Rajasthan
largest amount of solar radiation
According to studies conducted by the US Department of Energy, Rajasthan
received the second largest amount of solar radiation in the world and Tamil
Nadu led India’s renewable energy efforts as over 30 per cent of the state’s energy came from renewable sources.
The National Thermal Power Corporation (NTPC), a public sector
company, has been selected to take the solar power mission of the country forward, keeping in mind
the prospects of tapping solar energy in a big way in states like Rajasthan and
Gujarat, said A K Singhal, Director (Finance), NTPC Limited. The Government of India, in its National Solar Plan, has envisaged at least
20,000 MW of solar power generation by 2020 and up to 200,000 MW by 2050.
Rajasthan supports
solar power generation
The Government of Rajasthan supports development of both solar thermal and solar
photovoltaic (SPV) power generation. To demonstrate and commercialize solar thermal technology in India, Ministry
of Non- Conventional Energy Sources (MNES) is promoting megawatt scale
projects such as the proposed solar thermal plant at Mathania in
Rajasthan. Government of India is encouraging private sector projects
through fiscal and promotional incentives for the renewable energy sector. Parallel efforts are underway in the area of solar PV
in which pilot-scale grid-connected solar PV power systems (25 KW to 100 KW) are under trial operations in addition to stand-alone projects in remote
unelectrified areas. In Rajasthan, the State Government plans to establish a Solar Energy Enterprises Zone
(SEEZ) in the districts of Barmer, Jaisalmer and Jodhpur by offering a package of incentives to private investors willing to develop various solar power technologies including solar thermal,
solar photovoltaics (SPV), solar chimney etc. An International solicitation
recently issued by Rajasthan has yielded two 50 MW solar PV power stations as well as one solar chimney project (200 MW) to be operated on an Independent Power Production
(IPP) basis.
Solar Power Project Mathania
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. |

National Solar Mission phase -1
Buoyed by the allocation of 873 megawatt to Rajasthan by the
Centre under the National Solar Mission phase -1 out of the 1100 mw, the
state is planning to develop four solar parks of 1,000 mw capacity with
a thrust on equipment manufacturing. Speaking at the solar energy session on the
first day of the Pravasi Bharatiya Divas -2012, chief minister Ashok
Gehlot said,"Solar parks of 1,000 mw capacity will be set up in Jodhpur,
Jaisalmer, Bikaner and Barmer. These enclaves will consist zones for
activities like manufacturing, research and development, and training."
He said 722 companies have so far registered for setting up of solar
power projects, with a cumulative capacity of 16,900 mw. Including the projects already
registered and the additional projects proposed, the sector is expected
to attract investments to the tune of Rs 16,000 crores, he added.
State, Clinton Foundation sign MoU on solar power
The Rajasthan government on 19 January 2010 signed a Memorandum of
