Participants at the Site Visit could see how the landfill gas generator worked in conjunction with the traditional flaring systems traditionally used at landfill sites and how the system integrated with the BESS. The Bunya site still flared excess gas that could not be utilised for electricity generation due to export limitations to the grid Matthew Tapp explained how through LGI´s Dynamic Asset Control System (DACS), the energy generated and stored could be dispatched within seconds to the grid, providing benefits to the local community. Whilst the site provided environmental benefits by significantly reducing emissions from the landfill gas. The methane in the landfill gas is a 28 more potent greenhouse gas than CO2, so combusting it permanently destroys those emissions. Using the methane to generate and dispatch electricity during peak demand periods also provided significant benefits to the local distribution grid.
The Site Visit ended with a lengthy Q & A session followed by additional networking focused on the systems operations and interaction with the grid.
