A pair of energy consultants are promoting an HVDC interstate transmission-plus-storage project that could complete a link between California and Chicago.
The current project-by-project approach to electricity grid improvements will cost too much and potentially limit development in the future, companies say.
State officials and renewable developers say expanded transmission capacity will be needed to meet energy targets.
The transmission line, originally envisioned as a thruway from Kansas to Indiana, has struggled to gain approval in Missouri and Illinois.
The bill is on its way to a full vote in the state House, where it’s expected to pass, but it faces longer odds in the Senate.
