Lunawada is supplied by Madhya Gujarat Vij Company Limited (MGVCL), the GUVNL distribution company for central Gujarat, with its corporate office in Vadodara. MGVCL's own contact directory places Lunawada in the Godhra O&M Circle and lists two town sub-divisions, Lunawada 1 and Lunawada 2. A separate Kothamba sub-division serves the Kothamba side of the taluka, and Santrampur, Kadana, Virpur, Bakor and Balasinor each have their own. The Mahisagar district administration lists the MGVCL division office at Jesingpura on Godhra Road. Your bill names the sub-division that holds your connection.
No part of Lunawada falls in a Torrent Power licence area, and UGVCL, DGVCL and PGVCL do not serve the town. Mahisagar was carved out of Panchmahal and Kheda in 2013, but supply stayed with MGVCL throughout. Older paperwork that says Panchmahal is not a sign of a different utility.
The commercial rules come from the Gujarat Electricity Regulatory Commission (GERC), not from MGVCL or any installer. Under GERC's rooftop framework, system size is capped against your sanctioned load and every consumer category can apply. Exported units are set off against imported units on your bill rather than paid out as cash. If you want more kilowatts than your load allows, the load-extension request goes in before the solar application.
