Description

Diesel Generator Market Summary

The global diesel generator market size was estimated at USD 19.33 billion in 2025 and is projected to reach USD 40.99 billion by 2033, growing at a CAGR of 9.9% from 2026 to 2033. A diesel generator operates by combusting diesel fuel within an internal combustion engine to produce mechanical energy, which subsequently drives an alternator to generate electricity.

Continued technological progress in power generation systems and increasing adoption of distributed energy solutions are major factors fostering market expansion.

The rising demand for reliable backup power, particularly in regions with unstable grid networks, along with growing requirements across the industrial, commercial, and residential sectors, is also strengthening demand in the emergency power diesel generator industry.

Diesel generators remain extensively used for standby, prime, and continuous power applications, where medium- and high-capacity units are preferred due to their durability, operational flexibility, and cost-effectiveness. Their ability to deliver instant power during outages and support critical operations in sectors such as healthcare, manufacturing, data centers, and construction further reinforces market growth. The ongoing expansion of infrastructure projects in countries such as the U.S., Japan, India, and China, along with supportive government investments in industrial development and power reliability improvements, continues to drive the adoption of diesel generators globally.

How Do Licenses Work?

How Do Licenses Work?

The primary function of a report license is to define how many people within a company are authorized to use the purchased report. This is separate to how a report might be delivered. Unless specifically identified otherwise, the purchase option is Single User. Below is a helpful description of that license, along with a sampling of others most commonly offered.

  • This license allows only one user to have access to and to use/read the report. It is not one user at a time or one user group; it is an individual who will be reading and utilizing the report.

  • This license allows for the entire purchasing company to read and use the report. This is the license level that would allow for a report to be placed on an internal company shared drive for access by all employees of that direct company. This license does not extend to parent or sister company use.

  • This license is designed to allow an entire department within a company full access to a report. The departmental license is a great option for companies that have more than one location and the department is spread out all over the country/world

  • This license is for companies that have one location where they want the report to be accessible by all employees within that physical location.

  • This is the most flexible of the licensing options. Some publishers will allow you to get a license for a preset number of people (typically 5). These licenses are ideal for small work groups.

License options are at the discretion of each publisher. As such, not all licenses indicated above are available for every product. If you are uncertain of the best license for your needs or would like a license that is not proactively available, please contact us and we will be happy to assist.
