The differences between renewable energy and renewable power in North Carolina

Michael Giberson

Under North Carolina’s Renewable Energy and Energy Efficiency Portfolio Standard, poultry waste burned to boil water to generate steam to turn a turbine generating electricity will earn RECs which can be sold to electric utilities needing to meet the state’s new renewable energy standard. Also under the law, poultry waste burned to boil water to generate steam to be used directly as process heat in factories does not qualify to earn RECs. The distinction may frustrate plans to use the poultry waste as an industrial fuel.

The Raliegh, N.C. News-Observer reports:

An energy company that wants to burn poultry waste for fuel has lost its bid to use the bird droppings as a green energy resource because of a quirk in North Carolina law.

A ruling by the N.C. Utilities Commission means that Peregrine Biomass Development will scrap plans for now to build several industrial boilers in the state. The company had planned to burn chicken droppings as an organic fuel to generate steam for factories and other industrial applications….

Peregrine’s business model had counted on a dual revenue stream. The company had planned to sell steam to industrial customers and at the same time sell renewable energy certificates from the projects to Progress Energy, Duke Energy or regional power agencies. The renewable certificates are a subsidy to encourage development of the state’s renewable sector. Electric companies and power agencies are required to buy a certain amount of the certificates to meet the state’s renewable energy targets.

The state’s 2007 renewable energy law considers poultry waste a type of renewable resource – but only as long as the poultry waste is used to generate electricity. Peregrine’s use of poultry litter didn’t qualify as a renewable, the utilities commission ruled Friday, because the company planned to generate steam or boiling water, not electricity.

An irony here is that Peregrine’s projects would qualify for the REEEPS subsidy if they planned to boil water to generate electric power and then use the electric power to boil water, even though the extra step would involve significant additional up-front cost and be a much less efficient use of the energy source.

John Whitehead at Environmental Economics wonders what “bureaucratic-political rent seeking led to this decision” by regulators, but I suspect it is just an example of how hard it is to provide simple incentives in a complex world. State lawmakers were trying to encourage the electric power industry to rely more on renewable energy sources, so they wrote a law about electric power.  Peregrine’s approach was outside their immediate scope of interest at the time. Perhaps Peregrine can incorporate a cogeneration component to their projects, and claim a subsidy that way, or if the projects will reduce overall energy consumption they might qualify as energy efficiency programs.

By the way, the energy efficiency component seems to me to be a – what is a nice way to say “scam” – in the making. In the regulatory rule-making process at the state utility commission, Duke Energy argued that because it will take time to measure and verify energy efficiency results the utilities should be able to rely on estimates of reduced energy consumption in annual compliance reports, with “actual results” incorporated into subsequent reports. The commission added the following language to the regulations: “REPS Credits for energy efficiency may be based on estimates of reduced energy consumption through the implementation of energy efficiency measures, to the extent approved by the Commission.” (p. 60 in this NCUC order).

So essentially, a utility can get credit for its estimated reductions in energy consumption due to energy efficiency plans implemented, and maybe (though the changes to the regulations say nothing about this) eventually, a subsequent report will list “actual results.” At the least this mechanism allows a way for the utility to borrow credits from future years (by over estimating results now and then over-complying later to make up for the post-verification adjustment), but nothing in the rule governs this potentially significant program component other than the phrase “to the extent approved by the Commission.”

The whole thing is a mess, and not just because of the poultry waste.  Better policy pursues the externalities associated with electric power production – the law here mentions diversity among energy resources and improved air quality as among the policy goals – and let producers and consumers sort out the complexities.  Sure, implementing Pigovian taxes and Coasian bargains can be messy, too, but then sorting out the mess seems to be more about identifying and solving problems rather than about how to fit nicely into the economic framework imagined by lawmakers and regulators.

Cole on Coase and cattle

Michael Giberson

Arizona is re-thinking its open range law. Dan Cole, blogging at Law, Economics & Cycling, is reminded of Ronald Coase (and specifically Robert Ellickson’s law review article “Of Coase and Catttle“). Cole summarizes the situation:

Arizona is an “open range” state, which means that cattle can roam at will. Ranchers do not have to fence them in (but they are responsible for collecting wandering cattle) neighbors must fence them out. From a Coasean point of view, roaming cattle and the harm they cause constitutes a joint-cost problem created by both cattle ranchers and neighbors. The chief solution to the problem is for someone to build a fence. The chief question is: who should have to bear the costs of building and maintaining fences. Ultimately, what “open range” laws do, by insulating cattle ranchers from liability (though not as much as the ranchers might believe) for trespassing cattle, is to allocate the costs of fencing out to the neighbors. The fight going on now in Arizona is about changing the law from “fencing out” to “fencing in,” which would basically just reallocate the costs to the cattle ranchers.

The issue is more complicated than who pays for damages to vegetable gardens inflicted by wandering cows.  An important current issue in Arizona is car-cattle collisions. Under “open range” rules, the driver may be liable to damage to the cow, whereas with a “closed range” rule the rancher may be liable to damage to the vehicle.
