EEC is assisting the City of Loveland on a variety of projects including converting the existing distribution overhead line to underground, designing new circuits and providing support for interconnection requests.
EEC is providing engineering services to support the plant with their conformance to NERC reliability standards as well as analyzing and updating their protection systems and settings and coordinating with their transmission/substation group.
Multiple System Impact Studies (SIS) were performed for interconnections to the Highline Electric Association, Inc. 69kV system. Short Circuit, Power Flow and Dynamic analysis was performed using Aspen Oneliner and PSS/E to determine acceptability of the interconnection.
This project consisted of replacing an existing 4160V motor control center using across-the-line starters with a new Motortronics motor control center using reduced-voltage solid-state (RVSS) starters. The work was coordinated with plant outages and was executed with no additional delays to the outage schedule. Exponential Engineering performed the motor starting studies, created the drawing […]
EEC has designed a two mile 115kV transmission line with 12.5kV underbuild and 1.8 miles of 34.5kV subtransmission line with 12.5kV underbuild. Work included coordination with PG&E for the 12.5kV underbuild design and cutovers. Construction was through mountainous terrain south of Lake Tahoe. Civil/Structural design included foundations and steel transmission poles.
230kV Switching Station – the switching station is configured as breaker and a half bus containing six 230kV, 2,000A breakers and provisions for six future breakers, with four transmission line terminals and four additional future transmission line terminals.
230kV Transmission Line design consisted of 4 double circuit lines on self-supporting steel poles for the substation […]
