OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Improving Infrastructure Service Quality with Smart Technology: Evidence from Electricity Grid Investments in Texas
“Electricity outages are on the rise in the U.S. due to climate change and an aging infrastructure, creating substantial economic and social losses. We provide some of the first empirical evidence of how advanced metering infrastructure—a communication network comprised of smart meters and data management systems that provide real-time information on electricity production and consumption—enhances grid reliability. To do so, we use granular data on power outages and implement a difference-in-differences research design to study smart meter rollouts in Texas. We find that they do indeed improve reliability, and the effects are economically meaningful. On average, the duration of outages decreases by 6 percent. While there is no effect on outage frequency on average, this masks substantial heterogeneity. Outage frequency and duration decrease by 7 and 12 percent, respectively, when a high proportion of meters are “smart”. We also show that the effects are overwhelmingly driven by utilities leveraging the technology rather than consumers. When utilities are able to execute load control by shutting down customers’ equipment on short notice, smart meters reduce outage duration by 55 percent and frequency by 16 percent, whereas providing consumers with easy access to data via a web portal has little to no effect. Our findings suggest that policy enabling utility-side capabilities is important for smart technology to have the greatest impacts on reliability.”
