Oil from Iraqi Kurdistan stored at Turkey's Mediterranean port of Ceyhan has reached 2.8 million barrels, Energy Minister Taner Yildiz said, adding that a second export cargo for Kurdish oil has not been loaded yet.
Yildiz also said oil flow via Iraqi Kurdistan pipeline continued at 100,000 barrels per day (bpd).
Iraqi Kurdistan shipped its first cargo of piped oil via Turkey last month but the tanker carrying one million barrels of Kurdish crude has changed course twice abruptly and has not yet discharged oil.
"Power generation (from hydro power plants) is almost half of last year's in the April-May-June period," Yildiz also said.
Hydro power generation accounts for about 25 percent of Turkey's total power generation. Because of its booming energy needs, Turkey's energy bill has ballooned to around $60 billion annually.
