Common use of Tests Upon and After Synchronization of the Complex and Commissioning Tests Clause in Contracts

Tests Upon and After Synchronization of the Complex and Commissioning Tests. (a) After first synchronizing the Complex, initial operational testing of the Complex shall be conducted by the Contractor. Once the Contractor is satisfied that the Complex is capable of c ontinued reliable op eration, the C ontractor sh all r equest the E ngineer t o i ssue the Certificate of R eadiness. Upon the issuance by the E ngineer of t he C ertificate o f Readiness, the Contractor shall so notify the Employer and carry out the following tests (the “Commissioning Tests”), which if the Complex satisfies the minimum performance criteria therefor, will result in the Complex being Commissioned and in the establishment of the Commercial Operations Date in accordance with Section 9.3(c)(iii): (i) initial Tested Capacity test; (ii) reliability run test; (iii) automatic voltage regulator droop; (iv) turbine governor operation, including a steam governor over speed test; (v) reactive capability; (vi) minimum load capability; (vii) response of Complex to step load changes; and (viii) full load rejection Minimum pe rformance c riteria for t he C ommissioning T ests are i ncluded in The Commissioning and Testing Schedule. (b) Reliability Run and initial Tested Capacity. Upon completion of the reliability run test prerequisites as included in Schedule [●], the Contractor shall de clare to t he E mployer t he c ommencement o f t he reliability r un test (including t he test u nder Section 9.3(a)(i)). D uring t he 30 (thirty) day period of t he reliability run test, the initial Tested Capacity of the Complex will be determined in the following manner: (i) The Complex shall be in operation at full output with normal auxiliaries and full colony load, if connected directly to the Complex, in service.
