PowerGridPlus cross-mod compatibility

Cross-mod compatibility findings for Power Grid Plus against the power-related Steam Workshop mods catalogued in Mods/PowerGridPlus/RESEARCH.md Appendix B / D, with the specific compat-flagged cases called out by the eighth verification task in Mods/PowerGridPlus/TODO.md.

This page covers two kinds of finding:

• Live-tested against game version 0.2.6228.27061 on DedicatedServer/ (the user's full enabled-mod set, fresh Mars2 world): MorePowerMod (3243132734) and PowerOverhaul (3579306377).
• Code-analytical for priority mods that are not subscribed in the developer's modconfig.xml: assessment based on the public information in Appendix B / D plus, for Re-Volt, direct reading of the source clone at .work/revolt-source/.

The eighth TODO bullet explicitly states "If a mod from the priority list is not enabled in the developer's modconfig, document the gap in the compat page and skip; do NOT install Workshop mods autonomously."

Test setup

Two server runs, both -Start -New Mars2 on the dedicated server with InspectorPlus Force Unpause Without Client = true:

1. Run A (with PGP): full user mod set including a freshly built Mods/PowerGridPlus/PowerGridPlus/bin/Release/PowerGridPlus.dll overlaid into DedicatedServer/data/mods/Local_PowerGridPlus/. Hash D034FEB497..., 91648 bytes, mtime 2026-05-22 03:20:32. World started at 03:55:56 game-clock.
2. Run B (without PGP): same mod set with the PGP DLL moved out of Local_PowerGridPlus/ (folder remains so StationeersLaunchPad still discovers it but loads no plugin). World started at 04:02 game-clock.

Both runs used the same set of currently-enabled mods from the developer's %USERPROFILE%\Documents\My Games\Stationeers\modconfig.xml (snapshot 2026-05-22): MorePowerMod, PowerOverhaul, Omni Transmitter Settings, BetterAdvancedTablet, JetpackHeightUnlocker, InspectorPlus, EquipmentPlus, PowerTransmitterPlus, plus a long tail of unrelated Workshop entries (~60 mods total). The dedicated server's mirror was sync'd at 03:05 by an earlier session.

Live test results

Power Grid Plus itself loads cleanly

Run A log markers:

03:55:38: loading the 'Power Grid Plus' mod
03:55:38: Power Grid Plus is patching recipe for ItemCableCoilSuperHeavy
03:55:38: successfully loaded the 'Power Grid Plus' mod

No [Error] / [Fatal] entries attributable to PGP. Harmony PatchAll succeeded; the CableCostPatches.ApplyRecipeCost() runtime override fired for the configured Super-Heavy Cable Cost Multiplier. PGP was loaded only from <DedicatedServer>/data/mods/Local_PowerGridPlus/PowerGridPlus.dll; the install/BepInEx/plugins/PowerGridPlus/PowerGridPlus.dll overlay (deployed earlier via -DeployMods) was NOT a second load — StationeersLaunchPad's LocalModSource owned the load and BepInEx's Chainloader silently deduplicated the install/plugins copy. Recommendation: prefer -SyncMods alone when testing cross-mod compat (per DedicatedServer/CLAUDE.md's duplicate-load guidance), and skip -DeployMods unless the user's modconfig entry points at a stale build.

MorePowerMod (3243132734) NRE on fresh-world spawn -- not PGP's fault

Both runs produced the same NRE within ~0 seconds of Started new game in world Mars2:

NullReferenceException: Object reference not set to an instance of an object
  at omnitransmitterlargemod.StationBatteryNuclear.PoweredChanged () [0x00043] in <a16d9ebb5ea44ed5b9bd11a5f4909f60>:0
  at omnitransmitterlargemod.StationBatteryNuclear.OnInteractableUpdated (Assets.Scripts.Objects.Interactable interactable) [0x00007] in <a16d9ebb5ea44ed5b9bd11a5f4909f60>:0
  at Assets.Scripts.Objects.Interactable.set_State (System.Int32 value) [0x0007f] in <0525d3f912224509836c1d7b1b652746>:0

  at Assets.Scripts.Objects.Electrical.Battery.WaitThenUpdateChargeDisplay () [0x00120] in <0525d3f912224509836c1d7b1b652746>:0

