1 Credible Energy Meter Management Pro s and Con s of deploying different meter types and meter reading technology in Nigeria Presented by: Engineer Abiodun Ajifowobaje CEO - Ikeja Power Distribution Company Riaan Naude Technical Specialist Consolidated African Technologies David Baugh MD Power and Automation Technologies Limited

2 Overview Metering options available: Smart Metering (Automated Meter Reading) Walk-By AMR (Pulse Count) Radio / Mesh Network Technology PLC (Power Line Communications) Cellular Technology (SMS / 3G/ GPRS Communications) Conventional Credit Metering (Electro Mechanical Meters) Legacy Electro Mechanical Meters IR Communications Port Enabled Meters Pre-Paid Metering

3 How many of these do you have?

4 The Problem Due to perceived inaccurate accounts customers do not pay regularly and want pre-paid meters. Accounts are not necessarily inaccurate, but rather a result of a billing & distribution distortion caused by: varying billing cycles Irregular electricity supply results in variations in consumption. Infrequent and limited access to premises Estimation of accounts based on inconsistent history Faulty and obsolete meters

5 The Problem IKEJA DISCO already has good quality Electro- Mechanical meters installed (typically 3million countrywide) Replacing them will come at a huge cost especially if replacement is not necessary

6 Pre-Paid Meters - PRO s & CON s PRO s CON s Upfront payment Reduced need to visit meters Relatively cheap hardware Susceptible to Theft / Fraud - Irregular visits results in bypasses Reliable & Accessible Payment (Vending) should be available 24/7 to the public Vending from non-utility points provide fraud opportunity

7 Smart Metering - PRO s & CON s PRO s CON s Reduced need to visit meters Remote Cut-offs are possible No need for cash vending Susceptible to Theft / Fraud - Irregular visits result in bypasses Increased Capital Outlay Users pay for power after they have used it

8 Conventional Metering - PRO s & CON s PRO s CON s Less susceptible to theft & fraud due to regular visits No need for external cash vending Relatively cheap hardware Possibility of using field billing Need to regularly visit meters to obtain readings Remote Cut-offs not possible Labour intensive reading process Restricted access leads to estimated billing Users pay for power after they have used it

9 The Requirement The solution employed may not be a single strategy. Multiple measuring and reading technologies are often necessary to serve different types of customers / areas

10 The Requirement Whatever solution is installed must be agreeable the the end users Users should be able to trust the results of both the measuring and reading solutions.

11 The Requirement The utility needs to know all the advantages and disadvantages of every solution in order to best manage risk & return on investment.

12 The Solution Deploy technology best suited to the demographic, location and application Devise strategies to strengthen the deployed solutions in the areas where it comes up short or is open to abuse Inspect meters even when the manufacturer claims they are tamper proof or tamper resistant
