America will not be constructing sufficient transmission traces to attach regional energy networks. The deficit is driving up electrical energy costs, decreasing grid reliability, and hobbling renewable vitality 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 Utilities can stall transmission growth as a result of out-of-date legal guidelines sanction these corporations’ sweeping management over transmission growth.
As we more and more electrify our properties, transportation, and factories, utility corporations’ selections about transmission may have big penalties for the nation’s financial system and well-being. About 40 firms, 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, Steady Energy
Excessive-voltage transmission traces transfer massive quantities of vitality over lengthy distances, linking energy era to consumption. A transmission community comprises webs of connections, which create a dependable, redundant power-supply system of large scale.
At any given time, hundreds of energy vegetation provide simply sufficient vitality to transmission networks to satisfy demand. The foundations that orchestrate the motion of electrical energy via this community decide who generates energy, and the way a lot. The purpose is to maintain the lights on at a low value by using an environment friendly mixture of energy vegetation.
Constructing extra transmission will increase the capability and connectivity of the system, permitting new energy vegetation to attach and extra energy to circulate between transmission networks. That is
why utility companies are not embracing transmission growth. They don’t need their energy vegetation to face competitors or their regional alliances to lose management over their networks.
Growth can open alternatives for brand 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 Expertise
Transmission networks in the USA, which transfer alternating present, have been constructed during the last 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 ample 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. Based mostly on research performed by nationwide labs and tutorial researchers, the DOE calculated that interregional transmission in the USA should increase as a lot as fivefold to take care of 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 at the least 15 % of the electrical energy produced in its territories. By the top of 2022, 23 gigawatts of cross-border connections in Europe have been underneath building or in superior levels of allowing, with much more on the way.
Large Advantages
One of many foremost values of connecting regional networks is that it permits, and is in reality
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 at the least 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, might seem to be a significant funding, however it’s a fraction of what U.S. utilities spend annually rebuilding growing older transmission infrastructure.
Plus, including interregional transmission for renewables can
significantly reduce costs for shoppers. Such connections permit extra wind and solar energy to circulate 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 shoppers as a result of they reduce the quantity of era capability wanted general and decrease vitality market costs. Interregional transmission additionally enhances reliability,notably 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 fees 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 form of disaster that befell Texas’s remoted electrical grid the yr earlier than, when a deep freeze left hundreds of thousands with out energy for days.
Energy, Revenue, and Management
However from the attitude of utility corporations, interregional transmission presents a number of drawbacks. First, constructing such connections
opens the door for competitors who might promote lower-priced energy into their area. Second, utilities make far extra money setting up energy vegetation than building transmission lines, so they’re reluctant to construct connections that may completely cut back their alternatives for future era investments.
This comparability of present interregional switch capability and anticipated want exhibits that areas might want to improve transmission considerably, assuming average load and excessive clear vitality progress.“Nationwide Transmission Wants Research,” U.S. Division of Vitality
Third, main interregional transmission initiatives are much less financially engaging to utility corporations compared with smaller ones. For bigger initiatives, utilities might need to 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 overview 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 growth. When upstart entities construct energy vegetation and transmission traces, they can dilute utility corporations’ management over power-industry guidelines and forestall utilities from dictating choices about transmission growth.
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 during which transmission builders advocate 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 present reevaluating how utilities develop and function transmission networks and
may issue new rules within the coming months. In response, utilities are making ready litigation that might strip FERC of authority to impose any transmission guidelines in any respect. Their purpose 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 could award $1.2 billion to help new high-voltage transmission traces, on prime of the $1.3 billion it offered final fall to a few interstate initiatives. Later this yr, it plans to unveil its long-awaited
national plan for a large-scale transmission build-out. However with out {industry} help or tens of billions in extra funding from Congress to construct these initiatives, the company’s imaginative and prescient is not going to be realized.
Main With Expertise
New enterprise fashions and applied sciences supply hope. Traders and entrepreneurs are creating long-distance
direct-current lines, that are more efficient at moving massive 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. In reality, DC traces at the moment are 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 project-by-project. For instance, future DC traces will join mills 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 market2s the place energy costs are greater and in doing so, assist bolster the nation’s regional transmission networks.
These pioneering initiatives present that utility corporations in the USA don’t need to construct interregional traces, however they do must 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 slicing 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.
