Applicable at the City's discretion in the territory served by the City of Grand Island at locations acceptable to the City, who meets all the following conditions for customers willing to take interruptible service under the provisions of this section.
A. Take three-phase service from the City's system at a nominal standard voltage of 13,800 volts or greater.
B. Requires 3,000 kW or more of fully interruptible demand. Any firm load must be separately metered and served under the otherwise-applicable rate schedule.
C. Enter into a service agreement with a term of 5 years, agreeing to pay a minimum contract demand rate, such service commencing no more than 18 months after Interruptible Service Rate Agreement (Contract) execution.
D. Customer's load characteristics will not have a detrimental effect on City. Detrimental effects will be determined at the City's sole discretion and may include, but are not limited to harmonics, sudden unexpected load or voltage fluctuations, an expected power factor of less than 90%, adverse impacts on other City infrastructure, a proposed load that is not consistent with City's planning and zoning regulations, and excessive financial risk to City.
E. The City determines that it has sufficient capacity available in production, distribution, and transmission facilities, at the location where service is requested, as it pertains to the current and future development plans of the City.
F. Has a monthly load factor of 60% or greater. This does not include the time when directed to curtail by the City.

Energy Charge: An Energy Charge will be assessed based on the number of kilowatt-hours consumed in any given hour multiplied by the cost of purchased energy from the Southwest Power Pool. The cost of purchased energy will be the higher of the day-ahead or real-time locational marginal price for the Grand Island load settlement location plus 0.0015 per kWh ($1.50 per MWh), unless City and customer agree to a price-sensitive day-ahead energy bid in which case, the energy charge for the price sensitive load will be based on the Day-Ahead locational marginal energy price at the Grand Island settlement location plus 0.0015 per kWh ($1.50 per MWh). In the event that energy is awarded via a price-sensitive load bid, but not utilized by the customer during the allotted usage window, the customer will be charged the difference between the Day-Ahead and Real-Time locational marginal energy prices, plus 0.0015 per kWh ($1.50 per MWh), for all unused energy.
In no instance shall any one (1) hour interval be assessed at less than $0.0015 per kWh ($1.50 per MWh), which will be the minimum assessed hourly rate calculated.
Deposit: Two (2) times the highest estimated monthly bill. Deposits held until Customer no longer takes service from the District.
Facility Charge: City may require a contribution in aid of construction based on actual cost of improvements necessary to provide interconnection to City's 13.8 kV or 115 kV system.
Minimum Charge: Customer Charge plus Interruptible Demand Charge multiplied by Contract Interruptible Demand plus Electric City Dividend.
Contract Interruptible Demand: To be eligible for the Interruptible Demand rate, the customer must demonstrate the ability to interrupt 100% of its Total Contract Demand with 30 minutes notice and execute a contract specifying the Contract Interruptible Demand. The City may interrupt service under any of the following conditions:
A. It is anticipated the City's demand in a given hour will be greater than the forecasted seasonal peak unless customer's service is interrupted. Winter and Summer Seasons peaks will be analyzed independently of each other.
B. The Southwest Power Pool declares an Energy Emergency Alert of any level.
C. The City experiences a facility outage or local system emergency affecting a facility that is directly necessary to serve the customer.
D. Up to an additional 60 hours per Contract Year, the City may interrupt service at its discretion for economic or operational reasons.
E. At the request of the customer, City and customer will coordinate to provide for a price- sensitive load bid to be submitted in the Day-Ahead market. A price-sensitive bid is one where the customer provides an upper limit on the hourly energy rate it is willing to pay. If the price threshold is exceeded, the customer agrees to interrupt service.
Customer must execute a service agreement specifying the amount of Interruptible Demand the customer will commit. The service agreement will include the amount of Interruptible Demand, methodology for measuring interruptible demand, testing protocols, notification provisions, and other information necessary to administer the interruption provisions of this rate schedule. Any non-interruptible load will be connected to a separate meter and billed based on the otherwise-applicable rate schedule.
To qualify for Interruptible Demand rate, the customer must demonstrate its ability to interrupt service through an annual test using protocols established in the service agreement. The test will be performed at a randomly selected on-peak time and will last up to four hours.
If customer fails to interrupt at any time requested by the City, the customer will be obligated to pay the Failure to Interrupt Charge for the current month and the number of prior billing months customer was served by City or eleven months, whichever is lower. Further, customer will be ineligible for the Interruptible Demand rate for a period of 5 years and will have their service converted to the otherwise applicable rate schedule.
