Grid Services funding program

The Solar and Wind Grid Services and Reliability Demonstration funding program aims to demonstrate the reliable operation of power systems that have up to 100% of their power contribution coming from solar, wind, and battery storage resources.

The U.S. Department of Energy (DOE) Solar Energy Technologies Office (SETO) and Wind Energy Technologies Office (WETO) announced the Grid Services funding opportunity on August 2, 2022 and the eight selected projects on May 10, 2023.


Grid services largely involve electric generators maintaining stable grid voltages and frequencies and are critical to maintain the reliability and resilience of the electric power grid. Because new wind and solar generation are interfaced with the grid through power electronic inverters, they have different characteristics and dynamics than traditional sources of generation that currently supply these services. The projects in this funding program support the development of controls and methods to demonstrate that a grid fully powered by inverter-based resources (IBRs) can reliably operate with services provided by wind and solar generation.


These projects will help increase the reliability of energy systems as more solar and wind energy are added to the grid, which will help achieve a decarbonized electricity sector by 2035.

Location: Knoxville, TN
DOE Award Amount: $3.4 million
Awardee Cost Share: $3.4 million
Principal Investigator: Erik Ela
Project Description: This project is developing a multi-level control architecture for power systems that supports ancillary services to the grid, including active and reactive power event and non-event reserve services. The team aims to demonstrate the capability of these technologies to provide a collection of bulk system ancillary services reliably and over a period longer than what has been demonstrated in the past, which will instill confidence in the new technology from system operators. Additionally, the new architecture will be able to offer these grid services more cost effectively and will improve how often these services would be available to the grid.

GE Renewable Energy

Project Name: GRID-READY WIND: Reliable and Economical Grid Services Design, Implementation and Demonstration at the Great Pathfinder Wind Power Plant
Location: Schenectady, NY
DOE Award Amount: $3.5 million
Awardee Cost Share: $3.5 million
Principal Investigator: Rojan Bhattarai
Project Description: This project aims to design, implement, and demonstrate reliable and economical grid services with grid-following and grid-forming IBRs. The work is primarily taking place at the Great Pathfinder wind power plant in Iowa. The project includes a commercial-scale demonstration of grid services using emerging grid-forming technology in Type-III wind turbines with electricity output controlled by converters. This demonstration will encourage confidence in service operators to consider wind power plants as a more flexible stand-alone resource that can provide grid services over extended periods of time. This has the potential to spur further adoption of IBRs and ensure the United States meets its 2035 net-zero power sector goals. This project is jointly funded by WETO and SETO.

Portland General Electric Company

Project Name: Demonstration of Grid Services by a 300-MW Wind, Solar and Battery Storage Combined Power Plant with Mixed Grid-Forming and Grid-Following Technologies
Location: Portland, OR
DOE Award Amount: $4.5 million
Awardee Cost Share: $4.5 million
Principal Investigator: Song Wang
Project Description: This project aims to demonstrate grid services using mixed grid-forming and grid-following technologies at the Wheatridge Renewable Energy Facility in Oregon, North America's first energy center to combine wind, solar, and energy storage systems in one location. The project team will establish a two-way communication channel between grid engineers and inverter vendors so they can collaborate to better understand the effects of grid-forming IBRs on the grid and provide feedback to inverter vendors of the real needs of the power grid. If successful, this will be the first bulk power system-connected grid-forming inverter-based power plant in the United States. The success of this project will greatly encourage utilities to consider including grid-forming capabilities in their own interconnection requirements.
