18. Risks - Interaction with non-EL Users Electrical Network Consolidation Project Non-EL Users Some works planned by non-EL users will require the availability of some parts of the networks concerned by the EL consolidation Some new needs will have to be taken into account by an “upgrade” part of the project 18JP.

20. Next Steps Beginning of the study phase in June; The study phase will require the collection of user needs for upgrade; Objective of the study phase: define a general strategy for all SPS sites, end 2015. 20JP. SferruzzaLIU-SPS 22/07/2015

21. Project Costing A detailed cost breakdown for the consolidation works will be provided after completion of the study phase; Funding for the consolidation will be covered by EL-SPS & ACC-CONS; The cost of dedicated upgrades for projects such as LIU shall be covered by the project concerned. 21JP.

Memo Identification of concerned projects and project leaders For each project, electrical load schedule to be studied with the help of EN/EL Validation End Study Phase Beginning Design Phase Objective: first installation works during EYETS 2016 2016

24. Collection of User Requirement - Parameters List of electrical loads, location; Rated power; Absorbed power; Power factor; Nominal voltage; Load profile; Load criticality; Space required; Planning of installation and commissioning. 24JP. SferruzzaLIU-SPS 22/07/2015

25. Conclusion A wide project for EN/EL, able to ensure the reliability of the SPS electrical supply for the next 30 years; Good opportunity to coordinate upgrade and consolidation works in a single project; The Study Phase requires the collection of user needs for upgrade (for end of October 2015); General strategy for all SPS site to be determined by the end of the year. 25JP.
