The shortage in electrical power generation in Iraq due to several wars, forced the people to use an alternative solution. One of such solutions is the local power generators that distributed rapidly in Iraqi cities. The investors whom owning these generators make the prices for delivering the power to the consumers without power meters. In this paper, a smart power meter for such generators can be used in each customer place. The smart power meter simply is composed of an Arduino Pro Mini microcontroller with an ACS712 current sensor and DS3231 Real Time Clock. The sensed data is proceed using simple algorithm to calculate the required bill according to the consumed average amperes multiplied by the ampere price setting by the provider during the delivery period. The proposed meter with its low cost and fair bill calculations can be used at each end-user location for local generators.

<span>This paper proposes a cheap solution to be a starting point for building smart electrical power billing systems. Electrical power has many challenges issues in Iraq, one of these challenges and the most important is the Billing system. The smart power meter uses an Arduino Uno as the core for controlling the sensed data and transmits it to the electrical power unit for billing services. The system is constructed with two parts: the transmitting unit measures the current, voltage, power and power factor through the compact new sensor PZEM-004T. The data sensed and processed by the microcontroller which displayed the KWh on (2*16 LCD) display. This data also transmitted to the electrical power company unit via the global system for mobile communications (GSM) module (SIM900A) which is a dual band GSM/GPRS-</span><span>general packet radio service</span><span> modem. The receiving part is mainly dedicated for collecting the required consumed power data via the same (SIM900A) module and also can display it using (2*16 LCD) display. For the sake of saving these data, the receiver part uses SD ram for such purposes. With such proposed system the electrical power company can control and collect their fees monthly without loss and with minimum cost.</span>
