THIS AGREEMENT is made on Click to enter a date (insert date)

BETWEEN Te Aponga Uira (‘the Principal’)

AND Click to enter text (‘the Contractor’)

AND Click to enter text (‘the Warrantor’)

DEFINITIONS

‘Warranted Works’ All hardware and software in relation to the Avatiu Valley Power Station

New SCADA System Project

‘Warranty Period’ 1 years from the date of Practical Completion of the Contract Works

BACKGROUND

A The Principal has entered into a contract (the ‘Contract’) with the Contractor for carrying out the Contract Works.

The Warranted Works are part of the Contract Works.

B The Contractor has agreed to arrange for the provision of a warranty in respect of the Warranted Works for the

Warranty Period on the terms set out in this warranty.

C The Warrantor has agreed to provide a warranty in respect of the Warranted Works for the Warranty Period on the

terms set out in this warranty.

IT IS HEREBY AGREED

1 The Warrantor warrants to the Principal that the Warranted Works are as required in the Contract. If not otherwise

specified the works shall be in accordance with good trade practice.

2 This warranty shall be in addition to and shall not derogate from any manufacturer’s warranty or any warranty

implied by law or the Defects Notification Period in the Contract, attaching to any part of the Warranted Works.

3 Warrantor’s obligations

3.1

The Warrantor agrees that, if within the Warranty Period the Warrantor is advised by the Principal in writing of any defect

in the Warranted Works for which the Warrantor is liable under the terms of this warranty, the Warrantor will promptly

take steps to remedy the defect.

3.2

Any remedial work which the Warrantor is liable to undertake under this warranty shall be carried out:

(a) To the standard required by the Contract;

(b) In a prompt and timely manner;

(c) Without unnecessary inconvenience to any occupants;

(d) At the Warrantor’s Cost; and

(e) Subject to reasonable access being provided to the Warrantor for the purpose of carrying out the remedial work.


3.3

Where the Cost of replacement of work and/or Materials is out of all proportion to the consequences of the defect, or

where the defect may not be reasonably capable of rectification without substantial expense which is out of all proportion

to the Cost of the Warranted Works:

(a) If the defect is reasonably able to be rectified by repair rather than by replacement, the Warrantor’s obligation

under this warranty shall be only to repair or otherwise make good the defect;

(b) The Warrantor may propose reasonable monetary compensation in lieu of remedying the defect; or

(c) The Warrantor may propose a combination of both repair and compensation.

3.4

The Principal shall consider the Warrantor’s reasonable proposals and the parties shall endeavour in good faith to reach

agreement. Where agreement cannot be reached, the dispute shall be resolved in accordance with clause 7.

4 Failure by Warrantor to perform remedial work

4.1

If the Warrantor fails to promptly, adequately and satisfactorily carry out the remedial work or to propose acceptable

repair or compensation, the Principal may then arrange for the remedial work to be carried out by others.

4.2

The Principal shall first give the Warrantor 10 Working Days notice, or such other reasonable time as agreed by the

Principal, to carry out and complete the remedial work. If the Warrantor does not do so within that time, the Principal may

then advise the Warrantor in writing that the work will be carried out by other Persons.

4.3

In such an event, the Warrantor is not released from its obligations under this warranty, which continue in full force and

effect, except for the defect remedied by the Principal or by another Person contracted by the Principal.

4.4

The reasonable Cost of remedial work carried out by such other Persons including all reasonable Costs of the Principal

shall be paid to the Principal by the Warrantor on demand.

5 Exclusions

The Principal agrees that the Warrantor is not liable for any defect or damage caused by:

(a) Wilful act or negligence of the Principal or any Person other than the Warrantor;

(b) Fire, explosion, earthquake, war, subsidence, slips, faulty materials, or workmanship other than caused by the

defect in the Warranted Works;

(c) Any force of nature which the Warrantor could not have reasonably foreseen;

(d) Any neglect or unnecessary delay by the Principal in giving notice to the Warrantor of a defect in the Warranted

Works becoming apparent;

(e) Design faults, errors, or discrepancies, unless the Warrantor undertook the design of the part of the Warranted

Works that is the subject of the defect;

(f) Use of the Warranted Works by the Principal or any other Person in any manner or for any purpose not being the

intended manner of use or purpose of the Warranted Works;

(g) Failure by the Principal or other Person to maintain the Warranted Works in accordance with good practice and any

manufacturer’s stated or recommended instructions or requirements; or

(h) Fair wear and tear.


6 Assignment

The Principal may assign the benefit of this warranty to any Person.

7 Disputes

Any dispute between the Principal and the Warrantor arising out of this warranty is to be referred to arbitration before a

sole arbitrator. If, within 15 Working Days of notice of dispute, the Principal and the Warrantor cannot agree on a single

arbitrator, either party may request the President of the Arbitrators’ and Mediators’ Institute of New Zealand to appoint an

arbitrator.

IT IS AGREED AS FOLLOWS:

1. THE Materials to which this agreement relates are those described in Schedule A to this agreement, all of which

shall bind and be deemed to have been given or assumed by each of them severally and by both of them jointly.

4. THE Contractor and the Subcontractor agree that they will cause the Materials to be set apart at the Premises and

received any payment from the Principal for such Materials.

extend to the Materials or their proceeds.

