Description:

Abstract: This is a statewide layer of the electric transmission system at a scale of 1:24,000. Electric transmission lines are an interconnected group of lines and associated equipment for the movement or transfer of electric energy between points of supply and points at which it is transformed for delivery to customers or is delivered to other electric systems. While there is no uniform breakpoint on Federal Energy Regulatory Commission (FERC) Form No. 1 between transmission and distribution, it appears that utilities account for facilities operated at greater than 30 kV as transmission and that distribution facilities are usually less than 40 kV. Use the following seven criteria to define lines as distribution, as opposed to transmission: 1) Local distribution facilities are primarily radial in character. 2) Power flows into local distribution systems, it rarely, if ever, flows out. 3) When power enters a local distribution system, it is not reconsigned or transported on to some other market. 4) Power entering a local distribution system is consumed in a comparatively restricted geographical area. 5) Meters are based at the transmission/local distribution interface to measure flows into the local distribution system. 6) Local distribution systems will be of reduced voltage. This database is for transmission lines.

Purpose: This is an inventory of Kentucky's electric infrastructure, which will be used to: 1. Support the Kentucky State Board on Electric Generation and Transmission Siting; 2. Support the Public Service Commission by providing general reference information; 3. Support the Economic Development Cabinet's mission to attract new industry to the state; 4. Assist Kentucky state and local agencies and Federal Emergency Management Agency (FEMA) in emergency management, and 5. Replace the 1984 Electric Transmission Map of Kentucky published by Economic Development with a digital map. Further, this data will be used to: A. Enhance communication between and among utility companies and government agencies; B. Allow specific features to be located; C. Identify the operator of each feature, which is particularly critical in emergency situations; and D. Make a "smart" database so that the information that is already being collected by federal agencies can be identified and illustrated.

Use Constraints: This data is only available to public agencies when the data will be used to serve a legitimate governmental need or is necessary in the performance of a legitimate government function. The request must include a completed Open Records Request Form (http://psc.ky.gov/agencies/psc/forms/open_request.pdf) and an attached page with a statement of the legitimate government need and a Use Constraint Agreement with a signature and date.The signed Use Constraint Agreement reads: I understand that since September 11, 2001, location data of critical utility structures is considered sensitive information for reasons of homeland security. I will only use the information for the legitimate government function for which the information was requested and provided. I acknowledge that provision of the data, or maps made with the data, does not in itself create any rights to operate, adjust, modify, or otherwise interfere with the operation of any utility facility. Any of this data which provides location of underground facilities will never be used as a substitute for contacting a one-call center, such as 811, prior to excavation activities. I will not publish this data or maps made using this data on a World Wide Web site with public access. I agree to maintain a list of those persons that have been provided access to view detailed maps (scale of more than 1:500,000) of this information. I will include a statement on or with any map (digital or paper) made with the data to the effect that this data is considered sensitive information for reasons of homeland security and its distribution and use is restricted. I will include additional information on or with the map pertaining to restrictions and use as included in the Use Constraint Agreement. I will not redistribute this data to others, but shall refer requests by others for such information to the Kentucky Public Service Commission. I will give credit to the Kentucky Public Service Commission (PSC). I will abide by the following data disclaimer: All information within the product is believed accurate but is not guaranteed without error. While attempts have been made to ensure the correctness of the information presented, neither the Kentucky Public Service Commission nor any party involved in the creation and compilation of the data guarantees their accuracy, completeness, or suitability for a particular use. Any reliance on the information without independent verification from the applicable utility is entirely at the user’s own risk. Finally, I will take reasonable steps to safeguard the information against any use inconsistent with the Use Constraint Agreement and against any further disclosure or dissemination.
