Energy in Smart Cities

Energy powers the Technologies which are the
foundations of Smart City.

Assuring 24X7 Power to all Smart Cities

Energy should be operated with completely
Smart Grid Technology.

24X7 Power in Smart Cities

Concept of UDC : Un-interrupted Limited DC

Decentralised Solar PV at Homes

DC wiring in every Home/complex of the smart city so
as to efficiently integrate the Solar PV directly

Usage of DC-powered Appliances like LED lights and
BLDC Fans.

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.

Can India’s 50% vehicles be Electric by 2030?

cost
Rationale

India does not have much oil



Mechanical
Drive-train
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

Electrical
Drive-train
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)
Recent

Year
Petrol cost
per Km
• Crosses each other and Gap increase year after year
• 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
