This story is a part of CNBC’s “Transmission Troubles” sequence, an inside have a look at why the getting 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 preventing local weather change.
Wind and solar energy turbines wait in yearslong bureaucratic strains to hook up with the facility grid, solely to be confronted with charges they cannot afford, forcing them to scramble for extra money or pull out of tasks fully.
This software course of, referred to as the interconnection queue, is delaying the distribution of fresh energy and hampering the U.S. in reaching its local weather objectives.
The interconnection queue backlog is a symptom of a bigger local weather drawback for the US: There usually are not sufficient transmission strains to help the transition from a fossil fuel-based electrical system to a decarbonized power grid.
Shock payment will increase
The Oceti Sakowin Energy Authority, a nonprofit governmental entity owned by seven Sioux Indian tribes, is working to construct 570 megawatts of wind energy era to promote to prospects in South Dakota.
“Financial growth by renewable power speaks to the very coronary heart of Lakota tradition and values – being accountable stewards of Grandmother Earth, Unci Maka,” Jonathan E. Canis, normal counsel for the Oceti Sakowin Energy Authority, informed CNBC. “Collectively our tribes occupy virtually 20% of the land space of South Dakota. And the consultants who’ve been measuring our wind sources actually describe them as ‘screamin.’.”
To attach wind energy era to the electrical grid and generate profits from the sale of that energy, the Oceti Sakowin Energy Authority — like each electrical energy generator within the U.S. — has to submit an software referred to as an interconnection request to whichever group is overseeing the coordination of the electrical grid in that area. Generally it is a regional transmission planning authority, different occasions a utility.

The Oceti Sakowin Energy Authority desires to construct two wind energy tasks and the Ta’teh Topah venture, deliberate to be 450 megawatts, is the bigger of two wind tasks. The transmission tie-line for the Ta’teh Topah venture will cross the rangeland and the river to interconnect with a Basin Electrical transmission line east of the Missouri River.

In late 2017, the Oceti Sakowin Energy Authority paid a $2.5 million deposit to safe a spot in line for its software to be reviewed by the Southwest Energy Pool, a regional grid operator.
5 years later, in 2022, the Southwest Energy Pool got here again and informed it that the payment to hook up with the grid would really be $48 million. That is as a result of connecting all that new energy to the grid would require main updates to the transmission infrastructure.
The Oceti Sakowin Energy Authority had 15 enterprise days to provide you with the additional $45.5 million.
“Evidently, we could not do it and needed to drop out,” Canis informed CNBC.
Now, the Oceti Sakowin Energy Authority is reevaluating the dimensions and composition of the venture and plans to reenter the interconnection queue by the tip of the 12 months. That might imply one other yearslong wait in line.
These burdens are typical.
In 2020, Pine Gate Renewables had a photo voltaic venture situated within the Piedmont area of North Carolina that it anticipated to value $5 million to hook up with the electrical grid. The native utility answerable for overseeing the interconnection course of informed Pine Gate it could be greater than $30 million. Pine Gate needed to terminate the venture as a result of it could not afford the brand new charges, its vp of regulatory affairs, Brett White, informed CNBC.
“We view, as an organization, the interconnection drawback as the most important obstacle to the trade proper now and the prices related to interconnection are the most important motive {that a} venture dies on the vine,” White mentioned. “It is the most important wild card you might have going into the venture growth cycle.”
There are efforts underway to enhance the effectivity of the method, however they’re basically placing a Band-Help on prime of a fair deeper drawback in the US: There is not sufficient transmission infrastructure to help the power transition from fossil gas sources of power to wash sources of power.
“You can make the method for the queue as environment friendly and pristine as attainable and it nonetheless couldn’t be all that efficient as a result of sooner or later you are going to run out of transmission headroom,” Wooden Mackenzie analyst Ryan Sweezey informed CNBC.

Ready in line
The complete electrical grid within the U.S. has put in capability of 1,250 gigawatts. There are at the moment 2,020 gigawatts of capability within the interconnection queue strains across the nation, in accordance with a report printed Thursday by the Lawrence Berkeley Nationwide Laboratory. That features 1,350 gigawatts of energy capability, principally clear, trying to be constructed and linked to the grid. The remainder, 670 gigawatts, is for storage.
In 2022, the lively power capability in interconnection queues within the U.S. is about 2,020 gigawatts and exceeds the put in capability of whole U.S. energy plant fleet, which is about 1,250 gigawatts, in accordance with the report on interconnection queues out of Lawrence Berkeley Nationwide Laboratory printed Thursday.

