Location: Colac Water Reclamation Plant, VIC
Client: Barwon Water
Barwon Water’s Colac Water Reclamation Plant are utilising multiple 2G CHP units as well as additional 2G technology which use organic waste to produce electricity that is fed for internal consumption and back into the grid. Using this technology, enough energy is generated to be taken off the grid entirely and share outstanding energy.
- 2G 360kW Agenitor 408 CHP unit in a 9m x 3m x 3m
- 2G Gas Treatment System with cooling/reheating and activated carbon.
- 2G Avus 500 plus Biogas CHP
- C-Nox High temp flare
- TS Biological scrubber 3500ppm H2S >150ppm H2S
Enough electricity generated to power more than 1000 homes
Enough energy generated to offset the grid 100%
Contribute to Victorian Government’s water plan to achieve a target of net-zero emissions by 2050
Boost Victoria’s renewable energy capacity
Barwon Water’s Colac Water Reclamation Plant received 1 x 2G Agenitor 408 CHP & 1 x 2G Biogas Treatment and Conditioning System unit, as well as another 1 x 2G Avus 500 plus CHP as well as 1 x 2G Biogas Treatment and Conditioning System & a TS Biological Scrubber system that uses organic waste to produce electricity that is fed for internal consumption and back into the grid.
Using high-strength organic waste, enough electricity is produced equivalent to powering more than 1000 homes, allowing the Colac WRP to not only be taken off the grid but also to feed the grid with excess power and provide the plant and surrounding facilities with hot water, this considerably increases the efficiency of the plant.
By partnering with and utilising high-strength organic waste from the nearby Australian Lamb Company and Bulla Dairy Foods, the 2G Agenitor 408 CHP produces enough energy for the Colac WRP equivalent to powering over 1000 homes.
The immense amount of energy generated is enough to offset Colac WRP from the grid entirely. Excess energy that is generated is then shared back to the Australian Lamb Company in the form of hot water.
This project saw additional benefits such as a reduction in waste going to landfill, a boost to Victoria’s renewable energy capacity, driving down of energy prices and a reduction to greenhouse gas emissions.
The Victorian Government’s water plan aims to achieve a target of net-zero emissions by 2050. This project was a fantastic step by Barwon Water towards this goal. Barwon Water is well on their journey to adapting to climate change and ensuring that long-term environmentally conscious energy solutions are utilised.
A second-stage of the upgrades to the Colac WRP site saw the installation of up and downstream gas treatment, and a new 2G Avus 500 plus Biogas CHP generator to help the site cope with increased power demands.
Biogas to be used in the engines will now be treated with a TS biological scrubber, which ensures higher quality gas is being fed into the engines, reducing levels of H2S from 3500ppm to less than 150ppm.
A C-Nox flare was installed to ensure that any excess biogas that cannot be fed into the engines are safely flared off to reduce greenhouse gas emissions.
