This document details the Northern Indiana Public Service Company (NIPSCO) IURC Electric Service Tariff, Rate 643, for Station Power provided to Renewable Wholesale Generation Equipment.
TO WHOM AVAILABLE
This service is available to Renewable Wholesale Generation Equipment taking service at Transmission or Subtransmission voltage. The premises must be located adjacent to existing electric facilities with sufficient Transmission or Subtransmission capacity to meet the customer's requirements, subject to the conditions outlined in this Rate Schedule and the Company Rules.
CHARACTER OF SERVICE
This Rate Schedule applies to Station Power. NIPSCO will supply metered Transmission or Subtransmission service, utilizing available capacity from its electric supply lines. The service will be provided at the frequency, phase, regulation, and voltage specified in the Interconnection Agreement under the MISO OATT or PJM OATT. The customer is responsible for furnishing, installing, and maintaining all necessary equipment on their premises for transmitting, protecting, switching, transforming, converting, regulating, and utilizing the electric energy. This includes providing suitable buildings, structures, and foundations for housing and supporting any Company-supplied metering and protection equipment.
DETERMINATION OF AMOUNT OF ELECTRIC SERVICE SUPPLIED
The electric service supplied under this Rate Schedule is measured based on one of two options chosen by the customer in conjunction with their written agreement with NIPSCO. Customers may change their option election annually, with notification due by November 1st of the preceding year. If no notification is given, the previous year's election remains in effect. Service is measured using an Interval Data Recorder (IDR) meter installed by the Company.
OPTION A - NETTING
Under Option A, the Renewable Wholesale Generation Equipment Customer obtains Station Power by self-generating and netting this generation from the energy provided by NIPSCO. The hourly demand is zero if Net Energy Consumption is zero or negative. If Net Energy Consumption is positive, the hourly demand is positive. Billing Demand is the maximum hourly demand registered during the billing period.
Definitions for Option A:
- Energy Consumption: Station Power consumption in kWh over an Hourly Period, as measured by an IDR meter.
- Hourly Period: A clock hour interval from :00:00 to :59:59.
- Monthly Billing kWh: The aggregate Net Energy Consumption during a billing period.
- Net Energy Consumption: The difference between the customer's output in kWh and Station Power consumption in kWh over an Hourly Period. If output equals or exceeds consumption, Net Energy Consumption is zero (0). If consumption exceeds output, Net Energy Consumption is positive.
OPTION B - NO NETTING
Under Option B, the Renewable Wholesale Generation Equipment Customer obtains Station Power directly from NIPSCO without netting self-generation. The hourly demand is positive if the customer's Energy Consumption is positive during the hour. Billing Demand is the maximum hourly demand registered during the billing period.
