Power firms have been sent one more high-level message concerning using the emissions trading scheme as an explanation to increase prices, when it is not essentially warranted.

Some firms have signaled retail price increases after July 1, as a consequence of the ETS coming mostly into effect, while others have not.

Power corporations in the retail market in New Zealand generate their energy from a varying combination of renewable and non-renewable sources, which means that a few will have heavier financial responsibilities than others under the system.

Prime Minister, John Key said that Genesis Energy, which operates the emissions-heavy coal and gas fired, Huntly Power Station and was at majority exposed of all suppliers to the ETS, had not specified a post July 1 price rise.

Contact Energy is placing prices up a standard of 3.2%, due to the ETS and in the Dunedin region, the percentage price rises were in double numbers.

Mr. Key said that cannot be taken as a justification, and for a firm to hold emissions responsible to increase prices is much of a substance that does not hole any importance.

In addition, he cautioned firms to not to raise prices taking help of the missions trading scheme, as it is not justifiable.
