Energy utilized or consumed at a given location or facility causes pulses to be generated as a function of the instant rate of energy use, and such pulses are counted at succeeding discrete time intervals. The succeeding interval summation count values are recorded in digital form at respective discrete locations on an ultraviolet UV light-erasable PROM (EPROM) contained in a removable cartridge having a UV substantially opaque case. The interval summation count values are summed to provide a grand total energy or power utilization or consumption figure which is fed into and stored at a discrete location in the EPROM memory at the end of the recording period. The succeeding interval counts are successively compared and the peak count value for that interval having the greatest energy usage within a particular total time period composed of a multiple of such succeeding discrete time intervals is recorded on the EPROM at the conclusion of the particular total time period and the cartridge is removed, after having also recorded on the EPROM in digital data form and at respective discrete memory locations the respective times of beginning and end of the particular total time period of energy use measurement and recording, as well as recording thereon the place or location of the energy use facility whose energy use is being measured and recorded.
