SAMRA Power Plant, a combined cycle power plant with a capacity of 1160 MW at site ambient conditions, utilizing two 300 MW blocks, each with GE9E gas turbines in 2 x 1 configuration, one 420 MW block with GE132 gas turbines in 2 x 1 configuration, and one block with GE13E2 gas turbine in 1 x 1 configuration. Over the last several years, the Jordanian power grid has struggled to cover peak loads during high-temperature periods. As a result, SEPCO has reviewed potential solutions for increasing power plant generation by installing the Advanced Gas Path (AGP) parts on GE9E turbines and activating an enhanced mode of operation for their 13E2 gas turbines. SEPCO engaged K&M Advisors to evaluate the technical and commercial viability of the AGP installation and operation in enhanced mode. This included a review of the design of generating units, auxiliary equipment, and balance of plant systems to assess their ability to support the increased power output during fogging system and AGP operation.

K&M developed GateCycle models of combined cycle plants to calculate heat and material balances for different ambient temperatures without and with the previously installed fogging system. For each combination of the ambient temperature, fogging system status, and AGP status, K&M developed a spreadsheet summarizing the system power output and power output increase, heat rate and heat rate change, fogging system evaporation rate/demineralized water requirements, and other steam and water impacting operation of HRSG, steam turbine, ACC, and other auxiliary equipment that could be impacted by the fogging system. To analyze the demineralized system requirements, K&M calculated the fogging system demineralized water requirements and the total daily demineralized water demand and compared it with the demineralized water system capacity.  K&M also conducted an economic analysis to determine whether the installation of AGP is economically justified.
