But, she said, what appealed most to customers was Genesis being steady and reliable.
"We're trialling a range of things in solar energy already as a company. And if and when, at the critical moment, where we can deliver advantage, both to our shareholders, our stakeholders and our customers, we will then implement," she said.
"But we are not experimental. We are a high-performing, well-balanced energy company."
