The Primorskaya wind electric plant (WEP) is a new 200MW onshore windfarm being constructed in the Zaporizhia region of Ukraine.

The project is being developed in two phases by DTEK Renewables. Construction of the first 100MW phase was commenced in 2016 with operations began in February 2019. The 100MW phase two is set to become operational in October 2019.

The facility will generate electricity to power more than 350,000 homes in Ukraine and help the nation meet its target of 11% renewable energy generation by 2020.

Primorskaya windfarm make-up

The Primorskaya windfarm was constructed on the Sea of Azov shore in the Zaporizhia region. Phase one of the project encompasses 26 3.8MW 130 110HH wind turbines supplied by GE.

The rotor and nacelle of each turbine are based on a tubular steel tower with varied hub height options.

The diameter of the turbine’s rotor is 130m, while its swept area is 13,273m². The sound level of the turbines during normal operation is 107dB(A).

Digital substation technology and grid connection

The transmission infrastructure for phase one of the Primorskaya windfarm included a 150kV central power distribution station and two 150/35/10kV substations. GE supplied high-voltage equipment for the central power distribution station and substations.

Primorskaya WEP is the first Ukrainian project to feature GE’s digital substation technology, which generates automatic real-time alerts on the status of the equipment. It also provides information on disruptions or failures in the equipment.

The digital substation (DS) technology integrates a digital data exchange system, which is based on the IEC 61850 uniform communications protocol. It also includes a protection and control unit, measuring units, and condition-monitoring systems.

DS technology offers reliability and situational awareness and ensures a greater utilisation of resources, which cannot be provided by a conventional substation. It digitalises all the analogue data at the source and provides information to the personnel via fibre-optic communication links.

“The facility will generate electricity to power more than 350,000 homes in Ukraine and help the nation to meet its target of 11% renewable energy generation by 2020.”

The substation features a dual star architecture based on parallel redundancy protocol (PRP), which protects all interconnection controllers and protection terminals.

GE MiCOM P546 differential terminals will be used as part of digital substation technology. The terminals provide high-speed current differential unit protection to the cable lines. GE MiCOM P446 relays serve as standby terminals.

A compact HYpact hybrid switchgear is provided by GE for the windfarm. It integrates earthing switches, disconnectors, and circuit breakers (CBs). The hybrid switchgear ensures economic substation designs, better operational planning, and enhanced space availability.

The solution also reduces environmental influences on switchgear and act as an economic alternative to gas-insulated substations.

The Primorskaya WEP is be connected to the Ukrainian national grid.

Primorskaya windfarm financing

A syndicate of four German banks is offering a €90m ($104m) loan for the first phase of the Primorskaya windfarm. The ten-year term loan is guaranteed by the German export credit agency (ECA) Euler Hermes.

Led by Bayerische Landesbank, the syndicate includes KfW IPEX-Bank, AKA, and Bremer Kreditbank.

GE Energy Financial Services supported DTEK for raising project finance for stage one of the Primorskaya windfarm.

Contractors involved

GE Renewable Energy signed a contract with DTEK for the installation and maintenance of 26 turbines in January 2018. It is also responsible for the maintenance of the turbines for a period of 20 years.

DTEK placed a contract with GE Renewable Energy for the supply of an additional 26 turbines for stage two of Primorskaya’s wind project in October 2018.

GE Power’s Grid Solutions division received a contract to supply transmission equipment and systems for the distribution and substations of the plant in June 2018.
