Enerjisa Power Generation, a joint venture of Sabanci Holding and E.ON, is developing the Bandirma II natural gas-fired combined cycle power plant in the Balikesir province of Turkey.
The power plant is being erected alongside the existing 930MW Bandirma power plant, the biggest natural gas power plant in Turkey.
The 600MW power project is being built with an estimated investment of $900m and is scheduled for commissioning in 2016. It is expected to operate at an efficiency rate of more than 60%.
The project is expected to create more than 1,000 construction jobs and an additional 40 jobs when operational.
Bandirma-I CCPP details
Enerjisa began commercial operations at its Bandirma-I combined cycle power plant (CCPP) in 2010. With a net efficiency of more than 59%, it is Turkey's most efficient gas power plant and boasts an annual power generation capacity of more than 7,000 gigawatt hours (GWh).
The €550m ($699m) Bandirma-I CCPP took 26 months to complete.
Bandirma II combined cycle power plant make-up
The Bandirma II CCPP is being developed on the southern coast of the sea of Marmara near the Bandirma city in Balikesir province, and covers a total area of more than 85,000m2.
Bandirma II will be a single shaft design combined cycle power plant comprising of a SGT5-8000H gas turbine, a SST5-5000 steam turbine and a SGen5-3000W water cooled generator from Siemens. The plant can increase to full power generation in just 30 minutes.
The Siemens SGT5-8000H gas turbine, with gross power output of 400MW, generates more than 570MW in combined cycle operations. The high-performance four stage gas turbine is equipped with fast acting variable guide vanes to achieve faster cycling capability. It uses Siemens hydraulic clearance optimisation (HCO) active turbine clearance control system to offset engine performance losses.
The SST5-5000 steam turbine, featuring a combined high-pressure/intermediate-pressure reverse flow cylinder and a double flow low-pressure cylinder, is designed to operate at a steam pressure of up to 190bar and steam temperature of up to 600°C. The turbine offers a power output ranging between 120MW to 500MW in combined cycle application.
The Bandirma II plant will use a dry type cooling system with a 135m high cooling tower.
Generation and transmission of power from Bandirma II power plant
The resulting hot gases from the combustion process will be dispatched to the waste heat boiler where steam will be generated. The hot and high-pressure steam will then be sent to turn the steam turbine, for second level electricity generation at the plant.Natural gas mixed with over pressurised gas will be burnt in the combustion chamber before passing through the gas turbine for first level electricity generation.
Steam released from the turbine will be condensed into water in a condenser using cooling water from the tower. Water accumulated at the bottom of the condenser will be sent back to the boilers for further heating.
The electricity generated by the project is planned to be transmitted either to the Balikesir provincial transformer station via an 85km long transmission line, or to Karabiga station via a 70km long transmission line.
Natural gas supply
Natural gas for the Bandirma II power plant will be supplied from the Turkey/Greece natural gas pipeline located near the project site.
Contractors involved with the Bandirma II power project development
Siemens was awarded the turnkey construction contract for the Bandirma II power plant in January 2013. The contractual scope includes the supply of turbines and generators. It also includes the entire electrical system, involving a 400kV high-voltage switchgear installation, and the SPPA-T3000 instrumentation and control system.
The Benson-type heat recovery steam generator (HRSG) to be used at the power plant will be manufactured by NEM.
Kalemci Yapi was subcontracted by Siemens to conduct civil works, while Koza Insaat was engaged to perform earth works.
DOKAY-EIA Environmental Engineering was engaged to prepare the environmental impact assessment (EIA) application for the project.
