Experimental Energy Reduction Program (EER)provides an economic incentive to qualified customers to release EAI
from its obligation to supply during periods of highly volatile market
prices, or when supply is severely constrained.
Completely voluntary EER features:

The program hours are from 2PM - 6 PM CDT, the 4 hour "super peak”.

The Customer must participate all 4 hours and at the same pledged demand
during each hour (minimum pledge is 150 kW).

Entergy’s posted price will be the same for all 4 hours.

Market Replacement Charges (penalties at a rate of 2X posted prices) apply to each kW that is
below 90% of the pledged demand, measured during each hourly interval.

There are Maximum Energy Reduction Payments of 130% of pledged demand. The customer
receives no further credit after surpassing 130% of their pledged energy reduction.
Participation:

No participation in 2005-2007

2003 Participation: 112 customers on EER, 37 MW
Market Value Energy Reduction (MVER) 
Completely voluntary, MVER’s criteria to participate
include:



Participants must deliver at least 1 MW of curtailable load at each participating
site*
Appropriate metering must be in place for monitoring and verification of hourly
load data
A customer may participate in MVER via:





Submitting a successful bid under MVCO, or
Signing an enabling agreement under MVE prior to daily bidding
The same load can not be served under another interruptible tariff and MVER
simultaneously
A customer can participate in both MVER programs, but the same load can not
be in both simultaneously
Participation:

No participation in 2005-2007
 2003 Participation: 31 customers on MVER, 136 MW
Under MVCO, sites that can provide  500 KW of curtailable load may aggregate within the same
jurisdiction as long as at least 1 MW total is provided. Under MVE, each site is treated independently and
must be able to deliver  1 MW of curtailable load.
