Abstract
This project report study examines solar thermal electricity generation technologies, undertakes a brief
analysis of those that could reasonably be considered suitable for commercial power generation for the
client, and identifies a preferred technology for further evaluation. The review and selection of a
preferred technology includes: (i) an assessment of the technology; (ii) consideration of the status of the
technology and commercial experience; (iii) consideration of the solar resource at the proposed
location; (iv) costs; and (v) risks.

BACKGROUND
The Client
Gammon Infrastructure Projects Limited ("GIPL") is an infrastructure project development company promoted by Gammon India
Limited, to participate in the development of infrastructure projects on a public private partnership ("PPP") basis. GIPL leads Gammon's
forays into development of infrastructure projects on PPP basis across sectors such as Roads & Expressways, Ports, Hydro Power, Urban
infrastructure, Airports, Special Economic Zones, Water and Wastewater management, Railways, Power Transmission lines, and
Agricultural Infrastructure. GIPL has also started undertaking projects in renewable energy sector. It has taken up biomass power projects
in Punjab and Haryana and Hydro Power Projects in the states of Himachal Pradesh and Sikkim. It now wants to enter into the area of solar
power and has assigned the job of preparing a project report on a 50 MW Solar Thermal Power Plant for suitable site in the country to the
consultants.
The Consultants
Pan Exergy Pvt. Ltd. (PEPL) is a leading Solar Technology Consultant and Turnkey Executor of upto 100kW Solar Projects. It has had a
significant expertise in Indian Solar Markets based on an experience of offering services to more than 600MW of Solar Projects in India.
Out of these 250MW are already under advanced stages of execution. For more details visit our website (www.exergy.in) of email us at
(info@exergy.in).
GIPL awarded PEPL the job for preparing a Project Report on a 50 MW Solar Thermal Power Project at a suitable site in the country.
PEPL hereby submits this report on 50 MW Solar Thermal Power Plant at Village Malar, Tehsil Phalodi, District Jodhpur in Rajasthan.
