ElectraNet is pleased to be connecting Epic Energy’s upcoming 100MW / 200MWh Battery Energy Storage System (BESS). This is another exciting development from our customer that is moving South Australia towards its net renewables target.

ElectraNet’s Business Development Manager, Claire Pickering, said, “Epic’s BESS will be located adjacent to our Mannum substation and their recently established solar farms.”

“The connection will involve extending an existing 132 kV busbar at Mannum substation to facilitate the cable connecting the BESS Facility.  We look forward to supporting Epic throughout construction of the project and the decades beyond as a valued connected customer of ElectraNet,” Claire said.

Epic Energy has been involved in the development of the Mannum BESS via development partner Recurrent Energy over the past two years and will be investing approximately $130 million in the project.

Epic Energy’s General Manager, Major Projects Delivery, Tom Forde, said, “Epic Energy was introduced to ElectraNet by development partner Recurrent Energy in mid-2023 for the purpose of negotiating the TCA. ElectraNet were responsive when negotiating this agreement, resulting in a seamless and on schedule process. They were also helpful when responding to queries along the way, which expedited the TCA.”

“Connecting BESS projects of this scale to the National Electricity Grid (NEM) is extremely complex, requiring a high degree of expertise, coordination, and collaboration between Electranet, Recurrent Energy and Epic Energy. ElectraNet continues to work alongside Epic Energy to navigate the technical challenges and connection process. We look forward to continuing this strong working relationship with ElectraNet during the future construction and operational phases of the project,” Tom said.

The Mannum BESS is proposing to use Canadian Solar and e-Storage’s proprietary SolBank battery solution, which is based on lithium iron phosphate (LFP) battery cells, which offers a high level of safety due to its integration of a top-tier active balancing battery management system (BMS) with the product’s thermal management system.

Tom said, “Epic Energy is excited about South Australia’s energy transition and is committed to leveraging our innovation and expertise in energy infrastructure to develop renewable energy projects that that support the clean energy transition.”

“Accordingly, we are investing in a portfolio of other renewable energy assets, with infrastructure ranging from wind and solar farms in regional parts of South Australia and across the country, to microgrids and standalone storage,’ Tom said.

Construction is due to start this year, with expected completion and energisation in the second half of 2025.
