US electrical energy consumption is rising quicker than it has in many years, thanks partly to the growth in knowledge middle growth, the resurgence in manufacturing, and the growing recognition of electrical autos.
Accommodating that progress would require constructing wind generators, photo voltaic farms, and different energy vegetation quicker than we ever have earlier than—and increasing the community of wires wanted to attach these amenities to the grid.

MIT Expertise Evaluation’s visitor opinion sequence, providing knowledgeable commentary on authorized, political and regulatory points associated to local weather change and clear vitality. You possibly can learn the remainder of the items right here.
However one main drawback is that it’s costly and gradual to safe permits for brand spanking new transmission strains and construct them throughout the nation. This problem has created one of many greatest obstacles to getting extra electrical energy era on-line, decreasing funding in new energy vegetation and stranding others in years-long “interconnection queues” whereas they wait to affix the grid.
Thankfully, there are some shortcuts that would develop the capability of the present system with out requiring fully new infrastructure: a collection of {hardware} and software program instruments generally known as superior transmission applied sciences (ATTs), which may improve each the capability and the effectivity of the ability sector.
ATTs have the potential to radically cut back timelines for grid upgrades, keep away from difficult allowing points, and yield billions in annual financial savings for US shoppers. They might assist us rapidly carry on-line a good portion of the practically 2,600 gigawatts of backlogged era and storage initiatives awaiting pathways to hook up with the electrical grid.
The chance to leverage superior transmission applied sciences to replace the best way we ship and eat electrical energy in America is as near a $20 invoice sitting on the sidewalk as policymakers might ever encounter. Selling the event and use of those applied sciences needs to be a prime precedence for politicians in Washington, DC, in addition to electrical energy market regulators across the nation.
That features the brand new Trump administration, which has clearly acknowledged that constructing higher electrical energy provide and preserving prices low for shoppers are excessive priorities.
Within the final month, Washington has been consumed by the Trump crew’s efforts to check the bounds of government energy, fireplace civil servants, and disrupt the essential workings of the federal authorities. However when or if the White Home and Congress get round to enacting new vitality insurance policies, they’d be smart to select up the $20 invoice by enacting bipartisan measures to speed up the rollout of those revolutionary grid applied sciences.
ATTs typically fall into 4 classes: dynamic line rankings, which mix native climate forecasts and measurements on or close to the transmission line to soundly improve their capability when circumstances enable; high-performance conductors, that are superior wires that use carbon fiber, composite cores, or superconducting supplies to hold extra electrical energy than conventional steel-core conductors; topology optimization, which makes use of software program to mannequin fluctuating circumstances throughout the grid and establish essentially the most environment friendly routes to distribute electrical energy from second to second; and superior energy circulation management gadgets, which redistribute electrical energy to strains with out there capability.
“This may enable utilities to earn a revenue for saving cash, not simply spending it, and will save shoppers billions on their electrical energy payments yearly.”
Different international locations from Belgium to India to the UK are already making large-scale use of those applied sciences. Early initiatives in the USA have been remarkably profitable as effectively. One current deployment of dynamic line rankings elevated capability by greater than 50% for less than $45,000 per mile—roughly 1% of the worth of constructing new transmission.
So why are we not seeing an explosion in ATT funding and deployment within the US? As a result of regardless of their potential to unlock Twenty first-century expertise, the Twentieth-century construction of the nation’s electrical energy markets discourages adoption of those options.
For one factor, beneath the present regulatory system, utilities typically earn a living by passing the price of massive new developments alongside to clients (incomes a hard and fast annual return on their funding). That comes within the type of increased electrical energy charges, which native public utility commissions usually approve after energy corporations suggest such initiatives.
Which means utilities have monetary incentives to make giant and costly investments, however to not save shoppers cash. When ATTs are put in instead of constructing new transmission capability, the smaller capital prices imply that utilities make decrease income. For instance, utilities may earn $600,000 per 12 months after constructing a brand new mile of transmission, in contrast with about $4,500 per mile yearly after putting in the gear and software program mandatory for line rankings. Whereas these state regulatory companies are tasked with making certain that utilities act in the very best curiosity of shoppers, they usually lack the required data to establish the very best strategy for doing so.
Overcoming these structural boundaries would require motion from each state and federal governments, and it ought to enchantment to Democrats and Republicans alike. We’ve already seen some states, together with Minnesota and Montana, transfer on this course, however coverage interventions to this point stay inadequate. In a current paper, we suggest a brand new strategy for unlocking the potential of those applied sciences.
First, we advise requiring transmission suppliers to make use of ATTs in some “no regrets” contexts, the place potential downsides are minor or nonexistent. The Federal Vitality Regulatory Fee, for instance, is already contemplating requiring dynamic line rankings on sure extremely congested strains. Given the low price of dynamic line rankings, and their clear profit in instances of congestion, we consider that FERC ought to rapidly transfer ahead with, and strengthen, such a rule. Likewise, the Division of Vitality or Congress ought to undertake an effectivity commonplace for the wires that carry electrical energy across the nation. Yearly, roughly 5% of electrical energy generated is misplaced within the transmission and distribution course of. The usage of high-performance conductors can cut back these losses by 30%.
As well as, federal companies and state lawmakers ought to require transmission suppliers to guage the potential for utilizing ATTs on their grid, or present help to assist them achieve this. FERC has just lately taken steps on this course, and it ought to proceed to strengthen these actions.
Regulators must also present monetary incentives to transmission suppliers to encourage the set up of ATTs. Probably the most promising strategy is a “shared financial savings” incentive, resembling that proposed within the current Advancing GETS Act. This may enable utilities to earn a revenue for saving cash, not simply spending it, and will save shoppers billions on their electrical energy payments yearly.
Lastly, we should always spend money on constructing digital instruments so transmission homeowners can establish alternatives for these applied sciences and so regulators can maintain them accountable. Creating these methods would require transmission suppliers to share details about electrical energy provide and demand in addition to grid infrastructure. Ideally, with such knowledge in hand, researchers can develop a “digital twin” of the present transmission system to check totally different configurations of ATTs and assist enhance the efficiency and effectivity of our grids.
We’re all too conscious that the world usually faces troublesome coverage trade-offs. However legal guidelines or laws that facilitate the usage of ATTs can rapidly develop the grid and save shoppers cash. They need to be a simple sure on each side of the aisle.
