The newly completed solar farm with 300 MW capacity is situated about 5 km northeast of Walla Walla in the Riverina region of NSW. The project involved the construction and operation of a new solar farm that connects to TransGrid’s Wagga Wagga to Jindera 330 kV transmission line, running near its western boundary. Changes made during construction included raising the maximum height of solar panels from 4m to 4.85m and increasing the height of substation transmission towers from 21m to 36m.

The Walla Walla Solar Farm will employ cutting-edge solar energy generation technology. It will feature ultra-absorbent solar panels equipped with anti-reflective coatings mounted on tracking systems that track the sun’s movement, optimizing sunlight capture for increased efficiency and output. The design and layout of the solar farm comply with local planning regulations and have been meticulously planned to mitigate environmental, cultural heritage, and community impact.

The scope of work under the contract includes but is not limited to design, supply, construction, installation, testing and commissioning, energising, and training staff in the operation of, a new 330/33kV substation, overhead 330kV transmission line, and OPGW/UGFC between TL62 and Walla Walla Substations.
