Govt. of India has set a target for establishing 175 GW renewable capacity by 2022 which includes 100 GW Solar, 60 GW Wind generation capacity. MNRE vide its order dated 08.06.2018 had constituted a Sub-Committee to identify ISTS connectivity for renewable energy projects from potential solar energy zones (SEZs) and potential wind energy zones (WEZs) of about 50 GW and 16.5 GW respectively. Accordingly, SEZs and WEZs envisaged in 7 RE rich states (Tamil Nadu, Andhra Pradesh, Karnataka, Gujarat, Rajasthan, Maharashtra and Madhya Pradesh) were identified by SECI in association with MNRE in consultation with RE power developers.
A total of 28 GW RE capacity has been identified in Western Region out of which 2 GW Wind generation capacity has been identified in Osmanabad area in Maharashtra. Out of this, 1 GW has been proposed to be integrated with Intra-state system and the balance 1 GW with ISTS. Transmission System for Renewable Energy Zones (REZs) in Western Region [including Osmanabad Wind energy zone(WEZ)] was finalised in the 2nd WRSCT meeting held on 21.05.2019.
The subject scheme will enable integration of 1 GW WEZ in Osmanabad area with the ISTS grid. The details of transmission planned specifically for Osmanabad WEZ is depicted below:
a) Establishment of 2x500MVA, 400/220kV near Kallam PS
b) 1x125MVAr bus reactor at Kallam PS
c) LILO of both circuits of Parli(PG) – Pune(GIS) 400kV D/c line at Kallam PS
d) Provision of new 50MVAr switchable line reactor at Kallam PS end of Kallam – Pune(GIS) 400kV D/c line
e) Conversion of 50MVAr fixed Line Reactors on each ckt pf Parli (PG) - Pune (GIS) 400kV D/c line at Parli (PG) end into switchable line reactors
