his case study presents the smart grid pilot projet that is being implemented in the city of Puducherry in India, since 2016.
A medium-scale town of 1,2 million inhabitants, the city of Puducherry is suffering from rapid urban population growth (almost 3% per year between 2001 and 2011). Puducherry faces increasing difficulties to provide electricity to its population and ensure reliability of the network. Although the electrification process of Puducherry is well above India’s national average (78,7% of India’s population have access to electricity), 31% of the electricity is lost in transmission and distribution lines. The electricity provision system is inefficient due to ageing and overloaded infrastructures. This results in unreliable delivery and regular power shortfalls in many areas; frequent metering errors due to manual reading of old metering systems and inefficiencies in energy accounting and billing, resulting in revenue losses.
In 2013, the Electricity Department of Puducherry, in partnership with the Power Grid Corporation of India Ltd (PGCIL) and a consortium of 50 energy and IT companies, implemented a SMART grid pilot project to showcase the feasibility of digital grids, to later on scale-it up city-wide. It aimed at implementing all features of digital grids, including:
Although the Puducherry pilot project was implemented at a small scale, and results will be visible once the project is scaled-up, the city power utility expects several benefits, including: increased management efficiency (possibility to remotely proceed with power connections and disconnections); enhanced reliability of the electricity network (less interruptions and quicker restoration) and consumers are better informed about their consumption. In addition, the Puducherry Electricity Department envisages an important reduction in distribution losses from 31% percent to 10%, as well as increased revenue and reduced expenses with a tariff collection efficiency improvement from 90 percent to 98 percent. The resultant benefit is estimated at $ 2.5 million USD annually.