Assembly GUID a16d9ebb5ea44ed5b9bd11a5f4909f60 belongs to omnitransmitterlargemod.dll (MorePowerMod's internal assembly name; the file on disk is OmniTransmitterLargeMod.dll). The trigger path is vanilla Battery.WaitThenUpdateChargeDisplay -> Thing.set_Mode -> Interactable.set_State, which fires OnInteractableUpdated; the MorePowerMod-side StationBatteryNuclear.OnInteractableUpdated handler then invokes PoweredChanged, which dereferences a null field at IL offset 0x43.

Causation isolation: Run B (without PGP) reproduces the same NRE with identical call stack and identical IL offset. Therefore the NRE is a pre-existing MorePowerMod bug, independent of Power Grid Plus. PGP's StationaryBatteryPatches (which patches Battery.GetUsedPower, GetGeneratedPower, ReceivePower) is not on the call stack and does not influence whether WaitThenUpdateChargeDisplay fires nor whether the MorePowerMod handler succeeds.

Compat verdict for MorePowerMod: coexists with PGP at load time. The MorePowerMod NRE is a separate report worth filing with MorePowerMod's author. PGP need take no action.

Note on rate limits: per Appendix B, MorePowerMod's StationBatteryNuclear (230.4 MW capacity) and Nuclear Wireless Battery Cell (2.304 MW) subclass vanilla Battery, so PGP's MaxBatteryChargeRate=0.002 / MaxBatteryDischargeRate=0.007 apply automatically. The resulting numbers are 0.46 MW charge and 1.6 MW discharge per tick for the StationBatteryNuclear, and 4.6 kW charge / 16 kW discharge for the wireless cell. The wireless number is reasonable; the StationBatteryNuclear's 1.6 MW discharge-per-tick translates to a sustained ~80 MW load supported by one unit (50 tick/sec). That is intended by the mod's design ("nuclear battery for end-game megabases"), so the rate cap does not produce absurd values. Numbers were not directly snapshotted because fresh Mars2 has no spawned StationBatteryNuclear instances; InspectorPlus returned empty objects arrays for the battery types.

PowerOverhaul (3579306377) coexists cleanly

Run A log: no PowerOverhaul-attributed errors. PowerOverhaul patches PressureRegulator, BackPressureRegulator, VolumePump, and GasMixer for power-draw scaling, all in namespace Assets.Scripts.Objects.Pipes and unrelated to PGP's electrical-class patches (Battery, Transformer, AreaPowerControl, Device, Cable, CableNetwork, PowerTick). The two mods have no method overlap in their Harmony attribute target sets.

Compat verdict for PowerOverhaul: orthogonal. Coexists cleanly with PGP. Confirmed live.

Re-Volt (3587239682): code-analytical, must refuse-to-load

Re-Volt is subscribed on the developer's machine but currently disabled in modconfig.xml, so it was not loaded in either run. The compat assessment is code-analytical, against the Re-Volt source clone at .work/revolt-source/.

Patch-target overlap

Both mods inject their own PowerTick subclass into every CableNetwork.PowerTick field via Harmony constructor postfixes on CableNetwork, then patch PowerTick.Initialise / CalculateState / ApplyState with prefixes that short-circuit only when __instance is <ThisMod>Tick. The complete overlap table:

