Generator is a type of machine which works on the principle of electromagnetism and converts mechanical energy into electrical energy. It is an essential type of machinery to provide power backup to industrial, commercial spaces and private homes during power outages. Industries, in particular, are heavily dependent upon generators because reliable power supply is critical to avoid disruptions in operations and reduce downtime. Indian generator market is estimated at USD 1.35 billion in 2025 and projected to reach USD 1.74 billion by 2030.
