The company said it has supplied some 256 turbines since its first order in 2009, and it has received follow up orders under a periodical supply contract for the life of the Queensland CSG development project.

Capstone says it is the world's leading clean technology manufacturer of the microturbines.

“The coal seam gas market continues to develop as coal seam operators convert this gas into clean on-site power generation," Capstone CEO Darren Jamison said.

“It’s rewarding to see satisfied repeat customers continue to come back and add to their already large fleets of operating microturbines. In addition, Australia has been a key geographical focus for Capstone, similar to Latin America, Africa and the Middle East."

Optimal Group, Capstone’s Australian distributor, secured the latest follow-on order, which is scheduled to be commissioned in mid-2016.

"Optimal Group’s business in Australia continues to expand in oil and gas, coal seam gas and the combined heat and power markets,” Capstone's Jim Crouse said.

“In fact, they are currently our second largest distributor in terms of revenue generation over the trailing four quarters.

“I am confident that Australia will deliver substantial growth year-over-year and help offset slowdowns in other geographies,” he said.

CSG has developed into a major source of gas on the Australian east coast, meeting around one third of Queensland’s domestic gas needs, and supporting three LNG plans, with six trains in total.

The hungry LNG plants have been in development since 2009 and all have now started production.

Over 8600 microturbine systems are in use in the world.
