Substations are essential to a stable power supply. For transmission and distribution systems, our team delivers electrical engineering services to support safe and uninterruptible service while helping you address aging infrastructure, enhance sustainability, and meet increasing energy demands.

Guided by a clear understanding of operational and regulatory priorities, our substation specialists focus on reliability, compliance, and long-term performance. We assist with new construction, system upgrades, and the integration of distributed energy resources—keeping projects moving forward with confidence.

Reliable transmission lines are essential to safely delivering electricity across the power grid. ISG delivers expertise tailored to utility standards, supporting every phase from scoping and engineering through construction and final documentation.

Our team provides field coordination and construction support to help minimize work stoppages and meet scheduled in-service dates. Ongoing engineering support for transmission line modeling strengthens data accuracy and overall system performance.

Utility systems depend on complex electrical equipment that must perform reliably for decades under increasing demand and changing system conditions. ISG helps utilities evaluate and manage critical power equipment across transmission, distribution, and generation networks to improve performance and extend asset life.

Our power team supports decision-making from equipment condition assessment and replacement planning to specification and integration. By aligning technical requirements with operational needs, we help utilities reduce risk, improve reliability, and modernize aging infrastructure without unnecessary system disruption.

Power generation assets play a critical role in maintaining a reliable and resilient energy supply. ISG supports the development, modernization, and integration of generation facilities and the infrastructure required to safely and efficiently deliver power to the grid.

Our team provides services from early planning through commissioning, with expertise in electrical systems, interconnection requirements, substations, and plant integration. By aligning generation assets with transmission and grid infrastructure, we help clients improve system performance, enhance reliability, and support long-term operational objectives.

Cities and their engineering staff are responsible for delivering safe, reliable power to the communities they serve every day. ISG partners with municipal electric utility providers to strengthen distribution systems through practical, performance-driven engineering solutions aligned with system demands and regulatory requirements.

Whether addressing immediate system needs or planning future improvements, we support the full lifecycle of electric distribution infrastructure. Our team brings expertise in protection systems and automation to enhance reliability, improve performance, and support confident, cost-effective decisions. Paired with ISG’s multidisciplinary municipal engineering services, we deliver integrated support.

From data center site selection and due diligence through utility coordination, substation and power distribution design, our professionals address to achieve speed to power while design, permitting, and procurement advance.

Our mission critical engineering team designs resilient distribution, thermal management and cooling, and water systems for continuous operation.

ISG supports design-assist, fast-track packages, and EPC support for power infrastructure, engineered release-by-release. We also provide data center commissioning, including readiness reviews, systems verification, and functional performance, turning an energized building into reliable operation.
