Energy markets are not "artificial" markets. Prices, including negative prices, reflect the real-world balance, or lack of it, between supply and demand. Negative prices create incentive for energy storage. Storage providers can generate revenue not only when returning stored energy to the grid but by storing surplus energy in the first place.
