Rate Recommendations by Use Case
Commercial account up to 500 kW
General commercial loads take Rate 2, with a demand charge kicking in at 100 kW.
Rate 2 covers loads to 500 kW; near or above 200 kW, compare against Rate 7, which has a higher fixed charge but lower energy adders and a single $5.57/kW demand charge.
- Watch the 100 kW threshold where Rate 2 demand charges begin
- Compare Rate 2 vs Rate 7 if billing demand is consistently 200 kW+
- Request interval data from customer service to analyze peaks
Industrial plant (5-10 MW)
Mid-size industrial loads take Rate 14, where the 75%-of-peak minimum makes demand discipline critical.
Energy is cheap (~2.6 cents/kWh), so the $5.96/kW demand charge and the take-or-pay minimum (75% of prior-12-month peak) drive the bill. Food processors may qualify for Rate 16's slightly different adders.
- Avoid one-off demand spikes that set a 12-month minimum
- If you process/freeze food, confirm Rate 16 eligibility
- New large loads are routed to Rate 94 - verify classification
Large industrial load (>=10 MW)
The largest loads take Rate 15 (or Rate 94 for new large loads).
Rate 15 has the highest fixed charge ($1,061.08/mo) and larger energy adders, with a $6.03/kW demand charge and the same 75%-of-peak minimum; demand and contract management dominate cost.
- Confirm whether your load is a New Large Load (Rate 94) vs Rate 15
- Manage coincident peaks and contract demand carefully
- Engage Large Power Solutions (509-766-2517) for metering data
Energy consultants & data aggregators
Grant PUD has no automated data feed; plan for manual, customer-authorized data requests.
No Green Button, API, or EDI exists. Consultants must obtain written customer authorization and request data from customer service, accepting no SLA and a utility-determined format.
- Secure written customer authorization before contacting the utility
- Request specific meter IDs, data type, and date range
- Engage Large Power Solutions (509-766-2517) for C&I/interval data
Historical Rate Trends
Grant PUD's elected board approves annual rate adjustments to address inflation and, for larger classes, additional generation costs. The 2026 increases took effect April 1, 2026, with the largest increases hitting large-load classes (Rates 7-85). A 3% increase was applied for 2025.
April 1, 2026
2026 rate increases applied across classes; large-load classes saw the largest increases (Rate 7 +10.7%, Rate 14 +8.5%, Rate 15 +8.1%, Rate 16 +9.2%, Rate 19 +11.1%).
+8.1% to +11.1% (large loads)January 1, 2025
2025 budget approved with a 3% rate increase across classes.
+3%Overall trend: Steady, predictable annual increases; larger increases concentrated on large-load and industrial classes (Rate 7 +10.7%, Rate 14 +8.5%, Rate 15 +8.1%, Rate 16 +9.2% for 2026).
Next expected change: Next adjustment expected via the board's annual budget/rate process; monitor Grant PUD commission recaps for the following year's schedule.
Cost Optimization Strategies
With energy priced near $0.025/kWh, Grant PUD C&I bills are dominated by demand charges and (for industrial schedules) the 75%-of-peak take-or-pay minimum. The biggest levers are managing peak demand, right-sizing contract/billing demand, and selecting the correct schedule for the load size.
Peak demand management
For: Rate 2 (100 kW+), Rate 7, and industrial schedules
Flatten monthly billing-demand peaks to reduce the per-kW demand charge ($4.19-$9.95/kW depending on schedule). Request AMI/interval data from customer service to identify peaks.
Right-size billing demand (industrial minimums)
For: Rate 14, Rate 15, Rate 16 industrial accounts
On Rates 14/15/16 the monthly minimum is 75% of the highest billing demand over the prior 12 months. Avoiding a single anomalous peak prevents 12 months of elevated minimums.
Schedule selection by load size
For: All C&I accounts near schedule boundaries
Confirm the account is on the optimal schedule for its size (e.g., Rate 2 vs Rate 7 near the 200-500 kW boundary; Rate 14 vs 15 vs 16 by MW and use). Misclassification can raise basic/demand charges.
Dedicated EV metering (Rate 19)
For: Sites adding public/fleet DC fast charging
Meter DC fast-charging load separately under Rate 19 so it is billed at the EV schedule rather than blended into a higher general-service demand profile, but mind the $461.87/mo minimum.

Frequently Asked Questions
How does a commercial customer get usage or interval data from Grant PUD?▾
The ePay portal shows limited usage history. For interval or detailed AMI data, you must request it from Customer Service (509-766-2505) or, for large loads, Large Power Solutions (509-766-2517), providing the meter ID and date range. There is no Green Button download, API, or self-service interval export.
Can an energy consultant or aggregator access our data automatically?▾
No. Grant PUD has no API, Green Button Connect, or EDI. Consultants must obtain written customer authorization and submit a manual request to customer service; data is delivered case-by-case in a utility-determined format with no published SLA.
Why are Grant PUD's rates so low?▾
Grant PUD owns and operates the Priest Rapids Project (Priest Rapids and Wanapum dams), giving it low-cost hydroelectric power. Its PRP energy charge is about $0.02548/kWh, and residential rates average ~6.2 cents/kWh - among the lowest in the nation per the U.S. EIA.
Which rate schedule applies to an industrial load?▾
It depends on size: Rate 14 for 5-10 MW, Rate 15 for 10 MW and above, and Rate 16 for 5-15 MW food-processing plants. New large loads are served under Rate 94. Each industrial schedule has a take-or-pay minimum equal to 75% of the highest billing demand in the prior 12 months.
How can a C&I customer lower its Grant PUD bill?▾
Because energy is so cheap, focus on demand: flatten monthly peaks to reduce the per-kW demand charge, avoid anomalous spikes that set the 12-month industrial minimum, and confirm the account is on the optimal schedule for its size and use.
Can commercial customers choose a different electricity supplier?▾
No. Washington is a regulated, cost-of-service market with no retail choice. Grant PUD provides bundled service; rates are set by its publicly elected board of commissioners, not a state commission.
