This story is a part of CNBC’s “Transmission Troubles” sequence, an inside take a look at why the growing older electrical grid within the U.S. is struggling to maintain up, the way it’s being improved, and why it is so very important to combating local weather change. See additionally Part 1, “Why America’s outdated energy grid is a climate problem.”
Building new transmission strains within the United States is like herding cats. Unless that course of might be basically improved, the nation can have a tough time assembly its local weather objectives.
The transmission system within the U.S. is previous, would not go the place an vitality grid powered by clear vitality sources must go, and is not being constructed quick sufficient to fulfill projected demand will increase.
Building new transmission strains within the U.S. takes so lengthy — if they’re constructed in any respect — {that electrical} transmission has turn into a roadblock for deploying clear vitality.
“Right now, over 1,000 gigawatts worth of potential clean energy projects are waiting for approval — about the current size of the entire U.S. grid — and the primary reason for the bottleneck is the lack of transmission,” Bill Gates wrote in a current weblog submit about transmission strains.
The stakes are excessive.
From 2013 to 2020, transmission strains have expanded at solely about 1% per yr. To obtain the complete influence of the historic Inflation Reduction Act, that tempo should greater than double to a median of two.3% per yr, in response to a Princeton University report led by professor Jesse Jenkins, who’s a macro-scale vitality methods engineer.
Herding cats with competing pursuits
Building new transmission strains requires numerous stakeholders to return collectively and hash out a compromise about the place a line will run and who can pay for it.
There are 3,150 utility corporations within the nation, the U.S. Energy Information Administration advised CNBC, and for transmission strains to be constructed, every of the affected utilities, their respective regulators, and the landowners who will host a line must agree the place the road will go and easy methods to pay for it, in response to their very own respective guidelines.
Aubrey Johnson, a vice chairman of system planning for the Midcontinent Independent System Operator (MISO), one in all seven regional planning companies within the U.S., in contrast his work to creating a patchwork quilt from items of fabric.
“We are patching and connecting all these different pieces, all of these different utilities, all of these different load-serving entities, and really trying to look at what works best for the greatest good and trying to figure out how to resolve the most issues for the most amount of people,” Johnson advised CNBC.
What’s extra, the events on the negotiating desk can have competing pursuits. For instance, an environmental group is more likely to disagree with stakeholders who advocate for extra energy technology from a fossil-fuel-based supply. And a transmission-first or transmission-only firm concerned goes to learn greater than an organization whose essential enterprise is energy technology, doubtlessly placing the events at odds with one another.
The system actually flounders when a line would span a protracted distance, working throughout a number of states.
States “look at each other and say: ‘Well, you pay for it. No, you pay for it.’ So, that’s kind of where we get stuck most of the time,” Rob Gramlich, the founding father of transmission coverage group Grid Strategies, advised CNBC.
“The industry grew up as hundreds of utilities serving small geographic areas,” Gramlich advised CNBC. “The regulatory structure was not set up for lines that cross 10 or more utility service territories. It’s like we have municipal governments trying to fund an interstate highway.”
This sort of headache and bureaucratic consternation typically stop utilities or different vitality organizations from even proposing new strains.
“More often than not, there’s just not anybody proposing the line. And nobody planned it. Because energy companies know that there’s not a functioning way really to recover the costs,” Gramlich advised CNBC.

Who advantages, who pays?
Energy corporations that construct new transmission strains have to get a return on their funding, explains James McCalley, {an electrical} engineering professor at Iowa State University. “They have got to get paid for what they just did, in some way, otherwise it doesn’t make sense for them to do it.”
Ultimately, an vitality group — a utility, cooperative, or transmission-only firm — will cross the price of a brand new transmission line on to the electrical energy clients who profit.
“One principle that has been imposed on most of the cost allocation mechanisms for transmission has been, to the extent that we can identify beneficiaries, beneficiaries pay,” McCalley stated. “Someone that benefits from a more frequent transmission line will pay more than someone who benefits less from a transmission line.”
But the mechanisms for recovering these prices varies regionally and on the relative measurement of the transmission line.
Regional transmission organizations, like MISO, can oversee the method in sure instances however typically get slowed down in inner debates. “They have oddly shaped footprints and they have trouble reaching decisions internally over who should pay and who benefits,” stated Gramlich.
The longer the road, the extra problematic the planning turns into. “Sometimes its three, five, 10 or more utility territories that are crossed by needed long-distance high-capacity lines. We don’t have a well-functioning system to determine who benefits and assign costs,” Gramlich advised CNBC. (Here is a map exhibiting the region-by-region planning entities.)
Johnson from MISO says there’s been some incremental enchancment in getting new strains authorized. Currently, the regional group has authorized a $10.3 billion plan to construct 18 new transmission tasks. Those tasks ought to take seven to 9 years as an alternative of the ten to 12 that’s traditionally required, Johnson advised CNBC.
“Everybody’s becoming more cognizant of permitting and the impact of permitting and how to do that and more efficiently,” he stated.
There’s additionally been some incremental federal motion on transmission strains. There was about $5 billion for transmission-line development within the IRA, however that is not almost sufficient, stated Gramlich, who known as that sum “kind of peanuts.”
The U.S. Department of Energy has a “Building a Better Grid” initiative that was included in President Joe Biden’s Bipartisan Infrastructure Law and is meant to advertise collaboration and funding within the nation’s grid.
In April, the Federal Energy Regulatory Commission issued a discover of proposed new rule, named RM21-17, which goals to handle transmission-planning and cost-allocation issues. The rule, if it will get handed, is “potentially very strong,” Gramlich advised CNBC, as a result of it could power each transmission-owning utility to have interaction in regional planning. That is that if there aren’t too many loopholes that utilities might use to undermine the spirit of the rule.
What success seems to be like
Gramlich does level to a few transmission success tales: The Ten West Link, a brand new 500-kilovolt high-voltage transmission line that can join Southern California with solar-rich central Arizona, and the $10.3 billion Long Range Transmission Planning mission that entails 18 tasks working all through the MISO Midwestern area.
“Those are, unfortunately, more the exception than the rule, but they are good examples of what we need to do everywhere,” Gramlich advised CNBC.

