Cat microgrids integrate renewable power sources with generators, energy storage, and advanced control systems. Generator power makes the system resilient and reliable, but the ability to store and tap renewable energy means less generator use, higher efficiency, lower emissions, and lower fuel expense.
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.
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.

Solar, back-up generators, battery energy storage or the microgrid's other distributed energy sources then serve its customers until the grid's power is restored. A microgrid can be used to strengthen the broader electric grid by augmenting normal grid operations or easing the strain on the central grid during periods of peak demand.
When the price of utility power peaks under high demand, the microgrid can automatically switch your loads to on-site energy instead. If excess power is generated or stored on the microgrid, you can participate in demand response programs by selling energy to the utility, easing overall demand on the grid.
DERs are power resources outside a central grid, including microgrid generation and storage systems. A microgrid controller automatically connects and disconnects these from the macro grid by remotely opening or closing a circuit breaker or switch.
To do this seamlessly, the microgrid should be integrated with the utility's automation systems at the substation and distribution levels. By connecting a microgrid to the utility grid as a DER, you can help increase the role of renewables on the grid and improve grid resilience.
