Enhancing US Power Grid by using AI to Accelerate Permitting
The increased demand for power in the United States is driven by new technologies such as artificial intelligence, data analytics, and other computationally intensive activities that utilize ever faster and power-hungry processors. The federal government’s desire to reshore critical manufacturing industries and shift the economy from service to goods production will, if successful, drive energy demands even higher.
Many of the projects that would deliver the energy to meet rising demand are in the interconnection queue, waiting to be built. There is more power in the queue than on the grid today. The average wait time in the interconnection queue is five years and growing, primarily due to permitting timelines. In addition, many projects are cancelled due to the prohibitive cost of interconnection.
We have identified six opportunities where Artificial Intelligence (AI) has the potential to speed the permitting process.
- AI can be used to speed decision-making by regulators through rapidly analyzing environmental regulations and past decisions.
- AI can be used to identify generation sites that are more likely to receive permits.
- AI can be used to create a database of state and federal regulations to bring all requirements in one place.
- AI can be used in conjunction with the database of state regulations to automate the application process and create visibility of permit status for stakeholders.
- AI can be used to automate and accelerate interconnection studies.
- AI can be used to develop a set of model regulations for local jurisdictions to adapt and adopt.
Challenge and Opportunity
There are currently over 11,000 power generation and consumption projects in the interconnection queue, waiting to connect to the United States power grid. As a result, on average, projects must wait five years for approval, up from three years in 2010.
Historically, a large percentage of projects in the queue, averaging approximately 70%, have been withdrawn due to a variety of factors, including economic viability and permitting challenges. About one-third of wind and solar applications submitted from 2019 to 2024 were cancelled, and about half of these applications faced delays of 6 months or more. For example, the Calico Solar Project in the California Mojave Desert, with a capacity of 850 megawatts, was cancelled due to lengthy multi-year permitting and re-approvals for design changes. Increasing queue wait time is likely to increase the number of projects cancelled and delay those that are viable.
The U.S. grid added 20.2 gigawatts of utility-scale generating capacity in the first half of 2024, a 21% increase over the first half of 2023. However, this is still less power than is likely to be needed to meet increasing power demands in the U.S. Nor does it account for the retirement of generation capacity, which was 5.1 gigawatts in the first half of 2024. In addition to replacing aging energy infrastructure as it is taken offline, this new power is critically needed to address rising energy demands in the U.S. Data centers alone are increasing power usage dramatically, from 1.9% of U.S. energy consumption in 2018 to 4.4% in 2023, and with an expected consumption of at least 6.7% in 2028.
If we want to achieve the Administration’s vision of restoring U.S. domestic manufacturing capacity, a great deal of generation capacity not currently forecast will also need to be added to the grid very rapidly, far faster than indicated by the current pace of interconnections. The primary challenge that slows most power from getting onto the grid is permitting. A secondary challenge that frequently causes projects to be delayed or cancelled is interconnection costs.
Projects frequently face significant permitting challenges. Projects not only need to obtain permits to operate the generation site but must also obtain permits to move power to the point where it connects to the existing grid. Geographically remote projects may require new transmission lines that cover many miles and cross multiple jurisdictions. Even projects relatively close to the existing grid may require multiple permits to connect to the grid.
In addition, poor site selection has resulted in the cancellation of several high-profile renewable installation projects. The Battle Born Solar Project, valued at $1 billion with a 850 megawatt capacity, was cancelled after community concern that the solar farm would impact tourism and archaeological sites in the Mormon Mesa in Nevada. Another project, a 150 megawatt solar facility proposed for Culpeper County, Virginia, was denied permits for interfering with the historic site of a Civil War battle. Similarly, a geothermal plant in Nevada had to be scaled back to less than a third of its original plan after it was found to be in the only known habitat of the endangered Dixie Valley toad. While community outrage over renewable energy installations is not always avoidable, mostly due to complaints about construction impacts and misinformation, better site selection could save developers time and money by avoiding locations that encroach on historical sites, local attractions, or endangered species‘ habitats.
Projects have also historically faced cost challenges as utilities and grid operators could charge the full cost of new operating capacity to each project, even when several pending projects could utilize the same new operating assets. On July 28, 2023, FERC issued a final rule with a compliance date of March 21, 2024, that requires transmission providers to consider all projects in the queue and determine how operating assets would be shared when calculating the cost of connecting a project to the grid. However, the process for calculating costs can be cumbersome when many projects are involved.
