There's hesitation around moves to beef up regulations guiding electricity gentailers.
From July, the big four gentailers mustn't give their retail arms better deals on power contracts than independent companies.

"We're asking those gentailers to act in a way that is in opposition to their commercial incentives, and those are - keep supply tight, keep competition out and keep prices high."
