SECTION 1-: INVITATION OF BIDS

India has a very good solar energy potential of around 5-7kWh/m2/day. A significant part of India’s low-medium temperature process heat need can be met by concentrating solar heat (CSH) technology systems –alongside process integrating and suitable heat storage. This would reduce global CO2 emissions, air pollution, and India’s growing dependence on expensive and insecure imported oil. The abundant solar radiation, clean character of solar energy, high cost of fossil fuels and negative emission consequences along with large requirements for process heat below 250°C are the key drivers of the strong focus on the development of solar thermal applications in India. The use of solar concentrator to meet the process heat requirement of industrial and commercial establishments is an emerging and exciting market opportunity in India. The Ministry of New and Renewable Energy is implementing a National Programme on Solar Thermal aimed at peak shaving, conservation of electricity and fossil fuels and providing a clean, non-polluting solution to meet the process heat requirement in industrial sectors. Various promotional incentives in the form of capital subsidy or soft loan are available for solar concentrator projects under the Jawaharlal Nehru National Solar Mission (JNNSM). The web-site of the Ministry www.mnre.gov.in may be visited for information about the National Programme and the Guidelines for Off-Grid and Decentralized Solar Applications under JNNSM. To boost the use of Concentrating Solar Technologies, the Ministry is also implementing a new UNDP-GEF supported project on “Market Development & Promotion of Solar Concentrator based Process Heat Applications in India”. The objective of the project is to promote and commercialize Concentrating Solar Technologies for industrial process heat applications in India and facilitating the installation of 45,000 m2 of installed solar collector area by March 2017 through demonstration and replicated projects. Direct emission reduction from these projects during its 5 years period will be 39,200 tonnes of CO2. A total of around 160 systems have been installed so far in the country with a cumulative figure of 32,000 sq. m. of dish area. Many more are under installation. 4. Proposals are invited under the UNDP/GEF CSH project for “Collection & Compilation of data on CST based systems through remote monitoring using SIM based data loggers in the field as regards to their performance on heat delivery, fuel savings and GHG abatement” as per below:

TERMS OF REFERENCE

SECTION – 2: TERMS OF REFERENCE

2.1 Introduction

The industrial & commercial sector is the second largest energy using in India after the residential sector. It is estimated that of the total fuel consumption in India, 15 to 20% is consumed by industries for low & medium heat processes ranging from 600C to 2500C. The heat requirement is met by burning conventional fuels such as coal, furnace oil, natural gas and electricity. Use of solar concentrator technology integrated with system process heat demand can help replace/reduce conventional fuels which in turn will help reduce GHG emissions. Five sectors are identified for the demonstration of the technology i.e. dairy, textiles processing, hospitals, chemical processing and institutions which require process heat at high temperature and are sectors that constitute a significant share of the small scale enterprise.

In India 4 types of concentrating solar technologies are presently in promotion for the purpose of process heat applications. These are i) Fixed focus E-W automatically tracked elliptical dishes ii) Single axis tracked parabolic trough concentrators & Linear Fresnel Reflectors iii) Dual axis fully tracked paraboloid/ Fresnel Reflector based dishes and iv) Non-Imaging Concentrators

For promotion of these technologies, support upto 30% of the system cost subject to certain benchmarks is available under off-grid scheme of JNNSM. Higher support of 60% is available in special category states. In addition 15% of the MNRE benchmark cost is available under UNDP-GEF CSH project for specific activities related to performance monitoring, preparation of DPR/ PFR and Operation & Maintenance of systems. The systems are being installed through State Nodal Agencies/ accredited private channel partners as per technical specifications laid down by MNRE. A total of over 160 systems have been installed so far in the country with a cumulative figure of 32,000 sq. m. of dish area. Many more are under installation. There are 19 manufacturers/suppliers of such systems whose list is available at MNRE website www.mnre.gov.in/ www.cshindia.in

Through this assignment, it is proposed to collect & compile data from the installed CST based systems in the field for assessing their performance on heat delivery, fuel savings and GHG abatement for the purpose of seeing the utility of systems and taking suitable measures on improving the quality of these technologies in the country.

2.2 Objective
