The US is just not constructing sufficient transmission traces to attach regional energy networks. The deficit is driving up electrical energy costs, lowering grid reliability, and hobbling renewable power deployment.
On the coronary heart of the issue are utility corporations that refuse to pursue interregional transmission tasks, and typically even impede them, as a result of new tasks 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 Utilities can stall transmission growth as a result of out-of-date legal guidelines sanction these corporations’ sweeping management over transmission growth.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 houses, transportation, and factories, utility corporations’ selections about transmission can have enormous penalties for the nation’s economic 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, Secure Energy
Excessive-voltage transmission traces transfer massive quantities of power 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 vegetation provide simply sufficient power to transmission networks to satisfy demand. The principles that orchestrate the motion of electrical energy by this community decide who generates energy, and the way a lot. The objective is to maintain the lights on at a low price 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 circulation between transmission networks. That is
why utility corporations usually 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.
Enlargement can open alternatives for brand new power-plant and transmission builders to undercut utility corporations’ income and take management over the principles that form the {industry}’s future. Utility corporations are prioritizing their shareholders over the general public’s want for cleaner, cheaper, and extra dependable power.
Previous Alliances, Previous Expertise
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 power, 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
a few dozen areas with restricted connectivity between them. The areas are distributed throughout three separate and largely remoted networks, referred to as “interconnections”–Japanese, Western, and most of Texas.
An October 2023
report from the U.S. Division of Power reveals the severity of the issue. Based mostly on research carried out 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 power.
The worth of linking regional networks
is broadly accepted globally. The European Fee in 2018 set a goal for every member nation to transmit throughout its borders not less than 15 % 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 phases of allowing, with far more on the best way.
Large Advantages
One of many fundamental values of connecting regional networks is that it permits, and is the truth is
essential for, incorporating renewable power. As an example, 4 proposed high-voltage traces totaling 600 kilometers alongside the seam of regional networks within the higher Midwest might join not 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 mission, estimated at US $1.9 billion, could appear 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
considerably cut back prices for shoppers. Such connections permit extra wind and solar energy to circulation to neighboring areas when climate circumstances are favorable and permit the import of power from elsewhere when renewables are much less productive.

Even with out renewables, higher built-in networks typically decrease prices for shoppers as a result of they cut back the quantity of technology capability wanted general and reduce power market costs. Interregional transmission additionally enhances reliability,notably throughout excessive climate.
In December 2022, Winter Storm Elliott
disabled energy vegetation and pipelines from North Dakota to Georgia, resulting in energy outages within the South and billions of {dollars} in extra power prices throughout the Japanese United States. Restricted interregional connections staved off catastrophe. These hyperlinks moved electrical energy to the place it was most wanted, serving to to keep away from the type of disaster that befell Texas’s remoted electrical grid the 12 months earlier than, when a deep freeze left hundreds of thousands 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 rivals who could promote lower-priced energy into their area. Second, utilities make far more cash setting up energy vegetation than constructing transmission traces, so they’re reluctant to construct connections that may completely cut back their alternatives for future technology investments.

Third, main interregional transmission tasks are much less financially engaging to utility corporations compared with smaller ones. For bigger tasks, 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 tasks, whereas smaller tasks are much less scrutinized by the {industry}. Smaller tasks are simpler to drag off and extra worthwhile 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 possession supplies management over guidelines that govern power 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 stop utilities from dictating selections 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 strategy during which transmission builders advocate tasks to the DOE. If the company deems a mission to be within the nationwide curiosity, federal regulators might allow the mission’s building and pressure utilities to pay for it.
In the meantime, the Federal Power Regulatory Fee (FERC) is presently reevaluating how utilities develop and function transmission networks and
could difficulty new guidelines 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 objective is to guard their income and management, even when it comes on the client’s expense.
The U.S. Division of Power 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 tasks. Later this 12 months, it plans to unveil its long-awaited
nationwide plan for a large-scale transmission build-out. However with out {industry} help or tens of billions in further funding from Congress to construct these tasks, 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 traces, that are extra environment friendly at transferring massive quantities of power over lengthy distances, in contrast with AC. These DC tasks sidestep the utility-dominated transmission-expansion planning processes.
Many high-voltage DC (HVDC) transmission traces are already in operation, particularly in
China and Europe. Actually, DC traces are actually the popular alternative in Europe’s plans to unite the continent.
The US 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 community in Illinois, stretch from Wyoming to California, and transfer wind and photo voltaic power throughout the Southwest. Every of those tasks will transfer renewable power from the place it may be generated cheaply to bigger market2s the place energy costs are increased and in doing so, assist bolster the nation’s regional transmission networks.
These pioneering tasks 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
impede, delay, and add prices to those new tasks. Streamlining federal and state allowing processes can encourage extra funding, however slicing authorities pink 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 power future is on the road.