Target method	Re-Volt	PowerGridPlus
CableNetwork..ctor() postfix	inject RevoltTick	inject PowerGridTick
CableNetwork..ctor(Cable) postfix	inject RevoltTick	inject PowerGridTick
CableNetwork..ctor(long) postfix	inject RevoltTick	inject PowerGridTick
CableNetwork.DirtyPowerAndDataDeviceLists postfix	yes	yes
PowerTick.Initialise prefix	reroute to RevoltTick.Initialize_New	reroute to PowerGridTick.Initialize_New
PowerTick.CalculateState prefix	reroute to RevoltTick.CalculateState_New	reroute to PowerGridTick.CalculateState_New
PowerTick.ApplyState prefix	reroute to RevoltTick.ApplyState_New	reroute to PowerGridTick.ApplyState_New
PowerTick.CacheState reverse patch	yes	yes
PowerTick.CheckForRecursiveProviders reverse patch	yes	yes
Battery.GetUsedPower	postfix (Re-Volt) / prefix (PGP)	yes
Battery.GetGeneratedPower	postfix	prefix
Battery.ReceivePower prefix	yes	yes
Battery.get_IsOperable reverse patch	yes	yes
Battery.CanLogicRead prefix	yes	yes
Battery.GetLogicValue prefix	yes	yes
Transformer.GetGeneratedPower prefix	yes	yes
Transformer.GetUsedPower prefix	yes	yes
Transformer.ReceivePower prefix	yes	yes
AreaPowerControl.ReceivePower prefix	yes	yes
AreaPowerControl.GetUsedPower prefix	yes	yes (PGP also patches UsePower)
Device.AssessPower prefix	yes	yes
Device.SetPower reverse patch	yes	yes

Failure mode

Constructor postfixes both run on every CableNetwork allocation; the LAST one wins the PowerTick field assignment. Harmony's PatchAll iteration order between mods is not defined (depends on which assembly loads first under StationeersLaunchPad's load sequence), so the surviving subclass is non-deterministic across sessions.

After that, both mods' prefix patches on the same vanilla method run in some order:

• Re-Volt's prefix: if (__instance is not RevoltTick) return true; — falls through (calls original) when PowerGridTick won. Returns false (suppresses original) when RevoltTick won.
• PGP's prefix: if (!(__instance is PowerGridTick)) return true; — falls through when RevoltTick won, suppresses original when PowerGridTick won.

Net: only ONE of the two rewrites is active per network. The other mod's prefix is dead code. This is "graceful coexistence" in the sense that nothing throws; it is not behavioral coexistence — the user loses whichever mod's behavior the constructor injection order discarded, with no log signal.

For Battery.ReceivePower / Transformer.GetGeneratedPower etc., the conflict is worse: both prefixes run, both mutate the same private fields (_powerProvided, etc.), and the original is skipped if ANY prefix returns false. Both prefixes WILL run regardless of return value; the last-write-wins outcome is undefined.

Recommendation: detect and refuse-to-load

The TODO bullet lists three options:

1. Detect Re-Volt and refuse to load.
2. Patch RevoltTick instead.
3. Document as incompatible.

Recommend option 1. Option 2 is brittle (depends on Re-Volt's internal class names and field shapes, both of which can drift across Re-Volt versions). Option 3 leaves the user with undefined behavior and no log signal that anything is wrong.

A detection check in Plugin.OnPrefabsLoaded before Harmony.PatchAll() is one line:

if (BepInEx.Bootstrap.Chainloader.PluginInfos.ContainsKey("net.sukasa.revolt") /* verify GUID */)
{
    Logger.LogFatal("Power Grid Plus is incompatible with Re-Volt; both rewrite the vanilla PowerTick. Disable one. Power Grid Plus will NOT apply its patches.");
    return;
}

The exact plugin GUID for Re-Volt is not verified at the time of writing; before implementing, decompile E:\Steam\steamapps\workshop\content\544550\3587239682\*.dll for the [BepInPlugin] attribute on Re-Volt's plugin class (live decompile gates Rule 2 in Research/WORKFLOW.md).

Priority mods not currently subscribed

The remaining compat-flagged mods from the TODO are not subscribed in the developer's Workshop folder (E:\Steam\steamapps\workshop\content\544550\<id>/ absent). They could not be live-tested in this session. The assessments below are taken from Mods/PowerGridPlus/RESEARCH.md Appendix B and from public Workshop descriptions (no live decompilation done in this session).

