Under this model, the customer pays for the solar power with a long term PPA with a set of investors. The investor sets up the solar plant either at the customer premises (captive) or at a different location and sells power to the customer ( IPP through open access). The terms of PPA is agreed upon between the investor and the customer. Auro builds the plant based on the investor requirements and maintains the plants. Auro also plays a key role bringing in the investor and customer together and execute the PPA.
