Public Utility District No. 2 of Grant County Data Access FAQ
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.
