Rate Recommendations by Use Case
Demand-metered commercial customer
A demand-metered commercial site should confirm it is on the right Schedule 34 tier and prioritize peak-demand and power-factor management, since demand charges are a major cost driver above 30 kW.
Demand charges ($9.29/kW secondary; $9.02/kW primary) and power-factor penalties below 95% can dominate the bill; managing them yields direct savings.
- Correct power factor to 95%+ with capacitors
- Shift loads to cut the 15-minute peak
- Evaluate primary-voltage service (Sch 234) if eligible
Large industrial facility (>=1,500 kW)
Large industrials should take Schedule 85 at the highest practical voltage and use off-peak demand contracting and power-factor correction to minimize cost.
Transmission-level service cuts energy to 4.80 cents/kWh and demand to $6.27/kW versus 5.00 cents and $9.29/kW at secondary; off-peak demand is just 60 cents/kW.
- Pursue primary/transmission point-of-delivery
- Negotiate an off-peak demand contract
- Maintain power factor >=95%
Energy/sustainability manager needing data
For benchmarking and ESG reporting, set up the ENERGY STAR Portfolio Manager data exchange for automatic monthly consumption uploads, and enroll in SEM for ongoing analysis.
There is no public API or Green Button; Portfolio Manager is the structured third-party channel, and SEM/BuildingIQ add analysis.
- Submit the Consumption Request Form to pmdataexchange@clarkpud.com
- Allow ~10 business days for setup
- Note data is monthly, not interval, until AMI is deployed
Historical Rate Trends
As a public power utility, Clark Public Utilities resells power at cost with no markup; rate changes are adopted by the elected commission and tied to wholesale power and capital costs. Electric rates were raised effective March 1, 2024, and water rates changed January 1, 2026 (with a further change in 2027).
March 1, 2024
Electric rates increased effective March 1, 2024, reflecting higher wholesale power and system costs.
see commission filingJanuary 1, 2026
Water rates changed January 1, 2026 for all customer classes to support capital system improvements (with a further change in 2027). Electric energy is 8.79 cents/kWh.
see rate tablesOverall trend: Gradually rising with wholesale power and capital system costs; the commission adopted 2026 budgets for the electric and generating systems.
Next expected change: Water rates change again in 2027. Future electric adjustments are set by the elected commission; monitor commission meetings and press releases.
Cost Optimization Strategies
With no commodity to shop, Clark Public Utilities C&I customers optimize cost through rate-schedule and voltage selection, demand management, and power-factor correction, supported by the utility's energy-management programs.
Correct power factor to >=95%
For: Demand-metered commercial and industrial with motor loads
Billed demand is increased 1% for each 1% the average power factor is below 95% lagging. Adding capacitors to reach 95%+ avoids demand penalties.
Take service at higher voltage
For: Larger C&I able to own/operate primary equipment
Primary or transmission service carries lower energy and demand rates (e.g., Sch 85 transmission demand $6.27/kW vs. $9.29/kW secondary).
Manage peak demand
For: Demand-metered customers
Demand charges apply to all kW above 30 kW. Staggering equipment and load-shifting reduces the 15-minute peak that sets the demand charge.
Use off-peak demand contract
For: Larger C&I with shiftable off-peak load
For loads over 30 kW (or 1,500 kW on Sch 85), an off-peak demand option (60 cents/kW) is available by special contract for demand outside weekday peak hours.
Enroll in SEM / BuildingIQ
For: Commercial and industrial customers
Strategic Energy Management and BuildingIQ provide benchmarking, energy coaching, and incentives; typical first-year SEM savings of 3-5%.

Frequently Asked Questions
Can my business choose a different electricity supplier?▾
No. Clark Public Utilities is a customer-owned public utility district with no retail supplier choice. It provides bundled, cost-based electric service at rates set by its elected commission, reselling power at cost with no markup.
Can we get 15-minute interval electric data?▾
Not broadly yet. Demand for C&I billing is measured on a 15-minute basis, but customer-facing interval data is limited under the current AMR system. The My Meter Exchange (AMI) deployment will enable 15-minute interval access through the metering portal over the coming years.
How do we get usage data for benchmarking or a consultant?▾
Use the ENERGY STAR Portfolio Manager data exchange. The building owner submits a signed Consumption Request Form (naming any authorized consultant) to pmdataexchange@clarkpud.com; the utility then uploads monthly consumption and cost data automatically, and the owner can share the property with the consultant.
What drives our commercial electric bill the most?▾
For demand-metered accounts, the per-kW demand charge (applied to all kW above 30 kW) and power-factor penalties below 95% are major drivers, alongside the per-kWh energy charge. Taking service at higher voltage lowers both energy and demand rates.
Does Clark Public Utilities support EDI or a public API?▾
No. There is no EDI (no retail choice exists to require it) and no public developer API or Green Button. Structured third-party data flows through the Portfolio Manager data exchange; custom needs go through a Key Accounts Manager.
