SGIP: the California rebate buyers forget to ask about

The Self-Generation Incentive Program is the storage rebate that shows up on some California quotes and is quietly missing from others. Whether it applies to you is not a mystery, but it is specific.

SGIP pays a rebate per kilowatt-hour of installed storage, and the rate depends on which budget category you fall into. The general market rate is the smallest. The larger rates are reserved for equity customers and for equity resiliency, which is aimed at households in high fire-threat districts, on medical baseline, or facing repeated public safety power shutoffs.

Why it goes missing on quotes

Two reasons. First, general-market SGIP budgets step down as they are claimed, so at any given moment an installer may treat it as too small to bother quoting. Second, the higher-value categories require documentation, so an installer moving fast may skip them rather than help you qualify.

Neither is a reason to leave money on the table without checking.

How to check before you sign

• Confirm your utility. SGIP runs through PG&E, SCE, SoCalGas, and SDG&E territories, each with its own administrator.
• Find your budget category. If you are in a high fire-threat district or on medical baseline, the equity resiliency rate is worth a real conversation.
• Ask the installer to show the rebate as a separate line, not folded into a vague "after incentives" number.

The buyer takeaway

If a quote claims an SGIP rebate, ask which category and rate it assumes and whether your paperwork actually supports it. If a quote is silent on SGIP, that is not proof you do not qualify. It is a question you should answer before the deposit, not after.
