M ETHODS TO MEASURE AND IMPROVE D ISTRIBUTION SYSTEM RELIABILITY Performance indices System average interruption frequency index (SAIFI) SAIFI = (total no. of customer interruption / total no. customer served) System average interruption duration index (SAIDI) SAIDI = (sum of the customer interruption duration / total no. customer)

5. M ETHODS TO MEASURE AND IMPROVE D ISTRIBUTION SYSTEM RELIABILITY Customer average interruption frequency index (CAIFI) CAIFI = (total no. of customer interruption / total no. customer affected) Customer average interruption duration index (CAIDI) CAIDI = (total no. of customer interruption duration / total no. of customer interruption) Average service availability index (ASAI) ASAI = (8760 – SAIDI) / 8760

6. Effective Distribution Management using Smart Grids

7. P RESENTATION STRUCTURE Distribution Infrastructure in India Overview of smart grid Key technologies and solutions Smart Grid in India

8. D ISTRIBUTION I NFRASTRUCTURE IN I NDIA  80% of villages are ‘electrified’, yet… 45% of the population doesn’t have access to electricity  ~400 Million people without electricity (US population ~300 Million)  Aggregate Technical and Commercial (AT&C) losses are very high >25% on average, >50% in many states  High electricity ‘theft’; poor policing / enforcement due to political reasons  Subsidies to agricultural sector  Free or very low-cost power which is often un-metered  Hard to separate free power from ‘theft’

9. D ISTRIBUTION INFRASTRUCTURE IN I NDIA ( CONT..)  ~60 Electricity Distribution companies in India Generally state-owned monopolies Generally loss making entities (average loss 11% of sales / year mainly due to high AT&C losses and poor revenue collection)  Reform of the distribution sector identified as a key need by the government - APDRP, R-APDRP – Reducing AT&C losses a key focus Open-Access for the distribution network to foster competition Laws against theft - better enforcement, better communication Privatization & Franchising of distribution network Demand Side Management – especially in agricultural sector Rationalization of tariffs and removal of cross-subsidies
