Western Australia has come up with a strategy to manage the area’s booming rooftop solar market. It includes extended network export payments for electric vehicles, batteries, and promoting new solar systems, which will be installed facing the west side.
The plan is to create a time-varying solar feed-in at a decent rate, which encourages households to store their rooftop solar generation during the daytime and export them in the evening. The basic idea behind it is that it will help to even out the solar duck curve that is currently occurring. Duck Curve showcases the difference between electricity demand and the quantity of available solar energy throughout the day. AEMO and state governments desire to work on cumulative network stability. The idea is also about supporting the expertise in technologies that are essential for the transition.
The state is not alone in the path of searching for ways to manage a flourishing rooftop solar resource so that it can benefit the more significant network than impeding it. Western Australia is presently at the bleeding age of solutions because of the state’s tremendous insights into rooftop solar and its superior position outside NEM. It appeared recently that the government has set up a new record at the least amount of demand.
Authorities to Follow Optimized Approach
“The state of Western Australia is going through a huge energy transformation, with every one in two households expected to have solar panels by the end of 2030,” said State Energy Minister Bill Johnston. At the launch of State’s Distributed Energy Roadmap, Bill Johnston expressed that “They have a challenge that none of the other people are doing.” He also stated, “They have a very high knowledge of distributed energy resources and an islanded network. They can’t rely on other states to support their activities”. But Johnston was optimistic about the forthcoming obstacles and exclaimed that these challenges could also be taken as an advantage.
This implies that the present solar customers will be receiving the REBs until or unless they update their PV systems and add a battery; otherwise, they may need to pay for their meter change. The effort to install the rooftop solar systems with their panels facing west is a fantastic feature of the scheme. The release of a study by the University of South Australia suggested that the nationwide habit of turning a rooftop system to the north was adding the duck curve problem to Australia’s solar saturated network. The DEBs will either change the customer pattern of energy use or offer incentives to convince them to invest in an electric vehicle or battery storage. The rest of Australia will witness Western Australia closely to see how people will react to the change.
Bright Times Ahead
The Chairman of Australia’s Sustainable Energy Department, Ian Porter, said, “Solar Energy Network has recommended changing tariffs to motivate the uptake of batteries by rooftop solar owners to label the duck curve. The new tariff formation can result in customer behavior appropriately adjusting and making the network more flexible and efficient. Solar Energy Network encourages the Government to go ahead and plan for the removal of coal and gas-fired generation so that the transition to the renewables, particularly the introduction of more wind and solar generation, can proceed easily.”
