Bennett Clayton Trigeneration

Bennett Clayton Power at 76 Berry street

By Tina Perinotto

“9 November 2011 – The upgrade of Local Government Super’s building at 76 Berry Street, North Sydney, will take a 25-year-old building off the grid, no tenants disrupted, and it will outperform the new six star NABERS Energy rating.

And that’s just the start. In fact, this building outperforms on so many levels ­that calling it a game changer is almost understating its achievements.”

Fifth Estate Nov 2011

The Bennett Clayton system utilises multiple 100KW (max) engines that will come on line as required to match the energy demand of the building. This ensures that the building can operate on Trigen 24/7, independent of the grid.

Each engine is field serviceable, and will fit in a goods elevator for easy maintenance and replacement, while the remaining generators maintain supply

The generators are very fuel efficient, achieving a measured 50% plus electrical efficiency @ 80KW, and the emissions numbers are extremely impressive, including  particulates and NOx measurements.

The noise and vibration is very low, comfortably under standards for night residential operation.
