2 Introduction This monitoring report has been prepared in order to document the emission reduction achieved by implementation of 24 MW Bandırma-3 WPP(WPP) and impact of the Project on sustainable development. The monitoring report is based on Gold Standard principles and involves impact of project on Sustainable Development Indicators in addition to emission reduction calculations. Realized emission reduction has been significantly lower than estimates due to the failure in meeting the estimated electricity generation figure arising from insufficient wind power. Project Description The Bandırma-3 WPP has been developed by Asmakinsan Temiz Enerji Elektrik Üretim Sanayi ve Ticaret A.S.(Asmakinsan) Project has been commissioned by end of February 2010 but the monitoring period has been started by march In this scope, Asmakinsan has installed 10 x 2.5 MW Nordex N90 Wind Turbines at the Southwest of Bandırma town near Bezirci and Çarıkköy in the province of Balıkesir with the purpose of contributing to national economy and growing electricity demand. Total installed power of the facility is 24 MW initially. Therefore, output capacity of one of the turbines had been limited to 1.5MW by the manufacturer and controlled by TEIAS through a sealed meter installed at the exit of the turbine. After commissioning (in April 2011), the limitation on Turbine#10 has been removed and electrical capacity has become 25MW. Since the initial financial analysis and emission reduction calculation had been made for 99GWh and project cannot reach to 99GWh even after capacity is increased to 25MWe, this change will not affect the additionality and emission reduction calculation. Actual generation which is significantly lower than expected during monitoring period has also demonstrated this fact. 1

11 lake compared to another WPP which is very close to the Bandırma-3 WPP. Since a monitoring study has already been conducted for the nearby plant and no interaction has been detected, risk for Bandırma-3 has been assessed as lower. However, to ensure, a monitoring study has been conducted by plant staff in periods similar to the nearby plant referred.

Actual Value For Parameter More than 150 people have been recruited during implementation of the project for construction and electrical activities. List of the staff recruited under different subcontractors have been provided to DOE. Total number of staff recruited during operation period has been realized as 16 including 5 staff working in the plant, 5 staff in Bursa and 4 staff recruited through the security company and 2 through the turbine supplier.

13 price. Future target for parameter Decrease natural gas consumed for electricity generation. Approximately consumption of 25 million m 3 of natural gas is expected to be avoided corresponding to 6.5 million annually. Actual Value For Parameter During monitoring period, about 17.4 million m 3 NG has been saved which corresponds to 4.2 million. Way of monitoring How Through comparing electricity generated by Bandırma-3 WPP and natural gas that would be used to produce the same amount of electricity according to baseline scenario. When By who Yearly Project developer No 12 Indicator Mitigation measure Chosen parameter Current situation of parameter Future target for parameter Technology transfer and Self reliance Mitigation measure is not required for this indicator. Equipment expenditures None To be determined during implementation phase. Actual Value For Parameter 10 turbines have been purchased and installed. Agreement has been provided to verification DOE. Way of monitoring How Review of purchasing agreements. When By who Yearly Project developer Indicators compared to Baseline Scenario Comparison of the target value of parameters with the realized situation has shown that the scoring made during validation is realistic. Some of the indicators (balance of payments, air quality etc) which are dependent on realization of estimated electricity generation have not reached the target values due to the generation realized below estimations however still they have made significant contribution in improving the indicators compared to baseline situation. In order to monitor impact on bird population, observations have been reported by project owner once in November 2010, twice in January 2011 and once in march The observers have monitored the project site recorded on video during the year corresponding to the migration period and observed 12

14 interaction of turbines with the birds. No interaction or impact on bird migration has been observed during the site inspections. The reports for bird migration have been submitted to DOE. Project is located at a lower altitude compared to other power plants which are closer to the coastal area and located at higher altitudes. Observations made for this purpose by plant staff which are recorded and submitted to DOE also have shown that there is no interaction with birds. Since Bandirma-3 WPP is located at lower altitudes and is out of the migration route to wetlands in the area as given in passport, no interaction is expected in the future. The future target for Quantitative employment and income generation has been achieved. The target for recruiting 15 staff during operation has been achieved when staff recruited due to project activity through security and turbine supplier companies are also considered. Total number considering two technicians from turbine supplier has been determined as
