MarketsandMarkets projects the global generator market will grow from USD 26.79 billion in 2026 to USD 35.38 billion by 2031, representing a 5.7% CAGR. The report links expansion to investment in reliable energy infrastructure, energy-security priorities, rural electrification, grid resilience and rising demand for backup and prime power. Advances in engine technology, hybrid systems, digital controls and smart monitoring are improving efficiency, emissions performance and operating economics. Indirect sales are expected to hold the largest share by channel, while stationary generators are projected to dominate by design. North America is identified as the second-largest regional market, supported by grid constraints, extreme weather, critical-infrastructure demand and data-center expansion. Caterpillar, Cummins, Mitsubishi Heavy Industries, Rolls-Royce and Generac are listed among the key companies.
