Claims:We claim:
1. A method for indicating energy savings for a distributed site, the method comprising:
receiving, by an energy management system, energy consumption data from a pre-defined area of the distributed site for a first observation period;
defining, by the energy management system, one or more service windows for the distributed site during its operation, wherein each of the service window comprises unique energy profiles for the pre-defined area of the distributed site;
applying, by the energy management system, energy saving strategy for at least one service window, based on the energy profiles, from the one or more service windows;
receiving, by the energy management system, energy consumption data from the pre-defined area of the distributed site for a second observation period;
comparing, by the energy management system, the energy consumption data of the one or more service windows of the first observation period with corresponding energy consumption data of the one or more service windows of the second observation period to obtain a saving factor;
determining, by the energy management system, one or more adjustment factors in the energy profiles based on parameters affecting the energy profiles which were not considered during the first observation period; and
indicating, by the energy management system, energy savings for the distributed site based on the saving factor and the adjustment factors.

2. The method as claimed in claim 1, wherein the one or more service windows are defined based on non-business hours, customers hours, peak hours and business hours of the distributed site.

3. The method as claimed in claim 1, wherein the one or more service windows for the distributed site are determined based on the energy profiles which vary based on the distributed site.

4. The method as claimed in claim 1, wherein the energy saving strategy includes control measures for the distributed site based on the one or more service windows defined.

5. The method as claimed in claim 1, wherein the one or more adjustment factors include at least one of addition and deletion of one or more assets of the distributed site after the first observing period.

6. The method as claimed in claim 5, wherein the adjustment factors include change in temperature leading to variations in the energy saving in the second observation period.

7. The method as claimed in claim 1, further comprising validating the energy consumption data received from the pre-defined area of the distributed site for the first and second observation period.

8. An energy management system for indicating energy savings for a distributed site, comprising:
a processor; and
a memory communicatively coupled to the processor, wherein the memory stores processor instructions, which, on execution, causes the processor to:
receive energy consumption data from a pre-defined area of the distributed site for a first observation period;
define one or more service windows for the distributed site during its operation, wherein each of the service window comprises unique energy profiles for the pre-defined area of the distributed site;
apply energy saving strategy for at least one service window, based on the energy profiles, from the one or more service windows;
receive energy consumption data from the pre-defined area of the distributed site for a second observation period;
compare the energy consumption data of the one or more service windows of the first observation period with corresponding energy consumption data of the one or more service windows of the second observation period to obtain a saving factor;
determine one or more adjustment factors in the energy profiles based on parameters affecting the energy profiles which were not considered during the first observation period; and
indicate energy savings for the distributed site based on the saving factor and the one or more adjustment factors.

9. The energy management system as claimed in claim 8, wherein the one or more service windows are defined based on non-business hours, customers hours, peak hours and business hours of the distributed site.

10. The energy management system as claimed in claim 8, wherein the one or more service windows for the distributed site are determined based on the energy profiles which vary based on the distributed site.

11. The energy management system as claimed in claim 8, wherein the energy saving strategy includes control measures for the distributed site based on the one or more service windows defined.

12. The energy management system as claimed in claim 8, wherein the one or more adjustment factors includes at least one of addition and deletion of one or more assets of the distributed site after the first observing period.

13. The method as claimed in claim 12, wherein the adjustment factors include change in temperature leading to variations in the energy saving in the second observation period.

14. The energy management system as claimed in claim 8, wherein the processor validates the energy consumption data received from the pre-defined area of the distributed site at the first and second observation period.
