Power Guide: Generation, Storage & Grid Setup

Power in Dyson Sphere Program is how you run buildings, charge Icarus, defend your planet, and export energy between worlds; understanding generation, storage, transmission, and fuel tradeoffs is essential to a stable factory and late‑game Dyson engineering.

Generators — what options exist and when to use them

  • Wind Turbine: Early, fuel‑free, constant output scaled by a planet’s Wind Energy Ratio. Very efficient for cost vs power but requires spacing between units. Good for small outposts, early grid links, or large equatorial/polar farms. Output examples scale from 0 kW (no atmosphere) up to 480 kW or more on strong‑wind planets.
  • Solar Panel: Daylight‑only power that depends on the planet’s Solar Energy Ratio and latitude; panels can be tiled with no spacing penalty. Pair with Accumulators for overnight operation or place on polar/summer‑zone locations or continuous equatorial belts for steadier production.
  • Ray Receiver: Receives power from your Dyson Sphere/Swarm. In Energy mode it supplies 6–15 MW (scales with Continuous Receiving and upgrades) and can be boosted with Graviton Lenses and proliferation for much higher per‑unit throughput. It requires line of sight (unless mitigated by Planetary Ionosphere Utilization and lenses).
  • Thermal Power Station (coal/chemical burners): Midgame backbone. Burns many chemical fuels (Coal, Energetic Graphite, Hydrogen, Refined Oil, etc.). It is 80% efficient (only 80% of displayed fuel energy is extracted). Output per plant is fixed (2.16 MW max) and burn time depends on fuel energy; chaining plants with sorters is supported.
  • Mini Fusion Power Station: Burns Deuteron Fuel Rods for compact, high output: 15 MW per plant at full load; each Deuteron Fuel Rod burns for 40 seconds. Excellent for dense, reliable mid/late game power if you can supply Deuterium and Super‑Magnetic Rings.
  • Geothermal Power Station: Renewable placement‑restricted plant that must be built on lava or on a Core Driller crater from a destroyed Dark Fog base. Output varies with location; crater sites can give extremely high efficiencies (300%+), making them powerful early spikes or remote outpost power.
  • Artificial Star: Endgame generator that burns Antimatter Fuel Rods (or Strange Annihilation rods). Antimatter rods power an Artificial Star at 72 MW per rod (with different burn durations); Strange rods increase both energy and output. These are effectively converted Dyson energy and are a late‑game way to deploy huge compact power.
  • Other power sources: Plasma/combustible byproducts can be burned in Thermal Power Stations for byproduct disposal and temporary energy (useful to prevent line clogging).

Fuel choices and efficiency considerations

  • Thermal plants are versatile but have an inherent 20% loss; compute burn durations from fuel MJ × 0.8 ÷ 2.16 MW.
  • Crafted fuels can be worthwhile but include production energy overhead. Example: Energetic Graphite (from Coal) has higher energy density per unit and often yields net gain after smelting costs, but savings are small once smelter energy and sorter costs are counted; check your site’s throughput before committing.
  • Hydrogen Fuel Rods and Deuteron Fuel Rods scale well as high‑density fuels. Hydrogen Fuel Rods burn for 20 s in a Thermal Power Station; Deuteron Fuel Rods are for Mini Fusion Plants and burn 40 s at full load.
  • Refined Oil burns for 1.66 s in a Thermal Power Station (36 per minute) and can be profitably processed (e.g., X‑Ray Cracking / Plasma Refining) instead of burned directly.
  • Energetic Graphite is an efficient fuel alternative to raw coal and a common midgame choice.

Storage — Accumulators and Energy Exchangers

  • Accumulator (placed): stores 540 MJ, charges at up to 1.5 MW and discharges at up to 2.25 MW. Useful for smoothing night cycles, covering short spikes, and diagnostic monitoring of grid satisfaction.
  • Full Accumulator (item): charged accumulator kept in inventory; each stores 540 MJ, stackable and usable as Icarus fuel (discharges at a higher mech rate). Full Accumulators are also the transport unit for interplanetary energy.
  • Energy Exchanger: charges and discharges Accumulators (items) at 54 MW base (can be increased by proliferation up to 108 MW). Charge mode consumes only grid excess power; discharge mode provides priority supply at its rated output. Combine with Interstellar Logistics Stations to move Full Accumulators between planets (true interplanetary power transfer).
  • When using Energy Exchangers to export energy, ensure the charging planet has surplus generation (Energy Exchanger can draw the full 54 MW while charging and will slow if grid can’t supply it).

