  4. 4. Power Generation <ul><li>India has fifth largest power generation capacity in the world. </li></ul><ul><li>Installed capacity of 162 GW (about 4% of global power generation). </li></ul><ul><li>Per capita consumption 704 kWh (world average at 2300 kWh) </li></ul><ul><li>11 th plan target of 1000 kWh per capita consumption requires additional 100 GW power generation by 2012. </li></ul>
  5. 5. Power Transmission <ul><li>The current installed transmission facility is only 13% of total installed capacity. </li></ul><ul><li>Ministry of power plans to establish integrated National Power Grid by 2012 with 200,000 MW power generation and 37,700 MW (additional 20,750 MW planned during 11 th plan) inter-regional power transfer capacity. </li></ul>
  6. 6. Power Distribution <ul><li>Transmission & Distribution losses stand at 33% substantially higher than global benchmarks. </li></ul><ul><li>Reforms have been undertaken through unbundling State Electricity Boards into separate power generation, transmission & distribution units. </li></ul><ul><li>Privatization of power distribution initiated through outright privatization or franchisee route. </li></ul>
  7. 7. Power Distribution continued <ul><li>While there has been slow and gradual improvement in metering, billing & collection efficiency, the current losses still pose a significant challenge for power distribution companies. </li></ul>
  8. 8. Generation History <ul><li>Full scale asset management & mapping </li></ul><ul><li>Predictive, preventive and routine maintenance management </li></ul><ul><li>Work order generation, activity scheduling. </li></ul><ul><li>Open system platform and database management </li></ul><ul><li>Enterprise-wise documentation management </li></ul><ul><li>Manual logging of Data </li></ul><ul><li>Huge Man power deployment. </li></ul><ul><li>Vast count of instruments and data. </li></ul><ul><li>Persons expertise required to run the machines. </li></ul>
  9. 9. Generation History Cont…. <ul><li>Manual follow up for running equipment in sequence. </li></ul><ul><li>No automatic alarm generation in case of fault. </li></ul><ul><li>No analysis provision available in the case of fault. </li></ul><ul><li>Auto staring of stand by equipment in case of failure of one is not possible. </li></ul><ul><li>Remote monitoring and control not available. </li></ul>
