Mercury 18c Buy Back offer:
Application: This Harrisons offer is available if you install a new Harrisons Solar PV system and are either an existing electricity retail customer with our exclusive energy provider and not already on a fixed or minimum term agreement, or a new electricity retail customer joining our exclusive energy provider on a 24 month fixed Term.
Term: The Term starts at the end of any “cancellation period” that applies to you, when your power services have been connected with our exclusive energy provider, or from the date of the Agreement, whichever is later. The special 18 cent per unit buy back rate will be applied for the Term or until you terminate the services provided under this Agreement, in accordance with the terms below.
Exit fees: If during the Term of your agreement, you decide to switch your power to another supplier or terminate the power services (including the electricity buy back) early, we’ll need you to pay an exit fee of $150. You won’t be required to pay this exit fee where you switch to another provider or otherwise terminate as a result of material changes made by us to these Terms and Conditions, or our Power and Reticulated Gas Terms. If during the Term you move properties or to a different town or city, your energy pricing may be different at your new address. If you no longer have a Harrisons Solar PV system at your new address we will not charge you the exit fee. There is no exit fee if you switch gas providers.
Export meter: If you do not have an export meter installed at your premises at the time you apply to us to export surplus electricity into the network, we will arrange for an appropriate export meter to be installed. There will be no charge for this meter installation.
