2. A Rapidly Urbanizing World • For the first time in history, the proportion of world population living in urban areas reached 50% in 2008 • Will reach 60% in 2030 if present trend continues • Developed countries had attained 50% urbanization in 1950’s Developing countries will attain that level in a decade. • The least developed have most of their population in rural areas and will face the fastest urbanisation in the near future • Between 2007 and 2050 the world population growth will be 2.5 billion and the cities will absorb 3.1 billion • Urbanisation in developing countries not linked to economic growth, will happen even otherwise

4. The Challenges of Urbanisation • Populations in developing countries move to cities for better wages, amenities, health care and education • People prefer to be poor in city slums rather than in a remote rural area for better economic opportunities • Besides housing, this presents vast challenges of meeting energy demands of electricity, transportation and cooking fuels • Need to assure Energy Availability, Accessibility and Acceptability (3As) • In the context of developing countries 4Es are relevant - Energy, Environment, Efficiency and Equity • Challenge becomes greater on account of multilevel governance and financial jurisdiction-local, state and federal • Poverty and nascent democracy restrain harsh enforcement measures

5. Mega cities • In 1975 there were 179 cities with more than 1 million inhabitants. In 2007 they were 430 • Mega citiesdefined by UN as an urban conglomeration of more than 10 million, constitute only 4% of urban population • Mega cities are cultural, political and economic centres • Most visual part of the urbanising world depicting the advantages, disadvantages and disparities of life in a city • The biggest 30 cities produced 16% of the global GDP while accounting for only 4% of the population • Between 1975 and 2010 the number of people living in mega cities rose from 53.2 million to 318 million • In 1950 only two mega cities : Tokyo and New York. By 2025, there will be 27, and Asia will have 15 of them

6. Urban Energy Surge • World Energy Outlook 2008 : Cities consumed two thirds of global energy consumption in 2006, will consume three fourths by 2030 • Cities in transition move from traditional bio mass fuels to LPG and electricity as incomes rise • Mode of transport often determined by density and spread. • Metro services reduce oil consumption and pollution, but demand more and reliable electricity • Vertical rise of cities raises electricity demand for climate control (AC), water supply and lifts • However, mega cities often provide a better opportunity for innovation through better finances, political clout, media attention and visibility for federal support

7. CHARACTERISTICS and BURDENS of MEGA CITIES • Given their economic importance, each mega city must remain highly competitive in terms of infrastructure in a globalized economy • Serious energy constraints in developing countries made more acute in high demand mega cities • Climate change and local pollution concerns make capacity addition from conventional fuels more difficult • Business, transportation, high rise buildings, sensitive IT based information and communication system, traffic signals and large hospitals place a huge demand for electricity • The presence of ultra rich with energy intensive life styles adds to the demand

8. CHARACTERISTICS and BURDENS of MEGA CITIES Contd. • The integration of neighboring villages in extended limits of mega cities leads to pockets of lower quality electricity service • Energy poor settlements and erstwhile rural areas without an urban culture create serious problems of power theft and governance • Metro transportation has increased burden of secure and steady power • Working population leaving and returning home at the same time in a service oriented economy leads to peak demand • Space constraint for developing renewable energy infrastructure to meet renewable purchase obligations

9. CHARACTERISTICS and BURDENS of MEGA CITIES Contd. • Energy Demand Management becomes a critical issue to avoid disruptive black-outs and shortages • It is crucial and necessary to involve consumers in demand response management through differential tariff • Developed countries retro fitting smart grids • Danger of mega cities emerging in the developing world through sheer population size without modern logistics to ensure safe and secure electric supply Solution: We have to find a technology solution which minimises power demand, gives quality supply, is remotely controlled and involves participation of consumers. As life in a mega city is controlled by electricity the installation of Smart Grid is no longer a luxury or a brand idea. It has become a necessity.

10. DELHI : A MEGA CITY WITH CHALLENGES • From a small town of 0.4 million in early twentieth century Delhi is home to nearly 17 million people today • The National Capital Region NCR has a population of over 48 million • Highest per capita income in India • By 2012 population of Delhi 23 million NCR will be 64 million • 3.63 million households and an electricity consumer base of 3.33 million • Peak Power Demand met in 2004-05: 3490 MW in 2012 : 5600 MW • Aggregate Technical & Commercial Power loss in 2002 : 52% , 2011 : 18% Contd.

11. DELHI : A MEGA CITY WITH CHALLENGES Contd. • Vast improvement in distribution control system post Public Private Partnership in 2002 • Further reduction in losses hampered by some urban and rural pockets having high power and material theft and malpractices • Quality of power in villages poor on account of long distribution feeders • Regulator has imposed Renewable Power Purchase obligations. No local renewable source except solar. • Space constraint for any solar farm in congested urban area • Number of private vehicles has risen from 2.75 million in 1997-98 to 5.30 million in 2007-08 • Large scale introduction of Metro Rail Service to provide Mass Rapid Transport to decongest roads and reduce vehicle pollution has increased dependence on electricity.

13. YEARWISE STATUS OF AT&C LOSSES FOR PRIVATE DISTRIBUTION COMPANIES IN DELHI (IN PERCENTAGE) *AT & C Loss : Aggregate Technical and Commercial Loss.

14. MAKING DELHI SUSTAINABLE • Conserve scarce water through waste water recovery and rain water harvesting • Building Designs to be energy efficient • Solar reflecting roofs and water heating • Encourage Roof Top Solar power • Widespread use of CFL/LED lighting • Subsidised power tariff for low power consumption • Strong public campaign for consumer awareness to install energy efficient labeled appliances • Scrapping coal based thermal power stations Replaced with gas fired stations • Erect a world class Metro Rail network to substitute petrol/diesel driven vehicles. In 2012, Delhi Metro has 160 KM corridor carrying 2.2 million passengers daily with an average trip length of 15 Km By 2017 nearly 4 million passengers By 2021nearly 250 km corridor to carry 10.8 million passengers daily with an average trip length of 15 Km Issue : How to optimisepower demand and availability

15. POWER SECTOR MODERNISATION VITAL FOR DELHI • Delhi has become highly dependent on a secure and reliable power supply system without adequate generation of its own • Delhi is part of Northern Region (NR) which has met a peak demand of 40,000 MW this summer. Peaking shortage in NR has been 12-14% though Delhi has virtually no peaking shortage. • Delhi is part of an interconnected NR, WR, ER, NER grid of about 80,000 MW • Owing to over drawls and grid indiscipline by some constituents there were two successive grid collapses on 30th July and 31st July 2012 after almost 10 years leading to huge disruption for some hours • Large base load Coal Thermal Power means large off peak surplus. Need to curtail it through Smart Grid analytics and solutions • Distribution and Transmission networks need urgent modernisation and intelligent grids, as well as islanding of Delhi • Delhi being a national capital needs to immediately develop a smart grid to ensure safe supply, discipline consumers, optimise power requirement and improve quality of supply
