A major transformation is underway at the Upper Sileru Power House in Andhra Pradesh, with the construction of a 1,350 MW pumped storage facility set to be completed by 2029. The facility will comprise nine reversible units of 150 MW each, effectively transforming the project into a grid-scale energy storage system.
The pumped storage system will store excess energy generated from renewable sources such as solar and wind during periods of surplus electricity availability, and release it back to the grid during peak demand. This will enhance grid stability, reduce energy wastage, and enable higher integration of renewable energy into the power network.
The Upper Sileru Power House, which currently houses a 240 MW hydroelectric power generation facility, is one of the oldest and most reliable hydroelectric stations in the southern state. The facility has consistently met its performance targets, with an annual energy generation potential of approximately 575 million units.
The construction of the pumped storage facility will significantly strengthen Andhra Pradesh's energy infrastructure, improving peak load management and supporting the state's transition towards a cleaner and more sustainable energy future.
