Northern Electricity Distribution Company of Ghana (NEDCo)
NEDCo is a wholly owned subsidiary of the Volta River Authority (VRA) responsible for the distribution of electricity in the northern part of Ghana. Its current operations cover about 64% of Ghana’s geographical area and is the sole distributor of electricity in the now Upper East, Upper West, North East, Savannah, Northern, Bono, Bono East, and parts of Oti, Ashanti, and Western North regions.
Grid Electricity Purchase, Sales and Losses Incurred by NEDCo (GWh)
The losses designate the difference between the purchases NEDCo conduct from GRIDCo and the electrical energy it is able to sell to its customers. The losses consist of technical and commercial losses. The first indicate losses as a result of e.g. inefficiencies in the grid. The latter arise from costumers not paying for the entirety of the electricity consumer for example through mistakes in the bills, failure to pay or illegal power tapping.
Percentage (%) Electricity Distribution Losses
The percentage of distribution losses (commercial and technical) by NEDCo in regard to the total energy purchased in Ghana. The share has seen a sharp increase since 2010. Although, in recently it has been on the decline again in 2020 still 27.2% distribution losses were recorded. To compare: for the world in the year 2014 the percentage of both transmission and distribution losses to the total electricity produced was just above 8.2% and for sub-Saharan Africa (excluding high income) for that same year not more than 12%.
NEDCo Electricity Interruption Duration
NEDCo system interruption duration is measured by the average duration of interruptions recorded for the distribution system during an operational year. The regulatory benchmark for average duration of outage permitted by year in an operational area varies.
While for rural areas the regulatory benchmark of 144 hours has in that period never been surpassed, both urban and metro areas have recorded average durations of interruptions above their respective threshold of 72h and 48h. While the value for the urban areas has since 2018 dropped significantly, the duration of interruptions in metro has rather been on the rise and was even in 2020 with 65h above the benchmark.
NEDCo Electricity Distribution Reliability
NEDCo system average interruption reliability frequency can be measured by the number of times that a customer is interrupted during an operational year. The regulatory benchmark, maximum number of outages permitted per year for metro, urban and rural areas is six (6) times.
NEDCo has not been able to ensure a number of outages below the 6 times permitted in any of the the three areas. In the year 2020 the values were 34, 48 and 51 times for the urban, rural and metro areas respectively. The year 2018 must be noted for a peak in outages in urban areas of as much as 146.
