The Deal: Monopoly and the Obligation to Serve

7 min · difficulty 2/10

A new company wants in. It plans to string its own poles and wires down a street the local utility already serves, then undercut the price to win those customers. Before reading on, predict what the regulator does with that plan: green light, or no? And whatever your answer, think about why.

The regulator says no, and the reason is cost, not favoritism. Distribution wires are a natural monopoly. The first set of poles and conductors already runs past every house on the block, so a second competing set just buries and hangs the same hardware twice and serves no new customer. The public ends up paying for both. To avoid that waste, the government grants one utility an exclusive franchise territory, a bounded area where it alone owns and operates the wires.

Franchise territory and the regulated-monopoly bargain An abstract rounded-rectangle service territory. Inside it, one utility's poles and overhead wire serve several homes, with an obligation-to-serve note pointing all the way out to a far, remote home at the edge. A second duplicate competitor line drawn crossing into the territory is struck through with a red X and marked not allowed. One territory, one set of wires the regulated-monopoly bargain Franchise territory One utility's poles and wires Obligation to serve every customer here Duplicate competitor line: not allowed
One utility holds an exclusive franchise territory and must serve every customer in it; a duplicate competitor line is not allowed.

A monopoly with no checks would just raise prices, so the grant comes with strings. The utility does not get to set its own rates. A regulator, usually a state public utilities commission, reviews and approves what it may charge. That is the first half of the deal: an exclusive territory in exchange for oversight on price.

The second half is the obligation to serve. Inside that franchised, regulated territory the utility must connect and serve any customer who asks, at the approved rate, even the ones who cost more to reach than they will ever pay back. It cannot keep the profitable downtown blocks and refuse the lone customer at the end of a long rural road. There is no competitor to send that customer to, so the duty lands entirely on the one provider that holds the territory.

So the bargain is symmetric. The utility gets to be the only game in town, and in return it gives up free pricing and accepts that everyone in its boundaries gets served. Keep that trade in mind. It explains almost every rule the rest of this track covers, from how rates get approved to why a utility cannot simply walk away from an expensive line.

Rate cases, cost-allocation fights, and FERC/NERC jurisdiction shifts move procurement timelines as much as any supply constraint. The Feeder tracks the regulatory and market signals that reset lead times, free, every week.

Why does the government grant one utility an exclusive service territory instead of letting several compete on the same streets?
