["Crimmins, Sean" <SCrimmins@caiso.com>]

Toby,

 

Here are examples of how the California ISO defines products (from our tariff available at http://www.caiso.com/27c3/27c3ead543ec0.pdf):

 

REGULATION

A Generating Unit offering Regulation must have the following operating characteristics and technical

capabilities:

(a) it must be capable of being controlled and monitored by the CAISO Energy

Management System (EMS) by means of the installation and use of a standard

CAISO direct communication and direct control system, a description of which

and criteria for any temporary exemption from which, the CAISO shall publish on

the CAISO Website;

(b) it must be capable of achieving at least the Ramp Rates (increase and decrease

in MW/minute) stated in its Bid for the full amount of Regulation capacity offered;

(c) the Regulation capacity offered must not exceed the maximum Ramp Rate

(MW/minute) of that unit times a value within a range from a minimum of ten (10)

minutes to a maximum of thirty (30) minutes, which value shall be specified by

the CAISO and published on the CAISO Website;

(d) the Generating Unit to CAISO Control Center telemetry must in a manner

meeting CAISO standards include indications of whether the Generating Unit is

on or off AGC at the Generating Unit terminal equipment;

(e) the Generating Unit must be capable of the full range of movement within the

amount of Regulation capability offered without manual Generating Unit operator

intervention of any kind; and

(f) each Participating Generator must ensure that the CAISO EMS control and

related SCADA equipment for its generating facility are operational throughout

the time period during which Regulation is required to be provided.

 

SPINNING RESERVE

Spinning Reserve and Non-Spinning Reserve. Each provider of Spinning

Reserve or Non-Spinning Reserve must be capable of receiving a Dispatch

Instruction within one (1) minute from the time the CAISO Control Center elects

to Dispatch the Spinning Reserve resource or Non-Spinning Reserve resource

and must ensure that its resource can be at the Dispatched operating level within

ten (10) minutes after issue of the Dispatch Instruction;

and

Spinning Reserve and Non-Spinning Reserve Capability. Each Generating Unit

or external import of a System Resource scheduled to provide Spinning Reserve

and each resource providing Non-Spinning Reserve must be capable of

converting the full capacity reserved to Energy production within ten (10) minutes

after the issue of the Dispatch Instruction by the CAISO, and of maintaining that

output or scheduled Interchange for at least two (2) hours.
