    Turkish firms raise questions over border data mismatch

    by Aura Sabadus



    Turkish electricity companies have urged grid operator TEIAS to start
    publishing real-time import and export information for all borders to
    avoid uncertainties related to flow data.

    A participant active in cross-border trading noticed that electricity
    imports have increased well above the allocated capacity levels since
    July 2012, and it is difficult to account for some of that capacity.

    "Even [state incumbent] EÜAS has started publishing data regarding
    maintenance schedules at their plants," he said. "It would be very
    helpful to everyone if TEIAS were to offer real-time import and export
    data broken down by each border."

    According to data published by TEIAS, Turkey has been importing more
    than 19,000MWh on a daily basis since July, equating to just under
    800MW, although the maximum allocated capacity should have been less
    than the figures published by the operator.

    Import sources

    Turkey currently imports a maximum 400MW from Bulgaria and Greece, and
    upgraded its interconnector to Iran from a 230kV to a 400kV line in
    September 2012 (see EDEM 7 September 2012). Thanks to the upgrade,
    Iranian capacity can be scaled up from 200MW in summer, 300MW in
    spring and 400MW in winter.

    A source at TEIAS told ICIS that state wholesaler TETAS was importing
    an average 40MW from the unrecognised republic of Nagorno-Karabakh via
    a Georgian interconnector.

    However, the source stressed that Georgia itself had not been
    exporting electricity to Turkey since August 2012. She also added that
    there were no exchanges between Turkey and neighbouring Syria, Iraq
    and Armenia.

    Given these limitations, Turkey can import at its maximum 840MW from
    Bulgaria, Greece, Iran and Nagorno-Karabakh, a figure that is still
    some 150MW below the data published by TEIAS. According to TEIAS
    reports published on 4 January 2013, Turkey imported 25,488MWh,
    averaging 1,062MW per hour, and exported 2,184MW, averaging 91MW per
    hour, on Thursday.

    Another source at TEIAS confirmed that the capacity on the Iranian
    line could sometimes exceed 450MW, while the capacity with Bulgaria
    and Greece could go over the 400MW limit because of different
    consumption patterns between regions.

    The difference could then be settled later by sending energy back from
    Turkey to Bulgaria and Greece.

    Consequently, the TEIAS source argued, the total border capacity could
    exceed 1,000MW at peak times.

    However, a second market participant described the explanation as
    "unconvincing", pointing out that there were doubts whether Turkey was
    actually importing over 400MW from Iran, as the capacity allocated to
    a private firm was 150MW only.

    Data needs

    The first market participant said accurate data was crucial to
    Turkey's ambitions to introduce a liberalised and transparent energy
    market.

    "Turkey has great ambitions to establish a reference energy exchange,
    EPIAS," he added. "It is an absolute must for such an exchange to
    publish transparent real-time data."

    The Bulgarian-Turkish border has become highly attractive to companies
    active in the region as prices have been robust since June 2012,
    out-turning at levels between E6.10/MWh to E22.32/MWh since June 2012.
    The highest price was recorded in July 2012, when the border
    out-turned at E22.32/MWh. AS
