The electricity “death spiral” has, for a long time, been a key risk facing electricity generators/distributors globally.
The “death spiral” arises when demand for power declines, due in part to customers taking up solar, leading to higher prices to cover fixed network costs. That is, the more people that take-up solar power, the faster decline in electricity demand, and the more fixed costs must be spread over a smaller volume of electricity, raising costs for everyone else.
