Larger rotor blades in wind turbines are decreasing energy generation costs, but also come with challenges, such as transportation, manufacturability, and reliability. This report provides cost-benefit analyses for increasing rotor size in onshore and offshore turbines and evaluates various approaches to overcome these challenges, including use of alternative materials, innovative manufacturing processes, and blade segmentation.
This consumer’s guide lists the various plug-in electric vehicles available today, along with their driving range, charging time, and other characteristics. It discusses the types of plug-in electric vehicles, factors affecting performance, charging considerations, incentives, and more.
The U.S. Environmental Protection Agency recently released new rules for power plant wastewater disposal. This study evaluated various arsenic removal media for flue gas desulfurization wastewaters to help meet the rule’s arsenic limits.
It is expected that greenhouse gas rules in the United States will require power plant operators to report emissions and heat rate using continuous emissions monitoring systems, but there is debate about the accuracy of these measurements. This study characterizes the uncertainties and recommends best practices for operations, calibration, and maintenance to improve data accuracy.
Over the next several years, the federal Coal Combustion Residuals Rule will trigger the closure of many utility-operated coal ash ponds, and groundwater monitoring will likely reveal the need for corrective actions such as barrier walls and geochemical manipulation. This report identifies and evaluates groundwater-related corrective actions that could be integrated with pond closure, with discussion of relevant technologies, expected outcomes, cost estimates, and more.
The process for designation of critical habitat—areas essential to the recovery of species protected by the U.S. Endangered Species Act—has been inconsistent. This report explains the critical habitat concept, including its scientific basis, designation practices, methods, and tools. It draws on scientific literature reviews and interviews with conservation biologists and federal agency personnel involved with designation.
This report presents the results of Pepco’s 22-month Demand Management Pilot for Electric Vehicle Charging, which enrolled 101 utility customers in Maryland. The pilot implemented various charging technologies and studied customer responses to different rates intended to shift charging to off-peak periods.
This field guide for visual inspection of condenser components provides numerous photographs to help power plant personnel identify common failures.
This research investigates the advantages, disadvantages, relative costs, and relative water conservation potential of water-saving technologies and strategies used in the agricultural, public, and industrial sectors. It is intended for electric power industry managers and engineers who want to reduce water use at their facilities and learn more about water savings potential in other sectors.
This white paper is a year-one update on a multi-year EPRI project to develop an “open enabling platform” to support secure interoperability and connectivity across the electricity infrastructure.
This report presents the results of testing Television White Space—unoccupied broadcast channels in the very high frequency (VHF) and ultra-high frequency (UHF) bands—for utility communications applications.
This report describes the status of microgrid development in North America, including planned and operational projects. It also discusses the various types of microgrids and their benefits.
