There's hardly any hardware to understand, just a driver for the relay, an LCD text module, a card slot, and an EEPROM for non-volatile data storage - it's extremely simple hardware.

i wanted to implement a similar prepaid energy meter which also employs time of the day concept ie the tarifff is more during the peak hours.....Will a pic say 16f877 be appropriate to use?

I am working on an Energy Meter project myself, using MCP3909 from Microchip. You can have a look at its datasheet, it can be helpful. Microchip also have some reference designs for energy meters.
Try MSP 430 from Texas Instrument.
ADE7166/7169 from Analog Devices. ( Both well known chips for single phase energy meter design )
The refrence designes are available on respective websites. and should be fine for project level energy meter design.
