Ergon Energy teams with SunPower and Sunverge Energy to offer solar plus battery storage for households. It will cut households bills and allow retailers and networks to use “virtual power plants” of pooled household storage, to hedge against rising fuel costs and grid upgrades.
Ergon Energy looks at buy-back of export feed-in tariffs – and offer of battery storage – to shift load away from evening peaks, and save on grid upgrades.
Latest Energex data shows 290,006 households on south-east Qld network have rooftop solar, amounting to a total installed capacity of more than 980MW.
Energex already has 25% of its customers with rooftop solar, but says there is room for more – particularly on businesses and large scale installations.
Queensland network operator Energex has conceded that its century-old business model is under threat from the increased use of rooftop solar, and a growing interest among its 1.3 million consumers to produce and manage their own energy needs. It’s not the only network operator to feel the heat.
