- India presently has over 14 GW of solar rooftop PV (SRTPV) systems connected to the DISCOM grids (33kV, 22kV, 11kV and LT lines) which the System Operators (SLDCs, RLDCs and NLDC) have no visibility. Hence, the daily generation (>50 GWh) from these distributed PV plants are not being considered in the generation forecasting, scheduling and dispatching activities. The PM Surya Ghar Yojana with the target of 10 million SRTPV will add another 30 GW of SRTPV in next 3 years which will create serious issues for the DISCOMs to manage the MV/LV grids
- To monitor the generation and performance of the grid connected SRTPV systems, it is very important to have a DISCOM-wise, Feeder-wise and DT-wise registry of SRTPV installations. The DISCOM-wise registry can be scaled up to State-wise and a to a National registry of all the SRTPV units connected to the grid so that the potential generation from these resources can be taken into consideration while scheduling and dispatching by the state load dispatch centers (SLDCs)
- ISGF has prepared the National SRTPV Registry which will help in effective management and integration of SRTPV systems
- This Registry Architecture is highly scalable to include millions (or billions) of all types of DERs connected to the grid

The Honorable Minister of Power launched the National Registry of Solar Rooftop PV (SRTPV) System prepared by ISGF which will help in effective management and integration of SRTPV systems. India has over 12 GW of solar PV systems connected to the DISCOM grids (33kV, 22kV, 11kV, and LT lines) which the System Operators (SLDCs, RLDCs, and NLDC) have no visibility. Hence, the daily generation (>50 GWh) from these distributed PV plants is not being considered in the daily generation forecasting, scheduling, and dispatching activities. “To monitor the generation and performance of the grid-connected SRTPV systems, it is very important to have a feeder-wise and DISCOM-wise registry of SRTPV installations. The DISCOM-wise registry can be scaled up to state-wise and a national registry of all the SRTPV units connected to the grid so that the potential generation from these resources can be taken into consideration while scheduling and dispatching by the state load dispatch centers (SLDCs).

Roundtable Consultation Meeting on The Design of Framework for National Registry of Solar Rooftops/DERs.

Meeting held with PGVCL MD and Senior officials for the introduction of the project and seek support.
