Grid Code Compliance

With the rapid expansion of renewable energy sources, distributed generation, and smart grid technologies, ensuring grid code compliance (GCC) is critical to maintain grid stability, reliability, and safety. At Intertek, we offer Grid Code Compliance Testing Services to help manufacturers, developers, and utility providers verify that their energy systems, including inverters, energy storage systems (ESS), generators, and grid-connected devices, meet regional and international grid code requirements.

What Is Grid Code Compliance?

Grid codes are technical requirements set by grid operators to regulate the connection and interaction of power-generating equipment with the electricity grid. These requirements ensure that systems can operate reliably, withstand faults, and support grid stability. Compliance with grid codes is crucial for equipment manufacturers and operators seeking to connect their devices to national or regional grids.

Our Grid Code Compliance Testing Solutions

At Intertek, we provide extensive grid code testing and certification services that cover:

Grid-Connected Inverters and Converters

With our deep expertise in more than 50 grid interconnection standards, we ensure that your inverters and converters meet grid interconnection requirements, including reactive power control, low-voltage ride-through (LVRT), and frequency response capabilities.

Energy Storage Systems (ESS)

Energy storage systems (ESS) play a crucial role in modern grids, balancing energy supply and demand. We provide comprehensive testing services for standards such as UL 1973, UL 9540, IEC 62933, and more, ensuring that your ESS devices meet performance, safety, and grid support requirements. This includes key functions like frequency regulation and peak shaving, with power conversion devices that comply with grid interconnection standards as part of the ESS.

Generator Compliance Testing

Generators, when connected to the grid, must meet the same interconnection standards as inverters and converters, with adjustments to requirements based on the specific technology. Our testing ensures that your generator systems can meet power quality, control, and protection criteria to successfully connect to and support the grid.

Global Market Access for Grid-Connected Products

In today’s interconnected energy markets, manufacturers of grid-connected products face a unique set of regulatory challenges. Ensuring compliance with both local and international grid codes is essential for the safe and efficient integration of equipment into power networks. Intertek’s Global Market Access (GMA) services streamline this process, helping manufacturers navigate the complex requirements for grid connectivity. From voltage, frequency, and protection settings to region-specific standards like IEEE 1547 in the U.S. or RFG in Europe, we provide the guidance needed to ensure your product meets the necessary regulatory and technical specifications, enabling faster, more efficient market entry.

Medium Voltage Switchgear and Transformers

Intertek also provides testing for transformers and medium voltage switchgear, essential for grid integration and energy distribution. Our services ensure compliance with performance, durability, and safety standards for efficient energy transmission.
