RLC SERVICES

Avangrid (CMP)
Maine Power Reliability Program
RLC provided system planning and engineering studies – including
report writing and presentation before ISO-New England, Maine
Public Utilities Commission and other regulatory stakeholders
– for more than 550 miles of preliminary, alternate and selected
transmission line routes. We assisted in the preparation of the permit
applications for the Maine Department of Environmental Protection
as well as other local and state permitting bodies. RLC also played
a significant role in the construction sequence and planning for the
MPRP proposed substation and transmission improvements.
RLC has performed numerous analyses of MPRP’s potential impact
on existing CMP substation facilities, including these studies:
 teady State Impacts on existing station equipment bus, breaker
S
and switch configurations;

F
 ault Current Impacts on circuit breaker duty ratings, circuit
breaker transient recovery voltage (TRV), bus support insulators,
disconnect switches, grounding switches, line traps, capacitor
banks, and shunt capacitors;
S
 ystem Impacts on protection relays, shunt capacitor settings,
line relay applications, SPS systems, series capacitor, ground relay
polarization and out-of-step stability.
Eversource Energy
New England East West Solution
RLC provided reliability assessment of steady state and stability
performance, including report writing and presentation before ISO-
New England on the NEEWS Projects. We prepared the study reports
and played a significant role in the I.3.9 review and approval process
with the Transmission and Stability Task Force Groups.
