Utilities and “rate decoupling”
July 17th, 2008Massachusetts’ Department of Public Utilities yesterday ordered electricity and gas companies to change the way they bill customers: rather than billing them based on how much electricity they use, they’ll charge for electrical distribution based on the cost to keep their distribution systems running.
The government makes the point that while we require utility companies to encourage consumers to save energy, they have a profit motive to do exactly the opposite: they make more money the more power their consumers use. This change will remove that profit motive, encouraging utility companies to promote conservation.
But while it gives utility companies a reason to get their customers to conserve, it removes conservation incentives for the customer — and it’s the customer whose behavior has to change. If your energy distribution bill is the same regardless of how much energy you use, why use less?
Also, look where the utility company stands. It now wants its customers to use less energy, but those customers have no incentive to reduce usage. How can it earn more money? By cutting back service and delivering as little energy as legally possible. Every uninspected transformer, unmaintained power line, and summer brownout means less cost to the company for the same revenue, and thus higher profits.
The state puts itself in the position of a family with an obesity problem, caused by the family’s habit of eating dinner every night at a fast-food restaurant. The problem, as they see it, is that the restaurant manager has no incentive to encourage them to eat less. Their solution? Demand that the restaurant set up an all-you-can-eat burger buffet.
The family begins eating two burgers per meal because hey, why not? The fast-food joint tries to get the Smiths to eat less, but the family has no reason to listen. So the manager starts cutting costs. One day, they’re out of root beer. The next, no cheese. The day after that, sorry, no meat patties today, but we’ve got plenty of plain buns… And so on.
Energy usage is controlled by the customer, not the energy company, and the utility company’s best interests are rarely the public’s, no matter what pricing scheme is used. There are two ways to make the consumer use less of something: ration it, or make it cost more. The first option is off the table: a large state energy tax is an option that, while unpleasant, might actually work.
