6 Apart from the above projects following suggestions are made for further savings. Switching off computers, lighting and electrical loads when not in use. Reduction in ventilation load by closing the air grills wherever not necessary like in near windows and scrap dump area. Reduction of current unbalanced load at the Main DB by correcting the balancing of circuits Installing Roof Top Solar PV power plant The office is having good shadow free roof top space near Cafeteria, installed Solar PV power plant and generate electricity which is catering the lighting load 7/30/2018 6

7 CLEINT 2 This client is a part of the global Group. They are into manufacturing of tungsten wires, sheet metal products of tungsten, molybdenum and tantalum and machined products of these materials. The products are widely used in lighting, semiconductor applications and wire EDM. The total electricity bill for the company is Rs lakh per annum. Additionally, LPG cost is around 60 lakh and diesel for DG set is around 5 lakh per annum 7/30/2018 7

8 S. No. Present Status Recommendation Yearly Savings Approxi mate Investm ent Simple payback period kwh/year Rs./year Rs. Year A Projects with low investment 1 Main air compressor of 90 kw and a 11 kw air compressor for H2N2 plant are operated separately. Use of compressed air from main air compressor for H2N2 plant, instead of running a separate air compressor for 65,505 4,32,066 75, H2N2 plant 2 Existing 2x 1000 lpd Solar water heater panels are oriented more towards east than south reducing their output Reorient the panels properly to due south and get the designed output. This will reduce the electricity consumption for hot water generation 14,244 93,953 7/30/2018 8

9 B 3 Medium term projects with little investment The existing cooling tower pump of 9.3kW is oversized Install a VFD to avoid throttling and outlet is throttled close to losses 50%. 18,144 1,19,676 60, Cooling Tower fan is continuously operated without any temperature feedback Installed temperature controller to switch on switch off the cooling tower fan based on 7,740 51,052 25, temperature setting 5 18W CFLs are used for outdoor lighting.(24 No.) These CFLs can be replaced by 9W LED bulbs ,155 3, x 36W FTLs are used at some of the places (12 No.) Replace these FTLs by 2 x18 W LED tube lights 1,964 12,955 24, /30/2018 9

10 S. No. Present Status Recommendation Yearly Savings Approx Investme nt Simple payback period kwh/year Rs./year Rs. Year C Long term and with considerable investment The existing 90kW air compressor is poorly loaded 7 at 38%. Even after considering the usage of H2N2 plant its loading will improve to 52%, wasting lot of energy in unload condition Install a properly sized air compressor of 55kW to optimize the loading percentage 1,57,341 10,37,802 14,00, The production area lighting is 8 done by 2 x 28W FTLs (799 No.) Replace these fixtures by 2 x 18W LED tube lights. 92,732 6,11,650 14,02, /30/

11 Simple Approx. S. No. Present Status Recommendation Yearly Savings payback Investment period kwh/year Rs. /year Rs. Year 9 Electric heaters are used in hot water generation for heating the water required for chemical cleaning. Solar water heating system with heat exchanger can be provided to reduce the 72,000 4,74,903 20,00, power consumption. 10 Good roof top area is vacant for harnessing Solar energy. (Admin block 715 m 2 and Production Area 3666 m 2 ) Roof top Solar PV power plant to the tune of 400 kwp is possible combining the Admin and 5,78,160 38,13,473 3,20,00, Production blocks. Total 10,08,764 66,53,685 3,69,89, /30/

12 Apart from the above projects following suggestions are made for further savings. Reduction of compressor load pressure from 6.5 bar to 6.0 bar in 90 kw compressor. The unload power of the 90kW is around 58kW, which is on higher side and hence needs to be checked from maintenance and setting point of view. Providing solar hot water to hot water generation section for top up and refilling purposes. Presently this is used only in boiling section. Idle running of machines to be avoided by proper planning. This is leading to huge losses over a year as the heaters of the machines will be On even if the production is not there to maintain the set temperatures. Insulation needs to be improves in machines especially in AS and 17F machines where heat losses are considerably high. 7/30/

13 Reduction in ventilation load by closing the air grills wherever not necessary like in scrap dump area. Reduction of current unbalance at the Main transformer DB by correcting the balancing down streams. The ammonia heater usage to be optimized by switching on the heater for the cylinder which is in service and switching off for the other two on standby. 7/30/
