The global diesel generators market is projected to grow at a moderate growth rate accompanied by growing industrial, commercial, and residential activities. Power deficits, unreliable and uneconomical power supplies from the grid, low capital cost of diesel generators, mature technology, and ready fuel availability are the key factors driving the growth of the diesel generators market. Diesel generators are the most preferred power backup solution and accounted for more than 80% of the global generators market in 2017.

Energy demand in developing countries is growing in line with their infrastructural growth and economic development, whereas in developed countries it is increasing, although slowly, as a result of further improvement in people’s lifestyle. Utilities are not always in a place to accommodate this increasing power demand by investing in large power projects, as these projects require long construction times and huge capital investment.

According to the report, China was identified as the top country for the diesel generators market in terms of market volume, followed by the US and India. In 2017, in terms of market volume, China held an 18.2% share in the global market and is expected to hold 19.50% in 2022. China still lacks an extensive national grid; rural areas are not adequately connected. To support economic growth in these areas, the government is promoting distributed generation, which is expected to benefit the generators market.
