New NREL Facility in Denver Aimed at Smart Grid Research
A new, $135 million research laboratory at the National Renewable Energy Laboratory (NREL) in Golden will be a one-of-a-kind facility, enabling researchers to test the impact of new devices and renewable-energy sources on the nation’s electricity grid in a controlled environment, NREL says. The electrical connections in the building will be capable of handling up to 1 megawatt of power, according to NREL officials. The project will enable researchers to test what happens to the nation’s elect...
Achieving Model-Based Design for the Smart Grid
Smart Meters and SCADA Contribute a Big Data Perspective Smart meters and intelligent electronic devices provide granular data about the state of the utility network in near real-time. The availability of such data is in no small part what is making the smart grid, well, smart. Now, this data is being harnessed by utilities for greater customer insight and designs that are informed by performance. In one sense, the smart-grid is a dynamic real-time system that adapts and heals as condition...
Sewer Heat Recovery Provides Low-Cost Recycled Energy
In every urban area, heat that humans have generated to shower, wash clothes, cook, and so on flows underground — in the sewers, making them very warm. Today, sewers represent the largest source of heat leakage in buildings. Even toilet water, which is at room temperature, is warm compared to the ground. Sewer air, pipe material (and thus conductivity), surrounding soil type, and other factors also affect the final temperature of waste water, according to Genevieve Tokgoz, Project Engineer in th...
