The EMS Off-Grid,
a solution designed for isolated and off-grid sites

Isolated Site & Microgrid,
what Are We Talking About?

When we talk about an isolated site, it can refer to an island, a mining site, or a remote village which is not connected to the national electrical grid of its country. Often, these isolated areas face difficulties accessing the electrical grid, either because connecting to the public grid is impossible due to accessibility issues or because it is too expensive compared to existing solutions. However, there is a solution to ensure access to electricity for the residents of these areas: a microgrid.

A microgrid is a small-scale electrical network that aggregates different energy production installations (e.g., photovoltaic panels, diesel generators, small-scale hydroelectricity, etc.), storage facilities (e.g., battery energy storage systems), consumption installations, and supervisory tools. This type of network has seen significant development thanks to smart grids, which enable more efficient and flexible energy management.

The development of a microgrid can address several needs. Firstly, it ensures reliable electrical supply, minimizes power outages, and prevents blackouts. The microgrid also helps reduce carbon emissions and energy costs while leveraging local renewable energy sources more effectively. In areas prone to natural disasters, these microgrids are capable of providing a source of energy even when the national grid is affected.

Microgrid: the essential role of EMS Off-grid

To address the challenges of these microgrids, deploying intelligent solutions such as EMS (or Energy Management Systems) is indispensable.

Acting as the conductor of a network, the EMS is an energy management software that can be deployed on sites with hybrid energy, particularly those equipped with battery energy storage systems. There are several types of EMS, depending on the use cases and equipment which are composing the site.

The EMS Off-grid is a type of EMS particularly suited to meet the needs of microgrids installed in isolated areas. Autonomous and intelligent, it manages all the equipment of a site (solar panels, wind turbines, generators, etc.), while integrating weather and electricity price forecasts. A valuable tool for optimizing the production and/or consumption of electricity for a site that is 100% disconnected from the national grid and ensuring continuity of electricity access.

Beyond optimization, Off-grid EMS proves to be a valuable ally as it allows for achieving several objectives:

• Balancing the network on an isolated site,
• Saving on electricity bills,
• Generating additional revenue through market valorization,
• Consuming green and local energy.