Transmission — towers and logistics

  • Tesla Tower: cheap, compact transmission tower with the second‑largest distribution area; no idle draw. Good for local distribution and densely packed factories.
  • Wireless Power Tower: longer range than Tesla but smaller distribution area and has idle power consumption (higher per‑unit cost). Can charge Icarus in range; stacking towers increases charge rate.
  • Satellite Substation: largest distribution area and very long connection range but relatively large idle consumption and cannot charge Icarus. Useful where few distributors are better than many small ones.
  • Signal Tower: longest connection range and can charge Icarus; it also has utility interactions with Dark Fog. Use for long remote links that require Icarus charging.
  • Planetary/Interstellar Logistics Stations: have charging behavior proportional to their stored energy deficit; when empty they can draw a lot of power while charging and therefore can stress weak grids. Interstellar Stations plus Energy Exchangers allow sending Full Accumulators to receive power on distant planets.

Grid management and practical tips

  • Always monitor grid Satisfaction (power supply ratio). If it drops below 100% buildings slow; below 10% some grids show OFF and stop operating. Accumulators make it easy to detect transient shortages via the Real‑Time Battery Data graph.
  • Use sorters of at least MK.II to feed Thermal Power Plants to avoid brownouts caused by sorter slowdown; sorter throughput/power scales such that moving an item costs the same overall energy across tiers, but MK.I can be a bottleneck.
  • Pair daytime renewables with accumulators sized to store enough energy for night demand: one accumulator charges at 1.5 MW (360 s to full). Each accumulator requires roughly 5 average solar panels (at 100% solar ratio) to charge at maximum rate; plan generation accordingly.
  • Ray Receivers: build and cluster to raise Continuous Receiving (it grows slowly when receivers are kept loaded); higher Continuous Receiving increases each receiver’s output. Receivers set to Photon mode consume large Dyson/Sphere power to generate Critical Photons (1.2 GJ per photon raw energy) and will scale sphere requests accordingly; photon mode multiplies receiver power request and can starve other receivers if the sphere is underprovisioned.
  • Planetary Shield Generators charge like accumulators and take priority over accumulators when charging; they consume significant idle/standby power and require substantial generation to maintain wide coverage. Be prepared to commit large infrastructure (or rely on high‑output sources like fusion, geothermal craters, or Dyson imports) before building many shields.
  • Geothermal craters from Dark Fog base destruction can yield extremely high output (300%+ efficiency) and are an effective early power spike—useful for defending new bases.
  • Exporting power via Solar Sails / Ray Receivers requires production and launch throughput matching sail lifetimes: Solar Sails have limited lifetime (default 5400 s) and must be produced/launched faster than they expire to grow a swarm. Solar Sail lifetime can be extended via research.
  • High‑tier facilities (Quantum Chemical Plant, Miniature Particle Collider) have steep power requirements; postpone or plan proliferation and additional generation before scaling these lines.

Scaling progression recommendations

  • Early game: Wind Turbines + a few Thermal Power Stations burning Coal or Energetic Graphite; use Tesla Towers for distribution.
  • Mid game: Add Solar Panels + Accumulators for clean day/night cycles; start Ray Receivers/solar sail operations as you approach Dyson development. Use Mini Fusion Plants if you can produce Deuteron Fuel Rods reliably.
  • Late game: Deploy Ray Receivers connected to a Dyson Sphere/Swarm for bulk power, use Energy Exchangers + Interstellar Logistics to move energy between systems, and transition to Artificial Stars/Antimatter rods or Strange rods for extremely dense, deployable power where needed.

Keep power margins generous — many advanced production lines and proliferator usage increase continuous demand significantly, and several buildings (Planetary Shield Generators, Logistics Stations while charging, Energy Exchangers charging) can create large temporary draws that destabilize an undersized grid. Plan fuel logistics, sorter throughput, and accumulator capacity together to maintain stable, uninterrupted operation.
