Genesis Energy is making moves to meet its promise of producing 95 percent renewable energy by 2035.
The company plans to use profits from Kupe gas field to support a $1.1 billion programme to build solar and wind generation and grid-scale battery storage.
Chief executive Malcolm Johns says it's likely Genesis will meet their target within the coming years.
"We're not starting from a cold start, we have a number of things under way, particularly in the area of solar and wind development. Battery will take us about 18 months to put in place, we're pretty confident."
