(3) At all relevant points, transmission system operators shall publish historical information on the requirements of paragraph 3.3(1)(a) to (g) for the past 5 years on a rolling basis. U.K.

(4) Transmission system operators shall publish measured values of the gross calorific value or the Wobbe index at all relevant points, on a daily basis. Preliminary figures shall be published at the latest 3 days following the respective gas day. Final figures shall be published within 3 months after the end of the respective month. U.K.

(5) For all relevant points, transmission system operators shall publish available capacities, booked and technical capacities, on an annual basis over all years where capacity is contracted plus 1 year, and at least for the next 10 years. This information shall be updated at least every month or more frequently, if new information becomes available. The publication shall reflect the period for which capacity is offered to the market. U.K.

3.4. Information to be published regarding the transmission system and the time schedule according to which this information should be published U.K.

(1) Transmission system operators shall ensure the publication on a daily basis and updated every day the aggregated amounts of capacities offered, and contracted on the secondary market (i.e. sold from one network user to another network user), where the information is available to the TSO. This information shall include the following specifications: U.K.

(a)

interconnection point where the capacity is sold;

(b)

type of capacity, i.e. entry, exit, firm, interruptible;

(c)

quantity and duration of the capacity usage rights;

(d)

type of sale, e.g. transfer or assignment;

(e)

the total number of trades/transfers;

(f)

any other conditions known to the transmission system operator as mentioned in 3.3.

In so far such information is provided by a third party, transmission system operators shall be exempted from this provision.

(2) Transmission system operators shall publish harmonised conditions under which capacity transactions (e.g. transfers and assignments) will be accepted by them. These conditions must at least include: U.K.

(a)

a description of standardised products which can be sold on the secondary market;

In so far such information is provided by a third party, transmission system operators shall be exempted from this provision. The provision of this information shall respect confidentiality of commercially sensitive information. U.K.

(4) Where flexibility services, other than tolerances, are offered for third party access, transmission system operators shall publish daily forecasts on a day-ahead basis of the maximum amount of flexibility, the booked level of flexibility and the availability of flexibility for the market for the next gas day. The transmission system operator shall also publish ex-post information on the aggregate utilisation of every flexibility service at the end of each gas day. If the national regulatory authority is satisfied that such information could give room to potential abuse by network users, it may decide to exempt the transmission system operator from this obligation. U.K.

(5) Transmission system operators shall publish, per balancing zone, the amount of gas in the transmission system at the start of each gas day and the forecast of the amount of gas in the transmission system at the end of each gas day. The forecast amount of gas for the end of the gas day shall be updated on an hourly basis throughout the gas day. If imbalance charges are calculated on an hourly basis, the transmission system operator shall publish the amount of gas in the transmission system on an hourly basis. Alternatively, transmission system operators shall publish, per balancing zone, the aggregate imbalance position of all users at the start of each balancing period and the forecast of the aggregated imbalance position of all users at the end of each gas day. If the national regulatory authority is satisfied that such information could give room to potential abuse by network users, it may decide to exempt the transmission system operator from this obligation. U.K.

(6) Transmission system operators shall provide user-friendly instruments for calculating tariffs. U.K.

(7) Transmission system operators shall keep at the disposal of the relevant national authorities, for at least 5 years, effective records of all capacity contracts and all other relevant information in relation to calculating and providing access to available capacities, in particular individual nominations and interruptions.
