Mitigation (avoiding, minimizing, and compensating for impacts on natural resources) is a requirement of the federal Endangered Species Act. Compensatory mitigation is a component of mitigation that occurs after project impacts have been avoided and minimized. This report discusses the regulatory background for compensatory mitigation and summarizes standard practices and tools to quantify impacts and mitigation.
This field study at a Tennessee facility examined the use of guided waves on the hot side of water wall boiler tubes to find anomalies on the cold side.
As a result of growing variable energy sources, more independent system operators, transmission operators, and balancing authorities have modified system reserve requirements. This report discusses these changes.
This report documents enhancements EPRI made to two system restoration decision-support tools: System Restoration Navigator and Optimal Blackstart Capability.
This report provides an overview of major innovative technologies expected to increase the efficiency of the next generation of gas turbine and combined cycle plants in the next 10-15 years. Technologies applicable to the gas turbine are the primary focus. Heat recovery steam generators, steam turbines, and balance-of-plant technologies are also explored.
This research documents the current knowledge of safety hazards associated with battery energy storage facilities, identifies worker and first responder practices at these facilities, identifies knowledge gaps, and discusses future research to promote safety. Researchers reviewed the published literature, codes, standards, and regulations, and conducted interviews with first responders.
This report assesses smart city lighting technology, which includes the control and monitoring of streetlights along with dimming capability, power measurements, and communication.
The high cost of carbon capture and storage technologies has slowed its deployment. This report examines the possibility of one concept proposed to offset the high costs: using the CO2 for energy storage.
EPRI’s cost-benefit analysis framework for microgrids can help assess the value proposition of various microgrid designs, use cases, technology mixes, ownership configurations, and other attributes. This report discusses the framework’s application, design parameters, assumptions, and modeling stipulations along with findings, takeaways, and lessons for two microgrid feasibility studies.
This research assesses the costs and benefits of implementing autonomous smart inverter functions to control their power output. Results are intended to inform (1) investment and operational decisions aimed at increasing distribution solar adoption and (2) decisions related to compensation mechanisms for distributed energy resources.
Western pressurized water nuclear reactors (PWRs) use lithium-7 to control the pH of coolant water and minimize corrosion of fuel and materials. Because of vulnerabilities in the lithium supply, nuclear plant operators are considering potassium hydroxide as an alternative. This research aims to identify the experiments and documents necessary to qualify the application of potassium hydroxide with nuclear fuel in PWRs. The report consists of a literature review and a description of fuel reliability requirements.
This research evaluated two nondestructive evaluation technologies—dynamic response spectroscopy and pulsed eddy current—that do not require direct contact with power plant components and can be used to examine them through carbon-fiber-reinforced polymer and insulation.
