Unbundling

Definition: The process of separating a service into component parts (generation, transmission, distribution, ancillary services, etc) to allow customers to choose where to buy each service separately. Utility unbundling, overseen by regulators, generally requires utilities to ensure that the price of each service accurately reflects the cost of that service (plus a margin for profit).
