Horizon Power owns transmission and distribution assets across Western Australia.
From 1 July 2021, applicants can apply for access to Horizon Power's covered network in the North West Interconnected System.
On 2 February 2018, the then Minister for Energy announced that all of the interconnected electricity transmission and distribution infrastructure facilities owned by Regional Power Corporation (Horizon Power) in the North West Interconnected System (NWIS) be covered under the Electricity Networks Access Code 2004 (Access Code) commencing 1 January 2020.
This decision is available here and defines Horizon Power’s covered network as follows:
The Minister for Energy has since amended the Access Code to extend the coverage commencement date to 1 July 2021.
The Western Australian State Government is presently implementing a new light-handed regulatory regime which will cover the access and use of certain covered electricity networks in the Pilbara region of Western Australia (Pilbara Electricity Reforms) including Horizon Power’s network in the NWIS.
The Pilbara Electricity Reforms involves the development of a new Pilbara Networks Access Code which, when enacted, will be applied to Horizon Power’s covered network in place of the Access Code. The Pilbara Electricity Reforms are also working to establish an Independent System Operator to maintain power system security in the NWIS.
For more information, please visit Pilbara Electricity Reforms and the Electricity Networks Access Code - Coverage Application.
From the coverage commencement date of 1 July 2021, customers who consume 1,200MWh or more of electricity per year at each exit point (being the point where your property or business is connected to Horizon Power’s covered network) may choose their own retailer. These customers are referred to as “contestable customers”.
At this stage, how we determine who is a contestable customer (i.e. how the 1,200MWh or more of electricity per year is calculated) has not been finalised by the Western Australian State Government.
