Power developments in Turkey

Siemens has received a second order for its H class combined cycle technology from Turkey. The new award is for Bandirma II (600 MW), scheduled for completion in 2016, and the purchaser is Enerjisa, a joint venture of Sabanci Holding and E.ON. The first Turkish order for the H was for the Samsun project, which is currently under construction.

The Bandirma II award brings the total number of Siemens H class gas turbines ordered to date to 28 (see also p 30). Since commercial introduction in 2011 the H class fleet has amassed about 50 000 equivalent operating hours at an availability of more than 97%, says Siemens.
The natural-gas-fuelled Bandirma II will be built on the southern coast of the Sea of Marmara, near the city of Bandirma in the province of Balikesir.

The Siemens scope includes, in addition to the SGT5-8000H gas turbine and turnkey construction of the power plant, the supply of a model SST5-5000 steam turbine and an SGen5-3000W water-cooled generator, along with the entire electrical system, a 400 kV high-voltage switchgear installation and an SPPA-T3000 instrumentation and control system. The scope also includes a Benson-type heat recovery steam generator manufactured by Siemens-owned NEM and the auxiliary and ancillary systems. A long term service contract was also concluded for the gas turbine and generator.

The dynamic power plant market in Turkey calls for flexible and eco-friendly power generation facilities that are also cost-efficient, so that they are right at the top in the merit order, notes Siemens. The single-shaft Bandirma II plant will be able to run up to full power in only 30 minutes, with load ramping gradients of up to 50 MW per minute, and the ability to respond very quickly to fluctuations in power demand to help stabilise the grid.

...and steam turbines for a lignite plant

Siemens Energy is also supplying SST5-5000 steam turbines, along with auxiliary and ancillary systems, for a project of a somewhat different type in Turkey, the lignite-fired Soma Kolin power plant. Siemens' customer for this project is China's Harbin Electric International Company Ltd (HEI), which is constructing the 510 MW facility on a turnkey basis for the Turkish company Hidro-Gen Enerji Ithalat Ihracat Dagitim ve Ticaret AS.
The two SST5-5000 HM-N steam turbines will be delivered between August 2015 and January 2016, and the plant is scheduled to commence commercial operation in April 2017.

The plant is located near the city of Soma in Turkey's western province of Manisa. There are large lignite reserves in this region, and Turkish energy policy attaches great importance to utilising this indigenous resource.

The Soma plant will consist of two units, each rated at 255 MW.

“This is the first order for large steam turbines that we have received from a Chinese company," said Wilfried Ulm, CEO of the steam turbine business unit at Siemens Energy.

MHI invests in CCGT partnership...

MHI of Japan and Ata Kombine Çevrim Santrali Elektrik Uretim Anonim Sirketi, a member of the Istanbul based Üründül Group, have signed a co-operation and strategic partnership agreement that enables MHI to acquire a 50.1% interest in Kirklareligaz Enerji Üretim Sanayi ve Ticaret Anonim Sirketi, which is to build a 520 MW natural gas fuelled combined cycle plant in Kirklareli province, Turkey. The Kirklareligas entity was founded by Ata Kombine Çevrim Santrali Elektrik Üretim Anonim Sirketi for this purpose.

The power plant will be built by a consortium consisting of Mitsubishi Hitachi Power Systems Ltd and Mitsubishi Hitachi Power Systems Europe Ltd. Construction is expected to be completed within approximately 30 months, with the power plant scheduled to enter operation in 2016.

Üründül Group aspires to become a leading player in the Turkish power business.

MHI says the partnership with Üründül is the fourth time it has invested in an overseas power generation project (the three previous cases being AES Energia Cartagena of Spain, Kaliakra Wind Power of Bulgaria, and Pocheon Power of Korea). But it will be more deeply involved in the Kirklareli CCGT plant than in the previous projects. Specifically, MHI says it aims to collaborate with Ata Kombine Çevrim Santrali Elektrik Uretim Anonim Sirketi to ensure that construction is completed on schedule and that, once on-line, the plant will be "operated stably."

...and establishes new nuclear unit to progress Sinop

MHI has established a new business unit, the "Turkey Nuclear IPP Development Department", to step up its involvement in the Sinop nuclear power plant IPP project under development in Turkey. Signifying its strategic importance, the new unit will be directly under the aegis of MHI's Energy & Environment business headed by senior executive vice president, Atsushi Maekawa. The aim behind the creation of the new entity is "to accelerate formulation of the specific project conditions, for example, the financing framework, power purchase agreement, etc" , says MHI.

The Sinop project calls for the construction and operation of four nuclear reactors in the Sinop province of Turkey's Black Sea coast. In October 2013 a broad framework of agreement for the project was reached under what was referred to as a "host government agreement type" commercial arrangement, to be concluded between the government of Turkey and an international consortium including MHI. Detailed negotiations now need to get underway between the two sides, and the role of MHI's new business unit is to "support and accelerate those initiatives", the company says.

The tasks to be performed by MHI's Turkey Nuclear IPP Development Department will include implementation of a feasibility study, negotiation of various contract agreements, preparation of a financing scheme, and planning of localisation and technology transfer.

The plan at Sinop is to deploy the ATMEA1 reactor, a design developed by ATMEA, a joint venture between MHI and France's Areva.
ATMEA1 is an 1100 MW class pressurised water reactor, classified as "Generation III+". In the wake of the Great East Japan Earthquake, ATMEA1 was "positively evaluated" by the French Nuclear Safety Authority (ASN) and the Canadian Nuclear Safety Commission, says MHI.
