Timberborn Power Systems Guide: Generation, Transmission, and Storage

Power is the lifeblood of any advanced Timberborn colony. Without a reliable power network, your beavers cannot operate critical production buildings, pump water during droughts, or run the late-game factories that keep a growing population fed and happy. This comprehensive guide covers every aspect of the power system, from your very first Power Wheel to sprawling networks of Water Wheels, faction-specific generators, Gravity Batteries, and the mechanical infrastructure that ties it all together. Whether you are playing Folktails or Iron Teeth, understanding power math, transmission efficiency, and storage strategies will determine whether your colony thrives or collapses during the next dry season.

Understanding Power Basics: Horsepower, Supply, and Demand

Power in Timberborn is measured in horsepower (hp). Every building that requires power lists its consumption in its detail panel, and every generator lists its current output. The fundamental rule is simple: your total power generation across a connected network must meet or exceed the total demand of all powered buildings on that network. If demand exceeds supply, buildings will flicker on and off unpredictably, drastically reducing your colony's productivity.

Power networks are formed by connecting generators and consumers through Power Shafts. Any building connected to the same shaft network shares the same power pool. This means a single Water Wheel generating 180 hp can power multiple small buildings simultaneously, as long as their combined demand stays under 180 hp. Conversely, if you connect too many consumers without enough generation, the entire network suffers. Planning your power budget before expanding production is essential, especially in mid-game when lumber mills, paper mills, and food processing buildings all compete for the same energy supply.

One critical concept is that power generation can be variable. Water Wheels depend on water flow, and Wind Turbines depend on wind speed. Only Power Wheels and Engines provide truly constant output (assuming they have a worker or fuel, respectively). This variability means you should always build more generation capacity than your theoretical minimum demand, particularly if you rely on water-based or wind-based power.

Power Wheel and Large Power Wheel: Beaver Muscle Power

The Power Wheel is the first power generator available to both factions and requires no research to unlock. It occupies a 1x1 footprint, costs only a few logs to build, and produces a base output of 50 hp when operated by a single beaver. The actual output scales with the beaver's movement speed, so beavers with higher well-being scores (which grant movement speed bonuses) will generate slightly more than 50 hp. Despite being the simplest generator, the Power Wheel remains useful throughout the game for powering isolated buildings or supplementing larger networks during peak demand.

The Large Power Wheel is an upgraded version that requires research to unlock. It has a larger footprint and requires two beaver operators instead of one, but it produces proportionally more power. The Large Power Wheel is particularly valuable in the early game when you need to power a Water Pump or Lumber Mill but have not yet built water infrastructure for Water Wheels. Keep in mind that every beaver assigned to a Power Wheel is a beaver not farming, building, or hauling, so you should transition away from muscle power as soon as your economy allows it.

A common early-game strategy is to place two or three Power Wheels near your first Water Pump. This ensures you can extract water even during a drought when river levels drop. As your colony grows and you unlock Water Wheels or faction-specific generators, you can gradually reassign these beavers to more productive work.

Water Wheels: Harnessing River Flow

Water Wheels are the backbone of most Timberborn power networks. They generate electricity from flowing water and require no beaver operators, making them essentially free power once constructed. The standard Water Wheel produces up to 180 hp at maximum flow, making it significantly more efficient than Power Wheels. However, their output depends entirely on the water current passing through them, which means placement is critical.

For optimal Water Wheel placement, you want to create channels that concentrate water flow. A narrow channel forces more water through a smaller area, increasing the current speed and therefore the power output. The ideal setup involves building dams or levees to funnel river water through a single-tile-wide channel with Water Wheels placed in sequence. Avoid placing Water Wheels in wide, open river sections where the flow disperses and each wheel receives less current.

The Compact Water Wheel is a smaller variant available to the Iron Teeth faction. It produces 60 hp per cubic meter per second of flow and fits into tighter spaces, making it useful for secondary channels or locations where a full-sized Water Wheel would not fit. The Large Water Wheel, also exclusive to Iron Teeth, is a significantly more powerful structure that generates substantially more power than the standard version, making it the preferred choice for Iron Teeth players once unlocked. Folktails do not have access to these variants but can compensate with Wind Turbines.

One important consideration: Water Wheels stop generating power when the river dries up during a drought. This makes them unreliable as your sole power source unless you have built reservoirs or dams to maintain water flow through dry periods. Pairing Water Wheels with dams that release stored water during droughts is a fundamental strategy for drought-proof power generation.

Wind Turbines: Folktails Exclusive Power

Wind Turbines (also known as Windmills) are exclusive to the Folktails faction and represent one of that faction's greatest advantages. Unlike Water Wheels, Wind Turbines do not depend on water flow, which means they continue generating power during droughts. This makes them an invaluable complement to Water Wheels for Folktails players. The standard Wind Turbine provides variable power output depending on wind conditions, producing anywhere from zero power during calm conditions to its maximum rated output during strong winds.

