Grid Capacity is a web application that simulates the connection of renewable energy projects to the electricity distribution grid. It maps the hosting capacity of existing medium-voltage (MV) networks and identifies, in minutes, the possible connection solutions and the network extension and reinforcement each one requires, so developers can assess a site before submitting a formal connection request.

You locate your project on the map, enter its main characteristics (power, generation or consumption, voltage level), and run the simulation. Grid Capacity returns candidate connection solutions, each showing the length of network to extend and to reinforce. Every calculation assumption is visible and adjustable, for full transparency. Alternatively, you can explore the grid freely and design your own network upgrades.

A site is easier to connect when the nearby medium-voltage network has spare hosting capacity and needs little reinforcement. Grid Capacity quantifies this for a given location: the hosting capacity available, the possible connection solutions, and the kilometres of network to extend or reinforce for each. You can compare sites on a solid technical basis in minutes.

Hosting capacity is the amount of additional generation or consumption that a section of the electricity grid can accept without breaching voltage or current limits. Knowing it helps developers target favorable sites and avoid projects that would require extensive network reinforcement. Grid Capacity visualizes hosting capacity across existing distribution networks, and understanding the grid limitations.

Yes. Grid Capacity lets you run your own connection simulations, as many as you need, before contacting the Distribution System Operator. For each site you see the possible connection solutions and the network extension and reinforcement they require, which helps you prioritize projects and prepare a better-informed connection request.

Grid Capacity focuses on medium-voltage (MV) distribution networks, the level at which most utility-scale renewable projects connect. It models MV feeders, secondary substations, and primary substation hosting capacities.

Grid Capacity builds a digital twin of the distribution grid from open data and published network datasets. The exact sources depend on the country. In Brazil, it relies on ANEEL’s open distribution network database (BDGD), which provides detailed medium- and low-voltage network attributes.

Grid Capacity was developed and proven on the French distribution grid, one of the largest in Europe, where it has supported around 40 renewable energy developers. It is now available on request in every Brazilian state. If you work in another country where distribution grid open data is available, Roseau Technologies can assess adding coverage.

Grid Capacity is built for renewable energy project developers, independent power producers, and their advisors. It helps them prospect favorable areas, arbitrate between promising and risky sites on a technical basis, and optimize their connection requests to protect a project’s return on investment.

No. Grid Capacity provides independent technical assessments that help you plan and negotiate, but the Distribution System Operator remains the official authority on the connection offer. Because every assumption is transparent, Grid Capacity helps you understand and discuss the DSO’s proposals on a more balanced technical footing.
