Methodology for Developing the Weighted Average
Rate for Wheeling Service

Methodology for Developing the Weighted Average Rate
for Wheeling Service

The weighted average rate payable for Wheeling over joint facilities at each Scheduling Point shall be calculated as follows:

WBAC	=	

Where:

WBAC	=	Weighted-average Wheeling Access Charge for each ISO Scheduling Point

Pn		=	The Wheeling Access Charge rate for a Participating TOn in $/kWh as set forth in Section 5 of the TO Tariff.

Qn		=	The Available Transfer Capacity (in MW), whether from transmission ownership or contractual entitlements, of each Participating TOn for each ISO Scheduling Point which has been placed within the ISO Controlled Grid.  Available Transfer Capacity shall not include capacity associated with Non-Converted Rights and Existing Rights of a Participating TO as defined in Section 2.4.4 of the ISO Tariff.

n		=	the number of Participating TOs from 1 to n