The Large Wind Turbine is the upgraded version, generating between 0 and 300 hp with an average output of approximately 144 hp. While this average is lower than a fully flowing Water Wheel, the key advantage is drought independence. During dry seasons when Water Wheels sit idle, Wind Turbines can keep critical infrastructure running. The wind in Timberborn follows predictable seasonal patterns, with certain times of year being windier than others. Experienced Folktails players learn to schedule power-intensive tasks during windy periods and conserve energy during calm spells.

Wind Turbines should be placed on high ground when possible. While elevation does not directly increase their output in the current game mechanics, building them on platforms or hills keeps them out of flood zones and frees up valuable ground-level space for other buildings. A cluster of four to six Large Wind Turbines can reliably power a mid-sized district throughout the year, including during droughts, giving Folktails a significant advantage in colony stability.

Engines and Geothermal Engines: Iron Teeth Industrial Power

The Engine is an Iron Teeth exclusive power generator that produces a consistent 200 hp as long as it is supplied with logs as fuel. Unlike Water Wheels, the Engine runs constantly regardless of water conditions, making it the Iron Teeth's answer to drought-proof power. The trade-off is that it consumes wood continuously, which means you need a robust logging and forestry operation to keep your Engines fed. A single Engine burns through logs at a steady rate, so plan your tree farms accordingly.

The economics of Engine power are straightforward: each Engine requires a dedicated supply chain of foresters planting trees, lumberjacks cutting them, and haulers delivering logs. While this represents a significant labor investment, the reliability of 200 hp of constant power is extremely valuable during droughts when your Water Wheels go offline. Many Iron Teeth players maintain a core of two to three Engines as their baseline power supply and use Water Wheels for additional capacity during wet seasons.

The Geothermal Engine represents Iron Teeth's most advanced power option. It harnesses underground thermal energy and is available only on maps that contain ruins with geothermal vents. When you can build one, the Geothermal Engine provides substantial power output without consuming any fuel, making it essentially free energy once constructed. However, the construction cost is significant, requiring advanced materials. Geothermal Engines are a late-game investment that can anchor an entire district's power grid.

Power Shaft Networks: Connecting Your Grid

Power Shafts are the transmission lines of Timberborn. They carry power from generators to consumers and come in several variants. The basic horizontal Power Shaft connects buildings on the same elevation level. Power Shaft Turns allow you to change direction at corners. These basic shafts cost minimal resources (typically logs and planks) and can be laid out quickly across your district.

Vertical Power Shafts are essential for multi-level colonies. They require 40 Science to unlock and cost more to build (2 Logs, 2 Planks, and 1 Gear per section), but they allow you to transmit power vertically. This is critical for connecting ground-level Water Wheels to elevated production buildings or for powering structures built on platforms above flood level. Without Vertical Power Shafts, you would need separate power generators on each elevation, which is wasteful and impractical.

Since the Update 7 overhaul, the power shaft system works similarly to the Tubeway system. You no longer need to delete existing shafts to add junctions for branching connections. This makes it much easier to expand and modify your power network as your colony grows. When planning your shaft layout, try to create a central trunk line from your main generator cluster and branch off to individual buildings or building clusters. This minimizes the total shaft length needed and makes troubleshooting easier when something goes wrong.

Keep in mind that buildings connect to the nearest shaft automatically if one is within range. You do not need to run a shaft directly to every building's door. However, you should verify the connection in the building's detail panel, as gaps in the shaft network will leave buildings unpowered even if they appear close to a shaft segment.

Gravity Batteries: Storing Power for Later

The Gravity Battery is the only power storage building in Timberborn, and it is one of the most important structures for managing variable power supplies. It works by using excess power to lift a heavy weight. When power demand exceeds supply, the weight descends and converts its potential energy back into power. Think of it as a mechanical capacitor that smooths out the peaks and valleys in your power generation.

Gravity Batteries are especially critical for colonies that rely on Wind Turbines or Water Wheels, since both sources fluctuate. During windy periods or high-flow times, your generators may produce more power than your buildings need. Without a Gravity Battery, that excess power is simply wasted. With one or more Gravity Batteries connected to your network, the surplus charges the battery, and the stored energy discharges automatically when generation dips below demand.

The capacity of a Gravity Battery determines how long it can sustain your colony during a power shortfall. A single battery might keep a small workshop running for several hours, but a large industrial district will drain it quickly. The general rule of thumb is to build one Gravity Battery for every three to four variable power generators in your network. This provides enough buffer to cover typical wind lulls or brief drops in water flow without causing brownouts.

