The diesel generator market growth is attributed to extensive exploration and production activities across the world to meet the growing demand for energy. In addition, exponential infrastructure development, coupled with rising urbanization is predicted to augur well for the market. For instance, In February 2019, A pact was signed by France’s Naval Group and Australia of a worth USD 35 billion to build 12 attack class submarines for the Australian Navy. The construction is scheduled to start in late 2023 and suppliers for the top five submarine components such as main motor, diesel generator, batteries, switchboard, and weapon discharge system will be announced soon.  


Massive Population Growth Continues To Increase The Demand For Power

According to the United Nation's report released in July 2019, the world’s population is projected to increase by 2 billion in the next 30 years, from 7.7 billion currently to 9.7 billion in 2050. Over 90% of the population growth will come from developing countries which typically have low electrification rate. The considerable population growth will inevitably increase the power shortfall, which ultimately provides healthy growth for the industry.
