33.Augmentation of the electricity transmission network
(1)Without limiting Western Power’s obligations under the Act, any proposal to augment the electricity transmission network must be consistent with the network planning criteria to the extent that Western Power reasonably believes the network planning criteria are applicable in the circumstances.
(2)Subject to regulation 14, if Western Power believes that it is necessary or desirable to augment the electricity transmission network, then Western Power must consult with any person who is —
(a)a user or who has made an access application; and
(b)in Western Power’s opinion, likely to be materially affected by the proposed augmentation.
Notwithstanding the terms of any access agreement, an obligation on Western Power to provide access services or to ensure service quality parameters in relation to the electricity transmission network is to be read and construed as an obligation to use all reasonable endeavours to provide those services or ensure those parameters.
35.Force majeure and interruption
(1)A force majeure event in respect of a party to an access agreement or a person to which these regulations apply means any event outside the party’s control, including —
(a)any act of God, lightning, earthquake, storm, fire, flood, subsidence, land slide, mud slide, wash‑out, explosion or natural disaster;
(b)any insurrection, revolution or civil disorder, act of public enemies, malicious damage, sabotage, vandalism, war (whether declared or undeclared) or a military operation, blockade or riot;
(c)any determination, award or order of any court or tribunal, or any regulatory authority or the award of any arbitrator;
(d)any act or omission of government or any government or regulatory department, body, instrumentality, ministry, agency, fire brigade or any other authority other than Western Power or the user (including restraint, expropriation, prohibition, intervention, direction or embargo);
(e)any inability or delay in obtaining any governmental, quasi‑governmental or regulatory approval, consent, permit, licence or authority;
(f)any industrial disputes of any kind, strike, lock‑out, ban, limitation or other industrial disturbances;
(g)any significant plant or equipment failure which could not have been avoided by the exercise of good electricity industry practice;
(h)where the person is party to an access agreement, any act or omission of any person with facilities connected to the electricity transmission network which frustrates the party’s ability to perform its obligations under the access agreement;
(i)any application of any law of the Commonwealth, any Commonwealth authority, the State, any State authority or any local government.
(2)If a user, Western Power or a person who makes an access application (called the “affected person”) is unable wholly or in part to perform on time and as required any obligation under the access agreement or these regulations (other than an obligation to pay money) because of the occurrence of a force majeure event, then, subject to this regulation, that obligation (called the “affected obligation”) is suspended to the extent that and for so long as the affected person’s ability to perform the affected obligation is affected by that force majeure event.
(3)Without limiting subregulation (2), Western Power’s obligation to transfer electricity to or from a connection by means of the electricity transmission network or provide an access service is suspended during any period that the transfer of electricity to or from that connection or the provision of the access service in respect of that connection is interrupted or curtailed under regulation 25 or regulation 29 to the extent of the interruption or curtailment.
(4)Subject to subregulations (5), (6) and (7), if a force majeure event occurs, then the affected person must —
(a)notify any person who in the affected person’s reasonable opinion is likely to be adversely affected by the suspension of the affected obligations; and
(b)use reasonable endeavours (including incurring any reasonable expenditure of funds and rescheduling man power and resources) to mitigate the consequences and minimise any resulting delay in the performance of the affected obligation.
(5)If an affected person fails to comply with subregulation (4)(b), then the only consequence of that failure is that the period of suspension of the affected obligation is reduced by the period of any delay in the performance of the affected obligation attributable to that failure.
(6)The settlement of a labour dispute which constitutes a force majeure event is a matter which is within the absolute discretion of the affected person.
(7)An affected person is not obliged to incur any expenditure in complying with subregulation (4)(b) if the force majeure event is constituted by a breach of, or failure to comply with, the access agreement by another party to the access agreement or these regulations by another person to which these regulations apply.
36.Effect of access to capacity
By executing or complying with its obligations under an access agreement or making any capital contribution under an access agreement, a user does not acquire any right, title or interest in or to the electricity transmission network.
(1)The term of an access agreement is such term as the parties agree and set out in the access agreement, but in any event must not be less than 3 months.
(2)Subject to the terms of the access agreement, an access agreement with an original term of one year or more may be renewed by the user for a further term equal to the original term —
(a)if the original term is less than or equal to 3 years, then by written notice to Western Power received at least 3 months prior to expiration of the original term; or
(b)if the original term is more than 3 years, then by written notice to Western Power received at least 6 months prior to expiration of the original term,
without the requirement for a further access application.
