Smart Grid Investment Grant Program
The Smart Grid Investment Grant (SGIG) program is authorized by the Energy Independence and Security Act of 2007, Section 1306, as amended by the Recovery Act. The purpose of the grant program is to accelerate the modernization of the nation’s electric transmission and distribution systems and promote investments in smart grid technologies, tools, and techniques that increase flexibility, functionality, interoperability, cybersecurity, situational awareness, and operational efficiency. The SGIG projects were selected through a merit-based, competitive solicitation by which successful projects were eligible to receive federal financial assistance for up to 50% of eligible costs. Additional details about the original Funding Opportunity Announcement are available in the SGIG Funding Opportunity Announcement.
There are 99 SGIG projects with a total budget of about $8 billion. The federal share is about $3.4 billion.
SGIG projects were awarded in the following categories described below. Some projects involve equipment and/or software applications that cover two or more topic areas such as AMI and electric distribution systems, customer systems and AMI, or electric transmission systems and electric distribution systems. DOE categorized these projects as integrated or cross cutting.
Customer systems enable smart grid functions in buildings, facilities, and appliances and equipment on the customer side of the meter. These projects primarily involve adding smart grid functions to equipment and/or software applications including “smart” appliances and equipment, home area networks, building or facility energy management systems, distributed energy systems, demand response and load control equipment, energy storage devices, plug-in electric vehicles, and microgrids.
Advanced Metering Infrastructure
Advanced metering infrastructure (AMI) is a system of smart meters, two-way communications networks, and data management systems implemented to enable metering and other information exchange between utilities and their customers.
In addition, a subset of SGIG projects are conducting statistically rigorous studies of consumer behavior and demand response. These projects include applications of AMI, time-based rate programs, and enabling technologies such as Web portals, in-home displays, and programmable communicating thermostats. They also include the use of randomized and controlled experimental designs with treatment and control groups. This effort presents an opportunity to advance the electric power industry’s understanding of consumer behavior through highly rigorous statistical methods.
Electric Distribution Systems
Projects in this topic add smart grid functions to local electric distribution systems in retail electricity markets. Projects primarily involve adding smart grid functions to devices, equipment, and/or software applications including substations, transformer banks, feeder lines, pole-top transformers, and customer interconnection and communications systems. Projects in this area involve distribution automation systems; supervisory control and data acquisition (SCADA) systems; distribution monitoring, control, and optimization systems; load control systems for lowering peak demand; and electric distribution applications of distributed generation and energy storage equipment.
Electric Transmission Systems
Projects in this topic area are aimed at adding smart grid functions to the electric transmission systems in bulk power markets that typically involve power delivery over long distances including multi-state regions. Projects primarily involve adding smart grid functions to devices, equipment, and/or software applications such as phasor measurement units, phasor data concentrators, and visualization tools that use phasor or other data; other types of remote sensing, monitoring, data acquisition and retrieval equipment; planning and control room applications; advanced communications and interconnection systems; and retrofit of electric transmission systems with smart grid functions and capabilities.
Projects in this topic area produce or purchase smart grid systems, equipment, devices, software, or communications and control systems for modifying existing electric system equipment; building, office, commercial, or industrial equipment; consumer products and appliances; or distributed generation, demand response, or energy storage devices to enable smart grid functions.
