Overview#
The Olympian GEP220 is a 220 kW diesel generator powered by the Perkins 1106A-70TAG4 — the highest-output variant of the 7.0-liter inline-6 engine in the Perkins 1100 Series generator range. Delivering three-phase 277/480V power at 60 Hz, the GEP220 serves larger commercial buildings, industrial facilities, and institutional campuses that need substantial backup power capacity.
The 1106A-70TAG4 uses enhanced turbocharging and fueling calibration compared to the TAG3 variant in the GEP150, extracting 220 kW from the same 7.0-liter displacement. This shared platform architecture means service procedures, parts inventories, and technician training carry over between the GEP150 and GEP220, benefiting operators who manage multiple Olympian generators across their building portfolios.
At 220 kW, the GEP220 represents the upper range of what the Olympian GEP Series can deliver from the Perkins 1100 platform. It competes with the Cummins C200D6, Kohler 200REOZJF, and Generac SD200 in the 200-250 kW commercial standby segment. For facilities that need more than 220 kW, the step up is typically to a Cat C-Series or Cummins QSB/QSL-powered generator with a larger displacement engine. The GEP220 is the right choice for operators who want maximum output from the Olympian value-tier product line before moving to premium-tier equipment.
