This is the 8th annual report from the United States Department of Energy’s Federal Energy Regulatory Commission (FERC) on demand response and advanced metering in the United States, based on publicly available information and interviews with market participants and industry partners. The assessment reviews penetration rates of advanced metering and communications technologies; existing demand response and time-based rate programs; annual resource contributions from demand resources; the potential for demand response as a quantifiable, reliable resource for regional planning; steps that have been taken in regional transmission planning and operations to ensure demand resources are provided equitable treatment as a quantifiable, reliable resource; and regulatory barriers to improved customer participation in demand response programs.

As part of the U.S. SunShot Initiative—aiming to make PV electricity cost-competitive with conventional generation by 2020—this report analyzes the impact of high-penetration variable generation on the distribution grid, it demonstrates that in most cases DG can be safely integrated at much higher levels than interconnection standards allow. By streamlining interconnection processes, deploying advanced inverter functionalities, and coordinating DGPV, upwards of 350 GW can be hosted on the U.S. grid with little additional hardware. The report also outlines challenges to interconnection such as voltage regulation, power flow, and protection issues. It then studies the role of storage and complementary technologies to overcome reliability constraints. This research is applicable outside of the U.S. in demonstrating how to maximize an existing grid for DG.

Energy Storage
Energy storage refers to technologies capable of storing electricity generated at one time for later use. These technologies can store energy in a variety of forms including as electrical, mechanical, electrochemical or thermal energy. Storage is an important resource that can provide system flexibility and better align the supply of variable renewable energy with demand by shifting the timing of energy supply and demand.
