Arizona Rejects Tucson Electric Power’s Grid Access Fee For Solar Customers

By Frank Andorka, Senior Correspondent

It’s not often that I get to write something positive about the Arizona Corporation Commission (ACC). For those of you who have followed my work over the years, we’ve had a…contentious relationships at best. Typically, I’m writing about something I view as skullduggery, and the commissoners (particularly on Twitter) have felt compelled to take on a writer from a little-known solar trade publication.

But today is not one of those days. Today, I’m taking my hat off to the ACC for rejecting a grid access charge proposed in 2015 by Tucson Electric Power (TEP) that would have penalized Arizona residents for installing solar energy.

It was another attempt to persuade the ACC that the “cost shift” is a thing, whereby non-solar customers are somehow damaged by solar customers because (say it with me now) “solar customers don’t pay their fair share of grid upkeep.”

Which, as we’ve discussed before, is nonsense. National studies have concluded that the cost shift only happens when 10% of all electricity in a state is generated by solar power, and that is currently only true in five states. And even IN those five states, the cost shift turns out to be fractions of a penny on the dollar.

(If I seem a little testy, it’s because I have spent the better part of the last three years battling what I refer to as “the zombie lie” of the cost shift, and it wears on a fellow having to write a similar story for several different states because state stakeholders don’t seem to get that the cost shift is a complete myth.

But in any case…kudos to the ACC for seeing through the argument and rejecting the Grid Access Charge. With its ally Earthjustice, Vote Solar has been fighting this Grid Access Charge since 2015. In their release celebrating the decision, Briana Kobor, regulatory director at Vote Solar, had this to say:

Arizona’s families and businesses should be able to meet their own energy needs with the state’s plentiful sunshine if they so choose. Solar is an investment that supports local jobs, improves energy security and helps build a competitive new energy economy in the state. We commend the decision to avoid further penalizing solar customers with additional fees.

Since TEP was trying to bolster the cost-shift myth and make it uneconomical for people to install rooftop solar, I personally am taking the win. Congratulations to Vote Solar and Earthjustice for the win – and use tonight to celebrate. Then get back to the grindstone tomorrow. That cost-shift myth won’t bust itself.
