Transmission System Analysis and Planning

OUR SOLUTIONS

EN Consulting offers a suite of comprehensive transmission system analysis
and planning services that analyze, identify, explain, and solve complex
technical issues for transmission owners. Our team of industry experts has
decades of former utility transmission network modeling and analysis
experience, including NERC reliability standards and audit support. Our
expansive team covers a range of services, from system-wide grid assessments
to interconnection study support.

We also assist our clients in navigating complex RTO policies affecting grid
planning. Whether it is traditional steady-state analysis for competitive
project development or investigating grid stability

under an array of system conditions, the EN Consulting team has the
expertise to perform robust and comprehensive system analysis on any portion
of a transmission grid.

TRANSMISSION ANALYSIS

Our range of capabilities includes:

• Steady-state power flow, stability, and short circuit model development
  and analysis using GE PSLF, Siemens PTI PSS®E, PowerGEM TARA, EMTP /
  PSCAD™, Aspen, etc.
• Interconnection analysis including system impact studies, point of
  injection screening, facilities studies, and capacity deliverability for:
  • Large generators and merchant transmission (HVAC and HVDC)
  • Renewables including solar (PV), wind turbines, etc
  • Energy storage and hybrid systems for capacity and ancillary services
    (frequency, voltage support, etc.)
• NERC Reliability Standard analysis support for all technical standards in
  all RRO regions, including WECC, MRO, Texas RE, SERC, RF, and NPCC
• CIP-014 analysis to determine facilities subject to specific physical
  security requirements
• Advanced reliability analyses covering a wide range of potential system
  conditions including retirements, high load growth, carbon reduction
  plans, renewables futures/portfolios, offshore wind, voltage and angular
  stability, frequency regulation, GMD, cost allocation analysis
  methodologies, etc.
• Transmission alternative solution analysis (i.e., upgrades or
  reinforcements) including budgetary cost estimates, non-transmission/
  wires alternatives analysis (NTA/NWA), storage solutions, dynamic reactive
  resources optimization studies, etc.
• Operational analysis including contingent outage/stranded load analysis
  (n-1 or n-1-1) as well as event/disturbance root cause analyses

TRANSMISSION PLANNING

Our capabilities in transmission planning include:

• Regional reliability analysis and planning support for every major
  RTO/ISO, including PJM, MISO, SPP, ISO-NE, NYISO, CAISO, and ERCOT
• System-wide or local area transmission assessments consistent with NERC
  TPL-001 or other regional/local planning criteria
• 5/10 year capital plans or corrective action plans to evaluate plan
  alternatives and reinforcement project ranking to establish final capital
  forecast and schedule
• Conceptual transmission project development services from feasibility and
  screening studies to cost estimating, scheduling, and owners engineering
  support
• Order 1000 competitive transmission solicitation analysis, project
  development, and formal bid application support
• ISO/Stakeholder committee advisement, analysis, and support
