KGDS Renewable Energy Pvt. Ltd., (KGDS) is a division of KG group. The KG Group is 70+ year old conglomerate of multiple business divisions with a rich and distinguished heritage based upon interests in information technology, business services, education, healthcare, textiles, finance, engineering, renewable energy and entertainment.

KGDS is a leader in research and development of Concentrated Solar Thermal Systems (CSP), Biomass power plant and Thermal Desalination technology since early 2008. Our focus is on solar, solar-biomass power production, desalination using agricultural output and agro-waste output. For the tropical and equatorial regions where solar radiation is intermittent our solar-biomass hybrid plant concept will suit for the combined generation of power and desalinated water.

On 13th August, 2009 Dr. A. P. J. Abdul Kalam, former President of India inaugurated our Solar Thermal Research Centre. Shri Deepak Gupta, then MNRE Secretary, and Dr. Ashvini Kumar, MNRE Solar Thermal Director, had also visited our research centre.

Solar Thermal Desalination System in Narippaiyur, Ramanathapuram District,Tamil Nadu,India

KGDS, in collaboration with NIOT has been awarded a project by the Department of Science and Technology, Government of India on August, 2010.

KGDS has developed an indigenous method of concentrating solar energy by the Linear Fresnel Reflector (LFR). Total solar collector area of the system is 1404 m2. On a hot day, the steam produced by solar energy will be used for desalinating the sea water by Multi Effect Distillation (MED) system. This system produces 6000 liters/hour of desalinated water.  

The total dissolved solid (TDS) in the desalinated water is less than 2 Parts Per Million(ppm). 

This project was commissioned on February, 2013.

Direct super-heated steam generating LFR system at Vallipuram, Kanchipuram District, Tamil Nadu, India.

The Centre for Industrial Consultancy and sponsored research, Indian Institute of Technology Madras had issued an order to KGDS to install a solar steam generating system with a capacity of 50 kWth at Vallipuram in Tamil Nadu.

The solar field size of the plant is 308 m2. The plant is intended to produce 0.16 TPH superheated steam at 50 bar 400°C. On a steady state condition, the project has achieved up to 500°C at 50 bar.

This project was commissioned on December, 2014.

Solar steam storage system at Vallipuram, Kanchipuram District, Tamil Nadu, India

Indian Institute of Technology Guwahati had issued an order to KGDS to install a thermal energy storage system at Vallipuram in Tamil Nadu. This was integrated with 50 kW LFR system installed at Vallipuram. The thermal energy storage system is sized for a storage capacity of 1.25 GJ.  

The main advantage of Concentrated Solar Power comes from its use of thermal storage to provide 'dispatchable' and on-demand energy from renewable energy sources. It ensures the reliability and cost-effectiveness of solar energy and provides a boost to the capacity utilization factor of solar energy plants.  

This project was commissioned on December, 2014.

Flue Gas-based Desalination for boiler feed water at NTPC Simhadri, Andhra Pradesh

The 120 TPD Flue Gas based Sea Water Desalination System (FGSW-Desal) has been successfully commissioned, tested at Simhadri Power Station of NTPC in the district of Visakhapatnam, Andhra Pradesh. The intent of FGSW-Desal system is to produce 120 TPD boiler quality De-mineralized (DM) water from sea water. It is accomplished by utilizing the thermal energy of waste flue gas of a fossil fired power plant to produce low pressure saturated steam which in turn is used in Multi Effect Distillation system to produce desalinated water from sea water.

This project has been commissioned on February 2017.
