The Nigerian Electricity Regulatory commissions provides a range of customer who fall under tariff classes which the Discos bill on a monthly basis and periodically for customers with prepaid meters. The classes are divided between residential customers, commercial customers, industrial customers, government agencies, religious bodies and street lights.
The classes are further divided into two main groups, the Maximum Demand Customers (MD) and the non Maximum Demand Customers (Non-MD). The major difference between MD and Non-MD customers is that the MD customers have their own individual transformers. For example a bank or estate with a dedicated transformer. Unlike Non-MD customers who share transformers with communities. Non-MD customers typically pay higher Fixed charges.
