Energy Australia says the NEG is not inherently pro-coal.

State and territory leaders will soon vote on the Government's National Energy Guarantee (NEG), but the policy is still dogged by accusations it is anti-coal, or pro-coal, depending on the critic.

“From an industry perspective, the National Energy Guarantee is neutral, we do not see it as anti-coal or pro-coal,” Energy Australia's energy boss Mark Collette said.

Mr Collette warned that if the Government decides to subsidise a new coal-fired plant, Energy Australia's own planned $400 million gas power plant, Tallawarra B, would not be viable.

“The new power station provides really good capacity into the New South Wales market but, if there is going to be Government-funded coal power stations coming in or other changes of that nature, it does mean that this one probably would not happen,” he said.

“Effectively, the Government will crowd out the scheme.”

The current NEG framework allows future governments to ramp up emissions targets beyond the current 26 per cent reduction target.

Some Coalition backbenchers are concerned that this would lead to more renewable energy investment over fossil fuels.

“Certainly, the emissions dial can be dialled up and down according to the governments of the day, but we see that as appropriate,” Mr Collette said.

“The whole reason we have governments is to implement policies, so that people will vote them in, they will take the choices and then we will deliver.”
