What is grid code certification?
Grid codes are technical rules and regulations governing the operation, maintenance, and development of electrical power grids. Essential for integrating various power generation types, such as renewable energy sources, they ensure supply reliability and security.
A grid code can vary by country and region as they are tailored to the specific characteristics of each power system. Grid code compliance is crucial to safeguard grid stability, avoid power interruptions through increased load, and ensure energy management efficiency. TÜV SÜD’s grid connection certification service is relevant to local grid codes and the requirements of grid operators in specific regions.

Why grid code testing is important
The development of power generation plants based on renewable energy sources is increasing, such as photovoltaics and wind power. The share of renewable energies in the overall energy balance will continue to grow in the coming years. Any unexpected demand can strain the grid. Non-compliant products may initiate grid faults or safety hazards, resulting in energy being wasted.
In Europe, grid code compliance is covered by EN 50549 – “Requirements for generating plants to be connected in parallel with distribution network”. There are also multiple standards across the world, both global standards and requirements specific to individual jurisdictions. Understanding the complexity of grid connection compliance is a challenge that manufacturers must face before they can sell their products.
Conducting comprehensive grid code testing improves product performance, meets regulatory requirements, and help you gain a competitive edge.

Frequently asked questions (FAQs)
What is a Power Generation Unit (PGU)?
A power generation unit is an individual system or apparatus that generates electrical power. It is a fundamental component within a larger power generating system or power plant. The PGU uses a pump, turbine, heater, and two heat exchangers. In this cycle, carbon dioxide is used to generate power.
What are Power Generating Systems (PGS)?
Power generating systems convert different forms of energy into electrical power to be distributed through the grid to end-users. They are generally treated as heat engines to convert heat input into energy to produce electricity at a sustained rate.
What products are affected by grid code?
Inverter, EV charger, on-board-charger, Energy Storage Systems and many more.
What are the relevant grid code standards?
