Sigenergy V2G Approved for use on Essential Electricity network in NSW

Essential Energy, CSIRO, Sigenergy, and AUSEV announced today that vehicle-to-grid (V2G) technology is now market-ready in Australia. The announcement came during the Smart Energy Conference in Sydney on April 9.

After conducting trials with the Nissan Leaf using CHAdeMO charging technology, Essential Energy has successfully connected AUSEV's Ford F-150 Lightning with a combined charging system (CCS2) DC bi-directional charger and the Sigenergy storage system, which has received Clean Energy Council approval.

Zecar has confirmed with Essential Energy that the V2G module of the Sigenergy storage system has only been approved on their network with the AUSEV Ford F-150 Lightning.

Essential Energy and CSIRO are currently exploring V2G technology with other EV manufacturers to provide additional options for customers.

The Sigenergy SigenStor energy storage system with integrated V2G charger can be installed on the Essential Energy network through the existing solar connection process.

Luke Jenner, Chief Operating Officer at Essential Energy, described the achievement as a huge step forward in enabling the energy transition.

"V2G unlocks the potential for customers to get more value out of their renewable energy investments and is a critical step in facilitating the uptake of electric vehicles," Jenner stated.

The company has been testing V2G technology on its network since 2023, beginning with a customer's Nissan Leaf and Wallbox Quasar charger.

Essential Energy partnered with CSIRO to research V2G technology as part of a home electricity management system and to understand its integration potential with buildings and the electricity grid.

Last year, they began additional trials at Essential Energy's Innovation Hub in Port Macquarie.

Dr. Sam Behrens, CSIRO Project Leader, called this development "a key transition step in supporting rooftop solar and grid stability in Australia."

He noted that the successful demonstration of a CCS2 bi-directional charger with a market-available V2G-capable vehicle opens the path for wider adoption of CCS2-compatible V2G technology.

Will Hall, Sigenergy Managing Director for Australia and New Zealand, expressed pride in the partnership, stating that the company is "pushing the boundaries of energy flexibility and unlocking new possibilities for a smarter, more resilient grid."

Essential Energy utilized its own F-150 Lightning, part of its fleet transition, to test the bi-directional charger at its Innovation Hub. Edward Kocwa, AUSEV Chief Executive Officer, described the benefits of V2G for customers as "a game-changer for the industry."

"Not only will customers be able to use the F-150 Lightning as a work ute, it will now essentially turn the vehicle into a mobile battery pack," Kocwa explained, noting that the vehicle's large 131kWh battery can power homes and small buildings for extended periods during power outages.
