3. Site Selection Page 17
After screening of many sites all over Turkey, Denizli has been figured out as the most suitable site for the CCPP Denizli site Page 18
13/18 km distance to grid connection points 380 kv; gas access ensured by pipeline loop which boarders on Denizli site Project Information - Grid access - Distance to connection point: 2 x 13 km (to new HV-line Denizli & Afyon); 1 x 18 km to Denizli Denizli Afyon connection was looped through the switchyard of the power plant (40) Yatağan Denizli A B Site : 380 kv Connection Points : 380 kv Grid around Denizli : BOTAS Gas pipeline - Gas Supply - BOTAŞ gas pipeline directly boarders Denizli site High reliability in gas supply ensured by pipeline loop Distance to BOTAŞ pipeline (40, 50 bar): 250 m Page 19
Discreet location of the plant minimizes impacts on the direct neighbourhood Power Plant Kaklık Yokuşbaşı Neighbourhood protection Located in an existing small industrial area Away from settlements Low visual impact, e.g. no cooling towers Limited additional noise Operations with low emissions Prevention of flue gas concentration in the surrounding area, e.g. 60 m high stack Connection to nearby gas pipeline and high-voltage grid with very limited impacts Page 20

Further particulars of the plant Little water supplies available, so: Cooling achieved through an Air Cooled Condenser (closed system). Water requirements are taken from local bore holes treated on site. Connection to 380 kv transmission system Scope includes a 380 kv substation, with three incoming lines and a bus coupler in addition to the three generator circuits. Scope includes the construction of the transmission lines on behalf of the Turkish transmission system operator. Fuel gas connection Natural gas only (no other fuels foreseen). Connection to the main gas line, operated by BOTAS/Kentgaz, approx. 500 m from the site. Scope includes this section of gas pipeline. Scope includes the Gas Receiving & Metering Station, including gas tariff metering, filtering, dew point heating and pressure reduction. Page 23
Plot plan Page 24
Contracting Strategy Major Part Turnkey EPC Scope to avoid interface risks EPC Contract for nearly whole plant, including Gas Receiving Metering Station, 380 kv Substation, access road (Greenfield) with: Metka Metal Constructions of Greece SA (part of the Mytilineos Group). Split on shore / off shore Due to tax reasons Metka provided the off shore (=outside of Turkey) part of the contract. Power Projects Ltd. (PPL) provided the on shore (=in Turkey) part of the contract. PPL is a 100% daughter of the Metka group. Non EPC Scope Work Packages outside the EPC Contract, like HV Grid connection, Gas Connections, and several small work packages and specialist consultancy services. Page 25

Denizli Project Successfully delivered Excellent H&S track record Low local standards with 3 LTIs in the first 900 000 worked hours overcome by implementing a clear Safety is first priority philosophy backed-up by management focus. Impressive 4 900 000 worked hours without LTI accrued thereafter Completed within budget By implementing a strict no change philosophy the plant was built within original budget Over-achievement of performance guarantees Guaranteed output 1.8% over-achieved, plant efficiency 1.7% over-achieved Quality very high availability Since start of commercial operation on 03.07.2014 up to end of March 2014 less than 2% forced outage time recorded. Values of 10% and more typical for new-build combined cycle plants in this initial operation phase ( teething problems ) Page 35
Success factors and lessons learned during construction With dedicated work even the most challenging H&S targets can be achieved Implement no-change philosophy in project execution. The project must be defined in the development phase, than it has to be frozen New environments and suppliers require a strict and intensive project management Not having the manufacturer of the main rotating equipment as consortium partner is not recommended Page 36