On April 15th, 2025, the Trump Administration issued a Presidential Memorandum titled “Updating Permitting Technology for the 21st Century.” This memo directs executive departments and agencies to take full advantage of technology for environmental review and permitting processes and creates a permitting innovation center. While it is unclear how much authority the PIC will have, it demonstrates the Administration’s focus in this area and may serve as a change agent in the future. There is an opportunity to use AI to improve both the speed and the cost of connecting new projects to the grid. Below are recommendations to capitalize on this opportunity.
Plan of Action
Recommendation 1. Funding for PNNL to expand the PolicyAI NEPA model to streamline environmental permitting processes beyond the federal level.
In 2023, Pacific Northwest National Laboratory (PNNL) was tasked by DOE with developing a PermitAI prototype to help regulators understand the National Environmental Policy Act (NEPA) regulations and speed up project environmental reviews. PNNL data scientists created an AI-searchable database of federal impact environmental statements, composed primarily of information that was not readily available to regulators before. The database contains textual data extracted from documents across 2,917 different projects stored as 3.6 million tokens from the GPT-2 tokenizer. Tokens are the units in which text is broken down for natural language processing AI models. The entire dataset is currently publicly available via HuggingFace. The database is then used for generative-AI searching that can quickly find documents and summarize relevant results as a Large Language Model (LLM). While the development of this database is still preliminary and efficiency metrics have not yet been published, based on complaints from those involved in permitting about the complexity of the process and the lack of guidelines, this approach should be a model for tools that could be developed and provided to state and local regulators to assist with permitting reviews.
In 2021, PNNL created a similar process, without using AI, for NEPA permitting for small-to medium-sized nuclear reactors, which simplified the process and reduced the environmental review time from three to six years to between six and twenty-four months. Using AI has the potential to reduce the process exponentially for renewables permitting. The National Renewable Energy Laboratory (NREL) has also studied using LLMs to expedite the processing of policy data from legal documents and found the results to support the expansion of LLMs for policy database analysis, primarily when compared to the current use of manual effort.
State and local jurisdictions can use the “Updating Permitting Technology” Presidential Memorandum as guidance to support the intersection between state and local permitting efforts. The PNNL database of federal NEPA materials, trained on past NEPA cases, would be provided by PNNL to state jurisdictions as a service, through a process similar to that used by EPA to ensure that state jurisdictions do not need to independently develop data collection solutions. Ideally, the initial data analysis model would be trained to be specific to each participating state and continually updated with new material to create a seamless regulatory experience.
Since PNNL has already built a NEPA model and this work is being expanded to a multi-lab effort that includes NREL, Argonne and others The House Energy and Water development committee could appropriate additional funding to the Office of Policy (OP) or EERE (Energy Efficiency and Renewable Energy) to enable the labs to expand the model and make it available to state and local regulatory agencies to integrate it into their permitting processes. States could develop models specific to their ordinances with the backbone of PNNL’s PermitAI. This effort could be expedited through engagement with the Environmental Council of the States (ECOS).
A shared database of NEPA information would reduce time spent reviewing backlogs of data from environmental review documents. State and local jurisdictions would more efficiently identify relevant information and precedent, and speed decision-making while reducing costs. An LLM tool also has the benefit of answering specific questions asked by the user. An example would be answering a question about issues that have arisen for similar projects in the same area.
Recommendation 2. Appropriate funding to expand AI site selection tools and support state and local pilots to improve permitting outcomes and reduce project cancellations.
AI could be used to identify sites that are suitable for energy generation, with different models eventually trained for utility-scale solar siting, onshore and offshore wind siting, and geothermal power plant siting. Key concerns affecting the permitting process include the loss of arable land, impacts on wildlife, and community responses, like opposition based on land use disagreements. Better site selection identifies these issues before they appear during the permitting process.
AI can access data from a range of sources, including satellite imagery from Google Earth, commercially available lidar studies, and local media screening to identify locations with the least number of potential barriers or identify and mitigate barriers for sites that have been selected. Unlike action one, which involves answering questions by pulling from large databases using LLMs, this would primarily utilize machine learning algorithms that process past and current data to identify patterns and predict outcomes, like energy generation potential. Examples of datasets these tools can use are the free, publicly available products created by the Innovative Data Energy Applications (IDEA) group in NREL’s Strategic Energy Analysis Center (SEAC), including the national solar radiation database and the wind resource database. The national solar radiation database visualizes the amount of solar energy potential at a given time and predicts future availability of solar energy for a given location in the dataset, which covers the entirety of the United States.
The wind resource database is a collection of modeled wind resource estimates for locations within the United States. In addition, Argonne National Lab has developed the GEM tool to support the NEPA reviews for transmission projects. A few start-ups have synthesized a variety of datasets like these and created their databases for information like terrain and slope to create site-selection decision-making tools. AI analysis of local news and landmarks important to local communities to identify locations that are likely to oppose renewable installations is particularly important since community opposition is often what kills renewable generation projects that have made it into the permitting process.
