About us

We generate safe and reliable energy to power Australian homes and businesses.

Delta is a major Australian energy company, supplying safe and reliable electricity to power hundreds of thousands of Australian homes and businesses.

With a 1,320-megawatt operating capacity, we generate around 4% of the electricity used in the National Electricy Market (NEM), covering every State and Territory except Western Australia and Northern Territory.

Our operations are focused on supporting the energy system’s baseload needs, as Australia transitions to a more sustainable energy future. Our core asset portfolio includes Vale Point Power Station and Chain Valley Colliery, located on the NSW Central Coast. 

With decades of experience and a strong focus on responsible operations, we support energy security while actively investing in technologies and practices that improve the sustainability of our business. This includes a range of environmental and emissions-reduction initiatives, as well as the exploration of large-scale energy storage projects.

At Delta, our people, partners and suppliers are at the centre of everything we do, providing the insights and expertise to drive innovation and deliver future-focused outcomes across our operations. We are passionate about developing the next generation of energy professionals through our graduate and apprentice programs, supporting women in energy and promoting diversity and inclusion in our business.

We are also highly connected with the communities in which we operate, maintaining open consultation and supporting local initiatives that are making a real difference to people’s lives through meaningful community partnerships.

Delta is 100% owned by Sev.en Global Investments, a Czech-based family office investment group with a global portfolio focused on long-term opportunities in energy, mining, and related sectors. Sev.en’s investments include power generation assets in the UK and Australia, including the Millmerran and Callide power stations in Queensland and Delta Group in NSW.
