Appendix to Final report on NZ battery gross benefits
PDF, 12MB, 45 pages
This report sets out estimates of gross national benefits for generic pumped hydro storage schemes (referred to as ‘NZ Battery’ options) defined in terms of their storage size (‘tank’), maximum output (‘tap’), location in the North or South Island, and round-trip efficiency. It also sets out estimates of gross national benefits for 3 selected storage options using other technologies including biomass, flexible geothermal and hydrogen/ammonia production, and use.
