HVAC Challenge Program for commercial consumers of TATA Power

The program is the first of its kind to be developed by any utility in India. The objective of the program is to reduce the energy consumption in ancillary equipments of operating centralized HVAC system. The ancilliary equipments of centralized HVAC system consist of cooling water pumps, primary and secondary chilled water pumps, cooling tower, AHU's etc. As a first step for program design we conducted a walkthrough audit of 3 nos. buildings. The walkthrough audit captured the working parameters of HVAC systems and established the specific energy consumption (SEC) for operating chillers with potential energy saving areas in ancillary equipments and scope for reducing the existing SEC. The walkthrough audit study estimated the potential energy savings of 3.83 MU and energy cost savings of INS Rs. 19.1 million/year. The total investment potential to realize the saving is estimated to be INS Rs. 8.3 million. Based on these results we decided to target 10% reduction in energy consumption of centralized HVAC systems each of capacity of either 350 TR or 200 TR used by 100 consumers of TATA power. The cost benefit analysis for the same is shown in table below:

We are also looking up the opportunity for bundling up the project as CDM project under AMS II.E/AM0060 with requirements for baseline development and overall monitoring and analysis.
