Established in 2005 and headquartered in Sydney, the group acquires and holds long-term interests in essential transmission and distribution businesses. It is structured to deliver stable, regulated returns by partnering with experienced local operators to oversee the performance, maintenance, and expansion of electricity networks.
The company’s core portfolio comprises significant stakes in SA Power Networks in South Australia, CitiPower and Powercor in Victoria, and the TransGrid transmission network serving New South Wales and the Australian Capital Territory. Through these investments, Spark Infrastructure participates in grid reliability initiatives, asset refurbishment programs and capacity upgrades, all under state and federal regulatory frameworks that govern tariff setting and performance obligations.

Governance is provided by an independent board of directors based in Sydney, which oversees strategic planning, regulatory compliance and stakeholder engagement. The group’s investment approach emphasizes strong risk management, operational collaboration and long-term value creation.
By operating across multiple regulatory jurisdictions, Spark Infrastructure achieves portfolio diversification while supporting Australia’s energy transition. In addition to its core electricity network holdings, the group evaluates emerging opportunities in areas such as grid-scale storage and smart network technologies, aligning its infrastructure investments with evolving market needs and sustainability objectives.
