Most pumped storage hydropower in the world was built in the last century, at a time prior to the inclusion of variable generation in the electric power grid. However, in recent years, the nature of the grid has changed and variable generation through renewable power has increased and will continue to contribute a dominant share. Wind & Solar, are the lowest-cost sources of new energy, however, their inherent infirm & non-schedulable nature presents a huge challenge for integrating large RE capacities, while maintaining grid stability. The Integrated Renewable Energy Storage Project is expected to harness the power of solar and wind resources with digitally connected storage infrastructure to provide scheduled and flexible power to the grid. These provide the necessary scale (large volume of energy storage) and have a long-life cycle resulting in the lowest cost of delivered SPOD (Schedulable Power On-Demand) energy over the life of the projects.
The proposed Pinnapuram Integrated Renewable Energy Storage Project (IRESP) has been conceived as the World’s First & Largest Gigawatt Scale integrated project with solar, wind, and pumped storage components. The IRESP Project can meet the dynamic needs of DISCOMs/STUs, through:
The selection of machine i.e. variable speed or fixed speed can be done based on the requirement of the grid and the flexibility required for power generation or consumption. This flexibility positions us to harness some value pools in the electricity systems.
To execute this IRESP, we are working with very experienced global companies of repute such as Andritz Hydro, AFRY, Tata consulting Engineers, and EDF. To spot and partner with the best global resources and expertise, we have followed International Competitive Bidding and adhered to the guidelines of IFC. The systems and processes developed during this procurement are now standardized for deployment in upcoming projects. Further, our project management teams have designed the SOPs to address the challenges of balancing flexibility and robustness. Our partnerships with the vendors are executed in a twining mode, to learn from each other and to make the transfer smoother at the closure of the contract.
While we are designing and executing the project to harness all the possible value pools in the electricity systems, my colleagues are engaging with the government and contributing to public policy so that our electricity plus services are incentivized and thus sustained.
This milestone in our transformational journey of Greenko 3.0 and 4.0, will be achieved only with the active cooperation of all stakeholdersemployees, suppliers, regulators, public authorities, and communities. We call upon our stakeholders to actively engage with us for a successful joint endeavour to transform the electric system in India.
