← All Solutions01Key Value
Citadel Series.
The next generation of modular natural gas power systems.
Citadel reimagines natural gas generation through standardized Integrated Power Blocks that combine generation, switchgear, protection, synchronization, controls, packaging, and factory testing. It provides a repeatable foundation for mission-critical power and long-term campus growth.

Complete-System Design
Buy an integrated power system rather than a field integration project.
Standardized Power Blocks
Use repeatable engineering to simplify deployment, service, and expansion.
Common Controls
Operate individual blocks and larger campuses through FORTRESS™.
Lifecycle Scalability
Preserve a common operating philosophy as capacity is added.
02Approach
How Nikitis delivers.
The Citadel family includes the TB-1600 and TB-3200 prime power blocks, the FORTRESS Intelligent Control Platform, and the Garrison Configuration for large multi-block installations. Together, they create a unified natural gas power platform rather than unrelated components.
