4 4 Technical Committee: Responsibilities –Identify technical parameters –Study & validate test procedures for adoption –Define criteria for Laboratories (NABL) –Identify & recommend Laboratories for testing ? –Decide on label rating plan ? –Decide parameters on label ? –Design label –Decide on enforcement mechanism and work out protocol –Carry out economic analysis for MEPS –Recommend MEPS

5 5 Recommendation Reduce temperature rise limits Due to frequent overloading in service, life deteriorates. Contributes to poor reliability. The current temperature rise limits 50/55 0 C over the ambient of 50 0 C of top oil and winding respectively. Temperature rise limits revised to 35/40 0 C over the ambient of 50 0 C of top oil and winding respectively. Implication on cost average of 3%. Similar changes helped GEB to reduce failure rate from 27% to 20%.

6 6 Basis for Star rating plan CaseBasis of losses (Total at 50% Load Condition) Base case Star 1Current purchasing practice (IS 1180 Max Losses) Star 2Some utility purchase specs like AP, NDPL Star 3Losses from TOC design (Moderate) Star 4Losses from lowest TOC design Star 5High efficiency design

7 7 X axis is PU Load & Y axis price in Rs.

8 8 Limits at 100% load

9 9 Recommendation Star rating plan –The star rating represents the loss level and will represent the efficiency status. –Star 1 is current IS level and Star 5 will be lowest loss specifications. –Star rating will represent total losses at 50% & 100% loads and at 75 0 C.

10 10 Recommendation kVAStar Rating Max Losses at 50% (Watts) Max Losses at 100% (watts)

11 11 Recommendation – 3 kVAStar Rating Max Losses at 50% (Watts) Max Losses at 100% (watts)

12 12 Recommendation – 3 kVAStar Rating Max Losses at 50% (Watts) Max Losses at 100% (watts)

13 13 Existing & Proposed efficiency levels

14 14 Comparison with international standards

15 15 Impact of star 3 on cost & material kVAStar 1Star 3 Design Material Ex-works price (Rs) Design Material Ex-works price (Rs) 25M6Al18,382M3Al/M4Cu20,941 63M5Al32,904M3Al/M4Cu41, M6Al47,149M3Al/M4Cu60, M4Al68,100M3Al/M4Cu85, M4Al82,182M3Al/M4Cu102,164

16 16 PAY BACK PERIOD STAR - 3 LEVEL

17 17 Energy saving potential in 1 st year

18 18 Recommendation Energy efficiency labels –Manufacturers would conduct the test as per the approved procedure register with BEE & display label on the transformer. –Label will display rated capacity, star rating and maximum total losses at 50% and 100% loads. –No positive tolerance on the displayed label value.

19 19 Sample DT label

20 20 Recommendation – 5 Utility purchases –Utility to improve MEPS from star 1(IS-1180) to Min star 3.

21 21 Fluorescent Tube Lights S & L Program

22 22 Lighting industry in India Total lighting market : Rs. 18,000 M ; Growth : 12% p.a. Lamps : Rs. 10,800 M : Growth : 10% p.a. –GLS : Rs. 4,500 M (435 M units) ; Growth : 5% p.a. –Tube lights : Rs. 4,200 M (136 M units) ; Growth : 10% p.a. –HID : Rs M ( 4 M units) ; Growth : 20% p.a. –CFL : Rs. 450 M ( 1 M units) ; Growth : 15% p.a. Luminaires : Rs. 7,200 M ; Growth : 15% p.a. (Ballasts, fixtures & accessories) Unorganised sector accounts for 35% of the total lighting market (value terms) –Around 440 unorganised players –Around 20 organised players Lighting accounts for 17% of total electricity consumed in India

23 23 Work on BEE S & L programme on FTL was initiated on 08 September ELCOMA was requested to spearhead the BEE S & L Programme. T-8 ( 36W ) & T-5 ( 28 watt ) Triband offers lumen efficacy of 85 lumen per watt VISION OF S & L PROGRAMME Lighting industry should strive to improve lumen efficacy of over 70 lumens per watt in about 5 years time.

24 24 In order to create market pull, the government could buy only star rated products, i.e. the highest energy efficiency products. The standards should be futuristic since there is also a time frame required for phasing out old products and introduction of efficient products. A time frame of 2-3 years was suggested. Labeling would be the first activity to be taken up in these products. VISION OF S & L PROGRAMME ( CONTINUED)

25 25 MEETINGS In first meeting of steering committee held on 27 September 2002, it was decided to form a Technical Committee having following compositions: Mr. R.Nandakishore – convener, Philips India Limited Mr. R.S.Mandal, Osram India Private Limited Mr. S.K.Neogi, Phoenix Lamps India Limited Mr. S.Ramasubramanian, Surya Roshni Limited Mr. Ramaswamy, BEE

26 26 The task of Technical Committee is to finalise: a. Testing protocol b.Technical parameters along with weightages for labeling c. Label design d. Test laboratories e.Challenge & Check testing protocol. Tasks of Technical Committee

27 27 FTL Technical Committee Recommendations For energy labeling 3 parameters should be considered which would provide efficacy from both efficiency as well as life: Lumens at 100 hrs.(initial lumens) Lumen/watt Lumen 2000 hours Lumen/watt Lumen 70 % life (3500) hours Lumen/watt. Test Procedure: relevant BIS test procedures including amendments meet all the minimum requirements of BIS to qualify for labelling BIS certification or a quality control certification, a prequalification for labelling

28 28 For 18W we have considered 940 lumens in place of 1015 lumens in BIS since this has been agreed in the last meeting of the BIS. Based on the visit of the technical team to the four Laboratories, the recommendations of the technical committee is to go for testing at NPL & ERDA after ascertaining Proficiency testing in both the Laboratories. Accreditation of NPL with NABL is under process. The 3200 lumen output lamps (Triband) was also included for testing and BIS has also agreed to go in for the standards in the last meeting FTL Technical Committee Recommendations ( Continued)

29 29 10 lamps were tested at manufacturers laboratory as well as ERDA to get comparative readings/calibration before full scale testing begins (Proficiency Testing). There were certain differences in the optical measurements in the three laboratories but these are with in the z score of proficiency testing. Since the measurements are against a standard reference lamp, it was felt necessary to ensure the quality of reference lamp. BEE to take up with NPL The lighting industry had agreed to align with ERDA laboratory FTL Technical Committee Recommendations ( Continued)

30 30 Revised Star rating Plan ( This would need another meeting with stakeholders) Star levels 100 hrs efficacy Lumens/W 2000 hrs efficacy Lumens/W 3500 hrs efficacy Lumens/W 1>47 & < 54>40 & =<46>38 & =<43 2>54 & = <60>46 & = <51>43 & = <48 3>60 & = <69>51 & = <59>48 & = <55 4>69 & = < 85>59 & = < 72>55 & = < 68 5> 85> 72> 68

31 31 Basis Values for the 100 hours efficacy was worked out taking into consideration that all Wattages and their energy efficacy is reflected the star rating plan. The values of IS with permissible tolerances for different wattages were used to arrive at the boundaries. Efforts were made to differentiate 20 W & 18 W, 40 W & 36 W and halo phosphates and Tri phosphates Star rating plan would ensure efficiency purchases. The cut off % for these categories have been fixed in such a way the categories of lamps operating with good quality control as well as above the minimum threshold would fall in the appropriate levels.
