Rate Schedules & Tariff Analysis
For PWP C&I customers, demand charges and the fixed Grid Access Fee dominate the bill once you cross 30 kW. Primary-voltage schedules (M-2, L-2) carry meaningfully lower per-kW demand charges than their secondary counterparts ($11.49-$11.89/kW vs $16.09-$18.76/kW), so customers able to own/operate transformers and take primary service can cut demand costs. Time-of-use energy spreads are modest (roughly 1-7%), so the largest savings lever is peak-demand management, not energy arbitrage.
Pasadena Water and Power (PWP) Rate Schedule List
| Schedule | Applicability |
|---|---|
| S-1 Small Commercial & Industrial | C&I demand <=30 kW; flat or TOU energy; no demand charge. |
| M-1 / M-2 Medium Commercial & Industrial | 30-299 kW; demand charge $16.09/kW (sec.) or $11.49/kW (prim.). |
| L-1 / L-2 Large Commercial & Industrial | >300 kW; TOU energy; demand charge $18.76/kW (sec.) or $11.89/kW (prim.). |

Pasadena Water and Power (PWP) Data Access FAQ
Can a commercial energy consultant get my PWP usage data?▾
Yes. PWP supports two paths: add the consultant as an Authorized User (Commercial) in MyMeter, or submit a written, customer-signed data request to WPD_Answerline@cityofpasadena.net. PWP typically returns billing and usage data within 5-10 business days, and whole-building AB 802 data within 30 days.
Does PWP offer interval (15-minute) data for C&I accounts?▾
Not yet. PWP currently provides daily aggregated usage in MyMeter. Granular 15/30-minute interval data is expected after PWP completes its AMI smart-meter deployment (estimated 2026-2028), at which point Green Button download and Connect My Data are planned.
Is there a demand charge on PWP commercial rates?▾
Yes. PWP's Medium (M-1/M-2) and Large (L-1/L-2) C&I schedules bill a per-kW distribution charge against monthly demand (for example $18.76/kW on L-1 Secondary as of the 10/01/2025 winter rate card), plus a fixed monthly Grid Access Fee. Managing peak demand directly reduces these charges.
Can I get whole-building data for ENERGY STAR benchmarking?▾
Yes, under California AB 802. If your building is 50,000+ sq ft or has 5+ active utility accounts, request the Building Energy Use & Public Disclosure form from PWP; they deliver Portfolio Manager-ready data within 30 days of a complete request.
Does PWP have retail electric choice / supplier shopping?▾
No. PWP is a municipal utility, so electricity is provided as bundled service under City Council-approved rate schedules. There is no competitive retail supplier shopping or CCA within the PWP territory.
