Generator Systems (GenSets)
Overview
Nik Khavar Fars Power Plant utilizes a modular gas-engine-based generation architecture designed to deliver reliable and scalable distributed power generation. The facility operates multiple natural-gas-fueled generator sets supplied by leading global manufacturers.
Gas engine generator sets are widely used in distributed generation power plants because they provide:
• high electrical efficiency
• flexible modular capacity expansion
• fast response to grid demand
• high operational reliabilityNatural gas generator systems are particularly well suited for distributed power generation due to their relatively low installation cost, operational flexibility, and ability to integrate with combined heat and power systems.
The power plant currently operates several generator technologies including Jenbacher gas engines and Caterpillar gas generator systems, which together form the plant’s distributed generation capability.
Jenbacher Gas Engine Generator Units
Jenbacher Natural Gas Generators – 2 MW Class
The initial generation units installed at Nik Khavar Fars Power Plant were Jenbacher natural gas generator sets, each with a nominal electrical output of approximately 2 MW.
Jenbacher engines are widely deployed worldwide in distributed generation applications due to their high efficiency, reliability, and long service intervals. Jenbacher gas engines can operate in power ranges from several hundred kilowatts up to approximately 10 MW depending on the model.
These generators formed the first operational generation capability of the plant and were successfully installed, commissioned, and synchronized with the regional power grid.
Key characteristics include:
• natural gas fueled reciprocating engines
• high efficiency distributed power generation
• reliable base-load operation
• compatibility with combined heat and power applications
Jenbacher J616 Gas Engine Generators
As part of the power plant’s capacity expansion program, additional generation capability was installed using Jenbacher J616 gas engine generators.
The Jenbacher J616 belongs to the Type-6 series of high-output gas engines, designed for large industrial and utility-scale distributed generation systems.
Typical characteristics of the J616 engine include:
• electrical output up to approximately 2.4–2.7 MW per unit
• electrical efficiency up to 45.7%
• V16-cylinder high-power gas engine design
• high reliability for continuous power generation
• compatibility with combined heat and power systemsJenbacher Type-6 engines operate in the 2–4.5 MW power range and are widely used in industrial power plants and decentralized energy systems around the world.
The installation of J616 units significantly increased the plant’s generation capacity while maintaining the modular distributed generation design.
Caterpillar Gas Generator Units
To enhance operational flexibility and diversify generation assets, the power plant also integrated Caterpillar natural gas generator units.
Caterpillar gas generator sets are commonly used in industrial and utility distributed generation applications due to their robust design and proven reliability. These systems incorporate advanced engine control technologies that improve fuel efficiency, emissions performance, and operational stability.
Caterpillar generator sets are widely recognized as one of the leading solutions for distributed generation and industrial power production, with extensive global deployment in power plants, industrial facilities, and utility projects.
Key features include:
• high reliability and industrial durability
• advanced engine control and monitoring systems
• flexible operation for grid-connected power plants
• strong global service and maintenance support
Modular Generation Architecture
The power plant’s generation units operate in a parallel modular configuration, where multiple gas engine generators work together to supply electricity to the grid.
This distributed architecture provides several operational advantages:
• scalable generation capacity
• redundancy and operational resilience
• flexible maintenance scheduling
• improved grid response capabilityInstead of relying on a single large turbine generator, the modular gas engine configuration allows the plant to progressively expand generation capacity while maintaining high availability.
Operational Reliability
By combining multiple generator technologies from internationally recognized manufacturers, Nik Khavar Fars Power Plant has established a robust distributed generation system capable of supporting reliable electricity production and long-term operational sustainability.
