Abstract: A reliable electricity grid without interruptions is imperative for a growing economy like
India’s. In an interconnected electricity grid, complete with complexities, the impetus of
maintaining the stability of the grid through sustained, optimal usage rests with the end-user
and also with the power supplying utility. The electricity demand side management (DSM) is
one such approach for sustained development which when deployed leads to lesser capacity
addition in the grid, better utilization of power by the end-user thus leading to stability of the
grid and reliable power. The reduction in demand not only benefits the customer but also the
supplying utility by de-congesting the distribution network. Thermal storage used in HVAC
applications in commercial establishments is one such technological option for
implementation of DSM programs. The DSM initiatives require monetary incentives for the
customer to implement them. The attempt of comparing the saved energy (negawatts) with
the electricity prices in the energy exchanges on a real time basis was carried out. The
economics of electricity supply by the utility and the electricity demand of a notional
commercial building were compared and optimum cost of power saved for the negawatts was
found out and compared with the exchange traded market price of electricity. The resultant
analysis shows that the negawatts can indeed be traded in the open market and has great
market potential both from a technological perspective and as well as a commercial one.
