Introduction:

With the increasing popularity of renewable energy sources, many homeowners and businesses are turning to solar panels as a sustainable and cost-effective solution. However, before you can connect your solar panels to the grid, you need to go through a specific application process with your Distribution Network Operator (DNO). In this blog post, we will delve into what a G98 application is and why it is essential for connecting solar panels to the grid.

What is a G98 Application?

A G98 application refers to the process of applying for permission from your DNO to connect small-scale embedded generators (SSEGs) such as solar photovoltaic (PV) systems or wind turbines. The term “G98” comes from Engineering Recommendation G98 issued by the Energy Networks Association in Great Britain.

Why is it Necessary?

The purpose of a G98 application is twofold: ensuring safety and maintaining grid stability. When connecting any form of electricity generation system, it’s crucial that safety standards are met. Additionally, DNOs need to manage power flows effectively within their networks to prevent overloading or voltage fluctuations.

Key Steps in the G98 Application Process:

  1. Initial Consultation: Contact your chosen DNO early on in your project’s planning phase. They will provide guidance on their specific requirements and any technical constraints that may affect your installation.
  2. System Design & Documentation: Prepare detailed plans including electrical diagrams, equipment specifications, protection settings, earthing arrangements, etc., as required by your DNO.
  3. Impact Assessment: Your DNO will assess how connecting your solar PV system might impact their network infrastructure and other users connected nearby.
  4. Protection Settings & Grid Compliance Testing: Ensure that all necessary protection devices are installed correctly according to industry standards outlined by Engineering Recommendation G99/2-1 or equivalent regulations applicable in other countries.
  5. Application Submission: Submit your completed G98 application form, along with all supporting documentation, to your DNO. Ensure that you have met all their requirements and guidelines.
  6. Approval & Connection: Once your DNO reviews and approves your application, they will provide a formal offer of connection. This offer will outline any necessary grid reinforcement works or modifications required for the connection.
  7. Commissioning & Testing: After completing the necessary grid reinforcement works (if any), you can proceed with commissioning and testing your solar PV system to ensure it operates safely and efficiently.

Conclusion:

The G98 application process is an essential step in connecting solar panels or other small-scale embedded generators to the grid safely and effectively. By adhering to the guidelines set by your DNO, you can ensure that both safety standards are met and grid stability is maintained throughout the installation process.

Remember, each DNO may have its own specific requirements for G98 applications, so it’s crucial to engage with them early on in your project planning phase. By doing so, you’ll be well-prepared to navigate through the process smoothly while reaping the benefits of clean energy generation from solar panels.
