BALANCING INFORMATION


1. Real time information on imbalance charges

2. Linepack information (ex-ante, ex-post, historical)

3. Details of TSO balancing actions (nature, timing, volume and cost information)


The TSO shall make public measures taken as well as costs incurred and revenue generated to balance the system

To enable network users to take timely corrective action, the TSO shall publish sufficient, well-timed and reliable information on the balancing status of network users

TRANSMISSION TRANSPARENCY MEETING31 MARCH

• TSO initial proposal1. Identify different balancing regimes2. Required information in each regime identified by NRA and network users3. TSO to commit to project plan to publish information

• No proposal on demand forecasts• No proposal on gas quality• Network User concern that proposal will not meet minimum

transparency requirements

No agreement on way forward

17

GAS STORAGE TRANSPARENCY


1. Improved transparency


Each storage system operator shall make public the amount of gas in each storage facility (…) inflows and outflows, and available storage capacity, including for those facilities exempted from third party access (…) at least every day

18

STORAGE TRANSPARENCY MEETING20 APRIL

• GRI NW regulators, EFET, Eurogas, GSE, European Commission

• Project proposal• Daily publication information at hub level:

– Aggregated storage stocks– Aggregated storage inflows– Aggregated storage outflows

• Preliminary dates: 1 October 2009

30 November 2009SUPPORTED BY ALL PRESENT AT THE MEETING

19

• Third package – proposed Gas Regulation amendments

• GRI NW – estimated project implementation timeline

Third package: the national regulatory authority shall ensure that all such information is made public

20

CONCLUSION

• Programme board supported proposal to use GRI NW as platform for early and coordinated implementation of new third package requirements

• Implementation where there is a clear legal requirement, avoid policy issues like linepack

• Over to the TSOs to make a sensible recommendation– New third package requirements– Commissions proposed guidelines
