Kochi: The Kerala State Electricity Regulatory Commission (KSERC) has failed to live up to its responsibility as an independent agency protecting the interests of the consumers in the state from unscientific and unjust practices of Kerala State Electricity Board Ltd (KSEBL). The tariff hike approved by the Commission on July 8, more than the amount sought by the KSEBL, shows the failure of the agency to act as an independent regulator, said Dijo Kappan, a consumer activist.
