All packages include full access to core grid management features. Progress syncs across devices. Promotional codes valid for new operators. Training scenarios based on realistic grid operations.
Operators worldwide share strategies, compare shift grades, and master the art of frequency control together
Operators share shift reports, discuss risk flag patterns, and collaborate on optimal dispatch strategies. The community forum tracks seasonal best practices and maintains a library of high-performing commitment grids for peer learning.
The Winter scenario featured in version October 2026 release introduces unique demand patterns with morning peaks at 08:30 reaching 963 MW. Community operators compare approaches to managing the steep ramp from overnight lows of 619 MW.
Professional-grade simulation built on authentic grid operations principles
Grand Fruits delivers an authentic power grid management experience where every decision impacts four performance dimensions. The simulation models real-world electrical system dynamics including frequency response, reserve requirements, generation constraints, and environmental considerations.
Operators manage a diverse generation fleet spanning thermal baseload, combined-cycle gas, peaking capacity, and renewable hydro resources. Each asset type exhibits realistic operating characteristics including ramp rates, minimum run times, and efficiency curves that mirror actual power plant behavior.
The commitment grid interface visualizes resource scheduling across a 48-block timeline representing half-hour intervals throughout a complete shift. Color-coded blocks indicate resource type and commitment status, enabling rapid assessment of generation stack composition and identification of scheduling gaps or conflicts.
Comprehensive control suite for managing every aspect of grid operations
Maintain rock-solid 50.00 Hz system frequency through precise dispatch adjustments. Real-time imbalance meter displays MW deviation with color-coded severity indicators.
Analyze stacked area charts breaking down load by class. Track daily profiles from overnight minimums through morning peaks with detailed MW projections.
Commit generation assets across 48 blocks using intuitive Gantt-style grid. Each resource type displays distinct visual identity and operational constraints.
Track up to 134 operational flags spanning reserve adequacy, inertia levels, ramp capability, and constraint violations. Critical alerts demand immediate attention.
Balance operational expenses against reliability requirements. Post-shift hindsight analysis reveals opportunities for improved economic performance.
Earn composite score from A to F based on weighted performance across Cost, Reliability, Stability, and Carbon axes. Detailed breakdown highlights strengths and improvement areas.
