The Crust 1.0 Power Grid: Solar, RTG, Batteries & Night

Power Architecture: The Pulse of the Lunar Colony

Electrical energy is the foundational constraint of every lunar base in The Crust. On the Moon, solar energy is abundant during peak daytime hours but completely absent throughout the prolonged lunar night. An unmanaged power failure shuts down life support, freezes hydroponic crops, starves oxygen generators, and halts regolith refining.

Building a resilient power grid requires combining photovoltaic solar collectors, high-capacity underground battery buffers, automated load-shedding switches, and continuous generators (RTGs, Fuel Generators, and Fusion Reactors).

Generator Type	Output Rating	Operating Window	Input Requirements	Grid Role
Small Solar Panel	30 Power Units	Daylight Only	Clear line of sight to the sun	Starter power, local drill stations
Medium Solar Panel	75 Power Units	Daylight Only	Surface clear zone	Mid-game primary daytime power
Large Solar Panel	300 Power Units	Daylight Only	High crater rim placement	Heavy daytime industrial smelting
Fuel Generator	90 Power Units	Continuous (24/7)	Hydrogen & Oxygen gas	Nighttime buffer & emergency backup
RTG (Thermoelectric)	16 Power Units	Continuous (24/7)	Zero fuel (decay heat)	Isolated life support & deep radar
Fusion Reactor	600 Power Units	Continuous (24/7)	Helium-3 & Water	Late-game continuous baseload

Solid-State Battery Storage & Sizing Calculations

Because solar arrays produce zero electricity during lunar darkness, daylight surplus must be stored in high-density accumulator banks:

Battery Specifications and Technical Bounds

• Total Storage Capacity: Each standard Solid-State Battery module stores up to 100,000 units of energy.
• Discharge Rate Limit: Maximum instantaneous discharge is capped at 10 MW. If your base draws 25 MW of continuous power, you must construct at least 3 battery modules in parallel, regardless of total stored capacity, to satisfy the discharge rate.
• Recharge Rate Limit: Maximum recharge absorption is capped at 50 MW, allowing rapid recharging during bright morning solar peaks.

Sizing Equation for Overnight Energy Buffers

To prevent blackouts during solar gaps, calculate total required storage using base draw and discharge caps:

$$\text{Required Storage (units)} \geq \text{Continuous Load (MW)} \times \text{Duration (Cycles)} + \text{Reserve Buffer}$$

Adding a dedicated reserve buffer provides a vital safety cushion against unexpected dust storms, temporary solar panel shading, or increased life-support heater demands.

Solar Flare Events and Hotfix 1.0.9 EMP Immunity

One of the most dangerous environmental hazards in The Crust is the Solar Flare:

• Surface Equipment Vulnerability: Solar flares produce intense ionizing radiation and electromagnetic surges across the lunar surface. Prior to early patches, flares drained all battery banks and tripped circuit breakers across the entire map.
• The Hotfix 1.0.9 Subsurface Rework: In Hotfix 1.0.9, developer Point Motion updated event physics so that all batteries and accumulators constructed underground are completely immune to Solar Flare drainage.
• Architectural Directive: Never construct primary battery banks on the lunar surface. Always excavate subterranean battery vaults beneath the regolith to ensure stored life-support energy remains 100 percent shielded from solar storms.

Power Grid Segmentation & Automated Load Shedding

Do not wire your entire lunar base into a single unmanaged circuit. When battery reserves deplete during an extended night cycle, an unsegmented grid shuts down all buildings simultaneously. Instead, divide your electrical distribution into three distinct priority tiers using high-voltage switches:

Priority Bracket	Monitored Facilities	Emergency Power Source	Protocol During Low Battery
Tier Alpha (Life Support)	Electrolysis Plants, Oxygen Scrubbers, Water Recyclers, Medical Center	Underground RTG bank + Dedicated Battery	Protected: Never shed under any circumstances
Tier Beta (Logistics & Transit)	Conveyor Distributors, Expedition Centers, Freight Elevators	Fuel Generator backup circuit	Sustained: Maintained unless battery drops below 20%
Tier Gamma (Heavy Smelting)	Smelting Furnaces, Multi-Regolith Refineries, Concrete Mixers	Direct daytime solar feed	Shed Immediately: Disconnected automatically at sunset

By shedding Tier Gamma smelting furnaces the moment the sun dips below the crater horizon, your base conserves up to 70 percent of its stored battery capacity, guaranteeing that colonists survive the night in comfort.

Fuel Generators & the Helium-3 / Hydrogen Loop

When base energy demands exceed battery capacity, chemical and nuclear generators provide continuous power:

1. Fuel Generator Gas Logistics

The Fuel Generator produces 90 units of continuous power by combusting Hydrogen and Oxygen:

• Electrolysis Feed: Connect Electrolysis Plants directly to an Ice Melter. The resulting Hydrogen and Oxygen are piped into storage buffers.
• Large Gas Storage (Update 1.0.26): Utilize the Large Gas Storage module introduced in Update 1.0.26 to stockpile thousands of units of pressurized Hydrogen gas to fuel generator banks through long winter cycles.
• Gas Piping Safety (Hotfix 1.0.30): Following Hotfix 1.0.30, gas pipe supports cannot be placed on active transport roads, ensuring fuel pipelines do not obstruct logistics trucks.

2. Electric Pillar Upgrades (Update 1.0.12)

Power distribution across expansive lunar craters requires efficient wiring. In Update 1.0.12, research options were added allowing Electric Pillars to support up to 6 simultaneous connections with an expanded maximum radius, drastically reducing copper wiring costs and visual clutter across crater outposts.

Methodology & Data Verification: Power output metrics (Small Solar 30, Medium Solar 75, Large Solar 300, Fuel Gen 90, RTG 16, Fusion Reactor 600), battery limits (100k capacity, 10 MW discharge, 50 MW charge), and Solar Flare immunity rules are verified directly against official Point Motion release notes and Steam changelogs (Steam AppID 1465470).
