About Tresillian

Tresillian is a well-renowned organisation in Australia, dedicated to supporting and guiding new parents through the early stages of parenthood. Offering a wide range of services, such as residential programs, day services, and online resources, Tresillian seeks to alleviate the challenges faced by families during this critical time.

With a strong focus on the well-being of parents and their children, the organisation has become a trusted and essential part of the community.

How Zembl helped

Tresillian connected with Zembl through the Bulldogs in Business program. Zembl has proudly supported Bulldogs in Business members with their business energy needs since April 2024.

Tresillian partnered with Zembl to renew their commercial energy contract and advance their sustainability goals. Through our energy procurement service, Tresillian was able to secure competitive energy rates for their Wollstonecraft campus.

This resulted in $16,000 in savings over the duration of their new contract. These savings allow Tresillian to redirect funds toward their core mission of supporting families through clinical services.

Solar

Beyond energy savings, Zembl's energy efficiency service also facilitated Tresillian’s solar installation project in collaboration with our partner, Solar Choice. The project included expert industry guidance on system design, electrical safety, and the use of advanced optimisers to accommodate the specific needs of a healthcare setting.

Competitive quotes were evaluated, references were checked, and a recommended vendor was swiftly identified to ensure a fast and effective process.

We were pleased to assist Tresillian in securing a $19,686 STC rebate for their solar upgrade, with the 62.04 kW system expected to achieve a 3-4 year payback timeframe and deliver projected annual savings of $17,899.

Tresillian’s COO, Peter Hinrichsen, shared his perspective on the partnership's success, stating,

“The entire process was seamless, from the evaluation of the energy contract to the installation of the solar system. The financial benefits we’ve gained will allow us to continue focusing on providing high-quality clinical services to families.”

Zembl’s comprehensive energy solutions demonstrate our commitment to empowering organisations like Tresillian with meaningful energy transitions and cost-saving initiatives that support both operational efficiency and environmental sustainability.
