This technical brief discusses various aspects of hydropower, including technologies, market outlook, capital costs, operations and maintenance costs, regulations and policies, and R&D.
To reduce compliance costs and increase regulatory certainty, private landowners can take voluntary pre-listing conservation actions—in other words, steps to protect species before they are listed under the U.S. Endangered Species Act. This report discusses nine case studies of voluntary activities covering different species, regions, and situations. Four of the cases are electric power companies.
This study describes state-of-the-art sensor technologies for monitoring the quantity and quality of freshwater resources. These include sensors that monitor common parameters such as discharge, temperature, conductivity, pH, turbidity, nutrients, and dissolved oxygen. The sensors’ measurement ranges, advantages, and disadvantages are also discussed.
Numerous water “footprinting” tools are available to help organizations inventory their water withdrawal and consumption and conduct risk assessments. This study reviewed these tools to determine their suitability for the electric power industry.
This white paper discusses various aspects of smart inverters, including voltage regulation, technical application, communication and control needs, and economic considerations.
Founded under the auspices of the National Science Foundation, GRid-connected Advanced Power Electronics Systems (GRAPES) is an R&D program that aims to accelerate the adoption of power electronics–based controllers in the electric grid to improve system stability, flexibility, and robustness. The program is operated by The University of Arkansas, the University of South Carolina, and the University of Wisconsin-Milwaukee. This report summarizes current GRAPES projects.
This study examines the deployability of sol-gel technology, which is used to fabricate coatings on power plant components that function as ultrasonic sensors.
In this paper submitted to Energy Economics, EPRI researchers compare the cost-effectiveness of renewable portfolio standards in reducing CO2 emissions to that of cap-and-trade policies.
Power plants are under increasing pressure to reduce freshwater use, and desalination technologies may provide an alternative water source. This report discusses water quality needs in fossil-fired power plants, mature and emerging desalination technologies, and research needs.
Regions with higher-than-normal carbon content as a result of macrosegregation (variations in composition in alloy castings or ingots) have been found in large forged components in pressurized water nuclear reactors. This study assessed whether such macrosegregation would jeopardize design margins in nuclear plant operations.
This study lab-tested probes for monitoring flow-accelerated corrosion rates in power plant components.
Flexible operation of power plants has increased the need for efficient plant maintenance. This report provides an overview to data analytics as applied to plant maintenance and technology, identifying opportunities for improvement as plant operators transition from scheduled maintenance to condition-based maintenance.
