does solar increase costs for other energy users?If you've ever read about renewable energy on your local online message board, you've probably heard the claim that solar increases electricity costs for everyone else. The utilities' trade association even ran a controversial television advertisement in which an actor stated, "I shouldn't have to pay for my neighbor's solar." So - does solar increase costs for others? Is this notion actually true?

How Solar Works With Utilities

When people go solar, they are usually still tied to the grid. Thus, customers can receive electricity even if their panels aren't producing enough to meet their usage demands. Overall, the more people install solar, the lower the stress on the grid. By slowing demand for utility-provided energy, solar also reduces infrastructure update needs. Best of all, solar decreases the amount of time utilities must turn on dirty power plants. So if that's true, how could solar increase costs?

Well, when customers switch to solar electricity, they pay utility companies far, far less in monthly electric bills: often, nothing at all! And many utilities must buy energy back from people whose solar arrays overproduce due to net metering programs. Surprisingly, however, decreased demand doesn't affect utilities' income.

How Utilities Make Money

According to The Freeing Energy Project, utilities are "government-granted monopolies with exclusive rights to sell electricity in their assigned regions." Utilities actually don't make money based on how much electricity they sell. Instead, their profits come from "investment in the assets (the pipes, substations, transmission lines, etc.)" that provide electricity (Sightline Institute). Public officials and utility commissions highly regulate utility companies to ensure fixed prices for consumers. These government agencies also determine how much to pay the utilities, often via archaic formulas that disincentivize utility companies to innovate, improve efficiency, or optimize existing systems.

When profits are down due to solar adoption, what can utilities do? Their only option is to levy fees on their existing customers in an attempt to recoup the so-called "lost costs" of clean energy programs.

So while it's true that people may see increased electricity costs, it's not accurate to attribute those to solar installations. The utilities made a choice to pass their lost revenue through to their customers.

The Real Issue

Like any outdated industry, utility companies desperately need to update their business models to accommodate change. For example, performance-based regulation (PBR) may be a better system for everyone involved, but utilities and government have been slow to modernize. Massachusetts is a leader on this front, with both Eversource and National Grid beginning to implement PBR components. However, the switch is still a work in progress. These companies' failure to adopt metrics for achieving state climate goals led to criticism that the "Massachusetts utilities can get automatic rate increases without doing anything differently" (UtilityDive).
