AUSTIN, Texas (May 6, 2025) — Enverus, the most trusted energy-dedicated SaaS company that leverages generative AI across its solutions, is releasing its 2025 Interconnection Queue Outlook, a comprehensive collection of power generation and transmission projects that show requests to connect to the U.S. power grid. Leveraging its proprietary machine learning model, Enverus assigns a probability of success to every queued power plant project, enabling the analysis of trends and insights into portfolio valuation and queue dynamics. With interconnection queue challenges posing a major hurdle for projects, this outlook offers a data-driven perspective and provides critical insights for developers, investors and policymakers navigating the evolving energy landscape.
Enverus experts continue to underscore that generous tax credits from the Inflation Reduction Act and the EPA’s update to 40 CFR Part 60, which mandates additional coal retirements, have significantly boosted demand for renewable energy projects across the United States. The surge in investment and development has overwhelmed interconnection queues, with a record number of projects seeking grid connections. This has exceeded grid operators’ processing capacity, causing significant delays and project suspensions. Understanding project suspensions and success rates is critical, as these factors vary by independent system operators (ISO), technology type and project stage.
In a recent Enverus Intelligence® Research (EIR) report, analysts found about 90% of renewable generation projects do not progress beyond the interconnection queue, and that the New York ISO (NYISO), Southwest Power Pool (SPP), Pennsylvania-New Jersey-Maryland (PJM) and ISO New England (ISO-NE) have higher suspension rates later in the project lifecycle, with Interconnection Agreement suspension rates ranging from 46% to 79%, compared to around 20% in Electric Reliability Council of Texas (ERCOT), California Independent System Operator (CAISO) and Midcontinent Independent System Operator (MISO). Projects in these markets show minimal improvement in completion probability until reaching construction. Understanding these regional differences helps developers maximize investment potential by minimizing project delays and increasing the odds of making it through the queue.
Enverus customers continue to tout the benefits of projects and services like the Interconnection Queue. “Congestion, competition, aging infrastructure and interconnection bottlenecks are the biggest obstacles in the way of reaching our goal of siting projects, maximizing the production of renewable energy generators and delivering power where it’s needed the most,” says Silvia Alborghetti, director of Business Development at zhero. “But the information we need for project siting requires lots of resources and time to gather.”
With low project success rates, power developers need better data to navigate risks and opportunities in this evolving landscape, and that’s where Enverus’ unique Interconnection Queue shines. Enverus provides a comprehensive view of key variables, including asset economics, power demand growth, existing and planned transmission lines, and substation-level available transfer capability to name a few.
Enverus’ recent acquisition of Pearl Street Technologies brings additional capabilities to customers’ interconnection toolkits. Through Interconnect®, users can generate injection capacity maps, run shadow studies, evaluate cost allocation scenarios and assess interconnection risks, all in house and in hours, to guide decision-making and steer more projects to interconnection success.
“Quick analysis is a competitive advantage, especially when we receive proposals from different sources of land originators who aren’t going to wait long on our decision,” says Andrea Braccialarghe, president and CEO of zhero. “Enverus provides the diverse data in one place we need for quantitative and qualitative analysis for our leadership team to make a decision about investing in specific areas,” she said.
Key challenges identified in the 2025 Interconnection Queue:
- Compounding delays across several stages were the main driver of CAISO’s higher-than-average project development timelines, which averaged close to eight years for all project types. ISONE had the shortest development timeline, averaging nearly 3.6 years to reach operation, followed closely by ERCOT at about 4.2 years.
- NYISO, SPP, PJM and ISONE have more suspensions later in the project lifecycle, with Interconnection Agreement suspension rates ranging from 46% to 79%, compared to around 20% in ERCOT, CAISO and MISO. Consequently, projects in these markets show minimal improvement in completion probability until reaching construction.
- Only a fraction of capacity in the interconnection queues are expected to reach operation. Based on Enverus’ gradient-boosting machine learning model, only ~10% of projects will successfully come online in the next three years.
