Grid Services

Grid operations uses and benefits for electricity storage (storage) include what are often referred to as ancillary services. The following excerpt from a paper provides an overview of how the Federal Energy Regulatory Commission (FERC) defines ancillary services as follows: 

Ancillary services are those functions performed by electrical generating, transmission, system-control, and distribution system equipment and people to support the basic services of generating capacity, energy supply, and power delivery. The Federal Energy Regulatory Commission (FERC 1995) defined ancillary services as “those services necessary to support the transmission of electric power from seller to purchaser given the obligations of control areas and transmitting utilities within those control areas to maintain reliable operations of the interconnected transmission system.”  Rio Grande Renewables and its technology partners are actively involved in the financing and operating energy storage systems at the edge of the grid or distribution feeders on behalf of utilities or private investors.