The House Committee for Energy and Water Development could appropriate funds to DOE’s Grid Deployment Office which could collaborate with EERE, FECM (Fossil Energy and Carbon Management), NE (Nuclear Energy) and OE (Office of Electricity) to further expand the technology specific models as well as to expand Argonne’s GEM tool. GDO could also provide grant funding to state and local government permitting authorities to pilot AI-powered site selection tools created by start-ups or other organizations. Local jurisdictions, in turn, could encourage use by developers.
Better site selection would speed permitting processes and reduce the number of cancelled projects, as well as wasted time and money by developers.
Recommendation 3. Funding for DOE labs to develop an AI-based permitting database, starting with a state-level pilot, to streamline permit site identification and application for large-scale energy projects.
Use AI to identify all of the non-environmental federal, state, and local permits required for generation projects. A pilot project, focused on one generation type, such as solar, should be launched in a state that is positioned for central coordination. New York may be the best candidate, as the Office of Renewable Energy Siting and Electric Transmission has exclusive jurisdiction over on-shore renewable energy projects of at least 25 megawatts.
A second option could be Illinois, which has statewide standards for utility-scale solar and wind facilities where local governments cannot adopt more restrictive ordinances. This would require the development of a database of regulations and the ability to query that database to provide a detailed list of required permits for each project by jurisdiction, the relevant application process, and forms. The House Energy and Water Development Committee could direct funds to EERE to support PNNL, NREL, Argonne, and other DOE labs to develop this database. Ideally, this tool would be integrated with tools developed by local jurisdictions to automate their individual permitting process.
State-level regulatory coordination would speed the approval of projects contained within a single state, as well as improve coordination between states.
Recommendation 4. Appropriate funds for DOE to develop a state-level AI permitting application to streamline renewable energy permit approvals and improve transparency.
Use AI as a tool to complete the permitting process. While it would be nearly impossible to create a national permitting tool, it would be realistic to create a tool that could be used to manage developers’ permitting processes at the state level.
NREL developed a permitting tool with funding from the DOE Solar Energy Technologies Office (SETO) for residential rooftop solar permitting. The tool, SolarAPP+, automates plan review, permit approval, and project tracking. As of the end of 2023, it had saved more than 33,000 hours of permitting staff time for more than 32,800 projects. However, permitting for rooftop solar is less complex than permitting for utility-scale solar sites or wind farms because of less need for environmental reviews, wildlife endangerment reviews, or community feedback. Using the AI frameworks developed by PNNL mentioned in recommendation one and leveraging the development work completed by NREL could create tools similar to SolarAPP+ for large-scale renewable installations and have similar results in projects approved and time saved. An application that may meet this need is currently under development at NREL.
The House Energy and Water Development Committee should appropriate funds for DOE to create an application through PNNL and NREL that would utilize the NREL SolarAPP+ framework that could be implemented by states to streamline the permitting application process. This would be especially helpful for complex projects that cross multiple jurisdictions. In addition, Congress, through appropriation by the House Energy and Water Development Committee to DOE’s Grid Deployment Office, could establish a grant program to support state and local level implementation of this permitting tool. This tool could include a dashboard to improve permitting transparency, one of the items required by the Presidential Memorandum on Updating Permitting Technology.
Developers are frequently unclear about what permits are required, especially for complex multi-jurisdiction projects. The AI tool would reduce the time a developer spends identifying permits and would support smaller developers who don’t have permitting consultants or prior experience. An integrated electronic permitting solution would reduce the complexity of applying for and approving permits. With a state-wide system, state and local regulators would only need to add their requirements and location-specific requirements and forms into a state-maintained system. Finally, an integrated system with a dashboard could increase status visibility and help resolve issues more quickly. These tools together would allow developers to make realistic budgets and time frames for projects to allocate resources and prioritize projects that have the greatest chance of being approved.
Recommendation 5. Direct FERC to require RTOs to evaluate and possibly implement AI tools to automate interconnection analysis processes.
Use AI tools to reduce the complexity of publishing and analyzing the mandated maps and assigning costs to projects. While FERC has mandated that grid operators consider all projects coming onto the grid when setting interconnection pricing, as well as considering project readiness rather than time in queue for project completion, the requirements are complex to implement.
A number of private sector companies have begun developing tools to model interconnections. Pearl Street has used its model to reproduce a complex and lengthy interconnection cluster study in ten days, and PJM recently announced a collaboration with Google to develop an analysis capability. Given the private sector efforts in this space, the public interest would be best served by FERC requiring RTOs to evaluate and implement, if suitable, an automated tool to speed their analysis process.
