AVAILABILITY:
This schedule applies to Customers with electrical use above 5 annual average megawatts (aMWs), or as warranted by special circumstances, and is available throughout the District’ service area with the exception of the Stehekin area. Service under this Schedule will require a Contract between the Customer and the District prior to connection of Service that will address any special circumstances and conditions applicable to the Customer’s Energy needs.
The Customer is responsible for procuring, installing and maintaining all necessary wiring, transformers, switches, cut-outs and protection equipment beyond the Point of Delivery, with such service facilities and equipment being of a type and character acceptable to the District. The entire service installation, protection coordination and the balance of the load between phases is subject to approval by the District.
RATES, TERMS AND CONDITIONS:
Rates, terms and conditions will be negotiated between the Customer and District and included in a Contract. Such Contracts may include but are not limited to, at the District’s sole discretion, rates, terms, and conditions for the sale and delivery of energy and services including, but not limited to, load following, load shaping, imbalance, firming, reactive power, voltage control, environmental attributes and conservation requirements.
SPECIFIC CHARGES:
Such Contracts may incorporate one or more of the following charges by reference:
4.a Energy Capacity Charge. The energy capacity charge applies in all billings periods beginning with the first billing period in which Demand first exceeds 5000 kW. The charge is $4.38/kW of the positive difference, if any, of 90% of the Demand minus the average demand during the billing period (which is the total delivered Energy for the billing period divided by the number of hours in the billing period).
4.b Load Imbalance Charge. The load imbalance charge applies in all months after the billing period in which Demand first exceeds 5000 kW. The load imbalance charge applies only in hours in which hourly delivered Energy deviates from hourly forecasted load, forecasted in the Seven-Day Hourly Load Forecast, defined below, by more than the lesser of: (a) 5% of hourly forecasted load; or (b) 2000 kWh. In hours in which the load imbalance charge applies, that hour’s contribution to Energy billed under the Contract is deemed to be the hourly forecasted load, forecasted in the Seven-Day Hourly Load Forecast, and the load imbalance charge applies. For all other hours, that hour’s contribution to Energy billed under the Contract equals delivered Energy and the load imbalance charge does not apply. The load imbalance charge calculations is set forth below. If the Excess Energy Surcharge also applies to the Contract, the Load Imbalance Charge does not apply to Energy billed the Excess Energy Surcharge.
Starting with the first billing period in which Demand first exceeds 3000kW, by 5:00 p.m. Pacific Time on each business day, Customer must deliver to the District via email in spreadsheet format an hourly load forecast for the seven days that start two days after the day the forecast is delivered (“Seven-Day Hourly Load Forecast”). The most recent Seven-Day Hourly Load Forecast will be used when calculating the Load Imbalance Charge. In the event the District has not received a timely Seven-Day Hourly Load Forecast for a given day, the load for each hour of the unforecasted day will be deemed to be forecasted at 0 kW.
LOAD IMBALANCE CHARGE CALCULATION:
The load imbalance charge varies hourly based on delivered Energy (“Actual Load”), scheduled load and power index prices. “Scheduled Load” means the load forecasted by Customer in the Seven-Day Hourly Load Forecasts. In some instances, the load imbalance charge may be a credit.
If the Powerdex Index ceases to be published or is no longer representative of the District’s real-time purchases and sales, the District, in its reasonable discretion, may select a replacement source reflective of the District’s real-time purchases and sales.
The load imbalance charge shall be determined by the District for each clock hour period as follows:
- Determine Mid-Columbia Hourly Index price published by Powerdex for each applicable hour (“Powerdex Index” ($/kWh)).
- Calculate: Load Imbalance = Actual Load – Scheduled Load
- Calculate: Imbalance Deviation (%) = Load Imbalance / Scheduled Load
- Per the below tables, multiply applicable Load Imbalance (kWh) by the applicable Load Imbalance Price.
Applicable when the Powerdex Index is greater than or equal to $0.00/kWh:
|
Imbalance Deviation (%)
|
Load Imbalance (kWh)
|
Load Imbalance Price when Actual Load is less than Scheduled Load (District will credit Customer for imbalance energy) ($/kWh)*
|
Load Imbalance Price when Actual Load exceeds Scheduled Load (Customer will pay District for imbalance energy) ($/kWh)
|
|
If the absolute value is less than 5%
|
Not applicable
|
Hourly energy usage will be charged at contractual energy rates.
|
Hourly energy usage will be charged at contractual energy rates.
|
|
If the absolute value is greater than or equal to 5% and less than 25%
|
The absolute value of Actual Load minus Scheduled Load
|
85% of the Powerdex Index
|
115% of the Powerdex Index
|
|
If the absolute value is greater than or equal to 25%
|
The absolute value of Actual Load minus Scheduled Load
|
75% of the Powerdex Index
|
125% of the Powerdex Index
|
For any calendar day in which the District incurs spill at any of its hydroelectric projects and Actual Load is less than Scheduled Load, and the Load Imbalance price is positive for an hour, the Load Imbalance price shall be $0.00.
Applicable when the Powerdex Index is less than $0.00/kWh:
|
Imbalance Deviation (%)
|
Load Imbalance (kWh)
|
Load Imbalance Price when Actual Load is less than Scheduled Load (Customer will pay District for imbalance energy) ($/kWh)

A persistent deviation occurs if Customer engages in a pattern of providing hourly load forecasts that result in Imbalance Deviations that are consistently greater than 5% and in one direction and generally occur at specific times of day or days of the week. If the District, in its sole discretion, determines that the hourly load forecasts result in a persistent deviation, the District may impose a fee of up to the greater of $0.10/kWh ($100/MWh) or 150% of the Load Imbalance Price to all Load Imbalance quantities in all relevant hours.
Example Load Imbalance Calculations
Customer pays:
Mid-C Powerdex Index: $0.025/kWh
Actual Load: 5,000 kWh
Scheduled Load: 4,700 kWh
Imbalance Deviation: 6.3%
Load Imbalance Charge for extra energy: $0.025 X 115% X 300 kWh = $8.63
4700 kWh charged at applicable energy charge.
District credits:
Mid-C Powerdex Index: $0.025/kWh
Actual Load: 4,500 kWh
Scheduled Load: 4,700 kWh
Imbalance Deviation: 4.2% - less than 5% so does not apply
4700 kWh charged at applicable energy charge.
4.c Load Following Charge. The load following charge applies in all billing periods beginning with the billing period in which Demand first exceeds 5000 kW. The charge is $5.48 per kilowatt of monthly average load-following in excess of 10% of average demand provided in the billing period. The highest 1-minute demand minus the lowest 1-minute demand in each hour will establish the load-following kilowatt for that hour.
4.d Demand Exceedance Charge. In addition to all other rates and charges, in each billing period in which Demand exceeds the Customer’s maximum authorized demand, the excess Demand will be billed at 3 times the highest demand charge applicable under the Contract. This charge is in addition to, not exclusive of, the District’s rights to require additional protective measures, recover for damages sustained to the Electric Service Facilities, disconnect Service, terminate Contract, or take any other remedial action available to recover losses and prevent future exceedances.
4.e Excess Energy Surcharge. In addition to all other rates and charges, a surcharge of one (1) times the greater of the highest energy charge applicable under the Contract or the Mid-Columbia Hourly Index price published by Powerdex for each applicable hour will apply to all Energy used within an hour in excess of the Customer’s maximum authorized demand. Any surcharge is in addition to, not exclusive of, the District’s right to require additional protective measures, recover for damages sustained to the Electric System, disconnect Service, terminate this Contract, or take any other remedial action available to recover losses and prevent future exceedances.
