Dos de las empresas que has puesto ahí cotizan en España, pero no son españolas. Endesa es italiana, como es la otra filial de Enel, Enel Greenpower.
A public utility (usually just utility) is an organization that maintains the infrastructure for a public service (often also providing a service using that infrastructure). Public utilities are subject to forms of public control and regulation ranging from local community-based groups to state-wide government monopolies.
The term utilities can also refer to the set of services provided by these organizations consumed by the public: electricity, natural gas, water, and sewage. Telephone services may occasionally be included within the definition.
En mi opinión hay más utilities cotizando en España. Están por ejemplo Enersis, Endesa Chile, Electrobras.
