February 2014 Appendix I – Waitaki Hydro Electric Power Scheme APPENDIX I – WAITAKI HYDRO ELECTRIC POWER SCHEME The Upper Waitaki Scheme utilises the water of Lake Tekapo, Pukaki and Ohau to generate electricity at five power stations, namely Tekapo A and B, and Ohau A, B and C, before the waters are discharged into Lake Benmore for use at the three mid Waitaki stations; Benmore, Aviemore and Waitaki. There is also potential for further hydro generation downstream of the Waitaki Power Station. The following is a description of the main Waitaki Hydro Power System structures and facilities which are within the Waimate District. Plans showing the core site areas that fall within the Waimate District follow. Rules relating to these areas are contained in Section 11 Utilities. Benmore With a capacity of 540 MW Benmore is the second largest hydro station in New Zealand. Benmore is also the southern end of the HVDC link which joins the North and South Island electricity systems. The dam crest is 823 metres long and 110 metres high. Lake Benmore is a popular boating and fishing lake with attractive lake shore camping and picnicking areas. Aviemore Power Station Aviemore is the middle station in the Mid Waitaki chain. It has a capacity of 220 MW. The Aviemore dam has a total length of 760 metres and a height of 58 metres. Lake Aviemore is a popular recreation area with attractive picnic and camping areas. Waitaki Power Station Waitaki Power Station was the first station to be built on the Waitaki River. The section of the dam between the powerhouse and the North (Waimate District) side of the river acts as a 354 metre long ungated spillweir. The historic powerhouse building on the South (Waitaki District) side of the Waitaki River accommodates 7 generators which have a combined capacity of 150 MW.

INTRODUCTION 1.1 Overview This excursion provides an overview of the geology and tectonics of the Waitaki valley, including some features of its hydroelectric dams. The excursion highlight is Aviemore Dam, constructed in the 1960s across a major fault, the subsequent (mid-1990s – early 2000s) discovery and quantification of late Quaternary displacement on this fault and the resulting engineering mitigation of the dam foundation fault displacement hazard. The excursion provides insights to the nature and expression of faults in the Waitaki landscape, and the character and ages of the Waitaki alluvial terrace sequences.

The Wrybill <I>Anarhynchus Frontalis</I>: a Brief Review of Status, Threats and Work in Progress

BOX36-274, Merivale, Christchurch 8030, New Zealand, e-maih [email protected]. nz Riegen,A.C. & Dowding, J.E. 2003. The Wrybill Anarhynchusfrontalis:a brief review of status,threats and work in progress.Wader Study Group Bull. 100: 20-24. The Wrybill is a threatenedplover endemic to New Zealandand unique in havinga bill curvedto the right.It is specializedfor breedingon bareshingle in thebraided riverbeds of Canterburyand Otago in the SouthIsland. After breeding,almost the entirepopulation migrates north and wintersin the harboursaround Auckland. The speciesis classifiedas Vulnerable. Based on countsof winteringflocks, the population currently appears to number4,500-5,000 individuals.However, countingproblems mean that trendsare difficult to determine. The mainthreats to theWrybill arebelieved to be predationon thebreeding grounds, degradation of breeding habitat,and floodingof nests.In a recentstudy in the MackenzieBasin, predation by introducedmammals (mainly stoats,cats and possibly ferrets) had a substantialimpact on Wrybill survivaland productivity. Prey- switchingby predatorsfollowing the introductionof rabbithaemorrhagic disease in 1997 probablyincreased predationrates on breedingwaders. A recentstudy of stoatsin the TasmanRiver showedthat 11% of stoat densexamined contained Wrybill remains.Breeding habitat is beinglost in somerivers and degraded in oth- ers,mainly by waterabstraction and flow manipulation,invasion of weeds,and human recreational use. Flood- ing causessome loss of nestsbut is alsobeneficial, keeping nesting areas weed-free. The breedingrange of the speciesappears to be contractingand fragmenting, with the bulk of the popula- tion now breedingin three large catchments.

Meridian Energy
NEW ZEALAND Meridian Energy Performance evaluation Meridian Energy equity valuation Macquarie Research’s discounted cashflow-based equity valuation for Meridian Energy (MER) is $6,463m (nominal WACC 8.6%, asset beta 0.60, TGR 3.0%). We have assumed, in this estimate, that MER receives $750m for its Tekapo A and B assets. Forecast financial model Inside A detailed financial model with explicit forecasts out to 2030 has been completed and is summarised in this report. Performance evaluation 2 Financial model assumptions and commentary Valuation summary 5 We have assessed the sensitivity of our equity valuation to a range of inputs. Financial model assumptions and Broadly, the sensitivities are divided into four categories: generation commentary 7 assumptions, electricity demand, financial and price path. Financial statements summary 15 We highlight and discuss a number of key model input assumptions in the report: Financial flexibility and generation Wholesale electricity price path; development 18 Electricity demand and pricing; Sensitivities 19 The New Zealand Aluminium Smelters (NZAS) supply contract; Alternative valuation methodologies 20 Relative disclosure 21 MER’s generation development pipeline. Alternative valuation methodology We have assessed a comparable company equity valuation for the company of $4,942m-$6,198m. This is based on the current earnings multiples of listed comparable generator/retailers globally. This valuation provides a cross-check of the equity valuation based on our primary methodology, discounted cashflow. This valuation range lies below our primary valuation due, in part, to the recent de-rating of global renewable energy multiples (absolutely and vis-a-vis conventional generators). Relative disclosure We have assessed the disclosure levels of MER’s financial reports and presentations over the last financial period against listed and non-listed companies operating in the electricity generation and energy retailing sector in New Zealand.

Waitaki Delta Character Description This unit extends from the Otago Region and Waitaki District boundary at the Waitaki River, approximately 20km along the coast to the northern end of Oamaru. This area is the southern part of the outwash fan of the Waitaki River, and the unit extends northwards from the river mouth into the Canterbury Region as well. The coast is erosional and is characterised by a gravel beach backed by a steep consolidated gravel cliff. Nearer the river mouth the delta land surface is lower and there is no coastal cliff. In places, where streams reach the coast, there are steep sided minor ravines that run back from the coast. The land behind is farmed to the clifftop and characterised by pasture, crops and lineal exotic shelter trees. Farm buildings are scattered about but not generally close to the coastal edge. There are a number of gravel extraction sites close to the coast. 2 In the absence of topographical features, the coastal environment has been identified approximately 100m back from the top of the cliff to recognise that coastal influences and qualities extend a small way inland.
