A part of its SunShot program, first unveiled in 2011 with the aim of driving down solar PV system installation costs to $1 per watt, the U.S. DOE last week announced a $220 million grid modernization initiative. Under this, it has created the Sustainable and Holistic Integration of Energy Storage and Solar PV (SHINES) program.
The goal is to develop and demonstrate integrated PV and energy storage solutions that are "scalable, secure, reliable, and cost-effective." It is the first program at DOE to focus exclusively on connecting renewable power to storage.
Under SHINES, DOE has awarded $18 million in funding to six projects. It is hoped they will improve the resiliency, reliability and security of the U.S. electrical power grid, said DOE in a statement released. All projects will be either led by a utility, or include one as a key partner.
"The projects will work to dramatically increase solar-generated electricity that can be dispatched at any time … to meet consumer electricity needs … Achieving the SHINES goals is a critical step in the pathway towards enabling hundreds of gigawatts of solar to be integrated reliably and cost-effectively onto the electric grid," according to the SHINES website.
The biggest beneficiary of the $18 million funding was Austin Energy, which was awarded $4.3 million to come up with a solution for offering solar, to any region or market structure, at a levelised cost of energy (LCOE) of $0.14/kWh, when combined with storage, for example.
See the table below, adapted from DOE, for a full description of all projects awarded funding:
Demonstrate a solution adaptable to any region and market structure that offers a credible pathway to a LCOE of 14¢/kWh for solar when augmented by storage and other distributed energy resource management options.
