Navigating DNO Applications: Simplifying the Process

In the dynamic world of renewable energy, navigating the complexities of Distributed Network Operator (DNO) applications can be a challenging task. G59 Projects, a leading service provider, aims to ease the burden for clients seeking a professional, reliable, and cost-effective solution for their G99 DNO applications.

What are DNO Applications and Why Are They Necessary?

DNO applications are a crucial step in the process of connecting a renewable energy system to the grid. Distributed Network Operators, or DNOs, manage the distribution of electricity in specific regions. When integrating a renewable energy system, such as solar panels or battery storage, with the grid, it is essential to obtain approval from the DNO.

On a single-phase system, anything over 3.68 kW or 16 A per phase will require a G99 Application/ On a 3-phase system, anything over 3.68 kW per phase (11.04 kW total) also requires a DNO. This is regardless of what your intentions are regarding export. So even if you plan to limit your system to zero export you still have to apply as the DNO will be looking at what effects the generation will have on the local network.

DNO applications serve as a formal request to the DNO for grid connection, outlining the technical details, specifications, and compliance of the proposed project. These applications ensure that the new system aligns with the existing grid infrastructure, adheres to safety standards, and operates efficiently.
