The pilot version of the Professional Module will be take place in June 2021 during the First GrEnFIn Summer Training, the purpose of which is to test the content and methodology of the learning path. It will be an unmissable opportunity to experience technical issues on green energy and sustainable finance, quantitative analysis and topics in economic policy and business, coherently with the practices and the needs of a large array of market and operational contexts. In this regard, Professional Module is designed in 3 sections: the first two sections are composed of video lessons held by experts from the energy companies and University Partners that are part of the Consortium. In this first phase of the project these sections will be not compulsory, but freely accessible by professionals after the subscription on the official GrEnFIn platform - specifically the access to section 2 is only allowed after passing a learning verification test on the topics of Section 1 - and they will be made available from May as preparatory training for Summer Training. The 3days of Summer Training from 7 to 9 June 2021 (originally planned in Katowice and redesigned later online due to the pandemic situation) will be focused to the development of the section 3, represented by a case study on a very topical issue for the energy sector.
