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.
This is just further spelling out the case for energy storage. It seems like there would be tons of profit potential for just running a grid scale battery storage facility plant- if you can charge at negative wholesale and sell at peak, then you would not only stand to make a profit, but you’d help even out the problem.
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.
