe are specially critical and controversial, or disputable. Topics to discuss have been arranged into a reduced number of blocks related to main aspects of the functioning of markets both in the long and the short term.

We count on your participation to provide us with very valuable information to take into account in our final analysis and conclusions. If you feel like answering only a specific part of the questionnaire because this is more the most related to your field expertise, do not hesitate to do so. We also encourage you to disseminate this within your institutions looking for complementary expertise.

Many thanks on behalf of WP3 team within the Market4RES project.
