The result is that electricity is once again becoming a growth market.
At the same time, the supply side of the grid is also changing rapidly. Renewable generation, especially solar, now represents a growing share of electricity production. Solar power is inexpensive and abundant during midday hours, but production falls sharply after sunset, even as residential and commercial demand remains elevated. This creates widening intraday imbalances between when electricity is generated and when it is actually needed.

Battery storage as the flexibility layer
This changing load profile is one reason modern electricity markets increasingly require flexibility rather than simply more generation capacity. The grid now needs assets capable of absorbing excess energy during periods of oversupply and releasing it rapidly during scarcity events.
