SGSP (Australia) Assets Pty Ltd (referred to as SGSPAA), operating under the brand name Jemena, is an Australian enterprise responsible for owning and overseeing energy infrastructure throughout eastern Australia, including regions such as Queensland, New South Wales, Victoria, and the Northern Territory. Its holdings encompass both gas pipeline systems and electricity distribution networks. The company's ownership structure consists of a 60% share held by State Grid Corporation of China and 40% by Singapore Power.
History
The vertically integrated energy provider, the State Energy Commission of Western Australia, was divided in January 1995 into distinct gas and electricity entities, leading to the establishment of AlintaGas. Legislation passed in July 2000 facilitated the privatization of AlintaGas, which subsequently debuted on the Australian Stock Exchange in October 2000. On 8 May 2003, AlintaGas Ltd adopted the new name Alinta Limited. In October 2006, Alinta broadened its operations by acquiring infrastructure assets along with the Agility business from AGL through a combination of merger and demerger arrangements.
On 31 August 2007, a consortium led by Singapore Power International (SPI) together with investment firm Babcock & Brown successfully acquired Alinta for A$13.9 billion, surpassing a competing offer from Macquarie Bank. Following this takeover, eastern Australian assets were transferred to Alinta AGL, which was rebranded as Jemena on 4 August 2008. Ownership subsequently consolidated under Singapore Power International, resulting in a corporate name change to SPI (Australia) Assets Pty Ltd. In 2014, State Grid Corporation of China purchased a 60% interest in the company, triggering another rebranding to SGSP (Australia) Assets Pty Ltd (SGSPAA), while maintaining the Jemena trading name.
