Distributed generation involves small-scale power generation near customers. The document outlines the vision for a distributed system with both central and localized generation sources like solar PV and fuel cells. It discusses traditional centralized utilities and the potential benefits of distributed generation for both utilities and customers, such as improved reliability and lower bills. Safety standards for connecting distributed generation to the grid are also mentioned.

Using DG [1],[2]
 Maximum use of standby Generation
capacity through safe parallel operation
with the utility grid
 Cost-effective solution consistent with
least cost planning
 Improved system load factor-LF
 Enhanced voltage- stability and avoided
line loss/Blackout during heavy-load
 Dispatchable peak demand reduction
 Improved customer Reliability

9. Customer Benefits of DG [1]
 Electricity-Bill reduction
 Reliability improvement
 Power Quality (PQ) improvement
 Utility-Customer partnerships
 Alternative Generation
 Green Renewable Electric Energy

10. Interconnection requirements [1]
