Several commercial and residential customers of Reliance Infrastructure (R-Infra) in Mumbai are planning to shift their electricity connections to Tata Power Company (TPC).

Around 4,000 restaurants in Mumbai and its suburbs say the shift to TPC would work out to be over 50 per cent cheaper for them. The restaurants which have sought a change of supply include fine dining and mid-size restaurants and fall under R-Infra and TPC's licence areas.

"We have written to both the companies and the regulatory board Maharashtra Electricity Regulatory Commission (MERC) for a shift from R-Infra to Tata Power. It would be around 50 per cent cheaper for us," says Chandrahas Shetty, president of a restaurants' association in Mumbai.

R-Infra's licence area spreads from Sion to Kanjurmarg in Central suburbs and from Mahim to Mira-Bhayander in the western suburbs of Mumbai. TPC's licence area overlaps with that of R-Infra.

R-Infra's consumer base is largely residential, forming around 85 per cent of its customer base, with commercial users comprising 14 per cent.

"TPC states that it will be able to supply power to those existing consumers of R-Infra who wish to receive power from TPC. For effecting supply, TPC would use the existing distribution system of R-Infra," MERC stated in a recent interim order given on a petition filed by TPC. The company had sought approval for operating procedures for supplying power to consumers in the common licence area of R-Infra using each other's existing distribution network.
