Solar Power Project Mathania is about 30 Kms from Jodhpur. Solar radiation available in this regions is of the order of 6-6 .4 K wh/m2/ day which makes it a suitable location foe setting up of large Central Power Station based on Solar Energy. The Main objective of the project are
a) to demonstrate that operational viability of solar thermal power generation
b) support solar power technology development and
c) help reduce greenhouse gas (GHG) global emissions in the longer term.
This project has been envisaged as the first step in a long term programme for promoting solar thermal power in Rajasthan which would lead to development of similar systems in the country.
Description of Mathania Project
This project involves construction of an integrated Solar Combined Cycle (ISCC) plant with an average Solar yield of about 35 MW and a fossil field of maximum 3 times the solar field capacity, the total output of around 140 MW. It will be based on the integrated operation of the parabolic trough solar plant with a combined cycle gas turbine using fossil fuels such as Naphtha, fuel oil or low sulphur heavy stock (LSHS). The ISCC will operate as base load plant with and expected plant load factor of 80%.
The proposed project site is at Mathania near Jodhpur, Rajasthan located at 26.18' North Latitude, 73.01' longitude and 224 meter about MSL. In addition to high solar insulation levels, the proposed site involves
approximately 800.000 m2 of relatively level land with access to water resource and is in proximity to electric transmission facilities. The ISSC plant will comprise a solar field with a collection area of 219,000 m2 to support a 35 to 40
MW solar thermal plants) combined cycle power block involving two gas turbines each connected the Heat Recovery Steam Generator (HRSG) and a steam turbines connected to both
HRSG. ancillary facilities and plant services such as fire protection.
Naphtha/fuel oil/LSHS supply and storage system, and grid interconnection system, water supply and
storage system, and grid interconnection system, water supply and treatment systems, etc. A central building will have a central microprocessor control system that monitoring and controls all operations.
Rationale for the Project
The capital cost of solar thermal power generation technologies is 2.5 to 3 times more than fossil-based generation options resulting in a cost per unit of electricity higher than conventional power. The solar thermal
power generation option would, therefore, not dind policy and funding support if investment decisions were
based solely on traditional economic and financial criteria However, the potential role of solar technology in
mitigating GHG emissions and obviating other deleterious environmental effects associated with fossil fired plants is increasing
libeling recognized. Reduction of the high mitigating GHG emissions and obviating other being
recognized. Reduction of the high capital cost of solar power is required to move the technology closer of the economic mainstream.
Looking to the long range benefits. Global Environmental Facility (GEF) has decided to grant US $ 45 million to the project to party
neutralize the incremental cost of the project Government of India (GOI) has
also decided to sanction a grant of US $ 15 million and German Development and KW has agreed to
provide and load of DM 250 million for the project. For
the project GOR has agreed to provide balance required of funds as loan for the project which has been estimated to cost US $ 280 million. Demonstrating the solar plant's operational viability under Rajasthan's field conditions is expected to result in follow-up investment by the private sector in large solar station in Rajasthan Insight into local design and operating factors such as meteorological and grid conditions, and use of available back-up fuels, are expected to lead to its replicability, opening up avenues for large development of solar power plant with limited access to cheap competing fuels. Creation of demand for large scale production of solar facilities will in turn lead to reductions in costs of equipment supply and operation. It is also expected to revive and sustain the
international business and scientific community in improving systems designs and operations of solar thermal plants.
The operation of the solar plan is expected to avid emission of 64,000 tons/year of Carbon Dioxide compared to regular combined cycle operation, of 1.6 million tones during its lifetime. The cost of Carbon dioxide avoidance based on ISSCC operation is estimated at about US $ 13 per ton compared to US $ 34 ton if based on a conventional solar plant backed, up by a Ranking Cycle power block. These carbon Dioxide avoidance costs are competitive with other Carbon Dioxide avoidance technologies.
Moser Baer to set up India's largest grid connected Solar farm in Rajasthan
Moser Baer Photo Voltaic (MBPV), a wholly owned subsidiary of Moser Baer India,
announced on November 30, 2007 that it has signed a Memorandum of Understanding (MoU) with the
Government of Rajasthan for setting up of a large Solar Power Project in the
State with an estimated generation capacity of 1 ~ 5 MW. The project will be the
largest grid-connected solar farm in India and entail an investment of around
USD 25 million (Rs 100 crores) at USD 4.5 million per MW.
