Greenko’s business is designed to harness the opportunities in transition to sustainable development. Greenko is determined to take necessary steps and be a catalyst for change to protect planet, while improving People and Profits. Every function, more specifically project and asset management teams, contribute actively to caring for environment. Review of Greenko’s performance during the reporting period demonstrate that continuing efforts in minimizing use of resources and generation of waste. Further, Greenko contributes to conservation of terrestrial ecosystems at their sites, recharges and reuses water, conserves soil and natural drains. Greenko contributes to conservation of avi fauna and marine life in some parts of India. Going forward, Greenko has set short-term and long-term targets for protecting and enhancing the natural capital.

Greenko has set a target to make at least 85% of its critical suppliers certified by ISO 14001 and RoHS compliant by March 2020.


Strategic Approach

Greenko’s business is designed to catalyze the development in consonance with nature. Accordingly, it’s business inherently contributes to mitigation of harm to nature. In addition, Greenko is committed mitigate any negative impact on nature negatively across its operation and value chain to the extent possible. In addition, Greenko is proactively contributing to conservation of ecosystems and managing impact across life cycle of its power plants.

Journey so far

Greenko’s objective is to preserve and enhance nature throughout its value chain. Greenko is determined to take necessary steps and be a catalyst for change to protect Planet, while improving People and Profits. In this spirit, Greenko is steered towards contributing to the national issues and to ensure that the group’s activities respect, promote and advance internationally recognized environmental principles & commitments.

1 Mitigating Environmental Impacts

In pursuit of excellence, Greenko remains vigilant towards usage of natural resources and is responsible in reducing the impact on environment.

Greenko carries out Environmental and Social Impact Assessment (ESIA) study prior to the commencement of any operations, in line with the requirements of ten Equator Principles; eight International Finance Corporation (IFC) Social & Environmental Sustainability Performance Standards (PS); and IFC Environment, Health and Safety (EHS) Guidelines. All new projects developed by Greenko have undergone ESIA to pro- actively mitigate any issue that adversely impacts natural capital. All impact mitigation measures, which have arisen out of this voluntary ESIA, have been taken up for implementation.

Further, Greenko has implemented the following related initiatives:

1. ESMS implementation

2. ESMS training

3. Green Procurement

4. Preservation of Biodiversity


2 Adherance to Environmental Norms by Contractors and suppliers

To preserve and enhance nature throughout the value chain, the contractors and suppliers of Greenko also are required to adhere to environmental norms beyond compliance. This is achieved by Integration of environmental performance considerations in existing procurement processes. More than 50% of Greenko’s suppliers are certified for ISO 14001. Greenko’s SCM team is also creating awareness among vendors/ suppliers on environmentally preferred goods and services.

Greenko’s projects involve contractors who play a significant role during the construction stage. To involve them in preserving /conserving natural capital, the EPC contractors, OEM and civil contractors are required to sign and adhere to a Supplier Code of Conduct that incorporates measures to mitigate impact and preserve nature.


3 Contributing to Climate Mitigation

Greenko’s choices of energy generation helps in conserving the limited natural resources and consequent emissions, discharges and disposal. Further, it mitigates the GHG emissions and thus climate change by displacing fossil fuel. Greenko has avoided 8 million tons of CO2 by generation of clean energy. In addition, the group has till date registered 22 Clean Development Mechanism (CDM) projects with UNFCCC.

4 Managing Waste beyond Compliance

At Greenko operations, waste management is based on Environment and Social Management System. The ESMS requires conformance to legal requirements along with reducing the generation of wastes and to reuse or recycle whenever possible. The guidelines are followed for identification of the waste streams, their classification, manner of collection, transport and appropriate final disposal. Greenko carries out continuous monitoring of generation, storage and treatment/disposal of wastes by its contractors and vendors. Greenko conducts environmental education program for employees and partners, and finds it very effective in reducing, segregating, and managing waste.

The wind, solar and hydro projects do not consume any fuel for the power generation. Thus, the material consumption in these plants is only towards the O&M of plants.


