The power supply source service is essential for supplying electricity to homes, businesses, and other facilities. Some of the energy supply service components are:

Power generation: Power generation facilities can be located near or far from electricity end-users.

Electricity Transmission: Electricity transmission involves the movement of electricity over long distances from electricity generation facilities to local distribution systems. This is usually done through high voltage power lines that can carry large amounts of electricity over great distances.

Power distribution: Power distribution refers to the local delivery of electricity to homes, businesses, and other facilities. This is usually done through a network of low-voltage power lines connected to individual transformers, which then distribute the electricity to individual buildings.

Power metering: Power metering refers to the measurement of the amount of electricity consumed by individual customers. This is usually done using electricity meters installed at the customer's location and monitored by the utility company.

Electricity Billing: Electricity Billing involves calculating and collecting payments from customers for the electricity they consume. This includes the cost of electricity as well as various fees and taxes related to energy supply services.

As a whole, energy supply services are critical to the functioning of society and require a complex network of infrastructure and systems to deliver reliable and affordable electricity to customers.
