By Scott Hinson, chief technology officer, Pecan Street – For the second time in a week, Texas’ grid operator (ERCOT) and local utilities yesterday issued “calls for conservation” as the state bakes under a prolonged heatwave. Among the requests: increase your thermostat setpoint to 78 degrees to reduce state-wide air conditioner load. It’s unsurprising that air conditioning increases electricity demand during a heatwave. But it may surprise you to know just how powerful a driver it is and how close it can push the state toward a real problem.
By Cavan Merski, data analyst, Pecan Street – To allow better access and more sophisticated analysis of this data, we launched our own Jupyterhub, a multi-user server for Jupyter Notebooks designed to support large-scale analysis by using GPU and memory based on a server rather than a local machine. It also allows multiple users – like groups of students or researchers – to share the same document at the same time.
By Cavan Merski, data analyst, Pecan Street – The ERCOT power grid is back in the news. Texas experienced its hottest May on record and June has seen consistent record-breaking temperatures as well. ERCOT has been busy trying to balance extremely high grid demand with various electric generation plant outages. On June 12, ERCOT recorded its highest ever grid demand of over 75GW. That record only lasted one week before grid demand climbed to more than 76 GW on June 20. And we’re wasting emission-free wind and solar power.

Pecan Street Inc. and GAVA were selected by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) to participate in the Solar Energy Innovation Network (SEIN) to discover transformative ways of accelerating equitable residential solar adoption in historically underserved communities. Seven other projects around the country were selected to participate in the SEIN program.
