A method, a system and a computer program product for determining power consumption levels for granular segments of program code in a data processing system. A power profiling utility (PPU) utilizes/comprises a power monitoring module, a power profiler module, a performance profiler and a power modeling component which enables PPU to efficiently characterize power consumption of various types of applications. The PPU uses a power measurement device to obtain power consumption measurements corresponding to execution of a first code segment. Additionally, the PPU identifies information about program characteristics of granular code segments within the first code segment. The PPU then determines total power consumption for execution of the first code segment from an aggregation of power consumption measurements corresponding to all iterations of the first code segment. Ultimately, the PPU derives from the total power consumption calculated for the first code segment a finer grained power profile by using the program characteristics information and power modeling information.
