Electric vehicle batteries slowly lose capacity over time, on average about 2% of range loss per year. But while the battery may not work for driving, it's still capable of energy storage.
A company in Lancaster is taking a problem and turning it into a solution. What looks like a solar farm is actually a charging station. Battery software and algorithms coordinate the energy production and control systems decide when to keep the energy to provide reserves, or release it to the grid during times of peak demand, keeping costs down and electricity flowing.
