In the context of European Union law, a public service obligation or PSO is an obligation imposed on an organisation by legislation or contract to provide a service of general interest within EU territories. PSOs may operate in any field of public service, but postal services, social services, energy, transport and banking are specific sectors where the concept is relevant.[1]
