Once one of the largest state-owned providers, now defunct and known as Endeavour Energy.
Integral energy is no longer an active provider in its previous form. In 1995 Integral was formed by a merging of two providers: Prospect and Illawarra Electricity. After this merger, Integral became one of the biggest state-owned providers in the country, providing electricity to 2.1 million customers.
In 2011, the Integral brand was sold to Origin Energy. The distribution networks remained state-owned, but operate under the name of Endeavour Energy.
Could you switch to Integral Energy?
No. There are no options to switch to Integral Energy. The networks are now owned and run by Endeavour Energy.
