Product Manager- Power Generation

The Problem

Clarke Energy was appointed to build a power station in Central Queensland for a coal seam gas plant. In order to back up their power station, they required two generators to act as a prime power source during the construction of the station (which consisted of 10 x 3 MW gas engine generators sets once it was fully functional).

Objectives

Synchronised generators that will come into action whenever required, in the case of an outage.
Generators to be used on prime power for 6 months and be converted to stand-by black start solution afterward.
A controlled sound level, meeting Australian noise requirements.

Solution

CAPS engineered a solution, comprising two synchronised KX1100 Kohler generators equipped with MTU engines, which were also synchronised with the power station itself to enable it to restart in the case of a blackout.

A unique, customised control panel was installed, working to synchronise the two generators together and the plant at the same time.

The noise level had been reduced to 75 dBA (@ 7 metres) by using a super silent canopy, equipped with 50 mm sound foam and a residential exhaust silencer.

Benefits

Meeting the customer’s needs for a cost-effective solution, the generators effectively acted as a prime power source during their primary six months of use and also proved a strong backup solution thereafter.
