KGDS Renewable Energy


KGDS Renewable Energy Private Limited, (KGDS) is a leader in research and development of Concentrated Solar Thermal Systems (CSP), Biomass power plant and Thermal Desalination technology since early 2008.

As evidenced by past accomplishments KGDS is into continuous research and development activities in a wide ranging spectrum of technological achievements in the renewable energy sector. Our focus is on solar, solar-biomass power production, desalination using agricultural output and agro-waste output.

Through continuous improvisation and investment we are committed to achieving reliable, world-class and cost-effective renewable energy based solutions in the area of solar thermal power and desalinated water from sea water. Our cherished goals are to develop these renewable and eco-friendly technologies in a scalable and replicable manner.

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.

Our patented technologies and world-class plant design enable us to generate green energy in a clean and cost-effective manner.

The Ministry of New and Renewable Energy has listed KGDS as an approved manufacturer / supplier of solar concentrating systems for steam cooking / process heat / cooling applications.

KGDS has been recognized as an in-house R&D unit by the Department of Scientific & Industrial Research under Ministry of Science & Technology, Government of India.

LFR Based Direct Steam Generating Solar Collector System

KGDS Renewable Energy has built a solar thermal research centre in Coimbatore with 1400 m2 of collection area.

This solar thermal system has been used to generate saturated steam up to 45 bar, 257o C directly from room temperature water.

This system has also produced direct super heated steam at 33 bar with 30o C of superheat.

Generation of 2 MW thermal at Delhi for MNRE in Aug. 2012

KGDS has been awarded a contract by IIT Bombay to build a concentrated solar thermal system in Gwalpahari, South of Delhi to produce 2 MWth dry saturated steam.

This will be part of generation and uploading to the grid of 1 MW of electrical power at the solar energy centre of the Ministry of New and Renewable Energy (MNRE)

Dairy Farming Process Steam

Pasteurization, dairy farming process steam, air-conditioning and refrigeration, agricultural drying, etc., are the types of industrial activities that can be carried out by the direct steam generation system we have produced.

These applications will enhance rural economy.

Solar Desalination Plant

Solar Thermal Desalination System in Ramanathapuram, Tamil Nadu

KGDS Renewable Energy Private Ltd. 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).

For a small rural community of Narippaiyur in Tamil Nadu with a population of 7500 people this system can provide the vital potable water requirement. This project has been commissioned on February 12, 2013.

Solar Biomass Hybrid Power Plant

In order to provide continuous power supply round the clock and in order to easily overcome variations in solar radiation during the day we are in the design stages of constructing a solar biomass hybrid power plant. An artist's view of the plant is shown on the left side.

Solar Biomass Power Plant Cum Desalination

Another plant in the design process is the solar biomass power plant cum desalination.

Here desalination takes place using the steam that is discharged from the turbine before it is condensed.

Because of the high productivity of the system the cost of electric power as well as the desalinated water will be quite competitive.
