25 Barriers in Smart Grid Implementation in India Major hurdles are: No proven commercial viability for large scale smart grid roll out Poor financial health of most state owned T&D companies Low awareness of technological developments in the utility sector No coordinated national road map for smart grid deployment A fragmented industry 1/28/

26 Regulators role on Smart Grid The success of smart grid deployment depends quite a lot on the regulatory landscape of the utility / country. The best and most efficient smart grid products will not reap the benefits without the regulatory framework needed to make these attractive to the customer. For this purpose, a smart rate tariff should be there. 1/28/

27 Regulators role on Smart Grid Contd... In the Indian Context, any Capex intensive scheme is scrutinized by the Regulator on following criteria: Impact on Reliability Impact on AT&C Loss reduction Tariff Neutrality to the extent possible While in developed countries, Smart Grid is more driven by Reliability and Safety considerations ( including grid synchronization for renewable sources), the driver in India would continue to be tariff neutral for some time. Development of a Robust Business Case is extremely important for the effort to be recognized and approved by the regulators as currently India is in a nascent stage for implementation of Smart Grids and there is a lack of proven technology and vendors. 1/28/
