Renewable Energy Systems Terms & conditions

Renewable Energy Systems Terms & conditions for customers who have a solar system and do not participate in the Renewable Energy Buyback Scheme.

  1. Meter upgrade

    A customer is required to have the necessary meter as determined by Western Power or requested by Synergy and pay for the associated costs if a meter upgrade is required.

  2. Ongoing eligibility requirements for a bi-directional service

    • The supply point is on Western Power’s low voltage (415 volts or less) distribution system; and
    • The supply point is located at a premise with an inverter system rated up to a total of 30kW for single or three-phase connections; and
    • A Western Power approved bi-directional meter is installed at the supply point prior to connecting the generation system; and
    • The customer’s facilities and equipment must comply with the Technical Rules1, the WA Electrical Requirements2 and AS 30003, and
    • The customer’s inverter system must comply with the requirements of AS47774 and the Technical Rules, and must satisfy a technical assessment by Western Power; and
    • The customer has all applicable consents required to install and connect the system to Western Power's network.
  3. Termination

    Synergy can terminate the bi-directional service and the customer must disconnect their system from Western Power’s network if they

    1. no longer occupy the premises;
    2. no longer have the owner's consent to connect the system to Western Power's network (if applicable);
    3. exceed the total maximum inverter capacity; or
    4. fail to perform any obligations imposed on them under these terms and conditions (including, but not limited to, the ongoing eligibility requirements).
  4. Bi-directional service

    The customer will be placed on a bi-directional service offered by Synergy, with a maximum allowable inverter capacity of 30kW. The customer will remain on this service until Synergy and the customer agree otherwise. The customer will pay all network charges and any other charges for the service.

  5. Change of use

    The customer will inform Synergy if they intend to change their use of Western Power’s network including removing or changing their system.

  6. Transfer

    Synergy may transfer to Western Power any or all of its rights and obligations arising out of, or in connection with, this application without the customer’s consent.

  7. Network access charges

    If a change in law occurs Synergy may charge the customer and the customer must pay the applicable network charges for the applicable bi-directional service to the extent necessary to place Synergy in the position it would have been if it had not been for the change in law.

    If a change in network access tariffs occurs, or a new network access tariff is imposed, Synergy may charge the customer an amount to the extent necessary to reflect that proportion of the effect of the new network access tariffs or change in network access tariffs which Synergy estimates in good faith is fairly attributable to or payable by the customer.

  8. Liability for damage

    The customer is responsible for their system and its use. Without limiting their obligations in any way, the customer must install adequate protection devices, as approved by Western Power, to protect their system from faults (including without limitation, power surges) on the Western Power network. The customer agrees that Synergy will not be liable for any loss, damage or injury that may be caused by the customer’s system or its use, or by the customer’s failure to install adequate protection devices.

    Synergy will not be liable to the customer for any consequential or indirect loss or for any business interruption loss, lost profits, loss of an opportunity or the customer’s liability to third parties under a contract or otherwise arising from, or in connection with, a breach of any obligation imposed on the customer under these terms and conditions, the negligence of Synergy or any other legal theory.

    The customer is liable for, and must indemnify Synergy against any loss or damage caused by, consequent upon or arising out of or in connection with any failure to perform obligations imposed on the customer under these terms and conditions or any intentional, reckless or negligent acts and omissions by the customer or any person acting on the customer’s behalf.
