Connecting Energy Data with Voices of Real Homeowners
Guest Blog by Hannah Danaë Goodman of CAPA Strategies – No one likes to spend on their energy bill, but for many families across the country, utilities aren’t just an inconvenience but a huge financial burden. For families living paycheck to paycheck, high energy bills can be a serious source of stress that forces them to do burdensome mental math about cutting costs in other areas, finagling payment plans, or reaching out to family members for assistance.
Achieving Affordability, Resilience and Abundance with Virtual Power Plants
By Cavan Merski, data analyst, Pecan Street – The transformative potential of virtual power plants (VPPs) is poorly understood. Your average electricity customer has no idea what VPPs are.

Canary Media: Smart Electric Panels in Homes Could Prevent Overtaxing the Grid
Canary Media – Utilities are worried that homes switching to electric heating, electric cooking and electric-vehicle charging will create major new strains on their power grids. And homeowners looking to go all-electric face steep costs if they need to upgrade their grid connections to handle bigger electrical loads. A new report suggests that both problems could be addressed by the latest smart electric panels.
During Texas’ Heatwave, Every Degree Matters. And so Do Conservation and Efficiency.
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.
More Clean Power in Texas will Require More Grid Transmission and DER Development
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.
