Managing a project across its lifecycle

We conceptualise all our projects based on the principles of environmental compliance, resource optimisation, waste minimisation and long-term sustainability. To establish renewable energy projects, we follow a well-defined due diligence process.

After completing the due diligence, the project enters the engineering and construction phase, which strictly adheres to relevant regulations and ensures compliance. Periodic monitoring serves as a crucial management tool for tracking organisational progress, facilitating decision-making, and supporting sustainability reporting. Environmental monitoring ensures:

  • Regulatory compliance
  • Protecting the natural resources in and around its operations
  • Proactive management of impacts and avoidance of risks
  • Avoid environmental degradation through robust mechanism
  • Ascertain the environmental and social risks relevant to the operations

Additionally, we adopt a proactive approach, anticipating potential risks and mitigating environmental hazards to minimise risks and ensure a safer environment. Our objectives include:

  • Striving to go beyond regulatory standards, wherever possible
  • Improving efficiency, minimising waste and conserving resource across all operations
  • Inculcating sustainability values in employees through sustainability training
  • Creating awareness on environmental and sustainability issues through various stakeholder engagements
  • Reducing individual carbon footprint through awareness

At the end of a project, the decommissioning is also carried out in accordance with applicable regulations and procedures as established by the law.

ESG data management system

In the short term, we plan to establish a comprehensive ESG data management system. This system aims to efficiently gather the necessary ESG data from all our clusters, divisions and offices. Additionally, we aim to incorporate ESG data analysis into our reporting process, ensuring compliance with internal and external data requirements on platforms like BRSR, CDP, and DJSI, among others. Once such a system is implemented, it will benefit in the following ways:

  • Ease in collection and availability of all business, plant and location-wise ESG data, thus resulting in better ESG-performance monitoring
  • Streamlined reporting, data analysis and adherence to global and Indian sustainability standards
  • Regular peer benchmarking which gives insights into the best industry practices
