Our services are intended for developers and owners who know from experience that engineering is not a commodity and understand the importance of saving time and money throughout the life of a project.

PPEs unrivaled expertise, large in-house team, high quality engineering and nationwide footprint allow our clients with large portfolios to trust that engineering work is done accurately and efficiently so they have minimal concerns about meeting the requirements of an AHJ’s codes or standards.

PSS®E Load Flow & Dynamic Modeling

Industry Standard for Load Flow and Interconnection Packages

• Best for: Utilities that require dynamic modeling of the project or system. Most ISO's in the eastern US and Hawaii require PSS®E for this analysis.
• Why it matters: PSS®E is the standard modeling platform required in most load flow and stability analyses during the interconnection process.
• Deliverables: .dyr dynamic file + supporting documentation
• Ideal for: Steady-state studies, load flow analysis, and dynamic response verification.

Reactive Power

Similar to load flow, this analysis specializes in maximum steady state AC current or AC power but with an emphasis on the phase relationship between voltage and current.

The reactive power study looks at the ability of the PV generation station to meet the utility requirements for power factor and voltage at the POI under varying utility voltage conditions. 

Cable Thermal Ampacity

Pure Power will perform an analysis of underground or overhead AC & DC circuits which analyzes the impact of the thermal environment on cable ampacity.

The information from this study is used to size the cables and design cable arrangements (a separate report version can be performed for DC circuits).

Grounding (Ground Grid)

We will perform a ground grid study of the grounding system to determine the ground potential rise, step and touch potentials on the site as well as the maximum step and touch potentials.

The ground grid system will be designed to reduce step and touch potentials below the maximum allowed values.
