Ngaruroro pumped storage

The New Zealand government has notified that North Island options will be included as part of its business case review of pumped storage sites, with sufficient energy storage capacity to offset dry year risk. Although having less storage capacity than Onslow-Manorburn, the upper Ngaruroro River can be thought of as the North Island equivalent of Onslow. As such, a possible Ngaruroro pumped storage scheme may be be included as part of the review process. A brief outline of the scheme can be found here. This is a draft manuscript, to be submitted for peer review to the Journal of Hydrology (NZ). The published version will have some differences in content. There is no implication of advocacy for the Ngaruroro Scheme. Both positive and negative aspects are indicated as an aid for public input to the business case review.
