In the above order, the words 'the State Commission could not restrict the operation of its order effective from 17-08-2010 as the same has to be made effective from the date when third party purchase through open access was permitted by the Electricity Board' are very significant. In line with the APTEL's Order, the Commission in its Order dated 25-02- 2013 in R.A.No.4 of 2013 directed that the date of effect of the Commission's Order dated 07-09-2010 in M.P.No.6 of 2010, M.P.No.9 of 2010 and M.P.No.17 of 2010 and D.R.P.No.9 of 2010 shall be 17-07-2009. In this Order, the Commission took into account only one date i.e. 17-07-2009 the date on which the TANGEDCO permitted open access to HT consumers with sanctioned demand of 250 kW and above. However, as rightly pointed out by the petitioner, the TANGEDCO permitted third party power purchase for the consumers with sanctioned demand of 500 kW and above with effect from 30-12-2008 and for the consumers with sanctioned demand of 250 kW and above with effect from 17-07-2009. These are two different dates on which the TNEB permitted open access for HT consumers with different sanctioned demand limits. The Commission accepts that the effective dates of Commission's Order in R.A.No.4 of 2013 should have been 17-07-2009 for the consumers with sanctioned demand of 250 kW and above, and 30-12-2008 for the consumers with sanctioned demand of 500 kW and above. Accordingly, in line with the direction of the Hon'ble Appellate Tribunal for Electricity, the Commission hereby directs that the date of effect of the order dated 07-
