Qatari energy company Nebras Power is planning to invest about $14 billion in Turkey's energy sector  mainly for development of coal power plants and coal mines, said a report.

Nebras Power is a joint venture between Qatar Electricity and Water Company (60 per cent); Qatar Holding, which is owned by Qatar's sovereign wealth fund (20 per cent); and Qatar Petroleum International (20 percent).

This would be one of the region's largest energy projects in terms of size and cost, reported Al-Sharq newspaper citing the company chief.

The Qatari firm is currently in talks with the Turkish government to develop coal mines in the Afisn and Elbistan areas southeast of Ankara, the report stated.

"Along with developing coal mines, the project would aim to build coal power plants able to generate 4,500 MW of electricity, stated CEO Khalid Jolo.

"Nebras Power and Qatar Holding, in cooperation with some of the world's most experienced developers in this field, have begun working on project feasibility studies," he added.
