Accumulators can be used to limit the need for power for some parts of your factory.
There are naturally 3 items, which are good candidates for that:
How does it work?
An accumulator has a lower delivery priority than any other power-using entity, this guarantees, that it receives only energy, when you have enough. At the same time it can deliver energy in another electric network. Both facts together works in this case as a regulated transformer and delivers only energy into other networks, if you are producing enough. Or in other words: in a power shortage, only the unimportant parts of your factory stop - not the whole factory.
This is fine if you want to guarantee that basic functions of your factory keep working (lasers, ammo production, very dependent on your priorities) no matter how much power usage you add.
This especially makes sense for radars - the radar explores new parts of the map, and consumes a large amount of energy. It makes sense to limit it, because when you are low on energy exploring is the least important thing.
In general this is a technique which works well only when you just researched accumulators and solar panels, but don't have enough resources to build big solar farms and accumulator farms.

When it is about storing energy for later there are two questions:
- Which technology level is needed?
- How much afford to built the structure up?
Dependent of the current technology-level this is a list of how you can store energy:
- Principle: Adding lots of pipes and use much more steam-engines as really needed. Pipes store some energy, of course very little, but much enough to handle short energy drops of some seconds. In every case the over-usage of your energy production might be easier visible, if clever planned.
- As soon as you have oil-tanks, you can store quite significant amounts of hot water in them. See this article.
- This techniques stretches the time you can burn coal for you energy need, but sooner or later you will switch to accumulators. See Solar Farming.
- Sooner or later you will also switch of the steam engines, when you don't need them.
- With small pumps you can control the flow of water. See below.
The Electric network info GUI can be accessed by left-clicking any electric pole nearby.
You can see only the info from the electric network where that pole is connected to! Unlike the production-info (press P) the electric network info is not globally measured, but by network.
- Consumption - What are the current consumption demands. This bar should always be full. Otherwise, it means your production is too low compared to the needed consumption.
- Production - What is the current production amount. This bar should never be full. Otherwise, it means you are at the limit of your power-production.
- Accumulator capacity - How much power is currently held inside of all your accumulators combined in joule. For quick understanding: 1J = 1W * 1sec, see also wikipedia:Joule
- Timespan - Set the time span for the graphs below
- Detailed Consumption - A list of consumers from highest power consumption to lowest. In the picture example, you can see that 2 oil refineries take the most power, at 431 kW.
- Detailed Production - A list of producers from highest power production to lowest. In the picture example, you can see that only 9 Steam engines produce all the electricity in the factory.
- Consumption Graph - Shows the consumption of the different parts of your factory over time. You can choose the timespan as detailed in #4 above.
- Production Graph - Shows the production of the different producers of your factory over time. You can choose the timespan as detailed in #4 above.
Note, that the timeframe influences the shown detailed production/consumption: the displayed watts is the summed up watts in the timeframe (in the graph below) divided by steps of that timeframe. This means you can see the consumption of radars, even if you mined them meanwhile.

Placing electric poles while shift is held down will place it without any connecting wires.
- Mainly about using different networks, networks connected with accus to limit power - todo -
There are some points, which can show you, what needs or can be changed in the liquid network:
- If your steam engines can keep up 510 W of output during heavy load (when electric poles display satisfaction below 100%), it is safe to add more engines.
- If an engine displays a temperature below 100 degrees, add more boilers.
- If you look into the engines and the available energy is below 100%, add boilers/pumps or add a new line to your power plant.
- If needed energy is much below the available energy, all is fine.
- There are also tricks to avoid using too much power. See Electric network.
