• Network congestion in south
• Imported coal based generation has now came up in Kutch area.
• Almost no conventional generation in North
• Wind Generation in Saurashtra and Kutch only
• Solar generation in North
• Different category of load in different parts.
• 1600 KM coastal line causing pollution -Saline weather
• Extreme weather condition
• Aged assets
• Transmission losses below 4%

Smart Grid
What is Smart Grid?
A “smart grid” is an electric power delivery system from point of generation to point of consumption integrated with advanced communications and information technology. Integrated solutions and analysis tools to optimize resources & costs and enhance reliability and system efficiency.
Smart Grid
What is Smart Grid?
NEMA (National Electrical Manufacturer’s Association) defines Smart Grid as ‘the addition of monitoring, analysis, control and communication capabilities to the national electrical delivery system to maximize the throughput of the system while reducing energy consumption’
Definition
