Green engine for Eagle Street

Clarke Energy Australia has recently commissioned a 1 MW GE Jenbacher gas engine which is an integral component of the Trigeneration plant installed at One One One Eagle Street - a 44-level, premium-grade office development in Brisbane’s ‘Golden Triangle’ precinct. One One One Eagle Street has been designed to achieve a Premium Grade Rating through the Property Council of Australia and is targeting a world-leading 6 Star Green Star Rating and a 5 Star NABERS Energy Rating.

The 1 MWe high-efficiency GE Jenbacher gas engine will supply the building’s base electrical load with the hot water and exhaust gas recovered in a multistage absorption chiller to provide chilled water for the building’s air-conditioning system. The trigeneration system will also supply the building’s energy needs during grid power failures.

Trigeneration - also known as combined cooling, heating and power (CCHP) - has the ability to not only increase energy efficiency but also to reduce CO₂ emissions by up to 60% when compared with conventionally generated electricity . The gas engine by-product, waste heat, will further reduce the CO₂ emission of the building by reducing the requirement to operate conventional boilers and electrical chillers. By comparison, conventional electricity is generated by inefficient means which produce high CO₂ emissions and this, coupled with transmission losses, results in an inefficient source of energy.

Cogeneration/trigeneration has become a popular technology for high energy-intensive facilities such as office towers, hospitals, data centres, airports, shopping centres and industrial plants. In the building industry, when targeting Green Start Ratings and NABERS Ratings, most building complexes will engage cogeneration/trigeneration systems in order to achieve their energy-efficiency target and become more environmentally friendly facilities.

Clarke Energy Australia, as the exclusive distributor of GE Jenbacher gas engines, provides total gas-to-energy solutions ranging from the supply of gas engines through to the full turnkey delivery of gas-fired power stations and cogeneration/trigeneration plants from 300 kW to 60 MW.
