The high efficiency HVAC rate is available to commercial customers that meet one of the requirements below:
- Use either an air-source or ground-source heat pump as the only source of heating and cooling in their facility.
- Use an electric water heater (usually connected to a desuperheater on the heat pump) as the only source of water heating.
- Receive prior approval of the equipment from RPU. Note that equipment must be rated by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and meet the minimum efficiency standards listed below.
- Service under this rate must be separately metered from other facility loads.
General Service – High Efficiency HVAC
(Loads less than 75 kW)
Application
To commercial, industrial, governmental, and other types of General Service customers reconfiguring their current electric service, or adding a new service, to separately meter their high efficiency HVAC equipment. Not applicable to standby service.
Character Of Service
Single or three phase, 60 Hertz, alternating current at any one of the standard secondary service voltages as described in RPU's published Electric Service Rules and Regulations.
Power Supply Adjustment
Bills computed under this rate schedule are subject to adjustment in accordance with the Power Supply Adjustment (PSA).
Minimum Bill
$29.90 per month.
Payment
Payments are due on or before the due date.
Conditions Of Delivery
- Service under this rate is only for air source or ground source heat pumps and any other all-electric systems that meet the stated efficiency requirements as explained in the Availability subhead of this rate schedule.
- Service under this rate must be separately metered from other facility loads.
- Since the HVAC system must be separately metered for this rate, the customer is responsible for any rewiring and its associated costs.
- Service provided under this rate is subject to applicable provisions of RPU’s published Electric Service Rules and Regulations.
- Energy provided under this rate shall not be resold.
- RPU shall not be liable for any damage or loss sustained by the customer resulting from interruptions, deficiencies, or imperfections of service provided under this rate.
- Unless authorized by separate written agreement, standby electric generating equipment installed by the customer shall not be interconnected, or operated in parallel, with the RPU system. Customer shall own, install, operate, and maintain electrical interlocking equipment, which will prevent parallel operation, and such equipment shall be approved by RPU prior to installation.
Medium General Service – High Efficiency HVAC
(Loads where demand is at least 75 kW or more for three or more billing periods in a given calendar year, but less than 1,000 kW)
Application
To commercial, industrial, governmental, and other types of Medium General Service customers reconfiguring their current electric service, or adding a new service, to separately meter their high efficiency HVAC equipment. Not applicable to standby service.
Character Of Service
Single or three phase 60 Hertz, alternating current at any one of the standard secondary service voltages as described in RPU's published Electric Service Rules and Regulations.
power Supply Adjustment
Bills computed under this rate schedule are subject to adjustment in accordance with the Power Supply Adjustment (PSA).
Power Factor Adjustment
The customer agrees to maintain an average power factor of 0.95 or greater for the billing period and to prevent a leading power factor. If the customer's average power factor is less than 0.95 for the billing period, the billing demand will be determined by multiplying the measured demand by 0.95 and dividing the results by the customer's average power factor. The average power factor is defined to be the quotient obtained by dividing the kWh used during the month by the square root of the sum of the squares of the kWh used and the lagging reactive kilovoltampere-hours supplied during the same period. The customer's average power factor will be determined by means of permanently installed meters.
Primary Meter Discount
Customers approved for metering at 13.8 kV will receive a discount of 1.25% on base rate charges for measured demand and energy.
Transformer Ownership Credit
Customers owning transformers will receive a credit of $0.20 per kW on each month's measured demand.
Determination Of Demand
Measured demand is defined as the maximum rate at which energy is used for any period of fifteen consecutive minutes during the billing period. The billing demand shall be the greater of the measured demand for the billing period adjusted for power factor, or 75% of the maximum measured demand for the most current June-September billing periods adjusted for power factor (referred to as ratchet). Billing periods may not coincide with calendar months.
For an existing facility reconfiguring its current electric service to come under this rate by separately metering its high efficiency HVAC equipment, the ratchet will be removed from the current electric service. The ratchet will be effective beginning in October following the first separately metered high efficiency HVAC service during one of the summer billing periods, June-September.
At that time the ratchet will be reapplied to the current electric service and will be applied for the first time to the high-efficiency HVAC service.
Minimum Bill
The minimum bill shall not be less than the billing demand, as provided above, whether or not energy is used.
Payment
Payments are due on or before the due date.
