"The major drawback with the Parliamentary Commissioner's report and its analysis is that it focuses on whether solar power operates at the very coldest half-hour of the coldest day in winter. It rightly concludes that it doesn't, but it wrongly concludes that this is critically important. What is important to understand is that energy can be stored for later use and meeting peak demand is neither the critical problem, nor the problem for one technology to solve in New Zealand's electricity system"

"The focus on peak demand is also misleading. The fact the majority of New Zealand's electricity system is hydro based means we have a much larger margin or excess of peak generation capacity than many other power systems. For example, in 2011, the country's total installed generation capacity was around 47% greater than national peak electricity demand. This includes a mix of generation options to meet peak demand and the majority of it is hydro"
