LESSONS LEARNED

NOORo I – DUST IMPACT ON PRODUCTION

➢ Mirrors cleanliness impact directly the performance of the plant➢ 2 additional cleaning trucks have been procured in beginning of 2017➢ Mirrors cleanness factor is expected to be higher after the completion of NOORo II & NOORo III

construction

NOORo I - ACTUAL PRODUCTION VS EXPECTED PRODUCTION S2 2016

Overall the production during this semester was good. However it was impacted by following:➢ the cleanliness factor affected by ongoing works in the complex and weather conditions➢ Learning curve of the Operator (NOMAC) especially during cloudy days
