Group Captive - In this model, a group of consumers forms a captive power company to collectively procure and manage their electricity needs. They may invest in their power generation assets or purchase power from a specific generator. Third-Party PPA - In the described scenario, a third-party investor or solar developer invests in an Open Access project and sells the generated power to corporate buyers through a Power Purchase Agreement (PPA). This arrangement allows the corporate buyer to avoid upfront investment and eliminates the responsibility for the operation and maintenance (O&M) of the solar project, which lies with the developer.
