Refers to energy provision in which all needed services are provided as a single package, usually by a single provider who provides a single invoice.

While energy provision might appear to be a single service, it actually consists of numerous specific services which are all required before an end-use customer can receive energy. These services include generation of energy, transmission of electricity, distribution from the transmission system, metering and billing, and support functions required to maintain consistent supply.

Prior to deregulation of the energy industry, bundled service was the norm. The same services are still needed, but different suppliers can now provide individual component services.
