Presentation made by Katrien Verwimp at the RECS Market Meeting 2013 in Berlin. Presenting the Greencheck (Groencheck) an innovative instrument of VREG - Flemish Electricity and Gas Regulator for disclosure. Disclosure is providing information to electricity customers on origins of their electricity supply

1. How customers benefit from
information on the source of their
electricity –
The case of Flanders
• How is disclosure regulated in Flanders?
• Using the ‘Groencheck’
to inform and empower customers

2. Belgium federal state
• 3 regions: Flanders, Wallonia, Brussels
• 4 Energy regulators:
• Federal level: CREG
• Regional level: VREG, CWaPE, Brugel
• Responsabilities divided between policy levels
• Federal responsabilities
• Regional responsabilities
• RES-E (support systems, GO’s, …)
• Disclosure

3. Disclosure in Flanders
Disclosure of the origin of the electricity supplied in
previous year:
• yearly VREG report and on the suppliers’ invoices
• RES-E and CHP only allowed when proven by GO’s
• Fossil and nuclear: proven by corrected production
data
• Remaining fossil and nuclear is exported to the RE-
DISS residual mix
• RES-E: monthly GO cancelation => ‘Greencheck’

4. Import of Guarantees of
Origin
• Flanders is a net GO importer
• GO import raises the RES-E consumption in
Flanders from 11,5% to 52 % (2012)
• Extra stimulus by partial tax exemption for RES-E
consumption
• Up and untill 2012
• Fallen away starting from 1/1/2013 (R.Decree
27/12/2012)

6. Why expand the RES-E
disclosure system
Green electricity products are popular
1.Individuals wonder: how is individual RES-E
consumption proven?
2.Public debate on the origin of the RES-E
products
• Domestic vs. foreign RES-E
• Type of energy source

7. Proof of individual RES-E
consumption
• Risk of double disclosure, based on the same GO
• Not at registry level
• Theoretical example of double disclosure:
• Supplier offers 1 ‘grey’ and 1 ‘green’ electricity product
• Assumption: All his consumers have the same
consumption
• He tells 90% of his customers they receive a full RES-E
product
• He tells the regulator that only 10% of his customers use
RES-E, and cancels only GO’s for this amount
• =>The same GO has been double-disclosed 9x
7

8. Avoid double disclosure
• Link GO cancelation to individual consumers
1. Option of consumer account in GO registry
• Consumer can check himself the amount of GO’s
cancelled for his consumption
• With large number of residential RES-E consumers:
Many accounts = Huge contact management
1. Option of linking individual consumption data
from Grid Operators to GO cancelation
• Works for all consumers
• Demands coöperation of all DSO’s

9. Monthly ‘GreenCheck’ for
RES-E consumers
• Based on individual acces point and consumption
• Reporting mechanism with cooperation of Suppliers
and Grid operators
• Monthly cancelation of GO’s by the green electricity
suppliers for their customers
• On VREG website: every customer can verify if the
individually consumed RES-E was proven to be RES-
based through GO cancelation by the supplier, using
his individual EAN code

13. How does it work?
Monthly ‘Green reporting
procedure’ (1/4)
• Electricity suppliers
• Report a list of all acces point EANcodes of their RES-E
consumers of the past month of supply N
• Including the %RES-E and the Grid Operator GLN code
• By the 3rd working day of the month N+1
• VREG
• Recombines the lists of all suppliers to lists of RES-E
consumers per Grid Operator
• Sends these lists to the Grid Operators
13

14. Monthly Green reporting
procedure (2/4)
• Grid Operators:
• Receive the list of all RES-E consumers (on working day 4 of month
N+1)
• Add to every consumer the individual consumption of the past
month N
• Send the completed list back to VREG (by working day 12 of
month N+1)
• VREG
• Calculates the amount of RES-E supplied per supplier in MWh
• =amount of GO’s to cancel per supplier
• Alerts all suppliers of their amount of GO’s to cancel 14

15. Monthly Green reporting
procedure (3/4)
• Suppliers
• Cancel their ‘quotum’ of GO’s (within 10 working days)
• VREG
• Checks whether suppliers did cancel enough GO’s to
proof their promised RES-E supply
• This % of compliance is added in the webtool
• This webtool is linked to the database of all reported RES-
E consumers for that month N
15

16. Monthly Green reporting
procedure (4/4)
• Consumer
• Fill in the EANcode of his acces point at
www.vreg.be/groencheck
• Get to see the % of RES-E in his consumption that was
proven to VREG by GO cancelation by his supplier
• = For the past 12 months
• Procedure: BESL-2011-7
16

17. Benefits of this procedure
• Consumers information
• = key element in liberalized market
• Random inspection of suppliers proportions of
GO cancelation

18. Why expand the RES-E
disclosure system
Green electricity products are popular
1.Individuals wonder: how is individual RES-E
consumption proven?
2.Public debate on the origin of the RES-E
products
• Domestic vs. foreign RES-E
• Type of energy source
18

19. Next step: expand the
‘Greencheck’
Answer to the public debate concerning the
origin of the RES-E products
• Domestic vs. foreign RES-E
• Type of energy source
19

20. Info on the origin of the
RES-E products
• Information added in Disclosure report of 2012, per
supplier:
• Plan: integrate this information in the
‘Greencheck’, per electricity product
