Diving deeper into power factor
By Scott Hinson, chief technology officer, Pecan Street Residential solar inverters typically only provide real power to the electrical grid. When they do that, the reactive power component (either the displacement or distortion current) isn’t affected. It stays on the grid. The real power draw of the house is minimized or even completely canceled. This means that the utility has to deal with the portions of the load – called reactive power – that reduce power factor.

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.
Finding invisible water (and money) leaks with Pecan Street’s tech
By Rachel Jenkins, director of operations, Pecan Street Most water customers – residents and businesses alike – know how much water they used last month. But they don’t know what used that water, or when. Pecan Street’s equipment lets users see water use minute-by-minute, in near-real time.
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.
A drone (and photographer) visits Pecan Street research families
By Rachel Jenkins, director of operations, Pecan Street Thanks to our friends at Environmental Defense Fund, we spent some time last week shooting new photos of two research families and flying a drone to get some cool footage of all the solar panels around the Mueller neighborhood. Look at all those solar panels!
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.
