Every Year You Wait, the Deal Gets Smaller: SCE’s Net Billing Adders Phase Out After 2027

Every Year You Wait, the Deal Gets Smaller: SCE's Net Billing Adders Phase Out After 2027

California's income-qualified net billing adders, the extra export incentive payments layered on top of standard NEM 3.0 credits for qualifying households, aren't permanent at their current levels. Like many state solar incentive programs, they're structured to decline over time, with current program rules pointing toward the adder benefit phasing down and eventually phasing out after 2027 for new applicants.

Why incentive programs are typically designed to shrink over time

Regulators generally design incentive programs this way intentionally, front-loading the highest incentive levels to accelerate adoption while the market is still developing, then reducing incentive value as solar becomes more mainstream and, in theory, more affordable on its own. It's the same basic structure that's applied to the federal solar tax credit and to standard NEM programs over the years, where earlier adopters received better terms than those who installed later.

What "phasing out" actually means for a homeowner's timeline

For income-qualified adders specifically, the practical implication is that a homeowner who applies and gets a system installed before the phase-down begins locks in a materially better financial deal than a homeowner who waits and installs the same system a few years later, even if both households qualify for the same income-based program. The adder amount that applies to a given system is generally fixed at the time of interconnection, meaning early applicants under the current, richer terms benefit from those terms for the life of their system.

Why this timeline pressure is easy to overlook

Unlike a headline deadline with a hard cutoff date, gradual program phase-downs don't generate the same urgency in most homeowners' minds. It's easy to assume there's no rush since the program isn't disappearing overnight, but the actual dollar value available to a new applicant shrinks with each passing program year as adder levels step down toward the eventual 2027 phase-out.

What this means for income-qualified households considering solar

For homeowners who believe they might qualify for income or home-qualified net billing adders, the financial argument for moving relatively soon rather than waiting indefinitely is straightforward: the same system, installed later, is likely to come with a smaller adder benefit attached to it, permanently, for the life of that system.