Berkeley Lab pulls interconnection queue knowledge from the entire regional planning territories in the US and from between 35 and 40 utilities that aren’t lined by areas with regional planning authorities. The info covers between 85% and 90% of the electrical energy load in the US, Joseph Rand, an power coverage researcher and the lead writer of the research, informed CNBC.
The interconnection course of begins with a request to hook up with the grid, which formally enters the facility generator within the interconnection queue. The following step is a sequence of research — the feasibility, system and amenities research — the place the grid operator determines what gear or upgrades can be essential to get the brand new energy era on the grid and what it’s going to value.
If all of the events can agree, then the facility generator and grid operator attain an interconnection settlement, which establishes the grid enhancements the facility generator can pay for.
The overall energy capability that comes out from a fossil fuel-burning energy plant is usually a lot better than the capability from renewable vegetation. Which means it may possibly take a number of wind or solar energy era vegetation — and, due to this fact, interconnection requests — to get the identical items of power on-line.
A single pure fuel plant might be 1,200 megawatts, Sweezey informed CNBC. “That is one request — 1,200 megawatts,” Sweezey mentioned. “Whereas normally if you are going to get that very same quantity of capability with renewables, that is going to be six, seven, eight, 9, 10 completely different tasks. In order that’s 10 completely different requests within the queue.”
On common, it took a brand new energy era venture 35 months to go from the interconnection request being filed with a grid operator to an interconnection settlement being reached in 2022, in accordance with Berkeley Lab.

How did this course of turn out to be such an issue?
The U.S. power grid is a patchwork system of many regional utility firms. Some present transmission companies and a few do not.
In an effort to advertise competitors, the Federal Vitality Regulatory Fee issued an order in 1996 saying transmission service needs to be offered to energy turbines on a nondiscriminatory foundation. This allowed every kind of energy turbines, together with these that don’t personal transmission infrastructure, to compete. In 2003, it issued one other order that standardized the interconnection course of for power turbines.
Each orders “tried to make the companies one wants nondiscriminatory and honest to all customers, for his or her respective service,” in accordance with Rob Gramlich, founding father of transmission market intelligence agency Grid Methods.

That course of labored properly sufficient when the facility era trade was constructing massive, centrally situated power vegetation that burned fossil fuels. However the course of began to point out indicators of pressure round 2008 when renewable power began to come back on-line in locations the place there was not enough transmission, Gramlich informed CNBC. In April 2008, MISO, one of many regional operators, mentioned it could take 42 years, till 2050, for it to get by its interconnection queue.
Reforms in 2008 and 2012 helped somewhat bit, Gramlich informed CNBC. “However I believe everyone’s realizing now that that unique course of is basically unsuited to the brand new era combine.”
The interconnection course of is particularly unhealthy at estimating battery storage, mentioned White. That is as a result of transmission planning is at all times defaulting to the worst-case state of affairs, however batteries will draw power from the grid when the demand is low and power costs are low, after which use that saved energy when the grid is at or close to capability. Utilizing worst-case-scenario planning for battery storage basically misses the purpose of a battery.
“The upgrades which might be going to be triggered on the system are going to be very, very intensive and really, very costly. And they also hand you a invoice that displays that,” White informed CNBC.
However that sort of system improve “in our thoughts is completely disassociated from the economics of the asset, and not likely wanting on the profit that the venture goes to supply to the system,” White mentioned.
Texas makes it simpler
The charges of interconnection functions that truly attain business completion fluctuate considerably, however none are greater than 38% within the New England area, in accordance with Berkeley Lab. The Texas grid operator, Electrical Reliability Council of Texas, or ERCOT, has a completion charge of 31% and is the one different area with a completion charge of over 30%.
On the low finish, the California Unbiased System Operator area has an 13% completion charge and the New York Unbiased System Operator area is at 15%.

