A microgrid is a local and independent energy system that operates connected to and synchronous with the traditional centralized electrical grid (macrogrid). It is essentially a scaled down version of the main grid that can operate both with the main grid or in island mode (off-grid). This allows the microgrid to be a fallback for structures or industries in the event of failure of the primary grid, or when the primary grid cannot supply sufficient power during peak times.
Microgrids come in a variety of designs and sizes and offer a more affordable and sustainable energy mix. Microgrids can operate using different sources of energy, allowing establishments to reduce their consumption rate of conventional power sources and amp up their renewable energy use.
The Sun Company chooses to work with greenfield development, focusing our Microgrids on previously undeveloped areas. Greenfield planning takes future growth and development into account, allowing us to avoid infrastructure issues that plague existing urban areas. This allows us to deliver the best possible solutions for our microgrids.
With a solar powered microgrid, there will be times when the resource (the sun) is not available. Due to this, The Sun Company's microgrids incorporate backup generators, which store and provide power to the microgrid when there is not sufficient production from the sun. The incorporation of a backup generator allows for a seamless switch between on-grid and island mode and ensures clean power is provided to the sensitive equipment at all times.
When the microgrid is connected to the traditional centralized electrical grid (macrogrid), it is considered an on-grid solution. When necessary and practical, it can switch between the two (on grid and island mode).
Microgrids that are never connected to the macrogrid are operating solely in island mode and are completely off-grid. Usually due to an economical issue or geographical location, island mode allows the system to operate autonomously.
Microgrids that are connected to the Macrogrid can switch to island mode and disconnect from the larger grid when necessary. This can be handled manually or in the case of power shortages and Macrogrid failure, automatically.
Microgrid as a service is a new, industry-leading mechanism that enables organizations to deploy microgrids without any upfront investment. This financing model allows for the stabilization of long-term energy costs and upgrade of critical energy infrastructure without capital outlay. The Microgrid as a Service business model allows us to solve many issues faced by large facilities, such as energy resiliency, infrastructure modernization, long-term stable energy cost and third-party maintenance, financing, ownership and operation.
