Turkey's grid operator urged to publish daily cross-border electricity flows

Turkey's grid operator TEIAŞ has broken down its information for electricity imports and exports by borders by month, but Turkish energy companies have urged the grid operator to publish that information daily.

Last week, Turkish market participants questioned the methodology used in tracking cross-border flows, noticing a discrepancy between the total allocated cross-border capacity and the actual flows published by the transmission system operator (TSO). They pointed out that according to data published by TEIAŞ, Turkey has been importing a daily average of 800MW, or 19,000MWh, since July, which exceeded the maximum allocated capacity figures published by the operator (see EDEM 4 January 2013).

Inflated flows

Following the ICIS report, market participants noted that TEIAŞ has now updated its data to include a monthly breakdown by borders. The latest December figures show that Turkey imported 346MW on the Iranian Başkale-Khoy line and another 38MW on the Doğu Bayazit-Bazergan interconnector to Iran.

Sources also noticed that Turkey imported 580MW from Bulgaria, some 314MW more than the monthly capacity of 266MW allocated on the Bulgarian-Turkish border by both Turkish and Bulgarian TSOs. In exchange, Turkey exported 150MW to Greece, although no capacity was allocated for export to Greece in December 2012, according to the TEIAŞ cross-border auction website TCAT.

"It is possible that there were more volumes imported from Bulgaria in December than the actually allocated limit," a source said. "However, the excess was shipped back to Greece for technical rather than trading purposes."

TEIAŞ confirmed to ICIS that the capacity on the Iranian line could sometimes exceed 450MW, while the capacity with Bulgaria and Greece could sometimes go over the 400MW limit because of different consumption patterns between regions and then settled later by sending energy back. Consequently, TEIAŞ argued, the total border capacity could exceed 1,000MW at peak times.

"It's very important for TEIAŞ to publish this information on a daily basis so we know exactly what comes in and what goes out," the market participant said.

Iranian capacity tender

The market participant also noted that according to an import licence issued by the regulator EMRA in September, only one company - GENT - is importing volumes from Iran. Following an interconnector upgrade, which allows Turkey to import 200MW in summer, 300MW in spring and 400MW in winter, the regulator opened a tender for the extra capacity (see EDEM 7 September 2013). However, since only GENT expressed an interest, it was allocated the full 400MW until 1 January 2013. According to TEIAŞ, that licence has been extended by two months.

Iran is one of the major sellers of electricity in the Middle East, expecting to increase its electricity exports by 47% by March 2013, the end of the current Iranian year, according to unconfirmed Iranian press reports. AS
