"Basically, some of the reports that have been issued are saying there are too many of us and that's inherently inefficient."
ETNZ disputed that suggestion, she said.
A ETNZ report commissioned from UK-based economist professor George Yarrow had shown that while it might look like there were a lot of trusts, that did not equate to being inefficient.
"The generating retail side of the business always blames the distribution side of the businesss for price increases but the data shows it is not the distribution costs that are going up, it's the energy retailing price which is going up."
Sherry said it was "ironic" that the Government had stated its determination to end energy poverty, when it was the Government who was the dominant owner in the energy retailing sector.
With a 51 per cent ownership stake in Genesis, Mighty River Power and Meridian, the Government owned more than 60 per cent of the energy retailing market.
About 80 people from 20 of New Zealand's 22 energy trusts attended the conference, hosted by the Hawke's Bay Power Consumers' Trust.
Sherry said the two-day conference, which wrapped up on Friday, had shown the nation's energy trusts were "very united" in their stand.
"In fact, I think they are pretty fired up and will want to go back to their communities and just really say the communities have to really get behind the trusts and the trusts have to get behind their communities because local ownership is really important."
Community ownership of Hawke's Bay-based energy distribution company Unison, through ownership by the Hawke's Bay Power Consumers' Trust, will later this month provide every household in Napier and Hastings connected to the Unison network with a $220 annual dividend.
