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. Even in the legislative and regulatory universe, VPPs are considered tomorrow’s technology and have not yet been fully integrated into grid planning efforts. They should be.
A Plan for a 21st Century Grid – Part 4: A Strong, Resilient Grid Starts With a Plan
By Scott Hinson, chief technology officer, Pecan Street – In Texas and across the country, customers deserve a grid that will keep us warm during the next Uri, that will rebound quickly after the next tropical storm, and that will keep us cool during ever-hotter summers. One that’s stronger, cleaner, cheaper and smarter. And that will take a plan.
A Plan for a 21st Century Grid – Part 3: Fossil Fuel Thinking is Clouding Our Future
By Scott Hinson, chief technology officer, Pecan Street – Despite the catastrophic failure of natural gas power plants during Winter Storm Uri, fossil fuel electricity generators are still considered more reliable than other electricity solutions, be it solar, wind, batteries, demand response, etc. The state’s biggest solution to Uri was a multi-billion dollar investment in….more gas plants.

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.
A Tale of Two February Freezes – Can Last Year’s Grid Failure and This Month’s Storm be Compared?
By Scott Hinson, chief technology officer, Pecan Street – The recent freeze gave us an opportunity to compare electricity use in our research network before and during the event to how people used power during last year’s crisis. Did they learn any tips or tricks? Did they panic heat their homes to prepare for power outages? Did they charge their cars any differently? Here's what we saw.
