Assessment of Climate Change Impacts on Wind Resources at Thimmapuram in Andhra Pradesh

How TERI helped Hero Wind Energy understand future wind patterns

We studied how climate change is affecting wind speeds at Hero Wind Energy’s wind farm in Thimmapuram, Andhra Pradesh and what it means for the coming years.

Client: Hero Wind Energy Pvt Ltd.

Location: Thimmapuram Village, Anantapur District

Project Year: 2024–2025

Project Overview

The Energy and Resources Institute (TERI) carried out a detailed study for Hero Wind Energy to check how climate change is impacting wind resources at their Thimmapuram wind farm.

Wind is the main fuel for wind power plants. Changes in climate can affect wind speed and reliability. This study helps Hero Wind Energy plan better for the future.

What we delivered:

30-year review of past wind patterns

Study of major climate influences (like El Niño)

Future wind forecasts up to 2040

Why This Study Was Needed

Wind power is clean and important for India’s green energy goals.

But climate change is slowly changing wind patterns across the country.

TERI’s study answers two simple questions:

How has wind speed changed in the last 30 years at Thimmapuram?

What will happen in the next 15 years (2025–2040)?

Key Findings (Easy to read)

Past 30 Years (1994–2023)

Average wind speed has been slowly decreasing since 2013.

Strong winds (good for power) are becoming less frequent.

Moderate winds are now more common.

Next 15 Years (2025–2040)

Wind speeds are expected to decrease slightly more.

This will have a small impact on power generation, but planning now will help keep the plant efficient.

Main Reason

Warming of the Indian Ocean is reducing the temperature difference between land and sea, which affects wind strength.

Benefits for Hero Wind Energy

Clear picture of how climate is affecting their wind farm

Better information for long-term planning and maintenance

Helps protect future power production and project returns

Supports India’s renewable energy targets.