The low proportion of interconnection requests that truly get constructed is partly due to the excessive value to attach.
Within the MISO area, as an illustration, interconnection prices had been typically lower than $100 per kilowatt-hour from 2008 to 2016, however have risen to some hundred {dollars} per kWh for wind and photo voltaic, with spikes as excessive as $1,000 per kWh in some elements of the area, Gramlich informed CNBC.
Including even small quantities of power to the grid requires infrastructure enhancements as a result of it is almost at capability. Pushing these prices onto the builders of particular person renewable tasks typically makes them economically unsustainable.
“These tasks ended up withdrawing from the queue or terminating, as a result of they do not pencil anymore,” White informed CNBC.
A number of the completion charges are artificially low as a result of builders do not really anticipate to finish all of them, however as a substitute store the identical venture round to numerous regional grid operators to get the perfect deal — what’s referred to as “speculative queuing,” Sweezey informed CNBC. It is not costly to get into queues, so builders submit functions to get details about which location would require the least costly upgrades.
For grid operators, having energy turbines stuff their queues is overwhelming an already taxed system.
“Initiatives which have come by the method usually are not being constructed and turning into operational,” Jeffrey Shields, a PJM Interconnection spokesperson, informed CNBC. “There are about 38,000 MW of renewable tasks that haven’t any additional PJM necessities however usually are not being constructed due to siting, provide chain, or different points dealing with the trade that aren’t associated to PJM’s interconnection course of.”
The lengthy software timelines and costly upgrades have made Texas a fascinating place to construct renewable power tasks as a result of the state has its personal interconnection software course of.
“There’s Texas, after which there’s the remainder of the nation with respects to interconnection,” White of Pine Gate informed CNBC. Texas would not require the identical degree of community upgrades to get energy era linked to the grid so getting a venture on-line in Texas is quicker and decrease value than the remainder of the nation, White mentioned.
“You may put a venture within the PJM queue tomorrow and it might not get constructed and constructed till 2030, whereas for those who do the identical with the Texas venture, proper now, it is in all probability on-line in two to a few years. So it is only a a lot, a lot shorter timeline to business operation for a venture in Texas,” White informed CNBC.
However Texas additionally has a novel danger as a result of ERCOT can determine to restrict the quantity of energy {that a} generator can promote to the market if a selected electrical hall will get overly congested.
“It is a bit of a double-edged sword,” White informed CNBC. However with infrastructure offers, “time kills offers, time kills tasks,” White mentioned, so power builders might desire to take the danger and get the deal finished.

How does this example get mounted?
In June 2022, FERC issued a proposal on interconnection reforms to handle queue backlogs and has since acquired a slew of public feedback.
“We perceive that 80 to 85 % of the tasks which might be ready within the queue finally usually are not being constructed. I believe FERC has a chance right here to guarantee that we unlock that bottleneck and that we do all that we will to maneuver these tasks ahead,” FERC Chairman Willie Phillips mentioned on March 16, in accordance with an announcement offered by a FERC spokesperson.
The proposed rule change would provide incremental enhancements, like offering info to builders to allow them to make extra knowledgeable siting selections with out flooding the queue with speculative requests, and imposing extra strict mandates on the regional grid operators to finish research in a given time interval, Rand of Berkeley Lab informed CNBC.
“I do suppose what FERC is proposing has the potential to enhance this example,” Rand informed CNBC. However basically, these iterative modifications will not be a silver bullet.
“The power transition is right here. However our updating and enlargement of our electrical transmission system up to now has not even remotely stored tempo with that velocity, charge of change we’re seeing on the generator-supply facet,” mentioned Rand.
There’s additionally a scarcity of the varieties {of electrical} and transmission engineers required to course of all of those functions, Sweezey and White informed CNBC. “There’s simply not sufficient individuals and so we’ve to consider what’s the smartest method to maximize that experience. And which means getting these engineers out of among the rote guide knowledge entry and into the precise evaluation,” White informed CNBC.
Another choice is constructing new sources of fresh power that may be constructed nearer to the place demand is required, like small nuclear reactors, Sweezey informed CNBC. “I simply do not suppose individuals have come to that realization but.”
Constructing enough transmission to help the power transition isn’t essentially a technical problem as a lot as it’s a political one.
“The kind of coordination and planning that is required for this sort of large-scale transmission — this includes perhaps a number of utilities, a number of grid operators, a number of states, cities, counties, every little thing, even the feds are all concerned — and that’s antithetical to the U.S. as structured as a decentralized nation,” Sweezey informed CNBC.
However the stakes are excessive.
“Even with the entire work, with all this nice stuff that is within the IRA and the entire wind that’s within the sails of decarbonization within the renewable trade, if you cannot tackle transmission and infrastructure, then these objectives aren’t going to be met,” White informed CNBC.
“It truly is the bottleneck that is stopping that from occurring.”
