A key obstacle to implementing augmented reality systems at the enterprise level is the emergence of proprietary technology. This report evaluates the requirements for and approaches to deliver interoperable augmented reality data, components, and systems.
Because of low natural gas prices, many coal plants are being asked to operate at low loads, which may present technical challenges for selective catalytic reduction reactors used for NOx control. Vendors set a minimum operating temperature to protect the catalysts in the reactors. The objective of this research was to demonstrate that the reactors can operate for an extended time at a reduced load while maintaining required NOx emissions and without permanently deactivating the catalyst.
Concrete structures can degrade as a result of alkali-silica reactions, and nuclear plants need to develop aging management programs to maintain structural integrity for extended operations. To support that work, this report reviews research on how alkai-silica reactions change the mechanical properties and behaviors of concrete structures.
This series of reports highlights economic, policy, and technology developments likely to impact utility solar investment and planning.
This study investigated the use of data from wireless sensors to support demand response in a large commercial office building at the University of California, Berkeley. Researchers examined optimal sensor density and control schemes for demand response events.
This study examines various practices used by utilities to address energy efficiency resource assessment, renewables integration, natural gas price forecasts, portfolio development, and other key elements in their recent resource plans.
In recent years, power plants have experienced premature failures and severe degradation of metallic and nonmetallic flue gas desulfurization recycle pump internals, often leading to costly plant outages. This study examines the resistance to degradation of various commercial flue gas desulfurization recycle pump materials, including 10 white cast irons and three nonmetallic coatings.
In this study, EPRI evaluated the performance of a new thermal evaporation system (developed by Sylvan Source) in treating wastewater at a natural gas combined-cycle power plant in California.
Configuration management involves identifying and documenting a power plant’s various physical configurations, changes to configurations, and compliance with requirements. Plant operators can use this guideline to assess configuration management policies and procedures and develop new ones.
Laboratory research has indicated that applying flue gas desulfurization gypsum (a by-product of power plant scrubbers) to agricultural fields can reduce phosphorus runoff. In this study, EPRI measured the effectiveness of gypsum at working farms, applying it on eight Ohio farms and monitoring phosphorus concentrations in edge-of-field drainage over three years.
Increasing distributed energy resources in utility portfolios are expected to change electricity costs. Drawing on publicly available data, this white paper examines how costs change over time and as a result of resource mix, utility structure, and other factors. The analysis is intended to inform utilities, regulators, and policy makers as they consider cost recovery strategies that can equitably accommodate growing distributed energy resources.
“Use cases” are valuable for documenting applications and defining requirements for the smart grid. This software automates the importation of utility use cases into a searchable EPRI repository.
