Rate Recommendations by Use Case
Mid-size commercial facility (office, retail, restaurant)
Facilities under 30,000 kWh/month and 100 kW take Schedule 20 (small/mid business) at 8.572 cents/kWh plus a $1.72/day base charge.
Below the 30,000 kWh / 100 kW thresholds there are no demand charges, so the simple energy-plus-base structure is most economical.
- Track monthly kWh and peak kW to confirm you stay under the thresholds
- Pull interval CSV from MySnoPUD to spot off-hours load
- Apply for commercial efficiency rebates
Large commercial / light industrial with demand over 100 kW
Loads over 30,000 kWh/month or 100 kW take Schedule 25 at 8.365 cents/kWh plus $4.85/day and a $7.21/kW demand charge on demand above 100 kW.
The added demand charge makes peak management the single biggest lever on the bill.
- Stagger large equipment startups to limit coincident peak
- Consider controls or battery storage for peak shaving
- Validate the $7.21/kW demand component on each bill
Very large industrial / campus over 5 MW
Customers over 5 MW that own their transformers take Schedule 36 at 6.862 cents/kWh plus $6.35/kW demand; New Large Single Loads move to Schedule 37.
The lowest energy rate is reserved for the largest, most efficient loads, but the $6.35/kW demand charge rewards high, steady load factor.
- Maintain a high load factor to dilute demand charges
- If expanding, model Schedule 37 New Large Single Load thresholds early
- Engage Business Services (425-783-1012) on interconnection and any custom terms

Overall 2.5% revenue adjustment for electric customers; small business energy charge increased from 8.37 to 8.572 cents/kWh (average small-business bill +$4.55/month).
+2.5%Overall trend: Gradual annual increases driven by power-purchase costs, capital investment (including the Connect Up AMI rollout) and operations; rates remain among the lowest nationally due to BPA hydropower.
Next expected change: Next adjustment expected in the 2027 budget cycle; monitor Board of Commissioners rate proceedings.
Cost Optimization Strategies
Because Snohomish PUD large-business rates carry meaningful demand ($/kW) charges, C&I cost control centers on managing peak demand and verifying correct rate classification, then leveraging the PUD's strong efficiency incentives.
Manage peak demand (kW)
For: Large Business (25) and Largest Business (36)
Schedule 25 adds $7.21/kW for demand over 100 kW and Schedule 36 charges $6.35/kW, so shaving coincident peaks via staging, controls or storage directly cuts the bill.
Confirm correct rate classification
For: All C&I customers
The 30,000 kWh/month and 100 kW thresholds determine whether you are on the small/mid or large schedule. Verify your classification annually as load changes; the greater-of formulas can penalize low load factor.
Use Strategic Energy Management & rebates
For: Commercial and industrial
SnoPUD offers commercial rebates, new-construction incentives and a Strategic Energy Management program that can lower consumption and demand.
Benchmark with ESPM + interval data
For: Commercial buildings subject to WA Clean Buildings
Link MySnoPUD to ENERGY STAR Portfolio Manager and pull 15-minute interval CSV to identify off-hours waste and demand spikes for Clean Buildings compliance.
To implement these strategies, you need your 15-minute interval data. Learn how to download Public Utility District No. 1 of Snohomish County interval data →
Frequently Asked Questions
How does a C&I energy manager get interval data for a client's Snohomish PUD account?▾
Have the account holder log into MySnoPUD, open User Profile, and grant your email Secondary User access with the Usage Data permission. Once you accept the email invitation and log in, you can download 15-minute interval data as CSV for the authorized period (30/60/90 days or custom).
Is there a public API for bulk or automated data pulls?▾
No. Snohomish County PUD does not offer a public REST API or formal aggregator program. Programmatic needs are met through customer-delegated Secondary User access, the Whole Building Profile, or an ENERGY STAR Portfolio Manager web-services link. For bulk needs, contact Business Services at 425-783-1012.
How do I get whole-building data for a multi-tenant commercial property?▾
Submit a Whole Building Profile request at my.snopud.com/WholeBuilding/RequestOwnerPermission with all service addresses and your professional credentials. After PUD review (5-10 business days) you can access combined monthly kWh and export it to CSV or ESPM.
Does Snohomish PUD support Green Button?▾
Not as a formally advertised program. The underlying MyMeter (VertexOne) platform is Green Button-capable, but the documented self-service path is CSV export from the portal. Confirm ESPI XML availability directly with the PUD before relying on it.
What rate schedule applies to my commercial or industrial facility?▾
Small and mid-size businesses (under 30,000 kWh/month and 100 kW or less) take the small/medium business schedule; larger loads over 30,000 kWh/month or 100 kW take the large business schedule with demand charges; customers over 5 MW that own their transformers take the largest-business schedule (Schedule 37). See the 2026 electric rate book for full terms.
