SOLAR Power Plant pv Module (Renewable source of Energy)

With its abundance of sunlight, India has tremendous potential to emerge as one of the leaders in solar power generation. According to the Government of India s policy for the solar sector Jawaharlal Nehru National Solar Mission (JNNSM) a target of 20 GW of solar installations by 2022 has been set.

Global Scenario Solar Energy demand globally has been growing at about 30% per annum over the past 15 years. In comparison, the hydrocarbon demand growth rate is 0 2% per annum. This high growth rate in solar energy is due to many reasons increasing cost of petroleum products and the parallel decreasing cost of producing power from solar, and a concern world over on the harmful effects of using fossil fuels

Solar Energy in India India is one of the few countries in the world that has a dedicated ministry for New and Renewable energy In India, the high GDP growth rate has created a huge demand for energy, but the supply is unable to match the demand. The total installed capacity of power as of January 2012 is 187 GW. The per capita total consumption is 778 kwh. The estimated shortage of power in India is about 20 GW.

Why In India India is in the sunny regions of the world with most parts of the country receiving 4 7 kwh (kilowatt hour) of solar radiation per square meter per day, 250 300 sunny days in a year. Even though Solar energy constitutes a miniscule part in India s installed power generation capacity (with grid connected solar PV generation at a mere 6 MW as of March 2010), in the medium and long run, it is expected that solar energy, especially solar PV will form a vital component of the country's energy mix.

Incentives from Government

Jawaharlal Nehru National Solar Mission The Jawaharlal Nehru National Solar Mission (also known as the National Solar Mission) is a major initiative of the Government of India and State Governments to promote ecologically sustainable growth while addressing India s energy security challenges. It will also constitute a major contribution by India to the global effort to meet the challenges of climate change. Named for Jawaharlal Nehru, the Mission is one of the several initiatives that are part of National Action Plan on Climate Change. The program was officially inaugurated by Prime Minister of India, Manmohan Singh.

Scheme on financing of Off Grid and Decentralised Solar Applications Government of India, Ministry of New and Renewable Energy (MNRE) has formulated a scheme on financing of Off Grid and Decentralised Solar (Photovoltaic and Thermal) applications as part of the Jawaharlal Nehru National Solar Mission (JNNSM). Under the scheme, banks may extend subsidised loans to entrepreneurs at interest rates not exceeding five per cent where refinance of two per cent from Government of India is available.

Excise Duty Exemption on Transmission Equipments Exemption of Excise Duty on procurement of Transmission Equipments for initial setup of Solar Power Plant. The exemption would be available on transmission equipments wherever the contractual obligation for installing transmission lines/equipments up to the point of delivery is c0st on the solar power developer.

Subsidy in installation of Solar Power plant The Ministry of New and Renewable Energy (MNRE) provides 70 percent subsidy on the installation cost of a solar photovoltaic power plant in North East states and 30 percentage subsidy on other regions. The detailed outlay of the National Solar Mission highlights various targets set by the government to increase solar energy in the country's energy portfolio.

Major other incentives In the budget for 2010/11, the government has announced an allocation of US $ 220 million towards the Jawaharlal Nehru National Solar Mission. They encouraged private solar companies by reducing customs duty on solar panels by 5% and exempting excise duty on solar photovoltaic panels. The budget also proposed a coal tax of US$1 per metric ton on domestic and imported coal used for power generation. The government has initiated a Renewable Energy Certificate (REC) scheme, which is designed to drive investment in lowcarbon energy projects.

Opportunities and Challenges Land is a scarce resource in India and per capita land availability is low. Dedication of land area for exclusive installation of solar arrays might have to compete with other necessities that require land. The amount of land required for utility scale solar power plants currently approximately 1km 2 for every 20 60 megawatts (MW) generated could pose a strain on India's available land resource. The architecture more suitable for most of India would be a highly distributed set of individual rooftop power generation systems, all connected via a local grid. However, erecting such an infrastructure, which does not enjoy the economies of scale possible in mass, utility scale, solar panel deployment, needs the market price of solar technology deployment to substantially decline, so that it attracts the individual and average family size household consumer. That might be possible in the future, because PV is projected to continue its current cost reductions for the next decades and be able to compete with fossil fuel.

Solar Power Plant in Gujarat

Incentives from State Government Government of Gujarat declared comprehensive Solar Policy 2009, wherein Govt will purchase the power at the following minimum rates. for first 12 years for next 12 years from date of commissioning Solar PV Rs. 12/ kwh Rs. 3/ kwh Solar Thermal Rs. 9/ kwh Rs. 3/ kwh

Below 66 kv : Transmission charges, applicable to normal open access consumer and transmission and wheeling losses @ 10% of the energy fed to the grid, for Solar power Plant of capacity more than 5MW. For Solar power Plants of capacity less than 5 MW, Transmission charges, applicable to normal open access consumer and transmission and wheeling losses @ 7% of the energy fed to the grid.

Policy related to Land Acquisition for Solar Plant At 66kV : Transmission charges and transmission losses applicable to normal Open Access Consumer. Below 66 kv : Transmission charges, applicable to normal open access consumer and transmission and wheeling losses @ 10% of the energy fed to the grid, for Solar power Plant of capacity more than 5MW. For Solar power Plants of capacity less than 5 MW, Transmission charges, applicable to normal open access consumer and transmission and wheeling losses @ 7% of the energy fed to the grid.

Govt. s Initiative The Government of Gujarat is promoting Solar Power Parks in the Sate. Rolled Out Special Policy in 2009. Already few Plants are operational in the State. The development of solar parks will streamline the project development timeline by letting government agencies undertake land acquisition and necessary permits, and provide dedicated common infrastructure for setting up solar power generation plants largely in the private sector.. The State Government is taking initiative in providing the common infrastructure/ facilities like site preparation and leveling, power evacuation, availability of water, access roads, security and services. In parallel with the central government's initiative.

Contd. The Gujarat Electricity Regulatory Commission has announced feed in tariff to mainstream solar power generation which will be applied for solar power generation plants in the solar park. Gujarat Power Corporation Limited is the responsible agency for developing the solar park of 500 megawatts and will lease the lands to the project developers to generate solar power. Gujarat Energy Transmission Corporation Limited will develop the transmission evacuation from the identified interconnection points with the solar developer. This project is being supported, in part, by the Asian Development Bank
