Rate Schedules & Tariff Analysis
Tacoma Power offers some of the lowest electric rates in the country thanks to its predominantly hydroelectric supply. For C&I customers, the key lever is matching voltage level and load profile to the right schedule: stepping from Schedule G to HVG or CP can roughly cut the energy rate by 20-40% in exchange for taking higher-voltage service and accepting demand obligations.
Tacoma Power Rate Schedule List
| Schedule | Applicability |
|---|---|
| Schedule G - General Service | Demand-metered commercial; $0.058014/kWh + $10.37/kW. |
| Schedule HVG - High Voltage General Service | High-voltage service; $0.045729/kWh + $6.45/kW. |
| Schedule CP - Contract Industrial | Negotiated contract; $0.034198/kWh + $6.22/kW. |
| Schedule NLL / VLL | New/very large loads; NLL $0.039328/kWh + $7.15/kW. |

Tacoma Power Data Access FAQ
Does Tacoma Power support Green Button data download for commercial accounts?▾
No. Despite full AMI deployment, Tacoma Power does not offer Green Button Download My Data or Connect My Data. C&I customers should use ENERGY STAR Portfolio Manager for automated monthly data sharing, or request interval exports from Customer Service at 253-502-8600.
How can a C&I customer get automated, ongoing usage data into a benchmarking or analytics platform?▾
Enroll the property in ENERGY STAR Portfolio Manager and complete the TPU MyConsumption intake form to receive a custom meter ID. TPU then uploads monthly consumption automatically. There is no general developer API.
Is there an EDI / trading-partner program for large accounts?▾
No formal EDI program is documented. Large customers and aggregators should contact the Business Solutions Office (253-502-8606) to discuss scheduled bulk exports or custom data arrangements.
Can a third-party energy consultant access my account data?▾
Yes, with your authorization. You can delegate MyAccount access or sign a written authorization so TPU releases a historical data package (typically within 5-10 business days). Washington law (RCW 19.29A) requires prior written consent before third-party access.
What interval granularity is actually available for analysis?▾
AMI meters read about 24 times per day, but the self-service portal exposes daily usage and trends rather than raw 15-minute or hourly exports. For granular interval data, submit a request to Customer Service or use ESPM for monthly benchmarking.
