half-sibling. More importantly, it sets the bar much higher in an ever developing industry, from both generation capacity and environmental point of view. MetCap Energy Investments will use General Electric's FlexEfficiency technology for its new integrated renewables combined cycle (IRCC) power plant, which is planned for construction in Karaman. The plant will enable flexible operation by integrating a next-generation 50 Hz 9FB gas turbines, a steam turbine, an oversized generator, 22 MW of GE wind turbines and 50 MW of eSolar concentrated solar thermal tower technology - all integrated by a GE Mark VIe plant control system. The plant is expected to have a power generation capacity of over 1000MW, which is sufficient to power more than 2,300,000 homes. The plant is expected to begin its commercial operation in the fourth quarter of 2015.Metcap Energy Investments together with General Electric invested in California-based concentrating solar power (CSP) technology developer eSolar. eSolar, launched by Idealab founder Bill Gross, has long-term licensing agreements for its standalone solar technology with NRG Energy and other companies around the world. This is further evidence that Metcap is a firm believer in the part renewables should play in meeting our future energy needs. The design is based on a new model of General Electric's natural gas plant called FlexEfficiency, which is able to vary its output rapidly to make it a good dance partner for variable sources like wind and sun.Since the early days of the electricity market, efficiency has been a deciding factor for the plants design and feasibility. According to the calculations, the CCGT is expected to produce over 59 per cent efficiency at site conditions. If we are to consider the two inexhaustible energy sources - wind and sun, the plant at its height will produce above a 70 per cent efficiency with an annual average of above 67 per cent. This makes it one of the most important projects not only in Turkey, but also in the energy projects development market around the world. In the markets where natural gas availability is limited and the supply side costs are high and volatile, such efficiency is a very important advantage from a financial point of view. This advantage is also backed up by engineering improvements made in order to accomodate 210 hot start stops, a start up time of under 30 minutes at site and all-related precautionary measurements Left: The TrilemaRight: Model for Project Dervish built to scale" All industry experts agree that more important than where you produce your electricity is where you flow your production"050 ENERGY security

such HRSG stress monitor - the most complicated Plant Control System, with full automated start / stop sequencers, ever to be developed by General Electric.Environment is always top priority. Everyone leaves a footprint, unfortunately, but conscious understanding, measuring and investing in technologies that minimise these effects is very important. The plant has Zero Liquid Discharge. It recycles rain and storm water as well the operational steam and water used in the plant. It leaves no suspicion of a fluid related pollution. The plant is backed up with air-cooled chillers. In all, it uses 1.4 lt/sec including the cleaning water for the mirrors. This definitely is a new industry standard. All regulatory standards around NOX and Air Dispatch modelling, Vibration Measurements, Near and Far Field Noise Levels and Social Impact have been taken into consideration and have been set at the most stringent of all available standards - IFC, EU and Turkish Regulatory Law. All industry experts agree, that more important than where you produce the electricity, is where you flow your production. The project taps into 72 per cent of the power consumption in Turkey: Ankara - the capital, in the north; Antalya - Turkey's fastest growing city, in the south.; and Adana - one of Turkey's oldest industrial cities, in the east. When all energy markets are being formulated on an understanding of the Merit Order, efficiency, flexibility, environmental impact, healthy grid and start up times requirements will come into effect. From all points of view, Project Dervish will make everyone's approach to both CSP tech nology and the integration of renewables into conventional fuel systems, whirl around. The Turkish plant will be in commercial operation by 2015. Future plants with higher efficiency factors and further integration of Wind, Desalination and Solar are already being developed. n ABOUT THE AUTHORKerem Metin is the Vice Chairman of Investments and Operations at Metcap Energy Investments.
