Energy Audit -Ethiopia

 How to do Energy Audit in Ethiopia

What is Energy Audit ?

"The verification, monitoring and analysis of the use of energy and submission of technical report containing recommendations for improving energy efficiency with cost-benefit analysis and an action plan to reduce energy consumption." 

Recently there are many activities to create awareness for the Efficient use of Electricity and Energy saving equipments . The ethiopia Energy Authority now changed to :-  Petroleum and Energy Authority is the main responsible body for control and audit of energy and also for licensing procedures . 

Steps 

1. Get professional "Energy Audit " training - The informaiton form the newsletter suggess for trainig to be given in AAUit , however there is still not clear . 
2. Get Professional Competency Certificate , also read 2010 version here

This certificate is for justifying that you have the required education and skills for the minimum requirement to be able to do Electrical related works . This is different form business license.

  3. Get Electromechanical license - Whether  you are Ethiopian or Company planning to work in Electrical installations, Electromechanical works or To work as an association of experts in Ethiopia you have to have Electromechanical license.The detail requirement and full information can be obtained from this website. 

The application procedure is found in Eservices -https://www.eservices.gov.et/register

    4.Get proper equipments -
Electrical Equipments 

For measuring the electrical parameters the following instrumentation are included:

1. Ammeter: measures the current absorbed by motors/machines.
2. Voltmeter: measures the voltage or voltage drop in the grid or electrical circuits.
3. Watt-meter: measures instant power demand of motors/ machines or the power
performance of generators.
4. Cosö-meter: measures the power factor or monitors the rectification devices.

Temprature Measuremnt

a) Resistance Thermometer Detectors (RTD): One of the most technologically-advanced instruments with internal signals for calibration and resetting and a high level of accuracy.

 b) Thermocouples: Widely used and not expensive, covering a wide range of temperatures, from a few degrees up to 1000 °C and are usually portable. They need frequent calibration with specialized instruments. Their main disadvantage is that they have a weak signal, easily affected by industrial noise.

 c) Thermistors: Used as permanent meters and are of low cost and have an automatic resetting capability.

 d) Infrared thermometers: Measure temperatures from a distance by sensing the thermal radiation. They sense “hot-spots” and insulation problem areas. Portable and easy to use, but with limited accuracy.

DGA - Dissolved Gas analysis - Once proper sampling is achieved, gases are analyzed by the gas analyzer and the percentage of the exhaust gases in CO, CO2, O2, SO2, NOx, CxHx is determined through built-in algorithms. Modern gas analyzers are fully automatic so that when the proper sample is taken, the boiler efficiency and the percentage of the above mentioned gases are shown on the display of the gas analyzer (CRES, 2000).
