In a break from our traditional format of 20-30 minutes (or so), we have a special in-depth interview this week with Harold Depriest, the former CEO and President of Chattanooga's Electric Power Board. He recently retired after 20 incredibly transformative years for both Chattanooga and its municipal electric utility. We talk about the longer history behind Chattanooga's nation-leading fiber network and how the culture of the electric utility had to be changed long before it began offering services to the public. We also talk about the role of public power in building fiber networks.Something we wanted to be clear about - we talk about the timeline of when Chattanooga started to build its network and how that changed later when the federal stimulus efforts decided to make Chattanooga's electric grid the smartest in the nation. This is an important discussion as few understand exactly what the grant was used for and how it impacted the telecommunications side of the utility. But we start with the most important point regarding Chattanooga's fiber network - how it has impacted the community and the pride it has helped residents and businesses to develop. For more information about Chattanooga's efforts, see our report, Broadband at the Speed of Light, and our Chattanooga tag. Read the transcript of the show here.We want your feedback and suggestions for the show - please e-mail us or leave a comment below.
