From mountain-top wind turbines in Norway to rooftop solar panels in Australia, renewable energy is flooding into power networks like never before. Because the output from these new sources fluctuates with the changing winds and the movement of the sun, they often deliver more electricity than grids can absorb, leading to the curious phenomenon of “negative” power prices.
For sure. I’m expecting that even with significant storage, a cost-optimal system will still need to curtail generation some of the time though.
