<h1>Competitive bidding compliance: tariff adoption rejected for lack of required central approval; re bidding ordered under Section 63.</h1> Tariff adoption was rejected due to failure to comply with competitive bidding requirements under Section 63: the petitioner obtained state rather than central approval for deviations despite the ISTS nature of the project, awarded capacity to a related subsidiary raising transparency concerns, and misapplied short term market comparisons; the Commission directed re bidding strictly under the Section 63 guidelines.
