Energy Vault, a global leader in sustainable energy storage solutions, has announced an agreement with Victorian government-owned renewable energy company, the State Electricity Commission (SEC) for the delivery and integration of a 100 MW/200 MWh battery energy storage system (BESS) at the SEC Renewable Energy Park – Horsham, Victoria. This hybrid solar and BESS project represents a significant step forward in supporting Victoria’s transition to renewable, reliable, and affordable energy.
The SEC Renewable Energy Park – Horsham is one of Australia’s first 100% publicly owned, utility-scale renewable energy projects. The project includes over 212,000 photovoltaic solar panels generating 119MW of solar power, capable of generating 242,000 MWh annually. Energy Vault’s integration of a grid-forming BESS will provide firm, dispatchable power to meet peak demand periods with a two-hour storage duration.
The $370 million investment by SEC will deliver enough renewable energy to power approximately 51,000 homes, creating approximately 246 jobs during construction and driving economic benefits for the Horsham region. Preconstruction works at the SEC Renewable Energy Park – Horsham began this week, and full operational status is expected to be achieved by late 2027.
The BESS system will be built with Energy Vault’s proprietary X-VAULT™ integration platform using the Company’s proprietary UL9540 certified B-VAULT™ product, and VaultOS™ Energy Management System to control, manage, and optimize the Hybrid BESS operations. Energy Vault’s innovative system architecture provides customer optionality with both battery and inverter suppliers, while unique AC-coupled and DC-coupled configurations provide the drop-in flexibility needed for any project.
Energy Vault CEO Robert Piconi expressed enthusiasm for expanding energy storage in Australia through a partnership with SEC on a hybrid project, marking the company’s first government collaboration. SEC CEO Chris Miller highlighted the project’s role in advancing Victoria’s renewable energy transition.
The announcement marks a key advancement of Energy Vault’s growing commercial footprint in the Australian market, following a series of recent agreements, including with Enervest and ACEN Australia for BESS deployments. To date, Energy Vault’s B-VAULT portfolio consists of more than 2 GWh in total projects either deployed or currently in development.
