ASREs operating income comes from the sale of electricity and/or thermal heat to customers in combination with different forms of subsidiaries per kWh. The goal is to in 2019 hold an installed capacity of around 230 megawatt (MW) that in 2020 is fully deployed and generates a current annual turnover of around 318 million RMB.
