Conservatives should seek to enable and fairly value solar power


Competitive markets are at the heart of American economic prosperity and stability. Unfortunately, this hasn’t been true of the monopoly-led, scandal-prone Arizona electricity industry.

Conservatives should welcome new technologies and regulatory reforms that allow consumer choice and make it possible to compete with monopoly utilities. The Arizona Corporation Commission currently has a big opportunity to do exactly that.

The monopoly model has stifled new product development and consumer choice. Arizonans deserve better, and evolving technologies and consumer preferences merely enhance the value of electricity competition and choice. One such technology is rooftop solar, which allows customers to meet some of their own power needs and, at times, provide excess power to the grid.

Self-generation should be a right for all consumers, who should receive fair compensation for what they put back on the grid, while paying their fair share of grid upkeep costs. Some legitimate concerns have been voiced on these points. But utilities see the current debate as an opportunity to shutter the competition and guarantee the stability of their own revenues. The pending case before the ACC on the value of rooftop solar could either set this situation straight or set the cause of competition and choice back many years.

After a series of battles over rooftop solar, the ACC has deferred judgment to address the issue comprehensively. That’s a good sign, as it avoids knee-jerk reactions to a complex, high-stakes issue. Abrupt responses have already led to disruptive policies in other states, such as Nevada.

It’s critical for the ACC to consider not just the short-term benefits of solar, like the savings from having to operate power plants less, but also the long-term benefits, like reducing the need to build or maintain power plants. Distributed resources like rooftop solar also can make the grid more resilient. This should not be overlooked in a world that faces increased threats from cyber and physical attacks on critical infrastructure.

Not only must the ACC determine the value of solar comprehensively, but how this value is reflected in electricity rates will have a huge impact for customer incentives. Rates should reflect the extent to which customers cause future utility costs. Fixed customer charges send the wrong signal. Utilities prefer them, because they stifle competition and stabilize revenues. But in the long term, they provide no incentive for customers to avoid creating costs for the utility – costs that ultimately are borne by ratepayers. Simply put, if you pay a set amount to be a customer, there’s no value to reduce your demand or to invest in self-generation, despite the money that would save.

The value of solar fluctuates over time and by location. It’s important that the ACC balance this fact against the importance of rate stability. Unpredictable rates increase investment risk and deter innovation and deployment. This stands in contrast to the minimal risk facing utilities, where the monopoly model guarantees they can recover the cost of any investments Arizona regulators deemed prudent. This asymmetric treatment favors utility investment over customer investments.

Ultimately, mounting customer, economic and technological pressures warrant a holistic revision of the monopoly model. While Arizona explored full adoption of a competitive electricity model in 2013, it’s time to re-examine it more seriously. Until then, the ACC’s pending decision will be critical to whether the state moves in the direction of competition and consumer choice.

Competition and choice are fundamental tenants of economic success. This platform serves to benefit all customers, and should especially catch the eye of conservatives. May the ACC act boldly and lead Arizona out of the shadow of monopoly control and into the light of the marketplace.

  1. Solar energy that replaces fossil-fuel energy also hugely reduces the state’s carbon footprint, thus doing our part to slow climate changes that disfavor Arizona: rising temperatures requiring the use of more cooling ,a spiral downward that Arizonans can no longer afford.

  2. James Richard Tyrer

    Conservatives believe in the basic principles of economics, not Green ideology. That means that we understand that a utility is a natural monopoly; that a regulated monopoly utility provides electric service at lower cost (the average cost) than the marginal cost under competition would.

    Much of what he said makes little sense but I think that he is talking about wanting for the electric utilities to continue to subsidize residential solar power with Net Metering. This simply will not work as more and more people install rooftop solar. Who is going to pay for the subsidy? If solar resulted in lower costs for the utilities, this would show up on their books, but it isn’t. What is showing up on their books are higher costs due to solar as they need to build new natural gas power plants to use for backup power for solar.

    The per kWh charge on your electric bill is not just for the electricity. It is a bundled charge for electric service. Only about slightly less than half of it is for the actual electricity. So the best way to end Net Metering would appear to be to charge solar customers the standard price per kWh for electric service for the power that they draw from the grid and credit them for a lower price per kWh (estimated at slightly less than 6 cents per kWh) for power that they feed back into the grid. This would end Net Metering and be fair to both solar and non-solar ratepayers.

  3. This would all make sense if in fact public utilities were well regulated. They are not in AZ. They exist as rate-enabled predators. This isn’t Green ideology or classical economics. It’s real-world reality. Get the regulations and regulators in order — that is, change the composition of the current compradore ACC — and the whole grid-solar issue will become less relevant, maybe even wholly irrelevant.

The House has done its part; now it is time for the Senate to pass the Stopping Bad Robocalls Act and get it the President’s desk for signature so it can become the law of the land. That way, we can put consumers back in charge of their phones, restore confidence back into the system, and stop those annoying robocalls.
