At the end of May, the U.S. Department of Energy (“DOE”) announced a new program, the Interconnection Innovation e-Xchange (“i2X”), to bring together stakeholders and several of DOE’s National Laboratories[1] to “develop solutions for faster, simpler, and fairer interconnection” of solar, wind, and energy storage resources to the distribution and bulk power grids.[2]
As explained by Secretary of Energy Jennifer Granholm during a “kick-off” webinar held on June 7, the $3,000,000 i2X program is funded by the Infrastructure Investment and Jobs Act passed in November 2021, and is in furtherance of the Biden Administration’s goal of a decarbonized electricity system by 2035.
According to DOE, dramatic expansion of solar and wind energy resources will be needed to meet the Administration’s decarbonization goals, but current interconnection procedures are not designed to accommodate the hundreds of gigawatts of solar, wind, and energy storage resources needed each year, and interconnection queue waiting times for solar, wind, and energy storage projects are increasing.
In April, LBNL issued a study in which it found that, as of the end of 2021, over 1000 GW of generator capacity and 420 GW of storage were seeking interconnection to the bulk power grid.[3] It also found that only 23% of projects that requested interconnection from 2000-2016 have reached commercial operation, with 72% having withdrawn from the interconnection queue. LBNL further found even lower completion rates for wind (20%) and solar (16%) projects during the 2000-2016 period.[4]
The i2X program aims to “address the core issues surrounding grid interconnection,” which DOE identifies as a lack of data, a shortage of human resources and capabilities to manage long interconnection queues, and more complicated grid impact assessments.
During the June 7 kick-off webinar, Secretary Granholm emphasized that DOE will lead the data collection and analysis to ensure that utilities and other stakeholders have the information they need, provide technical assistance to allow groups to test solutions, and create a strategic roadmap.
Although one of the “four key activities” of the i2X program is to create a five-year strategic Interconnection Roadmap to “inform interconnection process improvements,” DOE’s focus on the data collection and analysis and technical aspects of interconnection, and bringing the resources of its National Labs to bear on interconnection reform, perhaps reflect that in general, the processes for transmission level interconnections are regulated by the Federal Energy Regulatory Commission (“FERC”),[5] while the processes for distribution level interconnections are regulated by state public utility commissions.
Under its authority under the Federal Power Act, FERC has established standardized Generator Interconnection Procedures and Standard Interconnection Agreements for Large (over 20 MW) and Small (20 MW and below) generators connecting to the bulk power grid. FERC’s interconnection policies and regulations are implemented by regional transmission organizations (“RTOs”), independent system operators (“ISOs”), and FERC-jurisdictional utilities, including those that are not members of RTOs/ISOs.
The participants thus far in the DOE i2X program include a wide variety of industry participants and stakeholders, including renewable energy developers, utilities, transmission and storage developers, RTOs/ISOs, equipment manufacturers, consulting and law firms and universities, and trade associations. It may be difficult for DOE to forge consensus among such a diverse group, and its five-year horizon will not result in near-term remedies. However, the data collection, analysis and sharing that is a core element of the i2X program potentially could inform pending and anticipated interconnection reforms at the federal and state levels, especially at FERC.
