New Zealand Explores Household Batteries for Grid Services and Compensation
In a pioneering move, New Zealand is exploring a future where households equipped with batteries could provide services to the national grid and earn compensation. This innovative approach could pave the way for a more affordable, collaborative path to decarbonize the country's energy system.
A groundbreaking study, published in the journal Energy & Buildings, suggests that sharing batteries among houses could significantly reduce the required storage capacity, up to 90%. This collective use is far more efficient than individual battery installations. Additionally, batteries can store excess energy generated by solar cells during summer, providing an extra layer of service.
Currently, a trial is underway in the upper Clutha region. Here, batteries are being used to tackle issues stemming from constrained lines. By storing energy and reducing demand during peak times, batteries can help alleviate pressure on the grid. Moreover, they can feed energy back into the grid during periods of low renewable supply, ensuring a steady and reliable power supply.
The collective use of batteries in households could revolutionize New Zealand's energy landscape. By reducing the need for individual storage capacity and providing additional services, this approach could lower costs and accelerate the country's transition to a decarbonized energy system.
