Federal Energy Regulatory Commission

[Docket No. AD12-10-000]

Reactive Power Resources; Supplemental Notice Requesting Comments

    On April 17, 2012, Federal Energy Regulatory Commission staff 
(Staff) held a technical conference to examine whether the Commission 
should reconsider or modify the reactive power provisions of Order No. 
661-A and examine what evidence could be developed under Order No. 661 
to support a request to apply reactive power requirements more broadly 
than to individual wind generators during the interconnection study 
    At the conference, discussion items included: The technical and 
economic characteristics of different types of

reactive power resources, including synchronous and asynchronous 
generation resources, transmission resources and energy storage 
resources; the design options for and cost of installing reactive power 
equipment at the time of interconnection as well as retrofitting a 
resource with reactive power equipment; other means by which reactive 
power is currently secured such as through self-supply; and how a 
technology that is capable of providing reactive power but may not be 
subject to the generation interconnection process (e.g., FACTs) would 
be analyzed. The staff and participants discussed information on 
methods used to determine the reactive power requirements for a 
transmission system and how system impact and system planning studies 
take into account changes in technologies connected to the system.
    Persons wishing to comment on these issues should submit written 
comments to the Commission no later than May 21, 2012.

    Dated: April 20, 2012.
Nathaniel J. Davis, Sr.,
Deputy Secretary.
