For most Perth homes on the Western Power network, Synergy is the main residential electricity retailer, so there may be little choice of electricity provider. Perth households can generally compare several gas retailers, such as Alinta Energy, Kleenheat and other providers operating in the area, by checking rates, supply charges, discounts and contract terms. If you have solar, compare feed-in tariffs with the plan’s usage charges rather than focusing on the credit alone. Check current offers with each retailer and use the Energy Made Easy website to compare available plans for your address.
