Under the package, consumers were meant to be able to obtain information on their energy consumption and rights, enforced by an energy ombudsman.
As part of their Energy Efficiency Action Plans, member states are also supposed to introduce new technologies like smart meters for use by consumers.
Last week's Council conclusions speak of "providing correct, transparent and user-friendly information so as to change the behaviour of consumers towards energy savings," which are made most effectively with lower energy consumption.
The idea is that by having access to consumption-monitoring devices and simpler bills, consumers will be more aware of their energy expenditure and can change supplier if they want to.
The conclusions highlight the "urgent need" for consumers to compare prices and be able to switch energy suppliers easily, with "special attention" placed on consumers' bills.
A European Commission study found last month that EU consumers could save around €13 billion or €100 per household each year if they were to shop around for energy prices and switch to the cheapest tariff available to them. However, less than one in three consumers actually bother to do so.
Liberalisation of the electricity market will therefore not be as beneficial to consumers as it could be, the study concluded.
Consumers must be "properly trained and educated," according to the energy ministers, who underlined that "the energy bill is one of the most important means of information to the consumer".
In September, the Commission agreed to come up with a definition of energy poverty in a bid to put consumers on the bloc's energy policy agenda.
Over 50 million Europeans are estimated to be unable to pay their energy bills and maintain comfortable living standards.
However, it will be up to member states to set out what can be defined as energy poverty, the ministers said, meaning citizens' rights could be better protected in some member states than others. The Commission will then analyse how member states came up with their definitions.
An EU energy ombudsman
Ways of settling consumer disputes related to energy currently vary amongst member states. Germany, for instance, does not even have an out-of-court dispute resolution mechanism.
To fill these gaps, ministers proposed to establish an EU-wide "independent mechanism" to handle disputes in order to secure "efficient and effective treatment" of out-of-court settlements.
The mechanism could adhere to the model for treating complaints used by the existing European Energy Ombudsman Group, which is made up of ten consumer rights groups and energy companies.
