The local power utility is delaying the rollout of Dunedin, Florida, Wi-Fi network: The company that the city contracted to install a Wi-Fi network has been unable to secure an agreement so far with Progress Energy, which controls the poles. The city thought it owned the poles, but had given them to the energy firm three years ago. This isn't unusual: the pole rights are governed by a variety of regulations, and sometimes utilities accept maintenance responsibilities in exchange for easier access for their own purposes.
The energy company isn't per se opposed to having Citi WiFi, the contractor, put Wi-Fi transmitters on its poles. But they don't have a streamlined process for it and they have to conform to the rules set by FCC and state rules. These rules usually require certain kinds of non-discriminatory access mediated by space on the poles and other factors.
Update: City WiFi's Frank McCarthy wrote to correct a few details. First, as the article I link to notes, City WiFi currently has approval for 8 of 10 poles they requested. Second, there is Wi-Fi service running now with transmitters on city-owned buildings and other facilities; that started up in June.
Third, Progress Energy initially stated that City WiFi would never get access to any power distribution poles; that's changed. PE is apparently now saying that City WiFi still can't have access to light poles, but McCarthy expects that position to change with negotiation, too. City official are committed to making this happen, and their political pressure is apparently helping.
City WiFi's experience should be both a cautionary tale of dealing with utilities that have their own agenda and regulations, and a point of optimism that politicians can provide a push to cut through delays and recalcitrance.
