AES operation of client plants results in a reduced carbon footprint due to efficiency gains and this reduction in carbon footprint can be furthered through consideration of a fuel switch to lower carbon fuel types such as biomass, biogas and natural gas. AES has previous project and operational experience on numerous alternate fuel plants including a biomass power generation facility with a 6 MWe installed capacity. The activities by AES for greening of energy plant operations have covered biomass to steam, biomass to power, by-product repurposing (e.g. sugar waste to energy or biodiesel production) and waste energy / gas utilisation (power and thermal).
