TSC Long Term Vision and Integrated Capacity Management ALEXANDER WIRTH, SWISSGRID AG TSC OPERATIONAL MANAGER

Agenda 1. TSC who we are and where we want to go 2. Integrated Capacity Management from tinkering holes to holistic thinking Long-term to hourly forecasting Common Grid Model Grid Security Assessment Capacity Calculation 3. Discussion 2

TSC TSOs and their mission: Reliable, safe and efficient power for Europe. 3

Our initiative Launched in December 2008 Cooperation to foster regional European coordination for system security Decentralised approach (grid security and approval of remedial actions) TSOs remain responsible for system security incl. operational planning TSC's TSOs cover 10 European countries with about 185 million inhabitants and 1.13 million square kilometres. New: Joint Office in Munich (24/7) Open to the participation of other TSOs 4

Strong partnership of equals: TSOs within TSC 5

Good leaders create a vision, articulate the vision, passionately own the vision, and relentlessly drive it to completion. JACK WELSH 6

Our mission To ensure keeping a high level of overall system security in European electricity grid To further enhance operational cooperation amongst TSO To be best in class service provider for grid security assessment and capacity calculation To support member TSOs to provide competitive and reliable services To help TSOs to better manage their expanding operations 7

Our vision TSC grants member TSOs with long-term to real-time control over their operations, with respect to integrating wind energy and handling increases in cross-border trading and electricity transmission. 8

Forecast Data n-1 Results Honing System Security in Europe The TSC IT Platform delivers valuable data to TSOs and security initiatives (centralised or decentralised) TSC is compatible with all (TSO-internal) forms of organization TSC is extendable at will to other TSOs (also in other synchronous areas) Coreso countries Other countries TSC countries 10

Capacity Management Module means a module containing up to date available Cross Zonal Capacity in real time for allocating Cross Zonal Capacity in a continuous manner. ENTSO-E GLOSSARY, NETWORK CODES 11

The steps of Capacity Management Capacity Management is the process of planning, analyzing, sizing, and optimizing capacity to satisfy (current and future agreed) demand in a timely manner and in the most efficient way possible. Change/ Action Monitoring Optimising Analysis Modeling Demand Supply 12

Times they are changing 13

Operational Planning Processes Mid to Long Term Operational Planning (MLTOP) Capacity Calculation (D-2F) Day Ahead Congestion Forecast (DACF), successfully implemented Intraday Congestions Forecast (IDCF), successful testing phase 14

Extending Operational Planning D-2 Forecast of European grid conditions Merging of individual datasets Common Grid Model Capacity Calculation Y-1 / M-1 European LT scenario production Individual LT case production Merging individual cases Calculation and allocation of LT-capacities 15

Common Grid Model (ENTSO-E) TSO B TSO A The harmonisation of individual grid models allows optimised use of available capacities. TSO Common Grid Model (CGM) Capacity Calculation Validation Allocation 16

Grid Security Assessment Static voltage security Topological vulnerability Risk Indices Capability of supplying Power safely Transient security The power grid security assessment is an indices system to prevent accidents and secure safety of supply. There are five kinds of indices: Capability of supplying power safely Static voltage security Topological vulnerability Transient security and Risk indices Overload Low voltage Voltage collapse Angle instability The evaluation results are subjective and dynamic. 17

Capacity Calculation (D-2F) TSC on the way to become a European capacity calculation centre Service provider Service provider linked to capacity calculation One single interface to regional calculation Data hub for necessary information Knowledge provider Single interface to the regional cap calc IT hosting entity or SPOC TSC s TSOs agreed to facilitate the transfer of capacity calculation functions for CWE, CEE and Northern Italian borders form SSC & CAO to TSC Data hub Knowledge provider IT hosting entity or SPOC 18

Intra Day Congestion Forecast (IDCF) Need: Increase of uncertainties, esp. renewables, new devices (PST, HVDC), Intraday Market Objectives Continuous & automatic update of forecast data and security analysis results for coming hours Detect any potential issue on the grid: anticipation Provide information to the TSOs so that they can implement remedial actions on time Ask for power plants to start Cancellation of outage Cross-border remedial actions, redispatching... 19

Improved/additional services As from 1 July 2013, 24/7 rolling forecast process in trial run CTDS Users check and assess the quality of results (model contains remedial actions etc.) CTDS Operation for IDCF rolling forecast performed fully automatically Conference calls to discuss the results of IDCF contingency assessment on demand Parallel operation of DACF and IDCF Rolling Forecast Process 20

Operational Planning Process for Mid to Long Term Horizon TSO A TSOs developed a future proof planning process Process follows ENTSO-E NC OPS requirements TSO MLTOP tool TSO B Planning process is aligned long term system development procedures at each TSC and ENTSO-E (TYNDP) TSO developed a standardised machine and human readable data exchange format Interfaces to Risk Assessment Tools TSO D TSO C 21

You can't just simply plan for capacity and leave it at that. Capacity needs to be managed proactively with proper monitoring, alerting, and optimization. SCOTT HEROLD, IT LUMINARY 22