Automating parts of interconnection studies would allow developers to quickly understand the real cost of a new generation project, allowing them to quickly evaluate feasibility. It would create more cost certainty for projects and would also help identify locations where planned projects have the potential to reduce interconnection costs, attracting still more projects to share new interconnections. Conversely, the capability would also quickly identify when new projects in an area would exceed expected grid capacity and increase the costs for all projects. Ultimately, the automation would lead to more capacity on the grid faster and at a lower cost as developers optimize their investments.
Recommendation 6. Provide funding to DOE to extend the use of NREL’s AI-compiled permitting data to develop and model local regulations. The results could be used to promote standardization through national stakeholder groups.
As noted earlier, one of the biggest challenges in permitting is the complexity of varying and sometimes conflicting local regulations that a project must comply with. Several years ago, NREL, in support of the DOE Office of Policy, spent 1500 staff hours to manually compile what was believed to be a complete list of local energy permitting ordinances across the country. In 2024, NREL used an LLM to compile the same information with a 90% success rate in a fraction of the time.
The House Energy and Water Development Committee should direct DOE to fund the continued development of the NREL permitting database and evaluate that information with an LLM to develop a set of model regulations that could be promoted to encourage standardization. Adoption of those regulations could be encouraged by policymakers and external organizations through engagement with the National Governors Association, the National Association of Counties, the United States Conference of Mayors, and other relevant stakeholders.
Local jurisdictions often adopt regulations based on a limited understanding of best practices and appropriate standards. A set of model regulations would guide local jurisdictions and reduce complexity for developers.
Conclusion
As demand on the electrical grid grows, the need to speed up the availability of new generation capacity on the grid becomes increasingly urgent. The deployment of new generation capacity is slowed by challenges related to site selection, environmental reviews, permitting, and interconnection costs and wait times. While much of the increasing demand for energy in the United States can be attributed to AI, it can also be a powerful tool to help the nation meet that demand.
The six recommendations for AI to speed up the process of bringing new power to the grid that have been identified in this memo address all of those concerns. AI can be used to assist with site selection, analyze environmental regulations, help both regulators and the regulated community understand requirements, develop better regulations, streamline permitting processes, and reduce the time required for interconnection studies.
This memo is part of our AI & Energy Policy Sprint, a policy project to shape U.S. policy at the critical intersection of AI and energy. Read more about the Policy Sprint and check out the other memos here.
The combined generating capacity of the projects awaiting approval is about 1,900 gigawatts, excluding ERCOT and NYISO which do not report this data. In comparison, the generating capacity of the U.S. grid as of Q4 2023 was 1,189 gigawatts. Even if the current high cancellation rate of 70% is maintained, the queue will yield an approximately 50% increase in the amount of power available on the grid through a $600B investment in US energy infrastructure.
FERC’s five-year growth forecast through 2029 predicts an increased demand for 128 gigawatts of power. In that context, the net addition of 15.1 gigawatts of power in the first half of 2024 suggests an increase of 150 gigawatts of power and little excess capacity over the five-year horizon. This forecast is predicated on the assumption that the power added to the grid does not decline, retirements do not increase, and the load forecast does not increase. All these estimates are being applied to a system where supply and demand are already so closely matched that FERC predicted supply shortages in several regions in the summer of 2024.
Construction delays and cost overruns can be an issue, but this is more frequently a factor in large projects such as nuclear and large oil and gas facilities, and is rarely a factor for wind and solar which are factory built and modular.
While the current administration has declared a National Energy Emergency to expedite approvals for energy projects, the order excludes wind, solar, and batteries, which make up 90% of the power presently in the interconnection queue as well as mirroring the mix of capacity recently added to the grid. Therefore, the expedited permitting processes required by the administration only applies to 10% of the queue, composed of 7% natural gas and 3% that includes nuclear, oil, coal, hydrogen, and pumped hydro. Since solar, wind, and batteries are unlikely to be granted similar permitting relief, and relying on as-yet unplanned fossil fuel projects to bring more energy to the grid is not realistic, other methods must be undertaken to speed new power to the grid.
Many of the projects that would deliver the energy to meet rising demand are in the interconnection queue, waiting to be built. AI can improve both the speed and the cost of connecting new projects to the grid.
The decline of the coal industry in the late 20th century led to the dismantling of the economic engine of American coal communities. The AI boom of the 21st century can reinvigorate these areas if harnessed appropriately.
As federal uncertainty grows and climate goals face political headwinds, a new coalition of subnational actors is rising to stabilize markets, accelerate permitting, and finance a more inclusive green economy.