In Minnesota, the nonprofit electrical energy cooperative Great River Energy is charged with ensuring 1.3 million individuals have dependable entry to vitality now and sooner or later, in response to vice chairman and chief transmission officer Priti Patel.
“We know that there’s an energy transition happening in Minnesota,” Patel advised CNBC. In the final 5 years, two of the area’s largest coal crops have been offered or retired and the area is getting extra of its vitality from wind than ever earlier than, Patel stated.
Great River Energy serves a few of the poorest counties within the state, so protecting vitality prices low is a main goal.
“For our members, their north star is reliability and affordability,” Patel advised CNBC.
An consultant of the Northland Reliability Project, which Minnesota Power and Great River Energy are working collectively to construct, is talking with group members at an open home concerning the mission and why it’s important.
transmission strains, vitality grid, clear vitality
Great River Energy and Minnesota Power are within the early levels of constructing a 150-mile, 345 kilovolt transmission line from northern to central Minnesota. It’s known as the Northland Reliability Project and can price an estimated $970 million.
It’s one of many segments of the $10.3 billion funding that MISO authorized in July, all of that are slated to be in service earlier than 2030. Getting to that plan concerned greater than 200 conferences, in response to MISO.
The advantage of the mission is predicted to yield a minimum of 2.6 and as a lot as 3.8 instances the mission prices, or a delivered worth between $23 billion and $52 billion. Those advantages are calculated over a 20-to-40-year time interval and keep in mind numerous development inputs together with prevented capital price allocations, gasoline financial savings, decarbonization and threat discount.
The price will finally be borne by vitality customers residing within the MISO Midwest subregion primarily based on utilization utility’s retail charge association with their respective state regulator. MISO estimates that buyers in its footprint can pay a median of simply over $2 per megawatt hour of vitality delivered for 20 years.
But there may be nonetheless a protracted course of forward. Once a mission is authorized by the regional planning authority — on this case MISO — and the 2 endpoints for the transmission mission are determined, then Great River Energy is answerable for acquiring all the land use permits needed to construct the road.
“MISO is not going to be able to know for certain what Minnesota communities are going to want or not want,” Patel advised CNBC. “And that gives the electric cooperative the opportunity to have some flexibility in the route between those two endpoints.”
For Great River Energy, a vital element of partaking with the area people is internet hosting open homes the place members of the general public who reside alongside the proposed route meet with mission leaders to ask questions.
For this mission, Great River Energy particularly deliberate the route of the transmission to run alongside a beforehand current corridors as a lot as attainable to attenuate landowner disputes. But it is at all times a fragile topic.

“Going through communities with transmission, landowner property is something that is very sensitive,” Patel advised CNBC. “We want to make sure we understand what the challenges may be, and that we have direct one-on-one communications so that we can avert any problems in the future.”
At instances, landowners give an absolute “no.” In others, cash talks: the Great River Energy cooperative will pay a landowner whose property the road goes by a one-time “easement payment,” which can differ primarily based on the land concerned.
“A lot of times, we’re able to successfully — at least in the past — successfully get through landowner property,” Patel stated. And that is because of the work of the Great River Energy workers within the allowing, siting and land rights division.
“We have individuals that are very familiar with our service territory, with our communities, with local governmental units, and state governmental units and agencies and work collaboratively to solve problems when we have to site our infrastructure.”
Engaging with all members of the group is a needed a part of any profitable transmission line build-out, Patel and Johnson confused.
At the tip of January, MISO held a three-hour workshop to kick off the planning for its subsequent tranche of transmission investments.
“There were 377 people in the workshop for the better part of three hours,” MISO’s Johnson advised CNBC. Environmental teams, trade teams, and authorities representatives from all ranges confirmed up and MISO vitality planners labored to attempt to steadiness competing calls for.
“And it’s our challenge to hear all of their voices, and to ultimately try to figure out how to make it all come together,” Johnson stated.
