– Scheme development approach

– Hurdles, risks, challenges & opportunities

Hawke’s Bay Catchments

Hawke’s Bay has plenty of water

• Hence extensive flood protection infrastructure assets

But is summer dry

• Has significant seasonal limits when the water is most needed and has highest value

• Long-term drying trend

• Very low river flows in typical summers

• Poorer water quality in lowland areas in part coupled with the low flows issue, part

urban

Has traditionally dealt with not enough water solely through a regulatory

approach

• Traditional planning instruments on their own lack flexibility when dealing with change

(average 8 years)

Field capacity

Water Management in Tukituki Catchment 1 = problem action & inaction

2 = storage pre-feasibility

3 = full feasibility

4 = full scheme operational assessment & final business case

Following 3 years of feasibility studies, examination of 20+ sites for water storage options (large

and small), and extensive stakeholder consultation, the team is on track for determining final

financial viability by June 2014

Environmental benefits

• Direct environmental benefits =

o flushing flows for removing algae

o increased river flows from irrigation return flows

• Offsetting the economic cost of Tukituki plan change =

o the Plan change will improve the river environment through lifting minimum flows,

setting regulatory limits for nutrients

o the RWSS can mitigate the economic impacts as an alternative source of water

• Estimated value $50 to $80 million

Economic Benefits to Hawke's Bay Region from the RWSS

Governed by:

5 Independent Directors

Dedicated RWS sub-committee

• Agribusiness

• Water strategy

• PPP/SPV Commercial Lawyer

• Large Civil Works Engineer

• Cultural & Mana Whenua Advisor

Operational Assessment Scheme delivery

• CEO and RWSS Internal team with assistance from:

Infrastructure Financing Experts

Large Dam Enginering Advisor

Legal (PPP, Securities Law)

Resource Consent / EPA

Scheme Governance

The below comprehensive current and future governance structure will ensure a robust investment

recommendation is made, and contractual frameworks will protect end users against inherent natural monopoly

market power

Scheme Sponsorship

Advisory

• Water supply business that supplies water to users on volumetric charge basis

Farmer do not have to be, but can be, investors

• Business owns and operates storage and distribution infrastructure – supplies

water to farm gate

• Modified BOOT-like model, with SPV operating business for defined concession

period (70 years)

• Assets revert to HBRC (or its successor) for nil compensation at end of

concession period (Iwi & local investors rights carry through)

• Concession deed with HBRC controls many public good aspects of project

• Water users have long term, take or pay, contracts, but some water available

for spot market

Scheme Model

Proposed infrastructure

• One large dam 83m high

• Distribution network for approx 26,000 ha

• River corridors offer alternative distribution

• Approx 80,000 ha in catchment irrigable based on slope

class 0 – 7 degrees

• Depending on land use and consumption very high

reliability water for up to 30,000 ha.

Consenting – 6 May (EPA lodged) to April 15 2014 - Draft Decision

Final Decision 28 May

• Resource consent application for the Ruataniwha Water Storage

Scheme and Tukituki River Catchment Resource Management Plan

Change lodged by way of a joint EPA process (6 May)

• The Plan Change will increase minimum flows and set water quality

D&C Procurement – Feb 2013 (EOI) to Mid 2014 (ready to construct)

Design and construction for the Scheme is being procured through a competitive global process

February 2013

EOI

Strong local & global interest

5 fully formed responses:

Short List

- Boygues & OHL/Hawkins selected

- Significant experience constructing

dams in seismic areas

- Innovative approach to optimise D&C

outcome

- Local involvement promoted through

HB subcontractors

- Underwriting by two of world’s largest

constructors mitigates completion risk

Preparation of Preliminary Information Memorandum/Information Memorandum/

Water User Agreement

Water Access & Uptake

• We currently hold 110 EOI’s, for 44 Mm3 water or 13,000+ hectares

• 47% of the water under EOI, would equate to 27,500 ha on current

metres cube per ha

• Aiming to contract 40 Mm3 water at financial close

• Contractual elements:

Water Price – 23 c take of pay + 3 cents for pressure

35 year contract

CPI inflator with reset mechanism

Farm environmental management plan

• Opportunity for investment via Information Memorandum for eligible

investors (Irrigators/ Hawke’s Bay Investors)

Summary and Recap Scheme development approach

1. Ensure the scheme is part of an overall catchment water strategy

2. Seek to create regulatory security

3. Seek to manage demand and construction risk through a public private

sector alliance

4. Aim to complete final go no go proposition inside 5 years

5. Take a systematic approach – pre feasibility, feasibility and final business

case.

6. To achieve these timeframes – run work-streams in parallel & resource

adequately

Hurdles/risks/challenges/opportunities

1. Workable consent – April – go – no go

> We’ve lost 3 months in our critical path in this work-stream

2. Securing committed revenue from farmers mid year – go - no go

3. Aligning compatible investors and settling the capital structure mid year – go –

no go

> the final capital structure will fold in behind revenue

4. Keeping the build process & critical path aligned

5. RWSS may create new ground for rural water infrastructure in its approach to

> consenting

> procurement

> capital structure

> Bulk water supply business model

Biggest current risk/opportunity = time and momentum
