station
Provide testing required for commissioning one new
switchgear building, one new power transformer, and all
138kV relay and control for new the transformer in the
main control building

range CT's for EPS metering for Transformers 1 and 2
Test six new free-standing CT's, verify wiring (two sets of 3
CT's each)
$10,800
4 Denton West Replace carrier communications hardware that is no
longer supported by the manufacturer for two
345kV lines and complete end-to-end testing with
Oncor (TMPA project; reimbursable)
Replace two TC-10B and four TCF-10B units with UPLC's on
two line panels; completely test local facilities; complete
end-to-end testing with Oncor for the two 345kV
transmission lines
$28,000
5 Denton West Complete end-to-end testing of the RD Wells and Jim
Christal 138kV transmission lines for new panels and
new breakers installed in Denton West (TMPA
project; reimbursable)
Complete remote end testing for the RD Wells and Jim
Christal 138kV transmission lines
$15,500
6 Fort Worth Commission the revised relay panel for F-440 after
the panel has been upgraded by replacing a 311L
relay with a 411L (makes F-440 relaying consistent
with DME standard protection scheme; supports
Denton West panel replacements)
Complete F-440 411L relay upgrade with relay testing,
wiring confirmation, functional checks, and end-to-end
testing on the Denton West 138kV transmission line
$10,600
$245,900

O&M and Engineering Support:
11 Arco Reprogram the protective relay system to add
transfer trip to Circuit #1 on the Arco to Collin 138kV
transmission line and complete end-to-end testing
as requested by Oncor
Complete required end-to-end testing with Oncor
(required to verify functionality and to comply with NERC
standards for coordination between neighboring utilities)
$8,600
12 Multiple stations Provide assistance and relay testing for adjusting
transformer differential relay settings in seven
substations to eliminate power flow limitations on
multiple transmission lines
Assist with changing CT taps and relay settings for
transformer differential relaying in Woodrow, Kings Row,
McKinney, North Lakes, Pockrus, Industrial, and Cooper
Creek substations; verify relay performance; test relays
only if required
$55,000
13 Multiple stations Provide testing, technical, and field support for
urgent, emergency, operational, or other needs that
normally cannot be predicted
Provide relay testing and/or other technical assistance,
consultation, or field support for items such as: reviews
and adjustments after system events or protective system
misoperations; discovery of protective system problems;
relay setting changes; support of adjacent utility requests;
protective system component or SCADA RTU replacements
or setting changes; reviews after equipment failures;
implementation of changes required for system studies,
protection philosophy changes, new NERC or ERCOT
requirements, or discovery of protective system problems;
regulatory audits related to protective systems;
compliance related requirements; etc. (Example: Most
recent transmission system coordination study identified
changes needed in at least 227 relays, some of which will
require testing)
