Feb. 5 — When state lawmakers deregulated the power business two decades ago, they divided the industry into two sectors with distinct duties: Generators could make and sell electricity and regulated utilities could transmit and distribute electricity. But the utilities, whose profits are capped by regulators, want access to a new business opportunity — battery storage.

Batteries are on the cusp of transforming the Texas power grid by making intermittent power sources such as wind and solar into a supply as dependable as natural gas. Demand for battery storage has been driven by rapidly falling prices and more efficient technology, making it easier to store power for use when wind isn’t blowing or sun isn’t shining.
