As New Zealand moves towards full decarbonisation and electrification, EDBs are increasingly looking for third parties to help them deliver enhanced network capacity, performance and reliability using non-traditional approaches. These are generically described as non-network alternatives (NNAs), or sometimes non-wires alternatives.
ENA will keep this page up to date with a list of currently open ROIs and RFPs being run by EDBs for NNA support. Where possible ENA will also provide links to information on now-closed ROIs/RFPs as well.
Any questions about an individual ROI/RFP listed here should be directed at the relevant EDB, and ENA makes no guarantees about the accuracy or reliability of this information.
