| Regulatory deferral account balances [member] | en | http://www.xbrl.org/2003/role/label | http://www.xbrl.org/2003/role/link |
| This member stands for regulatory deferral account balances. A regulatory deferral account balance is the balance of any expense (or income) account that would not be recognised as an asset or a liability in accordance with other Standards, but that qualifies for deferral because it is included, or is expected to be included, by the rate regulator in establishing the rate(s) that can be charged to customers. This member also represents the standard value for the 'Regulatory deferral account balances' axis if no other member is used. | en | http://www.xbrl.org/2003/role/documentation | http://www.xbrl.org/2003/role/link |

| Este membro representa os saldos dos diferimentos regulamentares. Um saldo dos diferimentos regulamentares é o saldo de qualquer conta de despesas (ou rendimento) que não seria reconhecido como um ativo ou um passivo de acordo com outras normas, mas que se qualifica para diferimento por estar incluído, ou por se esperar que esteja incluído, pelo regulador de taxas na criação da(s) taxa(s) que pode(m) ser cobrada(s) aos clientes. Além disso, este membro representa o valor padrão do eixo «Saldos dos diferimentos regulamentares» caso não seja utilizado outro membro. | pt | http://www.xbrl.org/2003/role/documentation | http://www.xbrl.org/2003/role/link |
