Global engineering, consultancy and advisory firm AESG has announced the acquisition of specialist energy consultancy The Energy Project (TEP). Alongside the acquisition, AESG has appointed Andrew Mather as Fractional Managing Director of its Australian business.

Andrew is a former national president of Consult Australia and received the prestigious Consult Australia President’s Award in 2023 for his four-decade industry contribution.

The acquisition of TEP adds renewable energy capabilities to AESG’s global sustainability and engineering portfolio. TEP advises on energy transition strategies and the development and delivery of distributed energy projects. The firm has worked with Stockland, Dexus, Charter Hall, Sydney and Adelaide Airports, Bunnings, Linfox and IKEA. TEP co-founder Patrick Greene will continue to play a leading role in the business within AESG.

Andrew will oversee AESG’s Australian business, including the integration of TEP. “AESG has built an impressive international consultancy by combining technical excellence with an entrepreneurial approach to growth. TEP is an excellent example of the type of specialist business that can make that platform even stronger,” he says.
