As part of the SPIRE PPP initiative, the SOLPART project participated to the Impact study of SPIRE projects in April 2017. Following this, we were invited to participate to the SPIRE Impact workshop (https://www.spire2030.eu/news/new/spire-impact-workshop-17-may-2017). The 7th Impact Workshop on the contractual PPPs (cPPPs) was organized by the European Commission on 17 May 2017. The workshop gathered together representatives from a range of Horizon 2020 projects funded under recent cPPP calls and members of the cPPP Partnership Boards to discuss their experiences. This was the first time that three cPPPs have presented together in a single Impact Workshop with the aim of learning from each other’s experiences. The focus was not just on technical aspects but also societal and business impact. The workshop looked to share best practice and increase the potential impact of cPPP projects after the end of the current funding period and to collect evidence on the leverage and impact generated by the cPPPs in general, including as part of the mid-term review on cPPPs that is currently underway.
