TÜV Rheinland awards the automobile industry's first G99 grid code certification to Nissan Motor Co., Ltd.

- Promoting the connection of electric vehicles to the UK grid -

TÜV Rheinland has awarded G99 certification to Nissan Motor Co., Ltd., making Nissan the first automobile manufacturer to receive this grid code certification in the UK. This will enable the auto manufacturer to introduce Vehicle to Grid (V2G) technology, connecting its electric vehicles (EVs) to the power grid. This is a big step forward towards using renewable energy more efficiently, reducing electricity costs and achieving carbon neutrality.

V2G technology enables energy stored in EV batteries to be pushed back to the grid or into homes as needed, helping to reduce dependence on fossil fuels and bring about carbon neutrality.

The UK’s Grid Code G99 is a technical standard published by the Energy Networks Association (ENA) for regulating the connection of electricity generation equipment to the UK electricity distribution network (grid). It is a set of engineering recommendations created by the ENA and is required by law to be followed when connecting certain types of generation equipment to the electricity distribution network. This standard must also be observed when electric vehicles are connected to the electricity distribution network, in order to discharge the electric vehicle's energy onto the grid. TÜV Rheinland tested V2G technology for compliance with G99 and confirmed it was compliant before issuing the certificate for the technology.

The safety assessment of grid connections that link power grids with energy generation and storage systems is becoming increasingly important, as the use of renewable energy increases and the development of smart grids (next-generation power distribution networks) moves forward. Each country has its own requirements for similar regulations regarding connecting to power distribution networks.

TÜV Rheinland works with testing and certification experts in Japan and other countries to provide comprehensive compliance support services. These include verifying technical requirements for regulations and standards, helping with the conduct of preliminary tests, evaluating and reviewing the results of tests conducted by customers, conducting certification tests at our accredited testing laboratories, and issuing certificates.

TÜV Rheinland continues, in its role as a global third-party certification organization, to support efforts to bring about a sustainable energy society.
