Griffin Planner



Griffin Planner provides a unified environment for planning, scheduling, and optimizing network development and maintenance. It connects outage coordination, grid reinforcement, and connection of new assets such as renewable plants or charging infrastructure. By combining technical, operational, and investment perspectives, Griffin Planner helps TSOs and DSOs turn strategic goals into executable, data-driven plans.


Key Capabilities

Integrated Planning Environment

Combines grid development and maintenance planning in one collaborative interface.


Scenario-Based Simulation

Compares grid reinforcement, connection, and renewable integration options to support strategic decisions.


Power System Project Management

Tracks grid projects, maintenance tasks, and resource allocation to ensure efficient delivery.

DER and Flexibility Integration

Assesses the impact of new DER and flexibility connections while maintaining network stability.

Capacity and Performance Optimization

Analyzes network loading and upgrades to maximize asset use and ensure balanced performance

How It Works

Griffin Planner builds upon validated network data to create a consistent planning layer that represents both the current grid state and its future configurations.

Planners can simulate multiple development or maintenance scenarios and analyze their effects on system reliability, capacity, and flexibility. Each scenario can be compared side by side, providing a clear view of grid behavior, loading conditions, and overall system performance.

The system supports interactive collaboration across departments, allowing engineering, maintenance, and management teams to work within a single, browser-based environment. Workflows, approvals, and schedules are transparent, traceable, and accessible through Griffin’s unified interface.

Finally, Griffin Planner connects planned projects with operational data, ensuring that network development decisions reflect real-world constraints and support ongoing reliability.
