(Continued)

INTERRUPTION COMPENSATION

Fixed Capacity Reduction Rate:

Large General Service Rates $0.0734 per kilowatt of reduction per event hour

Large Power Service Rates $0.0835 per kilowatt of reduction per event hour

DEFINITIONS

Actual kW Reduction. The kilowatt (kW) reduction during an Interruption Event, which is the
difference between a Participant’s hourly average kW measured at the Facility Site’s meter and the
corresponding hour of the Adjusted Baseline kW.

Adjusted Baseline kW. The Original Baseline kW plus or minus the “Day of” Load Adjustment
amount.

“Day of” Load Adjustment. The difference between the Original Baseline kW and the actual
metered kW during the hour prior to the Participant receiving notification of an event. Scalar values will
be calculated by dividing the Original Baseline kW for each Interruption Event hour by the Baseline kW
of the hour preceding the event notification time. The scalars are multiplied by the actual event day kW
for the hour preceding the event notification time to create the Adjusted Baseline kW from which load
reduction is measured. The Adjusted Baseline kW for each hour will be capped at 120% of the maximum
kW amount for any hour from the Highest Energy Use Days or the hours during the event day prior to
event notification.

Facility Site(s). All of a Participant’s facility or equipment that is metered from a single service
location that a Participant has taken service under Schedule 20.

Highest Energy Usage Days. The three days out of the immediate past 10 non-event Business
Days that have the highest sum total kW as measured across the Interruption Event daily parameters.

Interruption Compensation. The Actual kW Reduction for each hour multiplied by the Fixed
Capacity Reduction Rate. Participants are paid based on the average event kilowatt reduction.

Load Control Device. Refers to any technology, device, or system utilized under Schedule 20 to
enable the Company to initiate the Interruption Event.

Interruption Event. Refers to an event where the Company requests or calls for interruption of
specific loads with the use of one or more Load Control Devices.

Original Baseline kW. The arithmetic mean (average) kW of the Highest Energy Usage Days
during the Interruption Event daily parameters, calculated for each Facility Site for each hour.
