2. The facts relevant for deciding these appeals very briefly are that on 29.04.2000 the appellant entered into a Memorandum of Understanding with Non-Conventional Energy Development Corporation of Andhra Pradesh Limited (for short D . 'the NEDCAP'), a nodal agency for non-conventional projects up to 20 MW, for setting up of a power plant in which power was to be generated from bagasse, a by-product of sugar factory. On 25.01.2002, the Andhra Pradesh Electricity Regulatory Commission (for short 'the APERC') set up under E the Andhra Pradesh Electricity Reforms Act, 1998, permitted the appellant-company to supply the power generated in its plant to the respondent no.1, which had taken over the functions of the erstwhile Andhra Pradesh El~ctricity Board.

On 01.03.2003, the appellant wrote to the APERC to direct the respondent no.1 to purchase unutilized power of the. appellant as sugar .plant of the appellant could not be H commissioned due to some difficulties and power generated SAGAR SUGARS & ALLIED PRODUCTS LTD. v.

On 17.03.2003, the Chief Engineer of respondent No.1 wrote to Superintending Engineer directing him to stop evacuation of power from the power plant of the appellant and B to cut off the supply on the ground that the plant of the appellant cannot be classified as co-generation till the sugar plant of the appellant was commissioned.

3. The appellant then filed Writ Petition No. 7395 of 2003 C in the Andhra Pradesh High Court challenging the letter dated 17.032003 of the Chief Engineer of the respondent ~o.1 and the learned Single Judge passed the orders on 02.05.2003 directing issue of notice to the respondents and directing the respondents, as an interim measure, to purchase power from the appellant and to pay to the appellant Rs.2.00 per 11nit. The D respondent No.1 then filed a review petition before the APERC for reconsideration of its earlier directions to amend the PPA issued on 17 .03.2003 and on 01.10.2003 the APERC allowed the- review petition and cancelled its directions issued on 17.03.2003. The appellant then challenged the order dated E 01.10.2003 of the APE RC before the Division Bench of the High Court in C.M.A. No. 3613 of 2003 and the Division Bench of the High Court granted interim stay of the order dated 01.10.2003 of the APERC.

B 5. Finally on 30.07.2004, the Division Bench of the High Court passed the impugned order in Writ Appeal No. 191 of 2004 as well as in C.M.A. No. 3613 of 2003 setting aside the order dated 15.12.2003 of the learned Single Judge in Writ Appeal No. 7395 of 2003 and directed the parties to approach C the appropriate forum chosen by the parties under the PPA for resolving the dispute. By the impugned order the Division Bench also held that the appellant will be entitled to tariff as fixed by the Division Bench of the High Court in Writ Appeal No. 371 of 2004. D

6. Dr. Rajeev Dhavan, learned senior counsel for the appellant, submitted that the sugar plant has, in the meanwhile, commenced the production on 21.01.2004 and the only dispute which has to be decided by this Court is VJith regard to the price E of the power supplied by the appellant to the respondent during the period from 13.01.2003 to 21.01.2004. 7. Mr. Dhavan submitted that by the order dated 22.04.2004 of the Division Bench in Writ Appeal No. 371 of F 2004, the respondent No.1 was to be paid at the revised rate of Rs.2.69 per unit and on 08.02.2006, this Court has by an interim order, directed that the appellant would be entitled to receive payment at the rate of Rs.3.11 per unit as an interim measure for the period from 13.01.2003 to 20.01.2004 and also at the same rate of Rs.3.11 per unit for the period G 21.01.2004 onwards, as has been paid to other co-generating plants, excluding the money already paid. He submitted that in Transmission Corporation of Andhra Pradesh Limited and Another etc. etc. v. Sai Renewable Power Private Limited and Others etc.etc. [(2010) 6 SCALE 541= (2010) 8 SCR 636 = H JT 2010 (7) SC 1] this Court has issued some directions SAGAR SUGARS & ALLIED PRODUCTS LTD. v. 1011 TRANSMISSION CORPN., OF A.P. LTD. [A.K. PATNAIK, J.]

relating to price payable for power supplied by non-conventional A power projects. He referred to Para 4 of the judgment of this Court in the aforesaid case to show that the APERC had approved the rate of Rs.2.25 per unit with 5% escalation per annum from 1994-1995, being the base year, for supply of power generated by the non-conventional power projects and B this was also the price fixed in clause 2.2 of the P.P.A for supply of electricity by the appellant to the respondent no.1. He submitted that the benefit of the aforesaid judgment of this Court delivered on 08.07.2010 should therefore be granted to the appellant and directions be issued to respondent no.1 c accordingly.

8. Learned counsel for respondent no.1, on the other hand, submitted that the judgment of this Court delivered on 08.07.2010 in Iransmission Corporation of Andhra Pradesh Limited and Another etc. etc. v. Sai Renewable Power Private D Limited and Others etc.etc. (supra) was on tariff and purchase price of power produced by co-generation non-conventional energy plants and the plant of the appellant was not a co-generation plant during the period from January, 2003 to January, 2004, as there was no production of sugar in the plant E during the aforesaid period and therefore the judgment of this Court in Transmission Corporation of Andhra Pradesh Limited and Another etc. etc. v. Sai Renewable Power Private Limited and Others etc.etc. (supra) has no relevance to the price of power supplied by the appellant to the respondent No.1 F during January, 2003 to January, 2004. 9. We have considered the submissions of the learned counsel for the parties and we find that clause 2.2 of P.P.A. between the appellant and respondent no.1 reads as follows: G "2.2. The company shall be paid the tariff for the energy delivered at the interconnection point for sale to APTRANSCO at Rs.2.25 paise per unit with escalation at 5% per annum with 1994-95 as base year and to be revised on 1st April of every year up to the year 2003- H 1012 SUPREME COUR'r REPORTS (2011] 12 S.C(.R.

A 2004. Beyond the year 2003=2004, the purchase price by APTRANSCO will be decided by Andhra Pradesh Electricity Regulatory Commission. There will be further .review of purchase price on completion of ten years from the date of commissioning of the project, when the B purchase price will-be reworked on the basis of Return on Equity, O& M expenses and the Variable Cost.

The dispute between the appellant and respondent No.1 before us is whether or not during the period 13.01.2003 to 21.01.2004, when the sugar plant of the appellant had not C corrunenced production of sugar, the unutilized power supplied by the appellant to the respondent No.1 will have the same price as the price of power supplied by rron-cQnVentional energy projects in the State of Andhra Pradesh determined by the APERC. It will be more appropriate for the APERC, which is a D regulatory commission with expertise in determination of price and tariff of power, to decide what would be the price for supply . of power by )he appellant to the respondent no.1 during the disputed period 13.01.2003 to 21.01.2004 and thereafter. By the judgment dated 08.07.2010 of this Court in Tr:ansmission E - Corporation of Andhra Pradesh Limited and Another etcr.. etc. v. Sai Renewable Power Private Umited and Others etc.etc. - · (supra), this Court has also remanded the matters to APERC to decide the 'purchase price' for proeurement of the electricity generated by non-conventional energy developers in the facts r:: of the circumstances of the case.

10. We, therefore, dispose of these appeals by directing that the APERC will consider all relevant materials and factors and finally determine the price of power supplied during the G period 13.01.2003 to 21.01.2004 and thereafter and in accordance with the determination made by the APERC, balance payments, if any, will be made by the respondent no.1 to the appellant.
