Deliverables

Documents, reports (2)

Flexibility needs for future energy systems

Reporting the flexibility needs from the future electricity and energy systems market for geothermal systems, presenting the main findings from T4.1. The results allow clear insights on the design requirements for future flexible geothermal systems.

Quality Management Plan and Project Management Handbook

It outlines the meeting structure, evaluation and review systems for the project and all milestones and deliverables, risk identifications and mitigations and gender equality management. It will be reviewed and validated every six months. It also contains WPS and Gantt chart, a schedule per task and lists the responsible partner.
