Pasadena Water & Power · Municipal net metering
PWP net metering, explained for homeowners.
Net metering under Pasadena Water & Power runs on a different rulebook than most of LA County. PWP is a municipal utility, so it is not governed by the CPUC's NEM 3.0 and instead administers its own net metering program with its own tariff. For Pasadena homeowners, that means the export economics are genuinely local and worth modeling against your specific PWP rate schedule rather than assuming SCE's slashed rules apply. The other Pasadena wrinkle is the housing stock — Bungalow Heaven Craftsmans and HPOZ historic districts care how a system looks and often need specialized mounting. Helios models the exact PWP tariff that applies to your address, designs period-appropriate layouts, and the owner signs off on every Pasadena design.
Pasadena Water & Power
How net metering works on PWP.
Pasadena Water & Power is a city-owned municipal utility, which places it outside CPUC jurisdiction and the NEM 3.0 Net Billing Tariff. PWP sets its own net metering terms, so the credit you earn for exported solar is determined by PWP's own program and your PWP rate schedule rather than by the statewide investor-owned-utility rules.
Because of that, the single most important step for a Pasadena homeowner is to model the actual PWP tariff that applies to your address. The export treatment under a municipal program like PWP's can differ meaningfully from NEM 3.0's hourly avoided-cost rates, and it directly changes whether a battery improves your payback or simply adds backup value. We don't assume — we run your specific PWP rate.
Pasadena layers a second consideration on top of the tariff: its housing stock. Many homes sit in HPOZ historic districts or carry tile and wood-shake roofs, where panel placement, visibility, and mounting hardware all matter. We design low-profile, street-discreet layouts and handle PWP permitting and interconnection as part of the job.
Storage on PWP
Should you add a battery?
Whether a battery is worth it on Pasadena Water & Power depends on PWP's specific net metering terms — which is exactly why we model your tariff before recommending one. Under a municipal program, the export-vs-self-consumption gap can be narrower than on NEM 3.0 utilities, so the storage case isn't automatic the way it is on SCE. A battery still delivers outage backup and protection against future PWP rate changes, and for some Pasadena rate schedules it improves payback meaningfully. We run your exact PWP numbers and show you both paths rather than defaulting to a battery upsell.

PWP net metering questions, answered.
- Does Pasadena Water & Power follow NEM 3.0?
- No. PWP is a municipal utility and isn't governed by the CPUC, so NEM 3.0 doesn't apply. It runs its own net metering program with its own tariff, separate from the SCE rules that cover most of LA County. We model your specific PWP rate rather than assuming NEM 3.0 terms.
- How does PWP net metering credit my exported solar?
- PWP sets its own export credit terms under its municipal net metering program, and they depend on your PWP rate schedule. Because they can differ meaningfully from NEM 3.0's hourly avoided-cost rates, we model the exact tariff that applies to your Pasadena address before quoting.
- Is a battery worth it on Pasadena Water & Power?
- It depends on your PWP tariff, which is why we model it first. The storage case isn't automatic the way it is on SCE — a battery still adds outage backup and rate-change protection, and for some PWP schedules it also improves payback. We show you both solar-only and solar+battery on your real numbers.
- Can I put solar on a historic Pasadena home in an HPOZ?
- Usually yes, but placement and visibility matter in HPOZ districts. We design low-profile, street-discreet layouts and handle the added review where it applies, so you keep the home's character and still get the production. We also handle PWP permitting and interconnection.
