Grid (un)locked: Carbon neutral future depends on updating how we make, move and store electricity

In the push to decarbonize the economy throughout the Intermountain West and beyond, the public conversation often centers on wind and solar energy, electric cars, hydrogen power and carbon capture and storage. The grid—the interconnected power plants, transmission lines and control centers that keep the lights on across the country—is the indispensable enabler of this future carbon-neutral electrified world. Yet the grid is often left out of the discussion.
It shouldn’t be.

Influx of Electric Vehicles Accelerates Need for Grid Planning

A new PNNL report says the western U.S. bulk power system can reliably support projected growth of up to 24 million electric vehicles through 2028, but challenges will arise as EV adoption grows beyond that threshold. This study is the most comprehensive of its kind, integrating multiple variables not evaluated before, such as growth in commercial delivery fleets and long-haul trucks, as well as large-scale and long-term EV charging scenarios and strategies.
