Transgrid Overview

About Transgrid

Transgrid is the operator of the high-voltage electricity transmission network of New South Wales and the Australian Capital Territory, based in Sydney. The network was run by a state-owned entity until November 2015, when the New South Wales government granted a 99-year lease of the business to a consortium of Spark Infrastructure, the Utilities Trust of Australia, CDPQ, the Abu Dhabi Investment Authority and Wren House Infrastructure. Transgrid owns and operates lines, substations and interconnectors that carry bulk power from generators to distribution networks and neighbouring states, and its revenue is set by the Australian Energy Regulator. It is building new transmission links for renewable energy zones and the EnergyConnect interconnector. Ownership has since changed in several steps: OMERS bought a 19.99 percent stake from Wren House in 2020, the Future Fund took half of that holding in 2025, and GIC bought about 10 percent from the Utilities Trust of Australia in 2025.

DateStageInvestorsRaisedValuationDeal Summary
May 2025SecondaryFuture Fund--The Future Fund Board of Guardians, Australia's sovereign wealth fund, acquired a 9.995 percent interest in Transgrid from the Canadian pension investor OMERS in a transaction announced on May 20, 2025. OMERS retained a matching 9.995 percent holding and will manage the Future Fund's interest on its behalf, so it keeps its board seat and governance role in the asset. The parties did not disclose financial terms, and the transaction closed on announcement. It formed part of a reshuffle of Transgrid's owners during 2025, in which GIC separately agreed to buy about 10 percent from the Utilities Trust of Australia. Transgrid is the monopoly operator of the high-voltage electricity transmission network serving New South Wales and the Australian Capital Territory and is investing in new links for renewable generation. Its other owners include the Caisse de depot et placement du Quebec, the Utilities Trust of Australia, Tawreed Investments of the Abu Dhabi Investment Authority and Spark Infrastructure.
Apr 2025SecondaryGIC$639M$6.4BGIC, Singapore's sovereign wealth fund, agreed in April 2025 to buy about 10 percent of Transgrid from the Utilities Trust of Australia, which is managed by Morrison and Co, for roughly 1 billion Australian dollars. The sale completed in August 2025 and Infralogic data cited by ION Analytics put the price above 1 billion Australian dollars. The trust kept a holding of about 10.5 percent after the sale. It was part of a reshuffle of the owners of the New South Wales transmission network in 2025, in which the Future Fund separately bought 9.995 percent from OMERS and the Abu Dhabi Investment Authority, through Tawreed Investments, explored a sale of its roughly 19.9 percent holding. Transgrid owns and operates the high-voltage electricity network of New South Wales and the Australian Capital Territory and is building new links for renewable energy zones and the EnergyConnect interconnector. In May 2026 GIC was reported to be seeking a loan of about 650 million Australian dollars to refinance its stake.
Jul 2020SecondaryOMERS (lead)$1.4B$8.6BOMERS, the Canadian public-sector pension plan, acquired a 19.99 percent stake in TransGrid from Wren House Infrastructure Management, the London-based infrastructure arm of the Kuwait Investment Authority, in a deal announced on July 19, 2020. Wren House had been one of the five members of the consortium that leased the network from the New South Wales government in 2015 for about 10.3 billion Australian dollars. OMERS Infrastructure bought the holding after Spark Infrastructure and the other consortium members declined to take up their pre-emptive rights. The parties did not disclose the price, but press reports put the stake at more than 1.4 billion US dollars and valued TransGrid at nearly 8.4 billion US dollars including debt, equivalent to about 12 billion Australian dollars. TransGrid owns and operates the high-voltage transmission network of New South Wales and the Australian Capital Territory. OMERS, which managed 109 billion Canadian dollars of net assets, joined Spark, the Utilities Trust of Australia, the Caisse de depot et placement du Quebec and the Abu Dhabi Investment Authority as an owner.
