Aurora Energy Limited (Aurora Energy) is seeking Registrations of Interest (ROI’s) from suitably qualified companies (Respondents) who are interested in delivering non-network electricity capacity support in the Upper Clutha network to Aurora Energy.

Electricity to the Upper Clutha area is supplied from Cromwell by two sub-transmission lines operating at 66kV. Each circuit has an autotransformer, located at Transpower’s Cromwell grid exit point (GXP) substation, which connect to the Transpower GXP. This double circuit and transformer arrangement ensure appropriate security of supply to the Upper Clutha area, which is paramount given the importance of electricity to the communities of Wanaka and the surrounding area.

Aurora Energy is seeking solutions to manage the loading on the sub-transmission lines and transformers in contingency situations – where one circuit experiences an outage coincident with peak load, for example. This is to ensure continued security of supply to the Upper Clutha area, and to delay or avoid upgrading the transformers. In turn the non-network support is to provide a more cost-effective solution.

Non-network electricity capacity support could, for example, be distributed generation within the Upper Clutha area and/or demand response. Either could be large-scale, or an aggregation of many small distributed generators, battery systems, or loads. Aurora Energy is open to considering a range of options, provided they meet Aurora Energy’s requirements. Aurora Energy’s requirements are both technical and economic, meaning that the non-network solution must be lower cost than options such as upgrading the transformers.

If you are a supplier of distributed generation, or own and operate, or plan to own and operate, any of the following equipment, connected to the Aurora Energy distribution network, Aurora Energy encourage you to respond to this ROI:
• Backup generators
• Generator(s) continuously supplying electricity, and able to supply at the times Aurora Energy may require non-network support
• Large-scale storage battery system(s)
• Small-scale storage battery systems that can be aggregated on a large scale
• Demand response of any kind that can be aggregated on a large scale (in addition to Aurora Energy’s existing ripple load control)
