DS3 - RES Integration and System Services
EirGrid – An All-Island Energy Company
EirGrid – An All-Island Energy Company
* Note: In Ireland ESB owns the transmission and distribution system
So why is Ireland relevant…?
* Based on analysis of National Renewable Action Plans (NREAPs) as submitted by Member States
EirGrid is seeing the impacts first…
* Based on analysis of National Renewable
Energy Action Plans (NREAPs) as submitted by EU
Member States
which if not solved lead to operational limits…
Wind Curtailment LevelsMaximum Allowable Real Time Wind Level
SNSP = Wind + Imports
Demand + Exports
Change in System Performance
which is incentivised by
System Services
Changes in System Policies
which leads to increases in
renewables
DS3 delivers transformational change
System Tools enabling operational change in the Control Centre

What is Demand Side Management
System Operator
Demand Side Unit
Dispatch Instruction
Dispatch notification
System Benefit
• Greater
accommodation of
variable RES
• Enhanced capacity
adequacy
• Avoided / deferred
network investment
Industry Customer
Dispatch notification
Reduces Load
ConsumerBenefit
• Reduced bills
• Greater control over and
engagement with the
energy they produce
and consume
The Evolution of Demand Side Management in Ireland…
Medium-scale DSU, increased number of demand sites & site complexity
Demand Side Units (DSU), low number of demand sites
Large-scale Demand Side participation across all demand, including residential level

DS3 – Focus on services at times of scarcity
DS3 – Focus on reliable performance
Safe, Secure Operation up to 65% SNSP with wind generation in excess of 4 GW
What has DS3 delivered for us so far?
SNSP = Wind + Imports
Demand + Exports
But have we really been tested?
Hurricane Ophelia
• System demand similar to a Christmas Day profile
• Pre-emptive wind curtailment improved system stability & security
• Multiple 110 kV faults but no system stability issues
Wind generation helped stabilise system
