1.1 Introduction
Electricity is one of the most essential components of modern socio-economic development, serving as a critical resource for household activities, industrial operations, and national growth. Energy consumption in households constitutes a significant proportion of total electricity demand in many countries, including Nigeria. As populations increase and urbanization expands, the demand for electricity continues to rise, creating the need for efficient energy management systems that promote accountability, transparency, and conservation (International Energy Agency, 2023).
A smart meter is an advanced electronic device that records electricity consumption in real time and communicates the information automatically between consumers and electricity distribution companies. Unlike traditional analog meters, smart meters provide accurate consumption data, eliminate estimated billing, facilitate remote monitoring, and enable consumers to track and manage their energy usage more effectively (Gungor et al., 2013). Smart metering technology has become a major component of smart grid systems worldwide because of its potential to improve energy efficiency, and support sustainable energy management practices.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Electricity is a fundamental requirement for economic development, industrial growth, and improved living standards in every modern society. The availability and efficient utilization of electricity significantly influence household welfare, productivity, and overall quality of life. In developing countries such as Nigeria, electricity consumption continues to increase due to rapid population growth, urbanization, technological advancement, and the growing dependence on electrical appliances for domestic activities. Consequently, the need for effective electricity management systems has become increasingly important to ensure efficient energy utilization and sustainable power sector development.
The Nigerian electricity sector has historically faced numerous challenges, including inadequate power generation, poor transmission infrastructure, energy losses, electricity theft, inaccurate billing systems, and limited access to reliable metering. These challenges have contributed to inefficiencies in electricity distribution and have negatively affected both electricity providers and consumers. A meter serves as the primary instrument for measuring electricity consumption by households and other consumers. Traditional electricity meters require manual reading and are often associated with errors arising from human intervention, delayed data collection, and inaccurate recording of electricity usage. To address these shortcomings, many countries have adopted smart metering technology as part of broader efforts to modernize electricity networks and improve energy management practices.
According to Gungor et al. (2013), smart meters are advanced electronic devices designed to automatically record electricity consumption and transmit consumption data between consumers and utility providers through communication networks. The authors reported that smart meters provide real-time information on electricity usage, improve billing accuracy, facilitate remote monitoring, and support efficient management of electricity distribution systems. The introduction of smart meters has therefore become a significant component of smart grid development across many countries.
The global adoption of smart metering has been driven by the growing need to enhance energy efficiency and reduce electricity wastage. According to the International Energy Agency (2023), smart metering technologies contribute significantly to energy conservation by providing consumers with detailed information about their electricity consumption patterns. The organization reported that access to real-time energy data enables households to make informed decisions regarding electricity usage, thereby reducing unnecessary consumption and promoting energy-saving behavior.
Darby (2018) asserted that households tend to modify their electricity consumption behavior when they are provided with accurate and timely information regarding their energy usage. The author stated that smart meters encourage greater consumer awareness, promote energy conservation, and improve household participation in energy management initiatives. This suggests that smart metering has the potential to influence electricity consumption patterns positively.
Nigerian Electricity Regulatory Commission (2023) reported that, several metering programs have been introduced to ensure that electricity consumers are provided with functional and accurate meters. The Commission reported that improved metering infrastructure is expected to enhance transparency, reduce billing disputes, improve revenue collection, and strengthen consumer confidence in the electricity distribution system. Among Nigeria's electricity distribution companies, Eko Electricity Distribution Company (EKEDC) occupies a strategic position because it serves some of the most densely populated and economically active areas in Lagos State. The company's operational coverage includes residential, commercial, and industrial consumers whose electricity demands continue to increase.
This study is set against the backdrop of increasing efforts to modernize electricity metering systems in Nigeria, improve household energy management, eliminate estimated billing, enhance consumer satisfaction, and evaluate the effectiveness of smart meter implementation on energy consumption among households served by Eko Electricity Distribution Company in Lagos State.
1.3 Statement of Problems
Investigation revealed that the availability of accurate and efficient electricity metering remains a major concern in Nigeria's power sector. For many years, households have faced challenges associated with estimated billing, inaccurate energy consumption records, billing disputes, and limited access to information regarding their actual electricity usage (NERC, 2023). In Lagos State, where electricity demand is particularly high due to rapid urbanization and population growth, Eko Electricity Distribution Company has invested in smart meter deployment to address metering challenges and improve operational efficiency.
Furthermore, the effectiveness of smart meters depends not only on their installation but also on consumers' ability to understand and utilize the information provided by the technology. Where consumers lack adequate awareness or fail to monitor their energy usage regularly, the expected benefits of smart metering may not be fully realized. Similarly, technical challenges, infrastructure limitations, and service interruptions may reduce the effectiveness of smart meter systems and limit their contribution to efficient energy management (Darby, 2018). It is against this backdrop that this study seeks to evaluate smart meter implementation on energy consumption in Nigerian households, with particular reference to Eko Electricity Distribution Company, Lagos State.
