MR. ASHOK SETHI COO & EXECUTIVE DIRECTOR, TATA POWER Indian Power Sector & The Smart Cities Project It has been estimated that the urban population in the country would almost double from 2014 to 2050. The power sector will play a huge role in ensuring that the challenges being presented by India’s unprecedented growth are met. According to the United Nations, India is all set to become the world’s most-populous country by 2022, overtaking China. Estimates suggest that about 25-30 people will migrate every minute to major Indian cities from rural areas in search of a better livelihood and an enhanced lifestyle. With increasing urbanization, urban areas are expected to house 40% of India’s population by 2030. In order to accommodate this massive urbanization, India needs to find smarter and more efficient ways to manage its resources. Prime Minister Narendra Modi’s pet project, the Smart Cities mission, takes into consideration India’s need for efficient and “smart” urbanization. The Smart Cities mission is essentially an urban renewal and retrofitting programme with a mission to develop 100 cities which are citizen friendly and sustainable across the country. It recognizes the fact that cities are engines of growth of the Indian economy with more than 60% contribution to India’s GDP. Urban areas are expected to contribute about 75% of India’s GDP by 2030 and in order to facilitate the same comprehensive development of physical, institutional, social and economic infrastructure is required. Smart Cities in India Even though the government hasn’t prescribed any particular model for a smart city, it is expected that the smart cities will include a large number of infrastructure services and smart solutions. In particular, the elements that must form part of a smart city are assured electricity supply with at least 10% of the Smart City’s energy requirement coming from solar and smart metering. In the case of redevelopment and Greenfield models of Smart Cities, at least 80% buildings should be energy efficient and green buildings. Integrating smart grid solutions Incorporation of the smart grid technology in the smart cities project will offer a unique opportunity to jump into an improved electricity environment and provide reliable 24X7 electricity to consumers. Through smart grids it will be possible to integrate the coal and crude oil generated electricity with the solar and wind. This will reduce fossil fuel use and encourage price drops in renewable technology. Further, current smart grids are also building the technology to integrate consumer-owned energy systems which will benefit customers further – they will not have to pay for the electricity generated by themselves. Smart grids can also monitor loading thus avoiding load shedding and blackouts. Moreover adopting the ‘islanding’ technique will help ensure that Indian cities get uninterrupted supply of power. Islanding which refers to a condition in which a source continues to get power in a location even when the electricity from the grid is not amenable to being continued due to disturbance in such system, which infact, if allowed to remain connected under such situations, could lead to distribution system itself go-down & sulk/sink along with interconnected grid. So, islanding helps the distribution network bid itself to get absolutely isolated to a harms-away situation from the adjoining grid interconnections. This is used to simulate the said area is an island with no other system existing besides its own elements of Power Generation, Transmission and Distribution, which work in perfect harmony and let the consumer not feel any interruption or change of state, where a lot serious activity is happening in the adjunct systems outside of this island. Innovations for combating space constraint like pole mounted transformers, natural ester-filled transformers, underground feeder pillars, e-house DSS and using indigenously designed outdoor meter panel box for societies will help setting up the infrastructures where alternative spaces are not available. Demand Side Management will form an essential part to manage the load. Technologies like Thermal Energy Storage Technology’ will in shifting load from peak to off peak hours by using practical, financially viable and proven technologies. With the use of ‘Thermal Energy Storage Technology’ the central AC plants can run in the night and convert water in the form of ice. During day-time, the AC plants are switched off and building is cooled by the energy stored in the form ice. Thus, air-conditioning is provided during the day-time without actually running the large AC plants. Smart Infrastructure is another important aspect of the Smart Cities project. Intelligent power networks with the implementation of specialized IT solutions are going to be essential. The Radio frequency (RF) metering is the step towards providing error free bills and eliminating the entry process of a utility person in premises for meter reading. Radio frequency waves are a form of electromagnetic energy that are used for a variety of purposes, like telecommunications. In a word, these are Smart meters that use low-energy radio frequency waves to transmit information across distances. Radio Frequency Meters will enable a step further on providing error free bills and eliminating the entry process of a utility person in premises for meter reading. The data received will used for automated generation of bills ruling out any human intervention. The players are expected to not only increasingly contribute to the infrastructural advancement but also innovate new technology so as to enrich customer content- SMART CITIES 74 energética INDIA · MAY | JUN16
