Longwarry energisation, another successful milestone for GRS


· The network support agreement was signed with AusNet Services to enhance the electricity distribution networks in Longwarry, Victoria

· The project has been carried out by GRS as the EPC contractor and E22 Energy Storage Solutions as the storage specialist

Madrid, October 20th – GRS, Gransolar group’s EPC contractor company, completed the construction on the Longwarry (Victoria) energy storage project, which was energised and connected to the grid this week, in another success of the company in Australia. This project is also an important milestone for E22 Energy Storage Solutions, Gransolar’s storage specialist subsidiary, that breaks ground installing the first lithium-ion battery in Australia, one of the world’s leading energy storage markets. The project has a capacity of 5MW/7.5 MWh and will provide support to the network service provider. 

As E22 Managing Director Jaime Vega explains, “We are very proud of what Longwarry means for E22 as a chance to enter the Australian market partnered with AusNet Services in this network service project.”

AusNet General Manager Network Strategy and Planning, Rod Jones, said: “This large battery energy storage system is one of the first of many across the AusNet network. In conjunction with Gransolar, the site will provide important network support capabilities for us over the peak summer periods and ensure a more reliable supply of electricity to our customers. It will also pave the way for more new and innovative solutions to the growing demand for energy services.”

Under the network support agreement signed with AusNet, E22 will make the battery´s capacity available during summer peak periods and other emergency events. Outside of the emergency dispatch periods, E22 will be allowed to participate in the electricity and ancillary services markets.

The Longwarry area experiences particularly high energy demand, especially during summer periods. When this storage project goes live it will improve the reliability of power supply in the community, helping to reduce power outages, among other benefits.

The connection of this project comes at a crucial time for the future of renewable energies in Australia, in the midst of a new direction set by the incoming Government, and a strong commitment on achieving net zero targets. 

Carlos López, Managing Director Australia at Gransolar Group, highlights the role energy storage will play in the development of renewable energies: “It is a time when large-scale projects are beginning to spread, often hybridized with renewables. These ambitious storage projects enable the transition to green energies by ensuring the energy supply, but also help correct grid imbalances and regulate electricity prices”.
