Pecan Street to Conduct Field Testing and Data Management for $2.9 Million ARPA-E Study on HVAC Efficiency
Austin-based Pecan Street Inc. will conduct the field testing and data management for a University of Michigan study that will tackle two of the electricity industry’s biggest – management of renewables intermittency and management of heating, ventilation and air conditioning (HVAC) load growth – the latter of which is projected to be one of the top drivers of global electricity demand and carbon emissions over the next few decades.
Pecan Street Launches Texas’ First Grid-Connected Vehicle-to-Grid Research and Testing Center
Pecan Street Inc. launched Texas’ first grid-tied vehicle-to-grid (V2G) testing center at its lab in Austin, Texas, turning electric vehicles into a dispatchable load shaving tool for municipally-owned electric utility, Austin Energy.
Tendril Acquires EEme to Unlock Appliance-Level Energy Insights
EEMe CEO and founder Enes Hosgor told Greentech Media in 2015 that its Pecan Street tests broke new ground for the energy disaggregation industry in terms of the scale and openness of its testing. “If you don’t have that insight in public, you cannot have a benchmark, a reference point, to move the entire knowledge base forward,” he said.
Live from Texas, it is “Vehicle-to-Grid”!
By Andrea Tosi, power systems specialist, Pecan Street We hit an important energy milestone recently with the installation of an electric vehicle (EV) charger that can charge from and discharge to the grid – a bidirectional flow of energy known as Vehicle-to-Grid, or V2G. For the first time in Austin, and possibly in Texas, energy was transferred from an electric vehicle’s battery pack to the electric grid’s distribution feeder.
Power factor – a little known feature of a reliable grid
By Scott Hinson, chief technology officer, Pecan Street Power factor is a measurement distribution engineers use to figure out how difficult it is to provide power to whatever we plug in. Every device that pulls electricity from the grid, from a small phone charger to large industrial loads, has a power factor that can be measured. Exactly what is power factor (or PF)? The easiest way to understand it is to see it.
Big data, anyone? Pecan Street hits petabyte territory.
By Grant Fisher, chief information officer, Pecan Street We can say we collect 10 million records per-day, per-house. Or, we can say the database is many terabytes large. Or that we have the world's largest collection of energy, water, and gas data for use by academic researchers. However, it isn't until recently that I think Pecan Street has crossed into the “Big Data” realm.
Home energy research opportunity for Ithaca area residents
Thanks to a consortium of funders led by the Alfred P. Sloan Foundation, Pecan Street is expanding its home energy research network to California’s Bay Area and the Ithaca area in upstate New York.
GCN.com – Can electricity use predict a bad morning commute?
Why are some morning commutes so much worse than others? New research shows that nighttime and early-morning energy use can be a good predictor of morning traffic congestion. Sean Qian, an assistant professor of civil and environmental engineering at Carnegie Mellon University, and Ph.D. student Pinchao Zhang created a model that mined data on electricity consumption from 322 homes in Austin, Texas, and used artificial intelligence to predict what traffic would look like the next morning.
Pecan Street Inc. Brings Energy Research to Upstate New York and California’s Bay Area
(AUSTIN, TX – August 1, 2018) – A $1.1 million grant from the Alfred P. Sloan Foundation will allow Pecan Street Inc. to expand its groundbreaking home energy research network into New York and California. Lawrence Livermore National Laboratory, Cornell University’s Atkinson Center for a Sustainable Future, Precourt Institute for Energy at Stanford University, and […]
Restarting Homeplug
Your eGauge energy data collection system reports data back to Pecan Street’s servers using Power Line Communication (PLC), where the data collected by the eGauge is transmitted through your power lines to a device called the Homeplug. The Homeplug retrieves that data from the wall outlet and sends it to your router/modem via ethernet cable, […]