(a) Inspect the Materials, and verify or undertake the marking and setting apart of the Materials;

(b) Take possession of the Materials for the purpose of delivery to the Site and inclusion in the Contract Works;

(c) Remove the Materials from the Premises for the purpose of delivery to the Site and inclusion in the Contract

Works; and

and in each case in a manner that does not cause damage to any other property at the Premises. The Bailee shall

take all steps and do all things as shall be necessary to ensure that the Principal obtains access to the Premises

for the purposes of this agreement.

17. THE Bailee shall not, except as permitted in clause 5, remove or cause or permit the Materials to be moved from

the Premises. The Bailee shall nevertheless be responsible to the Principal for any loss or damage thereto and for

any costs of storage or handling.

18. THE Bailee shall, when required to do so by the Contractor or the Principal, arrange for the transportation of the

Materials to the Site. Such transportation shall be at the cost of the Bailee in all things including loading, unloading,

and freight.

19. WHERE the Materials are not insured under the construction policy provided in accordance with 8.3.1

or 8.8.1 of the Contract, the Bailee shall, at its expense:

(a) Effect a material damage insurance policy covering all of the Materials subject to this agreement in the name

assets, or undertaking, it will obtain written confirmation from the chargee or mortgagee that the charge or the

mortgage over such property, assets, or undertaking does not extend to the Materials once they have been paid for

by the Principal or the Contractor (as applicable).

23. NOTHING in this agreement shall be deemed to limit, waive, or affect the Engineer’s powers under the Contract to

order the removal from the Site or the Premises of Materials which are not in accordance with the Contract and the

substitution by the Contractor at its own risk and expense of proper Materials. Nothing in this agreement shall be

deemed to limit, waive or affect any other powers conferred on the Engineer and/or the Principal under the

Contract.

1 Scope and General

1.1 Overview

The Government of the Cook Islands has embarked on the introduction of local renewable power

generation in its consumer base. The Cook Islands government wishes to achieve a target of 50%

renewable energy generation by 2015 and 100% by 2020. The main source of renewable energy will

be solar power in the form of photovoltaic cells.

The existing power station on the island of Rarotonga contains seven diesel gen-sets ranging from

0.6MW to 2.7MW. There is an additional 0.8MW hire set. A number of these are reaching the end

of their useful life. The power station is to be extended with the addition of three new, 1.6MW

diesel generators. The oldest of the existing generators will be decommissioned first, with the

remaining following as appropriate.

As part of the upgrade a new SCADA system is required to provide better monitoring and control

of the generators and feeders as well as providing for the new PV generation rapidly being installed

on the network.

A new 960kWp solar array has recently been commissioned near the airport, feeding directly into

the 11kV distribution network, with further generation planned in the near future either by TAU or

by the private sector. There are also incentives for customers to install their own solar generation,

which is limited to 2kW per household.

The diagram below is a high-level view of the proposed SCADA system and its interfaces:

1.3 Stage One – Airport PV Integration and Power Station Existing Equipment Migration

The immediate aim is to provide a new SCADA system that will enable remote control and

monitoring of the new airport 960kWp PV installation, as well as existing equipment at the Power

Station.

The recently completed solar plant at the airport has a number of interfaces, such as the 11kV

switchgear, cluster controller, LV switchboard and an RTU. These will be monitored and the

output from the solar plant controlled via the new SCADA system.

The existing ComAP generator controllers and GE Multilin electrical protection relays will also be

connected to SCADA.

Once this stage is complete, it will allow remote monitoring and control of all of the 11kV power

generation on the island.

A historian will also be included in the initial phase, which will store power-system data for later

analysis and trending. Refer to drawing 214.035-E1000_01.

1.4 Stage Two – New Gensets

The three new 1.6MW generators controllers will interface with the SCADA system. New

protection relays and ancillary equipment associated with the new generators will be integrated into

the new SCADA system. Refer to drawing 214.035-E1001_01.

1.5 Stage Three – Future Plant and Sites

As the amount of solar generation increases, equipment such as a D-UPS system and network

voltage-control resistors will be installed on the network to provide voltage and frequency stability.

These will need to interface with the Expert System that will adjust set points automatically as

appropriate.

In the future equipment will be installed that measures voltage at distribution transformers. This

information is important, as there is a large amount of embedded solar generation being installed by

consumers on the low voltage network. The devices will communicate with SCADA via small-scale

radios or the cellular 2G/3G network. The Expert System will use this information to control load

to ensure the voltage is maintained within tolerance.

Ultimately, the SCADA system will need to be scalable to allow monitoring of generation installed

on the outer islands. The communications link will be via satellite communications or via a cellular

network. Refer to drawing 214.035-E1002_01 and 02.

2.3.3.5 HMI Configuration Software

The Vendor shall provide software allowing the configuration of the HMI displays. This shall be

MS Windows based, intuitive, easy to use and flexible.

A standard library of common power system objects shall be included as well as the facility to

create customised objects. It shall include a feature where global changes can be applied. For

example, a change to an object should automatically follow through to all objects of that type.

It shall be easy to toggle between development mode and test mode. In test mode, the ‘live’

version of the screen under development shall be displayed. Manual forcing of database points

shall be enabled whilst in test mode which will show the effect on the HMI displays.

2.3.3.6 Access Levels

Workstation users shall be assigned to different levels of access, according to the functional

requirements of the users. The workstation levels shall restrict the users to specific functions only

of the control system. The limitations may be functional, operational or geographic.
