ATTACHMENT 10 COMMISSIONING STANDARDS AND PROCEDURES

1. Procedures for Cold Commissioning and Payment at 2MW, 4MW, 6MW & 8MW

Once the Contractor has determined that it is ready for cold commissioning at each stage of 2MW, 4MW, 6MW and 8MW outputs (“Cold Commissioning Stage”), the Contractor shall carry out the Cold Commissioning of the Facility in accordance with procedures set forth herein below:

a) DABS and USAID shall be given not less than seventy-two (72) hours prior notice by the Contractor of the Cold Commissioning and any retest of any part thereof. Representatives from DABS and USAID shall be allowed to be present at and observe all such tests.

b) The Engineer (as defined in the Power Purchase Agreement) and, upon USAID’s sole discretion, a USAID third party Quality Assurance engineer, must be present during each Cold Commissioning Stage.

c) At each Cold Commissioning Stage, the verification process of the cold commissioning will include, but is not limited to: (the “Cold Commissioning Tests for the Facility”)

• Verification of the MW output.

• Visual inspection at all parts and components of equipment (solar PV panels, cables, conduits, joint boxes, invertor(s), mounting structures, grounding system, step up transformer(s), switchgear(s) and related equipment. All equipment, as stated above, will be tested without load to check functionality and output.

• Review of the automation and control system and all the measuring instrumentation and the operation of the system.

d) After the successful completion of the Cold Commissioning Tests for the Facility, the Engineer (as defined in the Power Purchase Agreement) shall issue a Certificate of Cold Commissioning for the Facility at each Cold Commissioning Stage to DABS and USAID for acceptance.

e) Once accepted, the Contractor shall present each Certificate of Cold Commissioning for the Facility to USAID for payment in accordance with Section B.4 METHOD OF PAYMENT of the USAID Contract.

2. Procedures for Hot Commissioning and Payment at 10MW

Payment for Contractor’s successful completion commissioning of 10 MW will be conducted in accordance with the technical outputs specified herein below and in accordance with this USAID Contract Section B.4 METHOD

OF PAYMENT.

a) Upon issuance of the Seller Interconnection Testing Completion Certificate (as defined in the PPA) and acceptance by DABS and USAID, the Contractor must carry out the Hot Commissioning Tests of the Facility.

d) The verification process of Hot Commissioning will include, but is not limited to the following:

• Verify that the installation of all 10 MW Solar PV Plant related equipment (solar panels, mounting structure, joint boxes, invertor(s), step up transformer(s), switchgear(s), grounding system, control system and etc.) is complete and is as per the accepted design, according to the contract documents and industry accepted standards.

• Verify that the installation is safe within accepted industry standards.

• Verify that the installation is visually acceptable.

• Verify that all components of the installation are robust and permanent.

• Document as-built conditions.

• Verify system proper performance of all equipment.

• Verify all control systems performance an operation.

• Verify the switchgear and associated equipment are functional.

• Verify proper interconnection point with the 20 kV.

• Verify proper performance of the metering panel and make sure the meters are tested and sealed in the presence of DABS and USAID representatives.

• Verify the system is generating 10 MWp AC at secondary side of the transformer.

• Verify proper system operation.

• Complete any required acceptance documentation.

• Train the system owner on basic system operation.

• Verify that the operations and maintenance (O&M) documentation and manuals left on-site are complete.

After the successful completion of the Commissioning Tests for the Facility, the Engineer shall issue the Certificate of Final Commissioning for the Facility to DABS, the Contractor, and USAID.

e) The Contractor shall present the Certificate of Final Commissioning for the Facility to USAID for payment in accordance with Section B.4 METHOD OF PAYMENT of this USAID Contract.

3. Scheduling and Accommodation of Additional Tests

The Contractor may repeat the commissioning tests as many times as required by DABS and USAID to meet the test criteria set forth herein.
