Microgrids

Effective Energy Management at the Local Level

A microgrid is a flexible energy solution that collects, stores, controls, integrates and manages energy supply and demand at the local level.

Microgrids: Connected to the Grid or Islanded

Flexible Energy Supply and Demand

A microgrid is a flexible energy solution that provides a range of power services.

A microgrid consists of loads, such as facilities, plants, and buildings, and distributed energy resources, for example solar, wind, and generators, that can be operated in a controlled, coordinated way, either connected to the main power grid or in “islanded mode” – allowing the microgrid to operate and provide power independently from the main power grid.

A microgrid can be an effective solution for peak shaving and demand response, as it allows for more efficient management of energy supply and demand at the local level.

Energy independence and resilience

Microgrids

A microgrid consists of three key components: (1) loads, such as facilities, plants, and buildings; (2) distributed energy resources, for example solar, wind, and generators, that can be operated in a controlled, coordinated way; and (3) a control system that intelligently integrates, manages and optimizes the operation of the microgrid. The result is reliable, resilient energy with the flexibility you need for energy independence.

What is a Microgrid?

A microgrid is a localized and independent energy system that can operate either in connection with or in isolation from the main electrical grid. It consists of distributed energy resources such as solar panels, wind turbines, energy storage systems (batteries), and can include small-scale generators. Microgrids also have their own digital control system that manages the flow of electricity, optimizes energy generation and consumption, and ensures grid stability.

Reducing the cost and environmental impact of energy production and consumption

How a microgrid uses renewable energy

Renewable energy sources – such as solar and wind – are ideal for microgrids because they provide a reliable and sustainable source of power. Renewable energy can be harnessed locally and does not require the transportation of fuel over long distances, reducing both the cost and environmental impact of energy generation and distribution. Additionally, renewable energy sources are often more predictable and consistent than traditional fossil fuel sources, which can be affected by weather conditions and supply chain disruptions.

Ensuring a more cost-efficient and reliable source of energy supply during peak demand

Energy storage systems

Energy storage systems, such as Battery Energy Storage Solutions (BESS), are another key component of a microgrid. An energy storage system captures and stores energy during periods until its needed (demand response) or when utility costs are at their highest (peak shaving). By storing excess energy, these systems ensure a more consistent and reliable energy supply during periods of high demand or when a renewable source is not actively generating power.

Local energy generation and storage

Distributed Energy Resources (DERs)

Distributed energy refers to the generation and storage of energy at or near the point of consumption, rather than relying solely on centralized power plants and transmission networks. It involves the use of smaller-scale energy resources that are located closer to where the energy is needed, providing a more localized and flexible approach to energy production.

Distributed energy enhances energy efficiency, reliability, and sustainability while reducing transmission losses and grid stress, and can include renewable energy systems, energy storage systems, and microgrids.