5 Water Resource Management

Greenko owns and occupies sites of significant area through which natural drainages flow and water recharge and storage happens. Accordingly, whenever there is any modification in landscape at operational stage, Greenko ensures that the water resource system is not negatively impacted. Further, it makes the best efforts to restore traditional water resources as also ecological and water resource functions of landmass.

Water conservation measures have been implemented in all of Greenko plants. Rain Harvesting Pits, Storm Water Drainages and Rain Water Gutters have been constructed for conservation of water resource. In water-stressed regions rainwater harvesting has been implemented in the office and control room buildings. The water used for gardening is supplied by micro-irrigation (drip or sprinkler). Greenko ensured a substantial decrease in water consumption for Solar PV Modules cleaning activity with implementation of “MCS & Overhead Water Tank”. In a few Hydro Plants, arrangements have been made to divert and re-use of spillage water.


Watershed management at Kurnool

A water management program has been implemented in Ghani Solar Park, Kurnool, that promotes conservation of water by the construction of check dams and water canals around the operating site.

A total of 28 check dams and 12 kms long canal has been constructed in the solar park which assists in rain water catchment and the water is subsequently diverted into the reservoirs.

This water management program has resulted in better harvesting of the rainwater and its conservation by increasing the groundwater level in the region. This initiative has eventually benefited Greenko itself, the water that is required for the plant operation is procured from the improved water table instead of external sources

6 Energy Efficiency Initiatives

Greenko, across operations, practices energy conservation. Energy efficiency initiatives/ programs across our Greenko include

(i) use of CFL & LED lighting,

(ii) regular maintenance of the auxiliary equipment,

(iii) operational management of hydro plants- arresting water leakage through proper Grouting work in powerhouses avoiding the operation of pumps,

(iv) commissioning energy-efficient 5-star rated ACs and

(v) lighting controls automation with the installation of an outdoor light sensor timer.

7 Contributing to Biodiversity

Greenko takes proactive measures to restore, protect and enhance the biodiversity. Greenko has taken up a few bio-diversity conservation projects. The Fish stock seeding initiatives in the Netravathi river aims to protect the local ecology and bio diversity by fish stock seeding at its Hydel Plants on an annual basis. This program is undertaken in coordination with the Fisheries Department, Government of Karnataka. From the above initiative about 2,000 local fishermen residing nearby the reservoir are being benefited.

Other biodiversity protection programs taken are adoption of Rollapadu bird sanctuary for the conservation of the Great Indian Bustard, dientangling Ridley turtles and transplantation of the trees at project sites.

Some other significant initiatives taken are greenbelt development using micro-irrigation in our operating sites, bird nest development, drinking water holes for wild animals, fencing of water bodies near hydro plants to avoid accidents to animals, protection of tailrace sides with protective walls to avoid erosion in Hydro plants, fencing of HT lines/ transformers to avoid animal entry


Tree Transplantation

We have adopted the following steps during the process of transplantation.

1. Soil sampling and site selection

2. Root pruning and tree packing

3. Transplantation of trees

4. Mechanical support and root pruning

5. Post-transplantation treatment

Biodiversity enhancement at Rayala

At Greenko’s Rayala wind power site, an initiative to conserve and protect butterflies was undertaken. This is achieved by developing organic farm and plantation of high nectar flowers, Marie gold and Hibiscus, within the project boundary.

As a result of this program, the population of butterflies in the garden has increased. The vegetation in the site has also increased significantly. As an added advantage, organic vegetables from the garden are used in our sites’ cafeteria.

Project Disentangling Sea Turtles

Greenko has sponsored Project ‘Disentangling Sea Turtles’ with WWF India. The following progress is reported in 18-19.

Pilot surveys in Goa have been completed. All stakeholders including fishermen, life guards, officials from Forest and Fisheries’ Departments of the Government, are engaged

At Vizag , Dolphin Trawl Association and Fisheries and Forest Department of the government have been engaged and involved

Field team is put together and all preparations to undertake monitoring are completed. The activities of monitoring and conservation would begin after necessary permissions are obtained.
