Development Roadmap

GridSim is actively developed. Here's what's done, what's in progress, and what's planned for future releases.

✅ Version 1.0 (Current Release)

The full initial release featuring all core gameplay systems, three campaign scenarios, and sandbox mode.

Game Systems

✓ Isometric field view with asset placement
✓ Transmission line routing with loading constraints
✓ Real-time power flow computation
✓ Grid frequency simulation (58–62 Hz)
✓ Load asset connection and routing (BFS pathfinding)
✓ Dynamic weather system (4 states)
✓ Line fault logic during storms
✓ Truck dispatch and routing for repairs

Assets & Infrastructure

✓ 7 generator types (solar, wind, coal, gas, hydro, nuclear, battery)
✓ 3 load types (town, business, industrial)
✓ Substation and cap bank grid devices
✓ Feeder and transmission line types
✓ Weather modifiers per asset (solar/wind affected by weather)
✓ Dispatchable vs. non-dispatchable distinction
✓ N-1 contingency analysis

UI & Controls

✓ Build toolbar with asset quick-selection
✓ Asset info panel (click any asset)
✓ Economy HUD (balance, net revenue/tick, tick count)
✓ Weather widget (current condition, forecast)
✓ Scenario progress panel (objective tracking)
✓ Pause and speed controls (1×/2×/4×)
✓ Keyboard shortcuts (P, F, S, 1–4, ESC)

SCADA Control Room

✓ Frequency monitor with ROCOF and ACE
✓ Frequency gauge (58–62 Hz with zone coloring)
✓ UFR/OFR relay status indicators
✓ Real-time load/gen chart (60-second history)
✓ Fuel mix breakdown by type
✓ Spinning reserve indicator
✓ Single-line diagram with live power flow
✓ Alert panel with timestamps

Economy & Persistence

✓ Tick-based revenue/expense system
✓ Asset build and sell mechanics
✓ Operating expenses per generator type
✓ Load revenue per tick (if served)
✓ Pollution index tracking (carbon intensity)
✓ Auto-save every 10 ticks to localStorage
✓ Save/load with scenario resumption

Audio & Gameplay

✓ Web Audio synthesized transformer hum
✓ Frequency alarm (pitch varies by severity)
✓ Fault sound (white noise crackle)
✓ Mute control button
✓ 3 campaign scenarios with objectives
✓ Sandbox free play with balance options
✓ Scenario complete/fail conditions
✓ Tutorial overlays and help system

Planned Enhancements

Q1 2026

Version 1.0 Launch

Core gameplay systems, 3 scenarios, sandbox, SCADA, audio, save/load.

Q2 2026

Advanced Voltage Model

Reactive power (MVAR) and voltage support. Capacitor banks gain real impact. Voltage instability can cause cascading failures. More strategic depth.

Reactive power flow computation
Voltage-dependent load modeling
Voltage collapse mechanics
Cap bank sizing and placement strategy

Q3 2026

Extended Weather & Hazards

More dynamic weather patterns, seasonal variations, and new hazard types.

Lightning strikes (random line damage)
Wind ramps (solar/wind ramping constraints)
Extended drought (reduced hydro output)
Seasonal demand curves (summer AC load, winter heating)
Transmission line sag limits (thermal constraints)

Q4 2026

Tutorial & QoL Features

Enhanced learning experience and quality-of-life improvements.

Interactive tutorial with guided objectives
In-game help and glossary system
Keyboard shortcut overlay (press ? to show)
Replay/replay history
Grid export to image (PNG/SVG)
Performance profiling overlay (FPS, tick time)

2027 Q1

Campaign Progression & Advanced Scenarios

Unlock system, additional campaigns, and hardcore difficulty modes.

Multi-scenario campaign unlock (v1.0 completes scenario 1 → unlock scenario 2, etc.)
Difficulty modes: Relaxed / Standard / Hard / Ironman
Leaderboards (fastest clear, longest uptime, lowest cost)
Community scenarios (steam workshop-style sharing)
Scenario editor (design and test custom grids)

2027 Q2+

Long-Term Vision

Ambitious expansions beyond the initial scope.

Multi-region grids: Connect separate regions via long-distance transmission
Cooperative play: 2–4 players manage different utilities, trade power
Modding API: Custom asset definitions, scenarios, mods
AR visualization: View your grid in augmented reality (if on mobile)
Educational mode: For utility trainee programs and universities
Procedural scenarios: AI-generated challenges with custom difficulty

Known Limitations

Simulation Simplifications

Frequency model: Simplified swing equation; real grids are more complex
Power flow: No AC load flow; we use simplified MW balance
Voltage: No reactive power component in v1.0
Transmission losses: Fixed 3% per line
Generator ramp rates: Simplified; not granular per unit

Scale & Performance

Grid size: 32×32 tiles; larger maps would need optimization
Asset count: Tested up to 100+ assets; performance degrades beyond
Network: No multiplayer; single-player only in v1.0
Mobile: Field view optimized for touch; some UI crowding on small screens

Content

Scenarios: 3 bundled campaigns; custom scenario editor planned
Localization: English only; translations pending community interest
Audio: No music track; audio is SFX-only for immersion
