World’s longest underground high-voltage connection wins environmental award

Zurich, Switzerland, October 16, 2002 – A recently completed, high profile power project in Australia, using ABB technology, has been awarded a prestigious environmental award.

The Murraylink project — the world’s longest underground high-voltage interconnection at 177 kilometers — won the 2002 Case EARTH Award for Environmental Excellence for best practice and innovation in the environmental management of civil construction projects. The award was presented by the Civil Contractors Federation of Australia.

The underground interconnection, using ABB’s HVDC (high-voltage direct current) Light technology, won as a result of the environmental management and measures taken to minimize environmental impact during its construction.

The Murraylink project will transfer 220 MW of power between the states of Victoria and South Australia. Underground cable was chosen instead of overhead transmission lines to reduce visual and environmental impact, and to protect against Australia’s traditional causes of power outages such as lightning, wild life or bush fires.

Murraylink Transmission Company Pty., a subsidiary of TransEnergie, the transmission division of Hydro-Quebec, Canada, developed and operates the interconnection. ABB was responsible for the design, installation and commissioning of the HVDC Light transmission system, with the local contractor PIHA Pty Ltd carrying out the cable laying.
