America will not be constructing sufficient transmission traces to attach regional energy networks. The deficit is driving up electrical energy costs, lowering grid reliability, and hobbling renewable-energy deployment.
On the coronary heart of the issue are utility corporations that refuse to pursue interregional transmission initiatives, and generally even impede them, as a result of new initiatives threaten their income and disrupt their {industry} alliances. Utilities can stall transmission enlargement as a result of out-of-date legal guidelines sanction these corporations’ sweeping management over transmission improvement.
As we more and more electrify our properties, transportation, and factories, utility corporations’ selections about transmission could have big penalties for the nation’s economic system and well-being. About 40 companies, valued at a trillion {dollars}, personal the overwhelming majority of transmission traces in the USA. Their grip over the spine of U.S. grids calls for public scrutiny and accountability.
Many Traces, Secure Energy
Excessive-voltage transmission traces transfer giant quantities of vitality over lengthy distances, linking energy technology to consumption. A transmission community incorporates webs of connections, which create a dependable, redundant power-supply system of large scale.
At any given time, hundreds of energy crops provide simply sufficient vitality to transmission networks to fulfill demand. The foundations that orchestrate the motion of electrical energy by way of this community decide who generates energy, and the way a lot. The aim is to maintain the lights on at a low value by using an environment friendly mixture of energy crops.
Constructing extra transmission will increase the capability and connectivity of the system, permitting new energy crops to attach and extra energy to stream between transmission networks. That is
why utility companies are not embracing transmission enlargement. They don’t need their energy crops to face competitors or their regional alliances to lose management over their networks.
Enlargement can open alternatives for brand spanking new power-plant and transmission builders to undercut utility corporations’ income and take management over the foundations that form the {industry}’s future. Utility corporations are prioritizing their shareholders over the general public’s want for cleaner, cheaper, and extra dependable vitality.
Previous Alliances, Previous Know-how
Transmission networks in the USA, which transfer alternating present, have been constructed over the past century largely by for-profit utility corporations, and to a lesser extent by nonprofit utilities operated by governments and native communities. The traces are usually concentrated round fossil-fuel reserves and inhabitants facilities however are additionally formed by historic utility alliances.
The place utilities agreed to commerce vitality, they constructed adequate transmission to maneuver energy between their native service territories. As utility alliances expanded, transmission networks grew to incorporate new members, however connections to nonallied utilities tended to be weaker.
The results of these generations-old alliances is a U.S. system fragmented into
about a dozen regions with restricted connectivity between them. The areas are distributed throughout three separate and largely remoted networks, referred to as “interconnections”–Jap, Western, and most of Texas.
An October 2023
report from the U.S. Division of Vitality reveals the severity of the issue. Primarily based on research performed by nationwide labs and educational researchers, the DoE calculated that interregional transmission in the USA should develop as a lot as fivefold to keep up reliability and enhance resilience to excessive climate and supply entry to low-cost clear vitality.
The worth of linking regional networks
is widely accepted globally. The European Fee in 2018 set a target for every member nation to transmit throughout its borders no less than 15 p.c of the electrical energy produced in its territories. By the tip of 2022, 23 gigawatts of cross-border connections in Europe have been beneath building or in superior levels of allowing, with much more on the way.
Large Advantages
One of many predominant values of connecting regional networks is that it allows—and is in actual fact
critical for—incorporating renewable vitality. For example, 4 proposed high-voltage lines totaling 600 kilometers alongside the seam of regional networks within the higher Midwest might join no less than 28 gigawatts of wind and photo voltaic. These traces have been on the drafting board for years, however utilities within the neighboring areas haven’t moved them ahead. The price of the undertaking, estimated at US $1.9 billion, could look like a serious funding, however it’s a fraction of what U.S. utilities spend annually rebuilding getting old transmission infrastructure.
Plus, including interregional transmission for renewables can
significantly reduce costs for customers. Such connections permit extra wind and solar energy to stream to neighboring areas when climate circumstances are favorable and permit the import of vitality from elsewhere when renewables are much less productive.

Even with out renewables, higher built-in networks usually decrease prices for customers as a result of they reduce the quantity of technology capability wanted general and decrease vitality market costs. Interregional transmission additionally enhances reliability,significantly throughout excessive climate.
