A microgrid is a relatively independent localized power unit where distributed generation at the user's site can support electricity demand. To do this, your microgrid will access, monitor, predict and control your local distributed energy system, while strengthening the resilience of the power supply system to ensure that your electricity is more economical. You can use a microgrid while connected to the grid or disconnected from the grid. When the grid is out of service or the cost of electricity is too high, the microgrid will automatically respond.

Three main advantages of microgrids

• Achieve green and sustainable development by making full use of renewable energy sources such as solar and wind power on site.
• Save energy expenses by optimizing demand charges and smart charging and discharging management of energy storage.
• Improve reliability to ensure continuous power supply to loads during grid outages.

How does a microgrid work?

A microgrid control system enables comprehensive management and scheduling of power generation, storage and consumption. Unlike the power grid, which generates power at a centralized power plant and then transmits energy in a one-way manner along the generation-transmission-distribution-transformation-use path, a microgrid focuses on the distributed generation system at the user's site. For power generation, microgrids typically use a combination of renewable energy sources such as photovoltaics, diesel generators and wind turbines. Microgrids can be combined with energy storage systems to store electricity, and intelligent energy storage scheduling strategies can be used to charge and discharge electricity during power outages or peak grid demand.

Who can benefit from microgrids?

Today, microgrids and distributed energy are increasingly being used as an important part of the new power system to gain economic and sustainable benefits. We work with a variety of customers: from public utilities, commercial buildings to factories and campus construction. Microgrids can also be used in remote areas where the grid is difficult to reach or energy is scarce to provide much-needed resources. Anyone who wants to reduce energy costs, improve sustainability and increase power supply flexibility can benefit from microgrids.

How much does it cost to build a microgrid?

The architectural complexity and scale of microgrids vary depending on the actual situation. The ideal answer that companies expect is "free" because energy as a service (EaaS) solutions can offset the upfront costs. Microgrids can adopt more traditional investment and project delivery models. Under the project delivery model, the operating cost of microgrids is relatively low; under the Eaas model, the operating cost of microgrids is relatively high. EaaS is a typical financing model for microgrids, which can help you effectively save upfront costs. Similar to the SaaS model, EaaS can reduce upfront investment and only pay for energy services.
