The city says that the estimated cost of the construction is between $35 million and $40 million and that the construction of the network should be complete in about two-and-a-half years. The full details of the plan have not yet been released, but the press is reporting that Google Fiber will pay $2.25 per month to the city for each customer that buys service from Google Fiber.
What is most unique about this arrangement is that conduit will be built along streets and into yards and parking lots to reach every home and business. I know of many cities that lease out some empty conduit to ISPs and carriers, but the big limitation of most empty conduit is that it doesn’t provide easy access to get from the street to reach a customer. West Des Moines will be spending the money to build the conduit to serve the last hundred feet.
This business arrangement will still require Google Fiber to pull fiber throughout the entire empty conduit network – but that is far cheaper for the company than building a network from scratch. The big cost of building any fiber network is the labor needed to bring the fiber along every street – and the city has absorbed that cost. The benefit of this arrangement for Google Fiber is obvious – the company saves the cost of building a standalone fiber network in the City. It’s the cost of financing expensive networks up-front that makes ISPs hesitant to enter new markets.
From a construction perspective, I’m sure that the City is building fiber with some form of innerduct – which is a conduit with multiple interior tubes that can accommodate multiple fibers (as is shown in the picture accompanying this blog). This would allow additional ISPs to coexist in the same conduits. If the conduits built through yards also include innerduct it would make it convenient for a customer to change fiber ISPs – disconnect fiber from ISP A and connect to the fiber from ISP B.
The City is banking on other ISPs using the empty conduit because Google Fiber fees alone won’t compensate the city for the cost of the conduit. The press reported that Google Fiber has guaranteed the City a minimum payment of at least $4.5 million over 20 years. I’m sure the City is counting on Google Fiber to perform a lot better than that minimum, but even if Google Fiber connects to half of all of the customers in the City, the $2.25 monthly fee won’t repay the City’s cost of the conduit.
This business model differs significantly from the typical open-access network model. In other open-access networks, the City pays for 100% of the cost of the network and the electronics up to the side of a home or business. The typical monthly fee for an ISP to reach a customer in these open access-networks ranges between $30 and $45 per month. Those high fees invariably push ISPs into cherry-picking and only pursuing customers willing to pay high monthly rates. The $2.25 fee in West Des Moines won’t push ISPs to automatically cherry-pick or charge a lot.
Any ISP willing to come to the city has a few issues to consider. They avoid the big cost of constructing the conduit network. But a new ISP will still need to pay to blow fiber through the conduit. Any new ISP will also be competing against Google Fiber. One of the most intriguing ISPs already in the market is CenturyLink. The company has shown in Springfield, Missouri that it is willing to step outside the traditional business model and use somebody else’s network. I would have to imagine that other ISPs in the Midwest perked up at this announcement.
In announcing the network, the City said that they hoped this network would bring fiber to everybody in the City. Google Fiber doesn’t typically compete on price. Earlier this year Google Fiber discontinued its 100 Mbps broadband connection for $50. Many homes are going to find the $70 gigabit product from Google Fiber to be unaffordable. It will be interesting over time to see how the city plans on getting broadband to everybody. Even municipalities that own their own fiber network are struggling with the concept of subsidizing fiber connections below cost to make them affordable.
One thing this partnership shows is that there are still new ideas to try in the marketplace. For an open-access conduit system to be effective means attracting multiple ISPs, so this idea isn’t going to work in markets much smaller than West Des Moines. But this is another idea for cities to consider if the goal is to provide world-class broadband for citizens and businesses.