In December 2022, Winter Storm Elliott
disabled power plants and pipelines from North Dakota to Georgia, resulting in energy outages within the South and billions of {dollars} in extra vitality costs throughout the Jap United States. Restricted interregional connections staved off disaster. These hyperlinks moved electrical energy to the place it was most wanted, serving to to keep away from the kind of disaster that befell Texas’s remoted electrical grid the 12 months earlier than, when a deep freeze left tens of millions with out energy for days.
Energy, Revenue, and Management
However from the angle of utility corporations, interregional transmission presents a number of drawbacks. First, constructing such connections
opens the door for competitors who could promote lower-priced energy into their area. Second, utilities make far more cash setting up energy crops than building transmission lines, so they’re reluctant to construct connections that may completely scale back their alternatives for future technology investments.
This comparability of present interregional switch capability and anticipated want exhibits that areas might want to enhance transmission considerably, assuming reasonable load and excessive clean-energy progress.“Nationwide Transmission Wants Examine,” U.S. Division of Vitality
Third, main interregional transmission initiatives are much less financially enticing to utility corporations compared with smaller ones. For bigger initiatives, utilities could should compete in opposition to different builders for the chance to revenue from building. The utility {industry} sponsors
third-party oversight of such initiatives, whereas smaller initiatives are much less scrutinized by the {industry}. Smaller initiatives are easier to pull off and more profitable than the bigger ones, as a result of they want fewer building permits, face much less evaluation by regulators and {industry}, and are constructed by utilities with out competitors from different builders.
Fourth, interregional traces threaten utility corporations’ dominance over the nation’s energy provide. Within the energy {industry},
asset ownership provides control over guidelines that govern vitality markets and transmission service and enlargement. When upstart entities construct energy crops and transmission traces, they are able to dilute utility corporations’ management over power-industry guidelines and stop utilities from dictating selections about transmission enlargement.
Assistance on the Hill
Addressing the transmission scarcity is on the agenda in Washington, however utility corporations are lobbying in opposition to reforms. In September, Senator John Hickenlooper (D-Colo.) and Consultant Scott Peters (D-Calif.) launched the
BIG WIRES Act to pressure utilities or competing builders to construct extra interregional hyperlinks. In 2022, Senator Joe Manchin (D-W.Va.) proposed an approach by which transmission builders suggest initiatives to the DoE. If the company deems a undertaking to be within the nationwide curiosity, federal regulators might allow the undertaking’s building and pressure utilities to pay for it.
In the meantime, the Federal Vitality Regulatory Fee (FERC) is at the moment reevaluating how utilities develop and function transmission networks and
may issue new rules within the coming months. In response, utilities are getting ready litigation that would strip FERC of authority to impose any transmission guidelines in any respect. Their aim is to guard their income and management, even when it comes on the client’s expense.
The U.S. Division of Vitality is pitching in too. On 6 February, the division introduced it will award $1.2 billion to assist new high-voltage transmission traces, on prime of the $1.3 billion it offered final fall to 3 interstate initiatives. Later this 12 months, it plans to unveil its long-awaited
national plan for a large-scale transmission build-out. However with out {industry} assist or tens of billions in further funding from Congress to construct these initiatives, the company’s imaginative and prescient is not going to be realized.
Main With Know-how
New enterprise fashions and applied sciences provide hope. Buyers and entrepreneurs are creating long-distance
direct-current lines, that are more efficient at moving giant quantities of vitality over lengthy distances, in contrast with AC. These DC initiatives sidestep the utility-dominated transmission-expansion planning processes.
Many high-voltage DC (HVDC) transmission traces are already in operation, particularly in
China and Europe. The truth is, DC traces are actually the preferred choice in Europe’s plans to unite the continent.
America lacks a coordinated nationwide planning effort to attach regional networks, however builders could make progress undertaking by undertaking. For instance, future DC traces will join turbines in
Kansas to a neighboring network in Illinois, stretch from Wyoming to California, and move wind and solar energy across the Southwest. Every of those initiatives will transfer renewable vitality from the place it may be generated cheaply to bigger markets the place energy costs are increased, and in doing so they’ll assist bolster the nation’s regional transmission networks.
These pioneering initiatives present that utility corporations in the USA don’t should construct interregional traces, however they do have to get out of the best way. Transmission guidelines written by utilities and their {industry} allies can
obstruct, delay, and add costs to those new initiatives. Streamlining federal and state allowing processes can encourage extra funding, however chopping authorities crimson tape is not going to neutralize utility corporations’ objections to interregional transmission.
U.S. regulators and Congress should press ahead. Promising proposals that promote new enterprise fashions and restrict utility management are on the desk. Our vitality future is on the road.
