Glendale Water & Power · 1:1 retail net metering
GWP net metering, explained for homeowners.
Net metering under Glendale Water & Power is the arrangement the rest of Southern California lost: true 1:1 credit. GWP is the City of Glendale's municipal utility, outside CPUC jurisdiction, and as of 2026 it still credits exported solar at the full retail rate — the deal SCE customers gave up when NEM 3.0 cut export values roughly 75% in 2023. For Glendale homeowners the implication is refreshingly simple: a well-sized solar-only system still pays for itself the old-fashioned way, banking summer surplus against winter usage, no battery required to make the math work. GWP updated its interconnection paperwork effective January 19, 2026 and only accepts the current agreement version; we file it correctly the first time. Helios models your actual GWP rate schedule, and the owner signs off on every design.

How net metering works on GWP.
GWP administers its own net energy metering program: your solar production offsets your consumption, and excess generation earns a bill credit at retail value that carries forward automatically to months when you need it. That 1:1 treatment means the grid still functions as your battery in Glendale — export at noon, draw back at night, even trade.
As of 2026, GWP has no residential NEM waitlist or capacity cap, and while its earlier solar rebates have ended, the 1:1 credit itself is the incentive. The paperwork is specific: interconnection runs through GWP's process with the city's current agreement form (updated January 2026), followed by meter provisioning and permission to operate. We handle the full sequence alongside Glendale's building permit.
One honest caveat belongs in every Glendale conversation: municipal programs can change, and utilities that change them have historically grandfathered existing customers. That asymmetry — current customers keep their terms, future applicants get whatever comes next — is the strongest argument for interconnecting sooner rather than later.
Storage on GWP
Should you add a battery?
On GWP, a battery is genuinely optional — a statement we can't make almost anywhere else in Southern California. With full retail export credit, storing your own power saves you nothing over exporting it, so the battery's value here is outage resilience, EV-charging flexibility, and insurance against future program changes. Plenty of Glendale designs are solar-only by choice, and we present it that way: the panels do the economics, the battery is a resilience decision. If GWP's program ever moves toward net billing, a battery-ready design converts cheaply.

GWP net metering questions, answered.
- Does Glendale still have real 1:1 net metering?
- Yes — as of 2026, GWP credits exported solar at full retail value, with no NEM 3.0-style export cut and no residential capacity cap or waitlist. It's one of the last true retail net-metering programs in Southern California.
- Do I need a battery on GWP in Glendale?
- Not for the economics — 1:1 credit means exporting and storing are financially equivalent. Batteries in Glendale are for outage backup and future-proofing. We show solar-only and solar+battery side by side, and solar-only is often the rational pick here.
- Could GWP end 1:1 net metering?
- It could — municipal boards set their own terms, and programs across California have tightened over time. Historically, changes grandfather existing interconnected customers, which is why acting while 1:1 is in effect matters. We file GWP's current (January 2026) interconnection agreement correctly the first time.
- How do Glendale solar permits work?
- Two tracks run together: the City of Glendale building permit for the installation, and GWP interconnection with the current agreement form and meter provisioning. We manage both, through permission to operate.
