Energy Estate Unveils Major Subsea Cable and Data Center Plans for Tasmania
December 17, 2025
In a significant move to integrate renewable energy with digital infrastructure, Australian firm Energy Estate has announced ambitious plans to develop new subsea cable landing points and associated data center facilities in Tasmania. This initiative underscores a growing global trend where energy developers are leveraging their assets and expertise to support the power-hungry data center industry, particularly in regions rich in renewable resources.
The company, through its dedicated digital unit, is targeting the development of two major international cable systems with landing points on the island state. The CaliNewy cable is planned to connect from California, USA, landing at Bell Bay in Tasmania before linking to the Australian mainland. The IndoMaris cable would run from Oman and India, landing near Burnie, Tasmania. These projects aim to modernize Tasmania's connectivity, which currently relies on three submarine cables all over two decades old.
To support this digital expansion, Energy Estate this month signed a Memorandum of Understanding with the H2U Group to co-develop energy and infrastructure precincts in Tasmania, with an initial focus on the Bell Bay port area. These precincts are designed to host data centers and other energy-intensive industries, capitalizing on the region's potential for large-scale green hydrogen production. The Bell Bay hub is noted as the first of three Tasmanian sites the company is targeting.
While specific capacities and funding details for the cables and data centers were not disclosed, the scale of Energy Estate's broader vision is substantial. The firm, founded in 2018, has been involved in developing approximately 1.24 gigawatts of utility-scale renewable energy projects across Australia. Its strategy is to colocate data centers directly with its energy generation assets, a model it is actively pursuing across sites in Australia, New Zealand, and the United States.
Simon Currie, co-founder of Energy Estate, articulated the company's vision last year, stating, "Regions rising – this is what drives our team at Energy Estate. We are committed to delivering enduring regional economic growth and bringing data to the power represents an immediate and realisable opportunity for regional communities in Australia and New Zealand." He further noted that "Green data centers will be the anchor tenants for clean infrastructure and industrial estates – attracting manufacturing, renewable fuels, and other industries into our region."
The development signals a strategic push to position Tasmania as a key hub for sustainable digital infrastructure in the Asia-Pacific region. By directly linking green power sources with data centers and international connectivity, the projects could attract significant investment and high-tech industries to the state, while also providing a model for decarbonizing data-intensive operations.
