LDC DG Connection Requirements
As more distributed generation is added to the grid, LDCs (local distribution companies) are increasingly including remote DG M&C (distributed generation monitor and control) requirements to IPPs as a condition for connection in the CIA (connection impact assessment). This is particularly true of systems above 50kW in heavily loaded urban areas. As renewables become a larger portion of total supply, LDCs need to be able to remotely monitor DG sites and issue shutdown/restart commands from their SCADA (supervisory control and data acquisition) systems.

This requires additional site equipment that can interface to utility protocols DNP3 and IEC61850 using different communication media such as fiber, WIMAX, proprietary radio and 3G cellular as specified by the LDC. Cachelan can design, program and commission this additional equipment to meet each LDC DG M&C requirements necessary for successful grid connection permission.
