The U.S. Department of Energy (DOE) Interconnection Innovation e-Xchange (i2X) Program is looking to fund experts in bulk electric power system modeling and innovative transmission techniques to provide services to transmission providers (Voucher Recipients) through the Interconnection Cost Reduction Solutions for Transmission Grid (iCRS-T) Voucher Program. This Voucher Program will help address the National Energy Emergency by supporting innovations to streamline and expedite interconnection services by implementing cutting-edge technology solutions, such as grid-enhancing technologies, flexible interconnection, and many other innovations.
The iCRS-T Voucher Program will increase Voucher Recipient understanding and implementation of advanced interconnection topics, with the goal of reducing transmission interconnection costs. Industry experts (Voucher Providers) will assist transmission providers in modeling power electronics in large data center loads, power electronics in inverter-based resources, controls for the flexible operation of data center loads, storage, generation resources, and hybrid facilities, and advanced transmission technologies that are currently underutilized. These new modeling capabilities can give transmission providers more cost-saving options and either reduce the need for costly network upgrades or provide a faster path for interconnection alongside more extensive transmission upgrades. Additionally, Voucher Providers will train transmission providers in modeling innovative transmission technologies and controls, including incorporating these into electromagnetic transient (EMT) studies.
This Opportunity will open for Voucher Provider applications on February 19, 2026, and applications will be accepted until April 2, 2026. This Opportunity is anticipated to open for Voucher Recipient applications in Spring 2026, with matching of Providers and Recipients completed in Summer 2026. DOE reserves the right to request additional information about applications prior to selection, if necessary. To receive reminders about this and future opportunities, sign up to Join Our Ecosystem.

Available Funding
DOE will fund 16 to 30 Voucher Provider/Recipient matches with projects expected to last up to two years. The value of each Voucher will depend on the service requested, with the estimated value of support services per Recipient ranging from $50,000 to $250,000.
The iCRS-T program supports innovative strategies to increase affordable and reliable interconnection of new loads and energy generation resources by linking transmission providers with technology experts and training. This will increase transmission providers’ understanding and application of advanced transmission interconnection techniques, empowering them to implement cost reduction solutions. By optimizing existing grid resources and embracing novel ways to manage electricity use, transmission providers can unlock existing capacity and add new resources needed to meet data center-driven load growth while lowering costs for all Americans.
Expected maximum Voucher value will be up to $250,000 of work (actual values vary depending on the details of the Provider’s capability statement). Vouchers will be distributed as in-kind support, meaning that ENERGYWERX will directly reimburse the Voucher Provider for the work they have completed on behalf of the Voucher Recipients.
The first submission window solicits capability statements from potential Voucher Providers. After Voucher Provider selection, a second submission window will be opened to solicit requests from potential Voucher Recipients. Pending availability of funds, additional submission windows may open in the future.
As part of the application form, potential Providers will submit the details of their capability statement, including the technical scope, deliverables, price, and throughput of the capability. Each Voucher Provider may submit up to seven unique capabilities per Voucher Opportunity. The unique capabilities can be the same grouped services at tiered service levels. The application form must be submitted once per capability and service tier, no more than seven separate times. Additional submissions will not be reviewed.
Only work related to providing services that will result in interconnection cost reductions will be eligible to receive a Voucher under this Opportunity. Eligible services include:
A unique capability can offer the same set of services as another capability at different service levels or tiers, to best represent the range of potential Voucher Recipient needs for the service. Service levels can be based on existing expertise, size of system to be modeled, urgency of need, or other differentiating factors. Each service level must be submitted as a separate application within the seven-capability limit.
If selected, Voucher Providers will be required to complete the following four milestones for each Recipient match:
The Voucher Provider is responsible for timely submission of all milestones to the ENERGYWERX point of contact, but Provider and Recipient are expected to work collaboratively on project milestones.
The schedule of milestone due dates will depend on the project and will be established in the relevant agreement between ENERGYWERX and the Voucher Provider. Milestones 1 and 2 must be completed before modeling activities can begin. Milestone 3 should be completed approximately 50-75% through the project timeline. Milestone 4 should be submitted upon project completion.
Participating in the Informational Webinars will improve your knowledge in the expectations of the opportunity and application.
