1. Supported by Excursus: How Competent Bodies could deal with the 12 months lifetime of RES-GO Christof Timpe (c.timpe@oeko.de) Second Workshop “Making Guarantees of Origin and Electricity Disclosure in Europe more reliable”, Brussels, 8 July 2010 www.reliable-disclosure.org

2. 8 July 2010, Second EPED/RE-DISS Domain Workshop 2 Principles of the proposal on the 12 months rule 1.GO shall be issued on a monthly basis and as timely after each metering period as possible. –For small plants, metering periods may be up to 12 months. 2.Disclosure shall be based on the calendar year (= disclosure period). 3.GO shall be used for the 12 months disclosure period in which the production period has started. 4.The lifetime of GO is further restricted by a transaction deadline for all GO, which shall be defined as 3 months after the end of a disclosure period. All GO relating to this disclosure period will become invalid at this deadline and their attributes will flow into the Residual Mix. Exceptions from 3. and 4. apply for those GO which could not be issued until 2 months before the GO transaction deadline. In this case, the GO may be used for the following disclosure period.

3. 8 July 2010, Second EPED/RE-DISS Domain Workshop 3 Concrete steps of handling GO  Electricity is generated and consumed within year X.  Most GO are issued on a monthly basis (exceptions may apply for small plants), issuing takes place as soon as possible after the production.  31 March year (X+1): General deadline for the transferability of GO relating to production periods which have started in year X. –After this period these GO are collected and go into the Residual Mix. –Exceptions apply for GO which have been issued after 31 January year (X+1): These GO may be used for disclosure in year (X+1). –Option: The transferability of these GO could be restricted to [two] months after issuing.  In April and May of year (X+1) the accounting of attributes and the Residual Mix calculations take place.  Disclosure information can be provided as of June or July year (X+1).

4. 8 July 2010, Second EPED/RE-DISS Domain Workshop 4 What does the proposal mean for GO?  GO are generally used for the 12 months disclosure period (calendar year) in which the related production period has started. –Exceptions apply only for those GO which can only be issued after 31 January of the year following the disclosure period.  GO issued before or on 31 January year (X+1) for production periods starting in year X: –They must be used until the deadline of 31 March year (X+1). (This implies a lifetime of less than 12 months for most GO.)  GO issued after 31 January year (X+1) for production periods starting in year X: –They can be used for disclosure in year (X+1). –Option: Their transferability could be restricted to [two] months after issuing.
