8. TSO challenge: Security of Supply
Key issue in maximizing SoS is the capability to anticipate
Planning
Force starting/stopping
of power plant(s)
Cancel grid outage(s)
No time to reinforce the infrastructure
Generation & Grid planning
Mitigation measures
New grid infrastructure (2-10y to be commissioned)
Create political consciousness of adequacy issues  new power plants (210y to be commissioned)

10. Operation closer to the limits – stability
Challenges
• Dynamic Studies: lead to winter import limits of
3500MW
• Decrease in system inertia; due to imports &
renewables: Requires additional challenge & ad-hoc
detailed study
• Limit forecast errors: avoid large deviations & reaching
system limits (i.e 50,2 Hz treshold)

11. Case: Volatility – case of 28.10.2013
Challenge
Today: 400 MW offshore
2020: 2000 MW offshore
> How to handle?

15. Belgian (physical) import:
November 1st – end of Jan (max. MW of the day)
•
•
If > 3500 MW: accepted case by case, only after security check by
experts.
29 days > 3000 MW import; partly for economic reasons (e.g.
19/11/2012 max. 3864 MW).

16. Incompressibility
• Importance of accurate forcasting & nomination
• Elia will check for sufficient export capacity
• Elia can call for additional D-bids
Elia challenges load forecast:
• Opportunity for Stakeholders:
• Any additional flexible bids welcome
• Offer downward volume
• Use the available export capacity

19. What are solutions? combinations of
1. Grid development is KEY
2. Flexible & advanced grid operation
- Controllable devices: PST’s and HVDC
- Dynamic Line Rating (DLR)  active network management
3. Participation of Market Players
- Active use of Intraday information
- balance portfolio both Up- and Downward
- Flow Based
08/10/2013

20. What can you do ?
• Use of intraday programs: Flexibility & firmness.
• Importance of forecasting at market side with focus on limiting
forecast errors
• Operators preparedness: know what to do when Elia sends
specific messages: call for bids / shortage / warnings

23. Context - Supply of ancillary services
 Very high level of market concentration in Belgium
- 1 large player owning almost ¾ of production capacity
- Only 5 producers able to deliver ancillary services, some of them with single
sites only
 Limited flexible fossil plants
- 5500MW inflexible Nuclear (biggest 1076 MW)
- 3700MW CCGTs but non-spinning for economic reasons
 Green energy inflexible by subsidy schemes (€/MWh)

 Energy system is changing rapidly and need for flexibility is urging!
 ELIA addresses this need by conceiving specific products in close
cooperation with stakeholders.
 Demand Side Response and Demand Side Management are important tools
 for ELIA and the DSOs in managing the system security
 for BRPs in self-balancing.
22/11/2013
ELIA Stakeholders Day

26. Demand Side Response (DSR):
market parties react on price signals
 Based on an external price signal (Belpex price, imbalance price,…) market parties,
both on TSO and on DSO-level, may choose to
 consume less
 curtail load during critical peaks
 shift consumption
 self generate
 On Jan 1st 2012, ELIA has introduced single marginal imbalance pricing.
 Some owners of decentralized
production with pass-through
contracts deviate in real time
from their D-1 nominations
in function of imbalance
prices using ELIA website info
 Currently +/-300 MW of
decentralized production
participating to DSR.
 Moreover, BRP-contract in 2014 will allow BRPs to deviate in real time from their
balanced position in order to support the restoration of the system imbalance.

27. Demand Side Management
R1 load: primary reserves through load on TSO grid

Elia developed a combination of asymmetric and symmetric primary reserves
products in order to allow a demand side participation.
Currently Elia has contracted 30,5MW of R1 load.

R1load = tailored to industrial consumers + compliant with Entso-E
requirements




Activated for only deviations > 100mHz leads to a limited number of activations per
year = limited impact on the industrial processes.
Linear modulation of the off-take on the frequency with a max activation time of
30seconds for the entire volume.
Grid users or a pool of grid users (aggregator) connected to the ELIA grid can
participate in the yearly tendering.
The supplier receives capacity fee. No remuneration for the activation.

28. Demand Side Management:
Interruptible load on TSO Grid - ICH



Elia has contracted 261MW tertiary reserves via ICH product.
This ancillary service is directly provided by industrial consumers with flexible
processes and/or aggregators
The impact on the perimeter of the BRP is neutralized by replacing per client the
metering data by the nomination in case of activation.
 Product is adapted to load constraints:



Max 4 activations per year and at least 24 hours
between 2 interruptions
Limited total duration of interruption over the
contractual period (16 or 24hrs)
Use of a predefined load floor = shedding limit
 Highly flexible and fast product



Elia activates this reserve by remote control
Grid user’s offtake must drop below shedding limit within 3 minutes
No notification prior to activation
 This product is the most efficient solution to deal with sudden outages of big power
plants: requires limited number of quick reactions per year.

29. Demand Side Management:
R3 Dynamic Profile (as from 2014)

Elia is procuring currently 10MW of tertiary reserves sourced from large DSO
customers as a pilot project. Based on this experimentation and supported by
CREG, ELIA has contracted for 2014 50MW of R3 Dynamic Profile.
This ancillary service is directly provided
by aggregators; aggregation is allowed over
different DSOs and different BRPs/suppliers
covering both load and generation with 100%
availability.
 Additional complexity when developing a
DSO- oriented product as no nominations,
what is exact activation split per BRP,
impact on supplier,…


A pragmatic solution was elaborated in close cooperation with stakeholders
(Expert WG) avoiding a negative impact on the concerned stakeholders

Further enhancements under analysis, in close cooperation with stakeholders.

30. Demand Side Management:
Free bids via APP (Aggregated Power Plant)



As from 2013, ELIA allows BRPs to sign a contract for an “Aggregated Power
Plant” which is constituted by a portfolio of different flexible generation units
and loads connected to TSO and/or DSO grid that are part of the concerned
BRP portfolio.
Elia can activate this extra flexibility in its
daily balancing activations when available
The provider is remunerated for the activation at
the offered price. These free (negative) prices
allow RES to recuperate their opportunity costs
in case of output reduction.

31. Bidladder platform
= platform where market players can bid in all
available flexibility via explicit portfolio bidding
with locational information.

allow free bids from
 load and RES flexibility;
 flexibility connected to the distribution grid.
 3 different balancing energy products:
 Fast Standard product
 Slow Standard products
 Emergency products
 “block”-products which do not reflect
necessarily the physical constraints of
underlying resources. Differences between the product and physical
reality need to be considered in the price when bidding to Elia.