For Iron Teeth players who rely primarily on Engines (which produce constant power), Gravity Batteries are less critical but still useful for managing the transition when an Engine runs out of fuel or when you need to temporarily power down a generator for maintenance. Folktails players should consider Gravity Batteries an essential part of their infrastructure from mid-game onward.

Clutches: Segmenting Your Power Network

A Clutch is a power transmission component that acts as a controllable switch in your shaft network. When engaged, a Clutch allows power to flow through it normally. When disengaged, it breaks the connection, splitting your network into two isolated segments. This gives you precise control over which parts of your colony receive power and when.

Clutches are invaluable for power management during resource-scarce periods. For example, you might have a secondary industrial district that only needs to run during certain seasons. By placing a Clutch between your main power grid and this district, you can disconnect it during droughts to ensure your core infrastructure (water pumps, food processing) receives full power. When the rains return and your Water Wheels spin back up, you re-engage the Clutch to bring the secondary district online.

In the automation update (Timberborn 1.0), Clutches become even more powerful because they can be connected to sensors and logic circuits. A Depth Sensor monitoring your reservoir level could automatically disengage a Clutch when water drops below a critical threshold, shutting down non-essential buildings to conserve power for water pumps. This kind of automated power management is a hallmark of advanced colony design and is covered in detail in our Automation Guide.

Power Math and Ratios: Planning Your Grid

Effective power planning requires understanding the consumption of common buildings. Most basic workshops consume between 50 and 100 hp. Water Pumps are among the most critical consumers, typically requiring 50 to 100 hp each. Lumber Mills, Paper Mills, and food processing buildings like the Grill or Bakery each demand their own share. Before expanding your production chain, always check the power requirements of new buildings and ensure your grid can handle the additional load.

Here are some useful planning ratios. One Power Wheel (50 hp) can sustain roughly one small workshop. One Water Wheel at full flow (180 hp) can power two to three medium buildings. One Engine (200 hp, Iron Teeth) can support a small cluster of three to four workshops. One Large Wind Turbine averages 144 hp, enough for two medium consumers on average, but you should account for calm periods by adding battery storage or backup generation.

A practical formula for colony planning: calculate your total demand, then build generation capacity equal to 130% to 150% of that demand if using variable sources (Water Wheels, Wind Turbines). If using constant sources (Power Wheels, Engines), 110% capacity is sufficient. The extra margin accounts for fluctuations, future expansion, and the occasional moment when all your buildings are running simultaneously at peak consumption.

Faction Power Strategies: Folktails vs Iron Teeth

Folktails players should prioritize Wind Turbines as their primary mid-game and late-game power source. The faction's access to both standard and Large Wind Turbines provides drought-proof power that requires no fuel or water flow. Supplement Wind Turbines with Water Wheels during wet seasons for maximum output, and use Gravity Batteries to buffer against calm periods. The Folktails power strategy emphasizes renewable, low-maintenance energy at the cost of some variability.

Iron Teeth players have a different toolkit. The Compact Water Wheel, Large Water Wheel, and Engine give Iron Teeth more options for raw power generation. The recommended strategy is to build Large Water Wheels along your primary river channels for baseline power during wet seasons, then rely on Engines fueled by a dedicated forestry operation for drought-proof power. The Geothermal Engine, when available, should be prioritized as a long-term investment that eliminates fuel costs entirely.

Iron Teeth's ability to stack buildings vertically also applies to their power infrastructure. You can build multi-level power generation complexes with Vertical Power Shafts connecting Water Wheels at river level to elevated production floors. This compact design is especially valuable on maps with limited flat space. The Deep Water Pump (available from game start for Iron Teeth, reaching 6 tiles deep) also means Iron Teeth can maintain water flow through deeper reservoirs, keeping Water Wheels active longer during droughts.

Advanced Power Tips and Common Mistakes

One of the most common mistakes new players make is building all their power infrastructure in one location. If a flood or contamination event damages that area, your entire colony loses power. Instead, distribute generators across multiple locations and connect them via shaft networks. This redundancy ensures that losing one generator cluster does not cripple your colony.

Another frequent error is neglecting power during colony expansion. It is tempting to build new production buildings first and worry about power later, but an unpowered building is worse than no building at all because it still costs resources and occupies space. Always expand your power grid before or simultaneously with new construction.

For Water Wheel optimization, experiment with channel width and dam height. A taller dam creates more water pressure, which increases flow speed through your channels. Some players achieve remarkable power output by building elaborate dam systems with narrow channels that maximize the flow speed past their Water Wheels. The investment in dam construction pays off in dramatically higher power generation.

Finally, remember to use the power overlay (accessible from the toolbar) to visualize your network. This shows you which buildings are connected, where power is flowing, and which areas might be disconnected. Regularly checking this overlay as you expand will help you catch problems before they cause production stoppages. With careful planning, a well-designed power grid will carry your colony from its humble beginnings to a thriving beaver metropolis.
