Who We Are

The electrical grid is evolving faster than ever before. With the rapid growth of renewable energy, battery storage, electrification, and changing load patterns, utilities, developers, ISOs, and large energy users are facing increasingly complex operational and planning challenges. In this dynamic environment, accurate power system modeling has become essential for maintaining grid reliability, improving resiliency, and supporting confident decision-making.

We offer our consulting services dedicated to delivering advanced power system modeling services across major United States electrical power markets. Our mission is simple: help clients navigate the modern power landscape with technically sound, data-driven solutions that strengthen grid performance and support the future of energy.

We are here to support the evolving U.S. Power Grid

Power system studies are no longer optional — they are a critical part of ensuring safe, reliable, and resilient operations. We support organizations operating in major U.S. power markets and reliability regions, including PJM, ERCOT, CAISO, MISO, SPP, NYISO, ISO New England, WECC, ReliabilityFirst, and NERC compliance environments. 

By combining technical expertise with industry-standard simulation tools and market knowledge, we provide clients with actionable insights that help reduce risk, improve system performance, and streamline project execution. At Crest Grid, our mission is to deliver precise engineering solutions, powering reliable energy outcomes.

We offer a comprehensive range of power system modeling and engineering consulting services tailored to utilities, project developers, EPC firms, and IPPs.

Power Flow Studies

We provide detailed steady-state studies to evaluate voltage profiles, thermal loading, contingency conditions, and system performance under normal and stressed operating scenarios.

Dynamic Stability Studies

As inverter-based resources continue to expand across the grid, dynamic system performance has become increasingly important. Our transient and dynamic stability studies analyze how the power system responds to disturbances, including faults, generation trips, transmission outages, and frequency events.

Interconnection Support

Renewable developers face a complex and highly technical interconnection process. Our team provides modeling and engineering support for solar, wind, battery energy storage systems (BESS), and conventional generation projects throughout various ISO and utility interconnection processes. We assist with:

• Generator interconnection studies
• Model validation and benchmarking
• Compliance documentation
• Grid code assessments

NERC Compliance Support

North American Electric Reliability Corporation MOD and PRC compliance requirements focus on maintaining power system reliability through accurate system modeling, protection system performance, and disturbance monitoring. MOD standards ensure reliable planning and operational models, while PRC standards govern relay coordination, testing, maintenance, and event response to support grid stability, resiliency, and regulatory compliance. At Crest Grid, we assist with:

• NERC MOD-026-1 / 27-1, NERC MOD-026-2, NERC MOD-032-1
• PRC-019-2, PRC-024-3, PRC-025-2, PRC026-1, PRC-027-1, PRC-029-1

RMS and EMT Simulation Studies

RMS-type simulations are essential for assessing the dynamic performance of inverter-based resources (IBRs) in bulk electric systems, including frequency response, voltage stability, and transient stability over longer timeframes. They are computationally efficient and widely used for planning studies. However, RMS models cannot accurately capture fast electromagnetic transients, converter switching behavior, or control interactions. Our PSCAD-based EMT simulation services provide detailed high-speed analysis of system behavior during switching events, faults, converter interactions, and transient disturbances that cannot be fully captured through traditional RMS dynamic studies.

We support a wide range of studies, including:

• Renewable and BESS interconnection studies
• Grid-forming and grid-following inverter analysis
• Sub-synchronous interaction and oscillation studies
• Converter control validation
• Weak grid and low short-circuit ratio assessments
• Protection and control system performance evaluation
• NERC and ISO technical compliance support

Using PSCAD and EMT-type simulations, we help clients identify potential instability risks early in the project lifecycle while improving system reliability, resiliency, and operational confidence.

 Technical Excellence with Industry-Standard Tools

Modern electrical power systems require advanced simulation tools capable of analyzing everything from steady-state power flow conditions to high-speed electromagnetic transients. Each software platform serves a specialized role in helping utilities, developers, ISOs, consultants, and system operators maintain grid reliability, resiliency, and regulatory compliance. 

Our engineering services are supported by leading industry software platforms used throughout the North American power industry. Depending on project requirements, we work with tools such as:

• PSS®E
• PSCAD
• ETAP
• GE PSLF
• ASPEN OneLiner
• MATLAB
• Python-based automation tools

By leveraging advanced simulation capabilities and automated workflows, we provide accurate analyses while improving efficiency and turnaround times.
