Factors that drives for an adaptation of smart grid in India includes the need to reduce commercial & technical losses, resolve the chronic supply-demand gap & finding a revolutionize way for more advanced electricity supply leading to sustainability & high growth economic development goals. It provides real-time monitoring of data collection & remote control of system elements like, smart meters, intelligent devices, power lines, feeder switches, capacitor bank, fault analyzers & other facilities. The paper focus on (a) Current Indian Power Sector; (b) technology & devices used in smart grid; (c) Smart grid challenges; (d) current smart grid status in India. Key Words: Indian power sector, smart grid technologies in India, smart grids in India, challenges. 1.INTRODUCTION At present condition(in India) the grids are rapidly running up against its limitations slowly becoming a national challenge, the solution for this is smart grid, it is seeking attention of Central & State policy makers, Business persons & other powerful people, cause in a much less time a smart grid will function more efficiently, resulting in an expected power supply in more affordable price, along with leaving less impact in the environment. Smart Grid Pilot Projects in India is an initiative of Ministry of Power following certain objectives: (1) Increase in Power availability; (2) Reduction of AT&C losses; (3) Reduction in blackouts; (4) Managing load during peak hours; (5) Optimal Utilization of resources for sustainable growth. 1.1 Present power sector of India Indian company (Power Grid Corporation of India Limited) owns & operates about 1,34,018 cktkms of transmission lines at 800/765kV, 400kV, 220kV & 132kV EHVAC & +500kV HVDC levels and 214 sub- stations [8]. Also, the transformation capacity ofabout 2,78,862 MVA as on 31 st December 2016. This gigantic transmission network, spread over length and breadth of the country, is consistently maintained at an availability of over 99% [2]. The installed power station capacity in India as of June30, 2016 is shown in table1 [2]. According to the reports it has been observed that the Indian government encourages private producers to reach towards smart grid for a reliable power supply to the consumers end. The Indian power sector spreads in five regional grids to meet the demands, shown on table 2 [2]. These five regional grids are different in energy generation & in consumption. The institutions India Smart Grid Task Force (ISGF) & Indian Smart Grid Forum(ISGF) joined under Ministry of Power, India to set-up an institutional frame for deployment of smart grid projects in India [1,4]. The detailed overview of a smart grid is shown in figure1 & component technologies of smart grid is shown in figure2 [12].
