This report summarizes a three-year, U.S. Department of Energy commissioned study that assesses the value of hydropower to the U.S. power system for both pumped and traditional plants. The report includes an assessment of the current market structures and costs and ways to increase the value of hydropower.
Located in Topics & Resources / Flexible Generation / Flexible Generation folder
This report examines the broader role of hydropower in the U.S. power system in terms of both energy and ancillary services, and how these roles vary across regions, especially under the context of greater variable RE. The report looks at the drivers and barriers to hydropower generation within these markets.

Standard IEEE 1547 is an example of an interconnection standard (commonly used in North American power systems) providing technical rules for interconnecting distributed generation resources with the electric grid. The standard’s guide introduces the background and rationale for the technical requirements, facilitates use of the standard by characterizing distributed resource technologies and related interconnection issues, and provides approaches and information to support interconnection and implementation. The standard was updated in 2014 with an amendment providing existing information on voltage, voltage regulation, and frequency.

High penetration of DPV often leads to the infamous “duck curve,” the formation of two daily peaks in the morning and evening when PV is not available. This easy to read report assesses a variety of options to mitigate the “duck curve” from targeted efficiency, time of use rate design, storage, demand response, balancing, and complementing DPV with peak-oriented renewables. Implantation of these recommendations flattens the demand curve, allowing for additional DPV.

Affordably integrating high levels of variable renewable energy (VRE) sources such as wind and solar requires a flexible grid. Storage and demand response provide means to better align wind and solar power supply with electricity demand patterns: storage shifts the timing of supply, and demand response shifts the timing of demand.
