I'm writing a Subnautica Tracking/Information/Calculator Spreadsheet... and need help with energy numbers

[Bruj]

So I've spent the last 2-3 weeks solid working on a pet project of mine - a 14 sheet Spreadsheet (15 if you include the hidden "data" sheet for calculations). It includes everything from Biome, Flora, Fauna, Tool, Building, Vehicle, and even DataBase (PDA) entry information. I included a checklist with a % completion tool... and then I got really creative, and included a Vehicle Calculator that uses formulas and drop-down menus so you can pick which modules/arms/etc you want for each vehicle and it will give you both a material list as well as the raw material farming list of what you'll need. After that, it was only a hop skip and a jump before I started contemplating a full Base Building Calculator. One that will not only allow you to itemize all the parts you want and give you both the materials you'll need on-hand to build the whole base, the raw materials you'll need to farm... but ALSO calculate what your prospective Hull Integrity will be. It will even factor in the depth you built your base at. Or it will. Once I finish it. However... I then started thinking about Powering said base. What if what you planned will always be running at a deficit? .. So I started wondering how to set up a way of telling if your prospective base will be able to power itself, based on what type of power you're using and how many of said sources.

... Which ground to a skittering halt when I realized finding power consumption number data is excruciatingly hard. I've been able to find (or calculate) most of the power production places (including factoring in the average temperature that your Thermal plants are at).. and a good portion of the base parts that will drain the power. So far, I've found the floodlight, spotlight, battery and power cell chargers, fabricator, water filtration machine, fabricator and modification station... even the scanner room wasn't hard to find some numbers on for energy drain. Then I tried to find what power drain per minute a Moonpool that is actively charging a vehicle will use... and I ran immediately into a wall. The most I can find is that it's a vague number of "more than 150 energy" to charge a vehicle.... but nothing on the RATE that that 150+ energy is pulled from the pool of energy the base has available.

TLDR edition: I need to know how fast a Moonpool that is actively charging a vehicle will drain a bases' power. On a per minute scale. But I cannot seem to find this information anywhere. If you have this information, or any idea of where I can look to find it.... PLEASE let me know! I'm not sure what I'll do if I cannot find this information... because, obviously.. the energy part of the calculator won't work without the Moopool numbers. And yes, this is a serious question. I truly do have the spreadsheet in progress. To my calculations, I'm at just over halfway done with the whole thing. I've gotten a few pages completely done already - including the Vehicle Calculator (tested and working!!).

Oh, and final P.S. Yes, I will be publishing said spreadsheet when it's complete for anyone who wants it to use and refer to... So this information may eventually help lots of people! - and yes, it'll be completely free as it's just on Google Sheets. Feedback other than just the power numbers I'm missing is more than welcome, but don't feel bad if I don't take EVERYONE'S suggestions!

# Consumption.
Spotlight: 0.2 / second.
Floodlight: 0.2 / second.
Scanner room: 0.15 / second idle, 0.5 / second scanning.
Water filtration machine: 0.85 / second.
Battery charger: 0.0015 * capacity (100 or 500 per battery in charge) / second.
Powercell charger: 0.0025 * capacity (200 or 1000 per powercell in charge) / second.
Moonpool: 0.0025 * total capacity / second.
Fabricator: 5.0 / craft.
Seaglide: light 0.06 energy / second, moving 0.1 energy / second.
Flashlight: 0.125 energy / second when in use.


# Lava larva consumption.
Cyclops: 44 lava larva attach points.
Prawn Suit: 12 lava larva attach points.
Consume 0.05 energy per second.

# Power sources.
Solar panel is 1.25 energy per second in the best condition (close to the surface and not much water fog). Battery 75 power.
Bioreactor is 0.83 energy per second. Battery 500 power.
Nuclear reactor is 4.16 energy per second. Battery 2500 power.
Thermal plant is 1.65 energy per second at best (100°C). Battery 250 power.

Note that solar panels and thermal plants are difficult to calculate precisely.

The thermal plant depends on the day night scalar, the biome temperature, the depth, the day night depth multiplier, and some noise to add some variance. Some of them are curves.

The solar depends on the intensity of the caustic light of the biome, the day night scalar and of course the depth which is a curve as well.

@Ignis:

Is the lower consumption number on Battery and PC Chargers (100 and 200 / second respectively, apparently) a constant, idle drain by the charger when not loaded?

[admiral1018]

The battery and power cell chargers only drain energy when they're transferring power to the batteries or cells. When empty, or if the batteries/cells are full, there is no drain.

One normal battery will consume 0.0015 * 100 = 0.15 energy / second. One ion battery 0.0015 * 500 = 0.75.

If you have two batteries, it will be 0.0015 * 100 * 2 = 0.3 energy per second, and so on.

Same principle for the powercell charger.

Of course they don't drain anything when they don't have to charge.

So for instance you have a battery with 15%, you need 75% so the calculation is 75 / (0.0015 * 100) = 500 seconds to have a full battery.

If you have two batteries with 15% each, the calculation becomes 75 / (0.0015*200) = 250 seconds.

There is a difference when you decide to charge your Prawn Suit in a Cyclops / moonpool, as the calculation isn't the same as the powercell charger.

The moonpool / cyclops will always be the total capacity of the two powercells, it doesn't matter if one of them is fully charged.

Imagine you have two ion powercells. One is fully charged, the other is depleted.

You place both in the powercell charger:
0.0025 * 1000 = 2.5 energy / second to charge the powercell.

You do the same while they are in the Prawn Suit docked. Again one fully charged the second depleted:
0.0025 * 2000 = 5 energy / second to charge the powercell.

Oh! Nice. I'll add this link to my spreadsheet, since that's far less spoiler-y than my spreadsheet, and it's graphical.

SOOO Helpful, thank you!!

If anyone has anything else to add, I will be paying attention to this topic :)
