Bharuch is served by Dakshin Gujarat Vij Company Limited (DGVCL), the south Gujarat distribution licensee, headquartered in Surat and running a Bharuch circle office at Maktampur. DGVCL covers seven districts: Bharuch, Narmada, Surat, Tapi, Dang, Navsari and Valsad. Gujarat has three other state discoms, and none of them serves you here. MGVCL covers the Vadodara side, PGVCL covers Saurashtra and Kutch, UGVCL covers north Gujarat. Torrent Power is a private licensee in Ahmedabad, Gandhinagar and part of Surat city, and it has no licence area in Bharuch. Pages that file Bharuch under MGVCL because Vadodara is an hour up NH-48 are pointing you at the wrong utility and the wrong portal.
The commercial terms come from the Gujarat Electricity Regulatory Commission (GERC), not from the discom and not from us. Under the GERC framework, a rooftop system is capped against your sanctioned load, and every consumer category may apply. Surplus units you export earn credit against what you draw at night and through the monsoon. Load enhancement is a separate application, and it is worth doing before sizing if your connection is old and small.
One practical note for Bharuch. Your DGVCL consumer number, the name on the bill and the name on the property papers all have to agree before feasibility clears. Inherited connections and shop-cum-residence meters are the two cases that trip up here, and both are fixable, but fixing them after the panels arrive wastes a month. We check this at the survey.
