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.

What 1-second data can tell you about voltage and solar
By Suzanne Russo, CEO, Pecan Street One topic we’ve been focusing on recently is voltage stabilization. It’s not sexy, but it’s important. In short, the goal is to keep voltage on the grid as constant as possible. A number of things upset that constancy, and operators have developed a number of responses, from load shifting to capacitor banks, reactors and more.

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.