(3)In assessing whether or not there is a spare capacity, it must be assumed that an access agreement which may be renewed in accordance with subregulation (2) will be renewed in accordance with that regulation until the time for exercising the option to renew contemplated by that regulation has expired without that option being exercised.
38.Contract maximum demand and declared sent‑out capacity
(1)If the user’s access agreement in respect of a connection sets out a contract maximum demand for that connection, then the user must use reasonable endeavours to ensure that the user’s actual demand at that connection does not exceed that contract maximum demand.
(2)The declared sent‑out capacity of a generating unit which is not an embedded generating unit is the capacity of the generating unit to generate and transfer electricity to the electricity transmission network, taking into account any electricity used at the connection.
(3)The declared sent‑out capacity of an embedded generating unit is the capacity of the generating unit to generate and transfer electricity to the electricity transmission network, taking into account any electricity used at the connection or supplied to persons otherwise than through the electricity transmission network.
(4)Subject to subregulation (10), the declared sent‑out capacity for a generating unit is the figure published by Western Power in respect of the generating unit from time to time.
(5)Western Power must publish the declared sent‑out capacity for generating units as at 1 January 1997 or before 31 March 1997.
(6)Subject to the terms of the relevant access agreement, if a user wishes to change the declared sent‑out capacity of a generating unit connected at a connection of the user for a financial year, then the user must notify Western Power in writing of the new declared sent‑out capacity of the generating unit not less than 30 business days prior to the start of the financial year.
(7)If a user does not give a notice in accordance with subregulation (6) in respect of a generating unit connected at one of its entry points prior to the start of a financial year, then, subject to subregulation (10), the declared sent‑out capacity of the generating unit for that financial year is the same as it was for the preceding financial year.
(8)Subject to subregulation (10), the declared sent‑out capacity for a financial year for a generating unit connected at a connection commissioned during the financial year is the figure agreed between Western Power and the user in respect of the entry point prior to electricity first being transferred between the electricity transmission network and the connection.
(9)The declared sent‑out capacity of a generating unit for a financial year set out in a notice given under subregulation (6) must not exceed the declared sent‑out capacity of the generating unit for the immediately preceding financial year without the prior written agreement of Western Power.
(10)Western Power and a user may vary the declared sent‑out capacity of a generating unit connected at a connection of the user for a financial year by agreement.
(1)An access agreement commences on the day it is entered into by Western Power and the user and the term of the access agreement runs from that day.
(2)An access agreement may provide for a later day on which the provision of access services is to commence, and, if it does so, then Western Power is under no obligation to provide access services under that access agreement until that later day.
Part 7 — Enforcement, liability and insurance
(1)If a user fails to observe or perform any of its obligations under an access agreement (in this regulation called a “default”), then Western Power may —
(a)notify the user of the default and require the user to remedy the default;
(b)if the default is a default in the payment of any amount and has not been remedied by the end of the 3rd business day after the notice was given, then disconnect the user’s connections from the electricity transmission network whilst that default is continuing;
(c)if the default is any other type of default and at the end of the 5th business day after the notice was given —
(i)the default has not been remedied; or
(ii)the user has not to the reasonable satisfaction of Western Power commenced to remedy the default or has commenced to remedy the default but is not diligently proceeding to remedy the default,
then disconnect the user’s connections from the electricity transmission network whilst that default is continuing; and
(d)if the default has not been remedied at the end of the 20th business day after the notice was given, then treat the default as a repudiation of the access agreement and terminate the access agreement.
(2)The rights of Western Power under this regulation (except the periods of notice) are in addition to and are not to limit any other rights which Western Power has under an access agreement or any other rights or remedies which it has under any other written law, at law, in equity or otherwise.
(3)Specifically, the imposition by Western Power of a charge under Part 4 or otherwise for the use of any access service other than in accordance with the access agreement does not affect Western Power’s rights under this regulation and is not to be taken as any commitment by Western Power to provide any additional access services.
(4)Termination of an access agreement under this regulation does not prejudice the rights or remedies accrued to either party at the date of termination.
[Regulation 40 amended in Gazette 28 Dec 2001 p. 6719.]
