Cat Hybrid Microgrid Solutions

Integrating Renewable Energy

A sustainable and successful industry, community or commercial installation relies on a dependable utility grid with a clean, consistent, and economical power supply. However, these ideal power conditions are rarely available in remote locations or those with weak infrastructure. That’s where Hawthorne Power Systems comes into the picture, providing fully customizable and scalable microgrid solutions to keep your industries producing, your communities developing, and your people connected.

Hybrid Microgrid Solutions

Caterpillar® is at the forefront of the energy transition, offering a superior alternative to expensive traditional methods of electricity generation. To achieve this goal, we integrate renewable power sources, such as wind and solar, with conventional diesel or gas-fueled power generator sets. These hybrid microgrids, ranging in 10kW to 100MW capacity, also include smart energy storage systems to strengthen power stability and control costs. The result is a flexible power solution that reduces your fuel consumption and carbon emissions, while lowering your long-term operating expenses.


Fully Independent & Customizable

Our microgrids operate independent of the grid and existing infrastructure, making installation possible in the most challenging environments, such as mines and other remote locations. The entire microgrid system is managed through one central control panel, offers flexible fuel options, and is designed for superior performance, using state-of-the art technologies, such as thin-film solar modules. Each microgrid system is created with standardized building blocks configured to your exact specifications.

Microgrid In Action

See how Caterpillar’s largest North American Proving Ground uses microgrid technology to operate completely off grid, 24 hours a day, seven days a week. Formerly, the Tucson, Arizona, site exclusively used three Cat C15 diesel generator sets to power the facility. In 2016, Caterpillar transitioned the site to demonstrate real-world value of its microgrid solution, incorporating a 500 kW solar array and energy storage system. The new integrated system, combining renewable technology with traditional power generation, is expected to reduce fuel consumption by 33 percent and save more than 1,000 tons of CO2 emissions per year.
