 Based on the provided search results, the Pinnapuram Integrated Renewable Energy Storage Project (IRESP) in Andhra Pradesh, developed by Greenko, includes a major Pumped Storage Project (PSP) component. While some reports mention Andritz as a supplier, the general project specifications indicate a high-capacity, off-river storage system

Here are the specifications for the Pinnapuram Pumped Storage Project (PSP):

1. Installed Capacity & Generation 

• Total Pumped Storage Capacity: 1,200 MW to 1,680 MW (Reports vary, with 1,200 MW often cited for Phase I and up to 1,680 MW in later documents).
• Units: The project features a combination of 200 MW and 100 MW vertical-axis reversible Francis-type units.
• Storage Capacity: 9,600 MWh to 10,800 MWh.
• Annual Energy Generation (Turbine Mode): ~2,774 MU.
• Annual Energy Consumption (Pump Mode): ~3,645 MU.
• Cycle Efficiency: ~76.10%. 

2. Technical and Site Specifications

• Type: Off-river, closed-loop system using two newly constructed reservoirs.
• Water Source: Initially filled from the Gorakallu Reservoir.
• Location: Pinnapuram village, Kurnool district, Andhra Pradesh.
• Reservoir Capacity: 1.3 TMC each (Upper and Lower).
• Pump Operation Duration: ~8.73 to 9.22 hours.
• Head: Rated head for turbine mode is 134.0 m to 119.27 m.
• Construction: Rock-fill embankments with a maximum height of 33-35 meters. 

3. Integrated Project Context (IRESP)

The Pinnapuram PSP is part of a larger 5+ GW integrated project: 

• Solar Power: 1,000 MW - 3,000 MW.
• Wind Power: 550 MW - 600 MW.
• Commissioning: Started in 2022, with major completion around 2025. 

Note: While Toshiba is a major player in hydro and pumped storage technologies in India, the specific results highlight Andritz for the electro-mechanical work at the Pinnapuram site.
