Teralba Waste Coal Mine Gas Power Station

Capacity:	6 MW
Fuel Source:	Waste Coal Mine Gas (Methane)
Prime generator:	GE Jenbacher 320 Gas Engines

Teralba Power Station is located at Teralba Colliery near Newcastle in NSW. The power station and associated gas processing plant occupies a small area of approximately 20 x 50 metres and the siting of the power station is in close proximity to the mine’s existing vent stack which keeps the gas transfer system to a minimum. The power station is wholly located on the mining lease area.

Teralba is a closed mine and has been under care and maintenance for the last few years. As such the waste coal mine gas supply is declining. In the planning stage of the project, it was decided to install 8 generating units with a program to relocate units as the gas declined. In 2006 two units were relocated to Oaky Creek Power Station and in 2007 a further two units were relocated and installed at Oaky Creek Power Station. a further two units were relocated in 2007. The current capacity at Teralba is 4 MW and there is sufficient gas to maintain this capacity well into the future.

The power station consists of a gas transfer system to pick up the waste coal mine gas from the existing mine vent shaft. This system pipes gas to the suction pumps and gas processing plant, which are located in close proximity to the power station. At the gas processing plant the gas is filtered, compressed, and cooled before it is fed into a manifold system feeding each of six adjacent containerised 1MW gas engine units. The continuous flow of gas from the now closed mine enables the power station to generate on a 24 hour basis.

This power station was also supported by grants from the Australian Greenhouse Office.
