Advanced grid tech gets a $1.9B DOE boost

The Department of Energy is putting $1.9 billion toward 31 projects across 26 states to upgrade the power grid, part of a program called SPARK. Utilities involved are matching that with $3.35 billion of their own money, for a total of $5.25 billion in grid upgrades. The money pays for newer transmission cables that carry more electricity than standard lines, plus sensor systems that measure how much power a line can safely carry at a given moment, called dynamic line rating. Both let utilities move more electricity through existing lines instead of building new towers.

Utilities receiving grants include American Electric Power, CenterPoint Energy, Duke Energy, Eversource Energy, Rocky Mountain Power, and PPL Electric Utilities, along with several public power utilities and rural electric cooperatives in Arizona, New Mexico, and North Carolina. Two of the largest awards, $250 million each, went to projects in Colorado and Oklahoma meant to link the country's Eastern and Western power grids so they can share electricity more easily.

For homeowners, this is grid-scale infrastructure news rather than something that changes what's available for your own house right now. But a stronger, less congested grid can mean fewer strains during high-demand periods and, over time, could help hold down the cost increases utilities pass on to customers when they build expensive new infrastructure. Since these technologies let utilities get more capacity out of lines they already have, backers argue it's a cheaper path to a more reliable grid than building everything from scratch.
