ENERGY AUDIT OF CERTAIN INSTALLATIONS AT AF STN JODHPUR

M & L to carry out the energy audit by / through an Accredited Energy Auditor (AEA) certified by the BEE of entire electric supply distribution system comprising of Power/distribution transformers, Water Supply Installations, DG sets, AC plants, Motors and other E/M equipments installed at AF Stn Jodhpur. Submit complete Detailed Energy Audit Reports (03 sets) alongwith observations and recommentations to enhance energy efficient power infrastructure (addn/ altn of work required for enhancement of energy efficient power system) complete all as specified and directed.

(a) Transformers installed at AF Stn Jodhpur - 85 Nos.

(b) DG Sets installed at AF Stn Jodhpur -102 Nos.

(c) AC Plants installed at AF Stn Jodhpur -43 Nos.

(d) Solar Power Plant of 1.0 MW capacity On-grid connected-01 No

(e) Water supply installations - 27 Nos

Preliminary Activities :- (i) Site Reconnaissance Survey : Identify energy consuming areas, building types and equipment categories.

(ii) Data Collection : Past 12 months of energy bills, layout drawings, equipment inventories etc.

(iii) Stackholder Consultation : Discuss mission of critical area, Security protocols and constrains with station authorities.

(iv) Energy Consumption Profiling : Energy Mapping of all types of loads of Administrative bldgs, residential bldgs, Messes, Hospitals, Hangars, ATC towers, Street lights, Perimeter lights etc.

BRIEF SCOPE OF WORK (i) Electricity Bill analysis, Measurement and analysis of peak demand, power factor to suggest measures to reduce the maximum demand.

(ii) Detailed examination of the existing energy use pattern. Transformer loading & losses.

(iii) Performance evaluation of installed capacitors, banks/ APFC panels to ensure deliverance of desired output, level of losses, management of system power factor and operation of capacitors.

(iv) Performance evaluation of major Motors, 7.5 H. P and above, to identify under/overloading of motors power factor and suggest measures to improve performance & efficiency of the complete system.

(v) Analysis of loading pattern and losses in Transformers.

(vi) Measurement of Electrical parameters like Voltage, Current, kW, Power Factor, Voltage harmonic distortion (V THD %), current harmonic distortion (ITHD %) and Individual harmonics levels (up to 30th) at transformers.

(vii) Recommendation to improve the power quality, power factor improvement, reduction in harmonic levels, if any, to comply with IEEE 519, 2014 standards.

(viii) Evaluation of operating efficiency of DG sets by measuring specific energy generation ratio (SEGR).

(ix) Study of DG sets for load optimization to improve SEGR.

(x) Trail test of each DG sets and checking of loading pattern of DG Sets and actual load requirement..

(xi) Checking of per unit power generation w r t fuel consumption, ventilation arrangement for the DG unit room and Specific electricity generation ratio evaluation.

(xii) Performance evaluation i.e., Energy balance Efficiency calculations of DG sets. Checking of Maintenance Aspects of DG sets to improve efficiency.

(xiii) Carryout the extensive analysis of the central AC plants/VRF/Package/Ductable/Provision ACs and suggest the performance and efficiency improvements alongwith the bottlenecks in the existing system, if any.

(xiv) Carryout the detailed study of Solar Power plant 1 MW and Solar Water heaters installed in the Stn and suggest improvements to enhance the efficiency of complete system and to minimise power factor losses and Harmonic distortions.

(xv) Define the methods for energy monitoring. Need to educate Engineering team. Note : Energy Audit Reports and all recommendations should be submitted in detailed.
