Large Commercial & Industrial Demand Response Quick Start Program
Entergy Arkansas, Inc. Demand Response Program for Large
Commercial and Industrial Customers
Overview
The Large Commercial & Large Industrial Demand Response Program consists of
programs that encourage a change in energy use by a customer from normal
consumption patterns in response to changes in the price of energy over time.
The Arkansas Public Service Commission (APSC) has recognized Entergy Arkansas,
Inc.’s Optional Interruptible Service Rider (OISR), Large General Service
Time-of-Use Rate Schedule (GST) and Large Power Service Time-of-Use Rate
Schedule (PST) as Demand Response Program tools to help customers review their
current usage patterns and determine if they have opportunities to change
their consumption patterns.
Under OISR a customer that has 100 kW or more of load that they are willing to
interrupt at times of high electric system may benefit by contracting for a
portion of their load to be taken under OISR. Should they fail to interrupt
for any reason when an interruption is requested a penalty charge will be
assessed.
TOU rates may be beneficial for high-load-factor customers or customers that
can and will make changes in their process to utilize more demand and energy
during off-peak periods.
A detailed rate analysis is required to determine if any of these rate
schedules may be beneficial to a customer. It is important that the customer’s
Account Service Manager work with the customer and the Entergy Arkansas* Rate
Design and Administration group to develop such an analysis.
Who Qualifies?
The Optional Interruptible Service Rider (OISR) is available to
customers who have and are willing to interrupt a minimum of 100 kW every
month during on-peak hours. Customers must be willing to enter a contract for
at least a one-year period but not longer than a five-year period. Customers
must have the appropriate metering and communications equipment installed
prior to service being made available under this Rider.
The Time-Of-Use (TOU) rates, both the Large General Service Time-of-Use
(for customers with a maximum demand of less than 1,000 kW) and Large Power
Service Time-Of-Use (for customer with a maximum demand of 1,000 kW or
greater) are available to customers who can and will change their operations
to utilize demand and energy during off-peak periods. A Customer must remain
on the Time-of-Use rate for a minimum period of twelve (12) months.
How Does The Program Work?
Account Service Managers will share these rate options with customers. If a
customer expresses an interest in the Time-of-Use rate and/or the Optional
Interruptible Service Rider and would like to see if they would benefit by
these applications, the Account Service Manager will work with Rate Design and
Administration to develop a rate analysis. If the analysis shows that the
customer may benefit from one of these, then the Account Service Manager will
work with the customer to verify: (1) they understand how the new rate will
work, (2) the appropriate metering and communication equipment is installed or
will be installed before service is rendered under this tariff, and (3)
present and execute the appropriate contracts with the Customers.
Which Customers Receive Technical Assistance?
All customers that express an interest in this program and that qualify for
service under the OISR, GST or PST rate schedules will receive assistance from
the Account Service Manager in understanding the tariffs. The Account Service
Manager will receive internal assistance from the Rate Design and
Administration group in performing the rate analysis.
What Is The Cost Of The Program?
Costs will be identified through the tariffs and rate analysis. Additionally,
a customer may have to pay for the installation of non-standard metering and
communications equipment.
What Is The 2008 Goal For The Demand Response Program?
Entergy Arkansas’ goal is to sign up 3 MW of load and 1,160 MWH of energy
under the Demand Response Program in 2008 and an additional 3 MW and 1,160 MWH
in 2009.
