Jemena

Jemena is an Australian energy infrastructure company. Jemena is a trading name of SGSP (Australia) Assets Pty Ltd (SGSPAA), jointly owned by State Grid Corporation of China and Singapore Power.

Jemena was formed as AlintaGas in January 1995 when the vertical monopolist energy supplier, the State Energy Commission of Western Australia, was disaggregated into separate gas and electricity corporations. On 13 July 2000 legislation was passed by the Government of Western Australia for the sale of AlintaGas which subsequently listed on the (ASX) on 17 October 2000.

On 8 May 2003 AlintaGas Ltd officially changed its name to Alinta Limited. The word alinta is derived from the word for fire in a traditional language of an Aboriginal tribe from Victoria.

Alinta acquired infrastructure assets and the Agility business from AGL through a combination of merger and demerger transactions on 25 October 2006.

The company was eventually acquired on 31 August 2007 by a consortium including Babcock & Brown funds and Singapore Power, the largest utility company in the city-state. after putting up a bid of A$13.9 billion, beating out a rival bid by Macquarie Bank. After acquisition, the Alinta businesses were split up. The majority of eastern assets were owned by an Alinta subsidiary which on 4 August 2008 changed name to Jemena, an Aboriginal word that means "to hear, listen and think". Later the company was wholly transferred to Singapore Power and its name was changed to SPI (Australia) Assets Pty Ltd.

In 2014 it was announced that State Grid Corporation of China had acquired a 60% stake in the utility, changing the parent company's name to SGSP (Australia) Assets Pty Ltd (SGSPAA).
