A number of indicators to measure Energy efficiency (EE) performance was developed by different organizations. The World Energy Council (WEC) has developed a number of indicators for measuring EE performance. The WEC residential EE indicators are; (i) KWh/household, (ii) KWh/Capita, (iii) Solar water heaters/Capita and (iv) emissions in CO2 (Ton)/household. The EE indicators are developed to promote and support development, introduction and implementation of EE policies. Furthermore, the EE indicators are measured (i) to monitor changes in EE and (ii) to allow comparisons of different EE situations. Improving EE, for electric power use in specific, will result in: 1- Better utilization of the available generation capacity to supply more customers, 2- Slow down of the power demand growth, and 3- Reduction of the investment needed for expansion of the electricity sector. In Egypt, there are nine Electricity Distribution Companies (EDCs). Each consists of a number of geographical sectors. Each sector is further divided into districts. The district network consists of distributors, distribution transformers, and LV & M V Lines. Egypt era (Egyptian electric utility and consumer protection regulator agency) has collected and classified database of residential sectors for the nine companies.
There are different log sheets with information about districts and sectors. The main log sheet data for each sector acquired are:
- Monthly KWh & No. of households for each district
- Monthly tariff category KWh & No. of households for each sector
The EE indicators are calculated accordingly using a residential sector hierarchy based on household data, which relates between reliability of Composite Energy Indices (CEI), and the level of sector disaggregation. The residential sector covers all types of residential units. These sectors are further classified based upon nature of rural and urban area. This paper presents a set of EE indicators developed during five years period. The data set is used to analyze the EE indicators of Electricity consumption in different levels in residential sector. The paper compares the EE indicators among the different geographical regions. It discusses the criteria for the peer group selection. The paper presents the comparison on district level, and company level. Furthermore, the paper looks at the possibility of comparing the over all country EE performance to other countries.
