 The Pinnapuram Integrated Renewable Energy Project (IREP), located in the Kurnool district of Andhra Pradesh, is a pioneering, world-first gigawatt-scale project developed by Greenko Group. It is designed to provide "Schedulable Power on Demand" (SPOD) by combining solar, wind, and pumped storage hydropower. 

Key Project Details (Pinnapuram IREP):

Total Capacity: Approx. 5,230 MW (comprising solar, wind, and storage).

Components: 3,000 MW Solar PV, 550 MW Wind, and 1,200 MW - 1,680 MW Pumped Storage Hydro Project (PSHP).

Developer: Greenko Group.

Status: Under construction/near completion, with major components aiming for operations in 2025–2026.

Features: It uses two reservoirs for pumped storage, with water sourced from the Gorakallu reservoir.

Purpose: To provide stable, dispatchable, renewable energy to the grid. 

Construction & Contractors:

Civil Works: MEIL (Megha Engineering & Infrastructures Limited) is executing the powerhouse, penstock tunnels, and pipelines.

Consultants/Contractors: RS Envirolink Technologies, Andritz, Freyssinet, Carpi Tech, Aarvee Associates, and Afry.

Progress: Unit #1 of the Pumped Storage Hydropower (PSHP) has achieved wet commissioning, and several units were commissioned in 2025–26. 

Significance:

It is considered the world’s first and largest integrated renewable energy project.

It aids in decarbonizing hard-to-abate industries.

It avoids 3.3 million tonnes of carbon emissions annually. 

Note: While some sources indicate 1,000 MW to 3,000 MW for solar, the overall Pinnapuram IREP project is part of a larger 5,230 MW ecosystem that includes surrounding solar/wind farms in the region.
