The Pinnapuram Greenko PSP (Pumped Storage Project) is a large-scale renewable energy project involving solar, wind, and pumped storage components

 The Pinnapuram Greenko PSP (Pumped Storage Project) is a large-scale renewable energy project involving solar, wind, and pumped storage components. Here's a chronological overview of its key activities:

Early Stages & Approvals:

Site Evaluation & Resource Assessment:

Greenko Group initially evaluated the Pinnapuram site for over a year, assessing wind and solar resources. 

Government Approvals:

The Andhra Pradesh government approved the project, including 1000 MW of solar, 550 MW of wind, and 1200 MW of standalone pumped storage capacity. 

Project Initiation:

The project was initiated with the intention of developing the pumped storage component. 

Environmental Clearance:

The project received necessary environmental clearances, including the submission of an EIA/EMP report and the establishment of a disaster management plan. 

Construction and Installation:

Reservoir Construction:

The project involves the construction of upper and lower reservoirs near Pinnapuram village. The lower reservoir will be filled from the Gorakallu balancing reservoir. 

Hydrological and Civil Works:

Megha Engineering & Infrastructure Limited (MEIL) was responsible for completing hydrological and other civil works, including the construction of the upper and lower reservoirs. 

ANDRITZ's Role:

ANDRITZ was contracted to install the turbine-generator units, with significant progress made on the installation of draft tubes and spiral cases. 

Unit Installation and Testing:

ANDRITZ achieved milestones such as the swift installation of all 8 draft tubes within four months and the completion of spiral case installation and pressure testing for all 8 units by December 2023. 

Commissioning Works:

ANDRITZ transitioned to the main unit installation and is preparing for the commissioning of the first unit, while also working on the remaining units. 

Future Developments:

Potential Capacity Enhancement:

The project has the potential to be enhanced in subsequent stages to 3000 MW of solar, 2000 MW of wind, and 2400 MW of standalone pumped storage. 

Grid Stability:

The pumped storage component is expected to lend stability to the grid by storing excess energy from renewable sources. 

Local Area Development:

Greenko is also involved in local area development initiatives, such as establishing a multi-specialty hospital, providing solar lights, and establishing computer labs and sports facilities in nearby schools.
