Energy on Smart Grid Technology Electricity usage, costs and control Manage huge volume of data Tools to help the consumers control their usage so they can lower their bills Management of the peak loads by reducing the demand Help consumers to manage their usage and power bills How much energy is needed and helps utility to lower the purchased power cost. Financial incentives to companies that reduce their load in response to a request. A smart city having a smart technology based grid should be provided with Ultra high speed internet, voice and video access to all the consumers, City wide Wi-Fi network for city and utility, Street light controls, Surveillance cameras. This will help to manage automatic outage and faults in an elegant manner. Energy Communication Interface unit . DC Powered Smart-city

Electric Vehicles in Smart Cities DC Powered Smart-city

Can India’s 50% vehicles be Electric by 2030? Year cost Mechanical Drive-train Electrical Drive-train Recent Rationale India does not have much oil Our oil imports rising continuously: hurts Indian economy No solution in site in short, medium or long-term Our cities and towns are highly congested Highly polluting urban India Cost of mechanical (IC Engine) drive-train (MDT) goes up year after year Electrical drive-train without batteries (EDT) cost goes down year after year (R&D, Moore’s law and SW) Crosses each other and Gap increase year after year Year cost Petrol cost per Km Battery + charge cost per Km Li-Ion Battery costs fall 8% per annum Cost of Fuel (Petrol) per Km increases every year Total cost of battery per Km (life-time depreciation, interest, maintenance and charging of battery) keeps coming down Crossed over recently and gap likely to only accelerate DC Powered Smart-city
