IKEJA Electric, Nigeria's Largest Distribution Companies

1. Huawei AMI Solution Assists Nigeria’s IKEJA Electric in Achieving Highly Efficient Electricity Usage

2. IKEJA Electric, Nigeria's Largest Distribution Companies Leading the Industry, Facing FierceCompetition Background • IKEJA Electric is one of 11power distribution companies in Nigeria. • IKEJA Electric is responsible for power generation and distribution in three states. • There are 530,000electrical users on the live network. • The power supply and annual earnings rank of IKEJA Electric arehighest. • The competition is fierce. The difference between power supply of IKEJA Electric and IBADAN Electric is smaller than 100 GWh. • Annual power supply(GWh) Annual earnings (MUSD)

3. Challenges: Low ROI, Impact on Business Operations Low Office Efficiency High Line Loss, Serious Electricity Theft Difficulty in Collecting Fees • No IT system supports services. Meter reading, check, and reports are performed manually • No platform handles faults, complaints, and new requirements, affecting business operations • The line loss rate reaches 40%, far more than European and American countries (8%) • Backward electrical infrastructure causes high technical line loss. • 20% users have stolen electricity, causing serious management line loss. • 3 to 4months payment period , and there is a difficulty in collecting fees • There are few business halls, and fees are in arrears Reading start Reading end Payment completion Bill Line loss: 40% Count fees Overdue payment: 1 to 2 months Day1 Day30 Day31 Day45 Day105 The overdue payment may even reach 135days if customers are not at home during meter reading.

4. Thinking: Theft Prevention and Fee Collection Are the Key Short-Term Solution Medium- and Long-Term Development Reducetechnical line loss Enhance power supply quality. • Reduce management line loss. There is a 20% to 30%reduction. • Prevent theft and reduce line loss. • Change power infrastructure. • Use a pre-payment solution to prevent overdue payment. Short-term capital gains can be used as medium- and long-term investments. • Accelerate fee collection. Ensure basic power supply and power supply of VIP users when there is an imbalance between supply and demand. • Automation process and highly efficient office reduce the OPEX. • Load control • IT-based operation Electric power companies can seize the market when ROI problems such as electricity theft and fee collection are solved.

8. Innovative Product: Open & Unified Management Platform • Unified Management • Centralized managementof electric meters, concentrators, and data acquisition • Remote upgrade and fault location • Capability of managing tens of millions of terminals App CRM Prepayment Line loss analysis Website Billing RESTful Northbound Interface (NBI) Agile Controller Meter data management Meter management • Open Platform • Open architecture with standard NBIs • Improves app integrated development efficiency by 50% Concentrator management Data acquisition control Data Acquisition Protocol Management (DLMS) DLMS Concentrator Meter

9. Benefit 1: Reducing Line Loss by 20% Reducing Line Loss by 20% Shortening Fund Recovery by 2 Months • Reducing management-related line loss: analyzing electricity theftand providing reliable evidence to reclaim the cost of the stolen electricity • Locating technical line loss: locating electric power loss across lines and providing a basis for technical improvement • All the 530,000 users prepay for electricity utilization, which leads to an advanced revenue of US$180 million. + Due to electricity theft Compare power consumption of lines to find out units with high line losses All-round checking Technical line loss

10. Benefit 2: IT-based Process, Lowering Labor Costs by 90% 1.Automatically acquires electric meter data, achieving anti-tampering 4. Checks payment amounts and electricity sales records every day. Operation Center Account Reconciliation Data Acquisition Electricity Sales VEE 3.Unified operation platform and uniform electricity vending portal 2. Analyzes suspicious data based on the VEE engine. VEE: Validation, Estimation, Edit

11. Benefit 3: Highly Recognized by Consumers Improving User Experience Through Multiple Methods • Real-time query of electricity usage • Reminding through multiple modes • Electronic bills via SMS messages, emails, and telephone, etc. • Multi-channel recharge • Counter, website, recharge card, and self-service terminal • Platform-based complaints, fault reports, and account opening • Website and call center, etc. Self-Service Terminal Counter Operations Center End User Payment Website SMS Message/Email/ Telephone Recharge Card Billing

12. Efficient Operations Hi-PLC • 100% Metering Success Rate 86M$/Mouth 530,000+ Agile Controller • Tens of millions of meters managing payment Users 0 • Open architecture with standard NBIs Reduce 90% Arrears Tampering Event • Advanced Metering Infrastructure is such that we will be able to monitor the usage of all the customers at our offices here. • We discover that Huawei is the best company that can give us these services that are required to make our proposed meter roll-out simplest.