41.Liability, insurance and indemnity
(1)In this regulation —
“direct damage” suffered by a person means loss or damage suffered by the person which is not indirect damage;
“indirect damage” suffered by a person, means —
(a)any consequential loss, consequential damage or special damages however caused suffered by the person including any —
(i)loss of (or loss of anticipated) use, production, revenue, income, profits, business and savings; or
(ii)business interruption,
whether or not the consequential loss or damage or special damages was foreseeable;
(b)in respect of contractual damages, damages which would fall within the second limb of what is known as the rule in Hadley v Baxendale; and
(c)any liability of the person to any other person, or any claim, demand, action or proceeding brought against the person by any other person, and the costs and expenses connected with the claim.
(2)To the maximum extent permitted by law, the only warranties and terms which apply to the provision of access services by Western Power are those expressly contained in an access agreement, and all warranties and terms (except those expressly set out in an access agreement) implied by law, including implied by the provisions of the Trade Practices Act 1974 of the Commonwealth or any legislation (whether Commonwealth or otherwise) to similar effect, on the part of Western Power, do not apply to the provision of access services by Western Power.
(3)If at law, the exclusion of any warranty or term is prohibited, then Western Power’s liability in respect of a breach of such warranty or term, is limited to the maximum extent permitted by law. For example, where any law permits Western Power to limit its liability in respect of a breach of an implied warranty or condition to the replacement or resupply of equivalent goods and services, then Western Power’s liability will be so limited.
(4)Western Power or a user who is negligent, or defaults in respect of its obligations under an access agreement, is liable to the other party (including its directors, servants, consultants, independent contractors and agents) for, and is to indemnify the other party (including its directors, servants, consultants, independent contractors and agents) against, any direct damage caused by, consequent upon or arising out of the negligence or default.
(5)A party to an access agreement who is fraudulent in respect of its obligations to the other party under the access agreement, is liable to the other party for, and is to indemnify the other party against, any direct damage or indirect damage caused by, consequent upon or arising out of the fraud.
(6)Except as provided in subregulation (5), neither Western Power nor any user is in any circumstances to be liable to the other for indirect damage, however arising.
(7)Each user must indemnify Western Power for all liability on the part of Western Power to any customer of the user or any generator of the user (including for direct and indirect damage) which Western Power may suffer because of the provision of or failure to provide access services to the user, except only to the extent that such liability is caused by, is consequent upon or arises out of the negligence of Western Power or the breach by Western Power of any term of the relevant access agreement.
(8)Each user must indemnify Western Power for all liability (including direct and indirect damage) which Western Power may suffer to any third party by reason of the default of that user under these regulations or under the access agreement or the negligence of that user.
(9)The terms of an access agreement may contain additional provisions relating to liability of Western Power and a user, including a cap on liability, the terms of an indemnity on the part of a user to Western Power and the requirement of a user to maintain insurances to the reasonable satisfaction of Western Power.

(5)Subject to subregulation (3), Western Power may amend the process developed under subregulation (4).
(6)Western Power must provide a copy of the process to be adopted in the procurement of any of the ancillary services under subregulation (1) (as amended) to any person who requests a copy.
(1)A user other than Western Power must provide and maintain a bank guarantee in a form and with a bank acceptable to Western Power under which Western Power may draw in aggregate an amount equal to or more than the amount last nominated by Western Power for the purposes of this regulation under subregulation (2).
(2)Subject to subregulation (3), Western Power may from time to time nominate an amount for the purposes of subregulation (1) by written notice given to the user based on a good faith assessment of the credit risk of the user to Western Power.
(3)If —
(a)a user fails to pay to Western Power any amount when due under these regulations or an access agreement; or
(b)a user pays an amount under these regulations or an access agreement which Western Power is subsequently required to disgorge or repay under laws relating to insolvency, the protection of creditors or similar matters,
then Western Power may exercise its rights under the bank guarantee in respect of that amount.
(1)Title to, and risk in, electricity which is transferred to the electricity transmission network passes to Western Power at the time it passes through the relevant connection.
(2)Title to, and risk in, electricity which is transferred from the electricity transmission network passes from Western Power at the time it passes through the relevant connection to the user in respect of the connection.
(3)This regulation does not affect an obligation of the user, arising under Part 4 or otherwise, to pay any charge relating to the transport of the electricity.
[Regulation 44 amended in Gazette 28 Dec 2001 p. 6719.]
45.Assignment of access agreements
(1)A user must not —
(a)assign, novate, declare itself a trustee of, or otherwise dispose of, any of its rights under an access agreement or a grant of access under clause 2 of Schedule 5 to the Act;
