Watt Consultants brings extensive expertise in supporting the safe and efficient integration of distributed energy resources (DERs), electric vehicles (EVs), and other large loads into utility distribution networks. Our services span technical analysis, regulatory alignment, and system optimization to ensure seamless and cost-effective interconnection.

DER & Load Interconnection Studies
WattC delivers end-to-end technical support for distributed energy resources (DERs) and large load interconnections—including solar, wind, BESS, hybrid systems, and EV charging hubs. We perform feasibility assessments, System Impact Studies (SIS), and CESIRs to evaluate grid impacts on voltage, thermal loading, protection, and short-circuit levels.
Hosting Capacity & Grid Planning
Our team conducts Hosting Capacity Analyses to identify circuits capable of supporting new generation or load additions. These insights help utilities and developers optimize siting decisions, streamline permitting, and reduce project screening uncertainty.
Non-Wires Alternatives & Grid Modernization
WattC supports evaluation and design of Non-Wires Alternatives (NWAs), including demand response, battery storage, and microgrids. We assess technical feasibility, cost-effectiveness, and reliability benefits compared to traditional infrastructure upgrades.
Volt-VAR Optimization & CVR
We design Conservation Voltage Reduction (CVR) and Volt-VAR Optimization (VVO) strategies using IVVC tools to improve system efficiency and voltage quality—especially on feeders with high DER penetration or load variability.
Protection & Automation Engineering
Watt Consultants provides advanced protection coordination studies and Distribution Automation (DA) support. We analyze and tune relays, fuses, and reclosers, and design smart switching schemes, FLISR functionality, and reconfiguration strategies to enhance system reliability and reduce outage durations.
Advanced Power System Analysis & Compliance
Our engineers perform specialized distribution studies—including short circuit, flicker, voltage stability, and risk assessments (e.g., LROV, ROI, TGFOV). We also provide detailed design and compliance reviews to ensure alignment with IEEE, utility, and regulatory standards, including interconnection cost allocation support.
Dynamic and Transient Stability Analysis
Our team utilizes PSS®E to assess the system’s dynamic response to disturbances. This includes:
- Calculating critical clearing times
- Detecting low-frequency oscillations
- Verifying damping performance
- Evaluating the behavior of protection and special protection schemes (SPS)
These studies help ensure system resilience and compliance under a wide range of operating scenarios.
Short-Circuit Analysis
Using Aspen OneLiner, we perform detailed fault current studies to evaluate:
- Fault contributions at critical buses
- Breaker interrupting capabilities
- The adequacy of protection system coordination
Our analysis ensures compliance with ISO/RTO criteria and informs system protection upgrades and equipment procurement decisions.
Transfer Limit Evaluation
We assess thermal, voltage, and stability-based transfer capabilities across key intra- and inter-area interfaces. These transfer limits support:
- Loss of Load Expectation (LOLE) analyses
- Operational planning
- System adequacy evaluations
- Infrastructure investment decisions
