The document describes a proposed online electricity bill payment and complaint system. Some key points: - The system would allow customers to view and pay electricity bills online, as well as lodge complaints about power issues like supply problems. - It aims to address current problems with late/incorrect bills, long travel for payment, stressful payment process, and difficulty communicating complaints. - The proposed system would integrate online bill payment and complaint functions, allow bill uploading and viewing, enable complaint submission, and provide company contact details and news. - It would be developed using tools like PHP, MySQL, HTML and deployed on a client-server architecture using Apache server. Requirements, design diagrams, methodology and GUI prototypes are

1. Online Electricity Bill Payment
and Complaint System
CN3070: Project
Name: Balogun Habeeb Abiola
UEL ID: U1159354

2. Introduction
• Online Power Billing System is an Executive Information System (EIS) that
determines the bill of the consumed power per unit time and performs its
computation based on the sale rate of power per unit time and other parameters.
• It provides an environment to maintain the consumer details
• It functions on an Intranet network and Internet domain and ensure timely
availability of status parameters.
• Customers can lodge complaint or deal with new connections just by logging into
the system.

3. Problem Statement
• Users may receive their bills late
• Users may receive the wrong bill
• Some users have to travel long distances to pay bills
• Payment process is usually stressful
• Users usually find it hard to relay complains to the electricity company based on their
power supply
• Problems regarding power supply is not quickly noticed and rectified due to the poor
communication between the electricity company and users.
• The electricity company runs on a traditional method of storing and managing
customer details
• Manually maintained files have the possibility of getting worn out, getting misplaced
or even destroyed in unforeseen circumstances
• Erroneous results in bill calculation

4. Literature Review
• Electricity gives a wide variety of well-known electrical effects, such as
lighting, static electricity, electromagnetic induction and the flow of
electrical current in an electrical wire (IEEE, 2008).
• The power sector of Nigeria has been struggling with the provision and
maintenance of stable electricity in the country (Abubakar, 2009).
• Online bill payment is an electronic payment service that allows you to set
up a secure online account to make one time or recurring bill payments
• All bills and transactions are accessed on the bill pay website (Shelley
Elmblad).
• Users may receive their bills late, or users may receive the wrong bill
• Lack of latest storage methods and facilities
• Human error

5. Proposed System
• The selected project entails the integration of online bill payment system and online complaint
system
• Consumer electricity bills can be uploaded for viewing by the consumers
• Consumers can make complains about pressing issues concerning their power supply
• Consumers can easily pay their electricity bills without stress
• Consumers can view latest news update concerning the power supply
• Both customers and staff (system administrators) can log in to the system through a secure and
validated login portal
• The electricity company can monitor the power supply through the complaint system
• The electricity company can store and manage consumer details
• The company’s contact details can be posted for the general public to see and contact easily.
