Microgrids are self-sufficient energy systems capable of generating their own power, traditionally via generator sets or turbines. Microgrids can operate independently or in conjunction with the electrical grid/utility.
Hybrid energy solutions (HES) are microgrids that involve a combination of power sources. They can combine proven cost-effective renewable energy from wind or solar sources with conventional diesel- or gas-fuelled generation. They can also employ energy storage to add power system stability and enable further energy cost reduction.
Distributed energy resources (DERs) are typically small-scale microgrids or hybrid energy solutions that are usually situated near sites of electricity use, bringing energy generation closer to the point of use.
Fully integrate renewable energy, battery energy storage, and conventional power generation with a full range of Cat® Hybrid Energy Solutions from 10 kW to 100 MW. Supported by your local Cat dealer, we are with you at every phase of your hybrid energy project—from installation and regular service for optimal operation to product upgrades, financing services, warranty, service agreements, and parts availability. We will customize our hybrid energy technologies to meet your business and industry needs.
Caterpillar is at the forefront of the energy transition, integrating renewable power with smart energy storage and conventional diesel-, gas-, or renewable-fuelled power generation to provide:
Maximize Resiliency and Savings with Battery Energy Storage Systems (BESS)
Energy storage systems are a key component in a hybrid microgrid and guarantee short-term backup power. Caterpillar can provide on-site energy storage systems to help stabilize transient loads, supply and absorb alternating current (AC) power, increase renewable energy source utilization, and transfer energy from time-of-generation to time-of-use. Stored energy can also be used to participate in grid services markets to avoid costs or receive financial compensation.
Benefits of Battery Energy Storage Systems
Find out more about the various BESS models including Power Grid Stability (PGS), Mobile Power Grid Stability (PGS HD), Energy Time Shift (ETS), and Energy Capacity Expansion (ECE), as well as Compact ESS available for rent or purchase.
The Microgrid’s Command Center
The Cat Microgrid Master Controller (MMC) acts as the hybrid energy solution’s command center, coordinating the different energy sources and enabling them to work as a single entity. Managing every source in the entire system, the MMC ensures the community loads are connected in the most economical way.
Cat MMCs Feature:
Total System Management
The MMC integrates a variety of traditional and renewable energy sources to provide overall monitoring and control of all connected hybrid energy solutions assets. They include:
Caterpillar offers a choice of MMCs designed for industrial/commercial applications. They integrate a variety of traditional and renewable energy sources within a hybrid energy solution by providing optimized monitoring and control.
Traditional Power Generation and Renewable Liquid Fuels
Cat hybrid energy solutions enable seamless renewable energy integration with traditional power sources, such as on-site Cat generator sets. These generator sets can provide a much-needed backstop when renewable resources, including wind and solar, are not available.
Flexible Fuel Options
All Cat diesel generators can run on biofuels and have accommodated the use of biodiesel and hydrotreated vegetable oil (HVO) for over a decade. These fuels are available now and can help reduce lifecycle greenhouse gas emissions compared to diesel.
Cat gas generator sets can also run on a variety of lower-carbon intensity fuels depending upon the model. These include:
Photovoltaic Solar Modules
Solar is one of the fastest growing sources of energy. This clean power source is readily available, without emissions or the need for traditional fossil fuels.
When incorporated into a hybrid microgrid, Cat advanced solar solutions help build resiliency with a renewable energy source. Converting sunlight into direct current to power microgrids, high-efficiency photovoltaic (PV) solar modules not only provide power during normal operations, but also feature technology to detect power disruptions and can operate in island mode.
Features and Benefits
Superior Performance – reliable and predictable energy in all climates and applications, particularly in high temperature, high humidity, extreme desert, and coastal environments.
Robust Modules – independently tested to pass accelerated life and stress tests beyond industry standards (including Thresher, IEC, ISO, UL, CSI, MCS, CEC, and other international standards) and come with warranty protection.
Scalable, Compatible, Easy to Install – a fully scalable, pre-engineered solar microgrid system.
Generate Savings and Economic Dispatch with EAAS
Energy as a service (EaaS) solutions combine an industry-leading technology platform with expert insights, managed services, and cutting-edge technology to significantly enhance the operational and economic opportunities of distributed generation and storage assets used in microgrids or hybrid energy solutions.
Utilizing EaaS can enable you to:

School District Integrates Traditional and Renewable Energy Sources for Resiliency and Savings
Cat® dealer Peterson Power Systems designed a hybrid microgrid for Portland Public Schools’ new world-class campus. Integrating photovoltaics and standby power generation and governed by a microgrid master controller, the microgrid system ensures secure power in the event of an outage and sends power back to the grid to reduce utility bills.

Cat® dealer Ziegler Power Systems engineered and designed a solar project for the Iowa Great Lakes Sanitary District’s wastewater treatment plant. The 500 kW direct current system supplies about 70 percent of the power demand at the wastewater treatment plant, saves the district $100,000 a year in energy costs, and offsets almost 500 metric tons of CO2 emissions annually.

The Chattanooga Metropolitan Airport installed a solar farm connected to a microgrid that includes energy storage, a Cat® G3412 gas generator set, and a control system as part of efforts to reduce the airport’s impact on the environment. The microgrid supplies power to the runway lights and other navigation aids at the airport and provides energy to an adjacent neighborhood since it’s tied into the local utility’s distribution system.
