Turkey’s TEIAS chooses ABB technology to integrate renewables into grid

CTBR Staff Writer Published 09 March 2018

Swiss engineering company ABB has secured an order from Turkiye Elektrik Iletim AS (TEIAS) to supply 5000 of its Relion protection and control relays that will help in the integration of renewables into the Turkish transmission grid.

ABB’s Relion protection and control relays are expected to secure electricity transmission for about 30 million Turkish people.

Considered to be one of the largest electricity transmission companies in Europe, TEIAS has an installed capacity of more than 80GW.

As a part of Turkey’s ambitious 2023 renewable integration targets, ABB has been selected to strengthen the intelligence of TEIAS' electrical grid.  

Demand for electricity in the country is expected to grow up to 5% annually and the government intends to diversify its energy sources by increasing the use of renewables including solar and wind power. Turkey has an ambition of installing 20GW of wind power  by 2023.  

As part of the order, ABB plans to install thousands of modern feeder protection and control relays from its Relion family.

ABB says that its Relion features a protection scheme with the earth-fault detection methods and the flexible frequency protection to integrate renewables. 

 Turkish Electricity Transmission Corporation (TEIAS) general manager Abdullah Atalay said: “We have deployed ABB feeder management relays for the integration of renewable energy sources into the developing and growing electrification system of Turkey.

“ABB relays have the comprehensive technical features that are in line with our requirements and expectations. We believe the relays will serve us for long time, herewith we would like to thank ABB for its long-term commitment and collaboration.”

ABB said that the installation of the relays has already begun, and is expected to be finalized during 2018.

The procurement of feeder protection and control relays is a part of the Renewable Energy Integration project in Turkey. The project is financed by the World Bank, more specifically the International Bank for Reconstruction and Development (IBRD) and the Clean Technology Fund (CTF).
