Sector lines also • Figures do not include 600MW (in aggregate) pertaining to various 132kV

  8. Renewable Integration

  9. Renewable Addition Plan RE Penetration

  10. Renewable Integration - Challenges • Issues • Short Gestation period (9-12 months) • Variability & Intermittency • Low Utilisation Factor

  11. Initiatives

  12. Green Energy Corridors

  13. Green Energy Corridor-I Green Energy Corridors-Inter State Transmission • Green energy corridor to facilitate Grid integration of large scale renewables • About 33GW capacity addition envisaged through wind & solar in next 4-5 years • The Plan includes • Transmission Strengthening(s) –Intra & Inter • Dynamic reactive compensation • Energy Storage • Smart grid applications • Establishment of Renewable Energy Management Centre enabling forecasting of renewable generation, real time monitoring, etc. ​
