FERC Order 784 is a final rule from the United States Department of Energy’s Federal Energy Regulatory Commission (FERC) that outlines revisions to its regulations to foster competition and transparency in ancillary services markets. The revision affects market-based rate regulations, ancillary services requirements under the pro forma open-access transmission tariff (OATT), and accounting and reporting requirements. The changes proposed also modify the accounting regulations to increase transparency for energy storage facilities.

This report provides a comprehensive examination of market and policy barriers that hinder the use of demand response resources to provide bulk power system services (including ancillary services) in U.S. energy markets. The report introduces a typology that identifies barriers (e.g., bulk power system service definitions, revenue availability) according the relevant power system entities (e.g., balancing area authorities, investor-owned utilities, end-use consumers) that are responsible for and/or affected by the barrier. It also identifies actions required to overcome each barrier. In order to illustrate the differences in and approaches to addressing barriers among various wholesale and retail market designs, four regions are explored as case studies: Colorado, Texas, Wisconsin, and New Jersey.

Estimating the benefits and costs of achieving significant deployment of distributed PV helps power system stakeholders evaluate regulatory measures and compensation programs for distributed PV. To inform these decisions, this report describes current and potential future methods, data, and tools that could be used with different levels of sophistication and effort to estimate the benefits and costs of distributed PV from the utility or electricity-generation system perspective. Although the report is explicitly written in the context of informing estimation of distributed PV costs and benefits to the United States electricity system, the discussions of the various methods, level of effort, and data and modeling requirements provide insights relevant to power systems outside of the U.S. The report provides methodologies for estimating distributed PV benefits and costs for the following categories: energy, environmental, transmission and distribution losses, generation capacity, transmission and distribution capacity, ancillary services, and other factors.

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.

This case study discusses the potential of small, run-of-river hydropower to provide network frequency and voltage control. Included are estimates of the ability of small hydropower to provide ancillary services. The report finds that failure-free and redundant communication equipment to pool and operate hydropower plants are necessary.

This document explores the benefits of expanding co-optimization of energy and ancillary services to hydropower. The author builds off of practices currently enacted for conventional generators and demonstrates that co-optimization improves the economics of hydropower plants.

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.

This report describes the state-of-the-art with respect to variable generation integration, mostly focused on the United States but also providing a few international examples where particularly relevant. The report is predominantly based on an extensive literature review with input from General Electric (GE) and PJM. Pages 97–119 focus on forecasting.
