Kirloskar Oil Engines

What Kirloskar Oil Engines does

Kirloskar Oil Engines Limited (KOEL) is India's largest non-automotive diesel engine manufacturer and the second-largest player in India's backup genset market, with a top-10 global ranking by diesel generator volume. Headquartered in Pune and operating four advanced manufacturing facilities at Pune, Nashik, Rajkot and Kolhapur (with up to 12 MW dynamometer testing capacity at Kagal), the company runs three business divisions: Power Generation (gensets from 2.8 kW to 3000 kVA / 10 MW contributing ~46% of FY26 revenue at Rs 2,598 crore), Industrial Engines (20 HP to 750 HP serving nine verticals — construction, mining, defence, marine, nuclear, agriculture, fluid handling, railways, and oil & gas), and Fluid Dynamics (residential, agricultural and industrial pumps).

Product technology spans the patented Optiprime multi-core modular power system, Sentinel variable-speed gensets, microgrid and hybrid (solar/wind/hydro/diesel/battery/fuel cell) platforms, India's first hydrogen-engine-based genset, and indigenous development of a 6 MW V12 marine engine (Daksha Program) for the Indian Navy. The portfolio is supported by a 400+ service-centre and 6,000+-engineer aftermarket network, the Kirloskar Care service contract franchise (Bandhan, Bandhan Plus, Anubandhan), the NuLife refurbishment business, the KRMS remote monitoring platform, and the Arka Fincap retail lending subsidiary.

Revenue is generated primarily through B2B enterprise sales of hardware (gensets and engines) with quote-based pricing on multi-year contracts, complemented by recurring aftermarket subscriptions, genuine spares, export distribution across the Middle East, Africa, Asia Pacific and Americas (over 50 countries), and growing hyperscale data centre orders. Direct enterprise field sales for industrial, defence and data centre customers runs alongside a 200+ dealer network across India. FY26 standalone revenue was Rs 7,701 crore (+21% YoY) with PAT of Rs 562 crore (+18%), ROIC of 32.9%, and a stated USD 2 billion revenue ambition by FY30 backed by a Rs 2,100 crore Kagal capex programme.
