1. Transmission system for 18.5 GW of Solar and Wind Energy Zones in Southern Region

Transmission system for 18.5 GW of Solar and Wind Energy Zones in Southern Region was discussed and agreed in the 2nd SR SCT meeting held on 10.06.19.

The details of the scheme, its justification, estimated cost and its tariff impact, results of the system studies, study assumptions & inputs considered, stakeholder consultation/approval details etc. are attached for your observations, if any latest by 25.08.19  at mail ids anilsehra@powergridindia.com; ankush.patel@powergridindia.com

 

2. TRANSMISSION SYSTEM FOR EVACUATION OF POWER FROM POTENTIAL SOLAR AND WIND ENERGY ZONES IN WESTERN REGION – PHASE II (REZ PHASE II) AND TRANSMISSION SYSTEM FOR PROVIDING IMMEDIATE CONNECTIVITY TO DHOLERA UMSP

Transmission System for Evacuation of Power from potential Solar and Wind energy zones in Western Region  (Phase II) and Transmission system for providing immediate connectivity to Dholera UMSP was discussed and agreed in the in the 2nd WRSCT meeting held on 21.05.2019. The details of the scheme, its justification, estimated cost and its tariff impact, results of the system studies, study assumptions, stakeholder consultation/approval details etc. are attached for your observations, if any latest by 20.08.19  at mail ids psdas@powergridindia.com; pratyush.singh@powergridindia.com

3. Transmission System strengthening for potential solar energy zones (11.1GW) –Phase -II in Northern Region (8.1GW under ISTS and balance 3.0GW under Intra-State by RVPN).

Transmission System  for Solar Energy Zones (SEZs) in Rajasthan under Phase-II involving Hybrid system with EHVAC and VSC based HVDC was discussed and technically agreed in the 4th NRSCT meeting held on 25/07/19. Accordingly, the details of the scheme, justification, estimated cost and its tariff impact, results of the system studies, study assumptions, stakeholder  consultation/approval details etc. were uploaded on CTU website on 14/08/2019 and forwarded to stakeholders(Generators, STUs, RLDCs, SLDC & Distribution Licensees) for their observations by 28/09/2019.Subsequently, the transmission system was again taken up in 5th NRSCT meeting held on 13/09/2019. During the meeting, various alternatives, viz. EHVAC system and Hybrid system with EHVAC and VSC based HVDC system  were discussed. It was observed that it would be difficult to implement VSC based HVDC transmission system by Dec’21 matching with anticipated RE generation projects. Further, Hybrid of HVDC and AC system is found to be about Rs. 4500 – 5000 Cr. costlier compared to AC system. Considering above aspects as well as phased implementation of generation projects, EHVAC transmission system alongwith STATCOMs for reactive power control was agreed in 5th NRSCT meeting (MOM awaited).Considering above, details of the revised scheme, justification, estimated cost and its tariff impact, results of the system studies, study assumptions, stakeholder  consultation/approval details etc. are attached for stakeholders(Generators, STUs, RLDCs, SLDC & Distribution Licensees) observations, if any, latest by 05/10/2019 at mail ids rverma@powergridindia.com; yvmsprakash@powergridindia.com.
