10. Influencing factors
• Controlling DC running costs
• Staffing - reasonably controllable
• Connectivity - decreasing
• Energy - increasing
• => focus on energy

13. The Problem!
• Wind energy de-stabilises grid
• Current grid infrastructure can’t take
any more
• Currently 2GW outstanding

22. DC Power Network
• Create a Data Centre power network
• Network generates power for grid by
day and pulls surplus power from grid
by night
• Give control of network to Eirgrid
• Eirgrid can now buy more wind power

33. Conclusion
• Wind power has massive
potential
• Wreaks havoc on grid
• EDM can counter the instability
• => Greater use of wind energy