Workshop ID	Mod	Status	Code-analytical assessment	Action
3555588082	MoreCables	not subscribed	Adds two cable types above vanilla (super-heavy 500 kW, super-conductor 1 MW). PGP's VoltageTier.IsAllowedOnTier switch only covers the vanilla three (normal / heavy / superHeavy). MoreCables' tiers fall through to the default arm, which (per VoltageTier.cs) treats them as their nearest vanilla peer — likely OK for super-conductor (treated as superHeavy) but the classification rule is unspecified. Open question in Mods/PowerGridPlus/RESEARCH.md §12.	Test when subscribed. Decide whether to classify them as superHeavy, reject, or expose a config string.
3470776044	CableTypeSwitcher	not subscribed	Adds a CABLETYPESWITCH console command that converts a whole CableNetwork between tiers at runtime, bypassing PGP's Cable.CanConstruct cursor reject. The reactive burn-on-flow in PowerGridTick.Initialize_New (mixed-tier detection) should still fire because the conversion mutates Cable.CableType and the next tick's rebuild sees the mismatch.	Test when subscribed. Verify the burn fires after a CABLETYPESWITCH conversion.
3287183705	EL Switche	not subscribed	Adds a logic-controlled "switch" that spawns / removes vanilla cables (normal + heavy) at runtime. The spawned cables go through Cable.OnRegistered, which triggers DirtyPowerAndDataDeviceLists, which triggers PGP's reactive mixed-tier detection on the next tick. Should be caught by the existing backstop.	Test when subscribed. Confirm the reactive burn fires on logic-spawned cables.
3575959825	Deadly Electricity	not subscribed	Per Appendix B, patches PowerTick / CableNetwork / generator classes to add efficiency-loss-as-heat and cable-spark-on-cut mechanics. Same kind of conflict as Re-Volt: rewrites the same vanilla tick path. Likely incompatible.	Test when subscribed. Likely action: detect and refuse-to-load, mirroring the Re-Volt detection.
3004087671	3.6 Megawatt Battery	not subscribed	XML stat edit; vanilla Nuclear Battery capacity raised to 3.6 MWh. Subclasses vanilla Battery, so inherits PGP's rate cap (3600 kJ * 0.002/tick = 7.2 kJ/tick charge, 25.2 kJ/tick discharge — small). Expected fine.	Spot-check when subscribed.
3007388410	EGC	not subscribed	XL Wireless Battery raised to 1170 kWh + new recipes. XL wireless inherits vanilla WirelessBattery; PGP does not rate-cap wireless cells. Expected orthogonal.	Spot-check when subscribed.
3706534108	Super XL Wireless Battery (EGC Edit)	not subscribed	Same family; raises capacity to 90 MWh. Same expected behaviour.	Spot-check when subscribed.
3355912171	BuffWirelessBatteries	not subscribed	XML stat edit on the small/large wireless cells (12 kJ -> 27 kJ, 72 kJ -> 216 kJ). Orthogonal.	Spot-check when subscribed.
1785747072	Mod: Jigawatt Battery	not subscribed	New 1.21 GW creative-scale battery, subclass of vanilla Battery. With PGP's MaxBatteryDischargeRate=0.007, that is ~8.5 MW per tick discharge sustained, i.e. ~424 MW continuous output at 50 tick/sec. The cap likely keeps the number "sane" in the sense of avoiding overflow, but a single such battery still powers a fleet of bases — that is the mod's intent. May want a per-mod special case or a config-driven absolute cap for very high PowerMaximum values; left as a future-design call.	Sanity-check when subscribed.
2359999429	RRI - Boost Da Powa	not subscribed	Upgraded battery cells via XML recipe + capacity tweak (200 kJ / 600 kJ / 4 MJ). Cells, not station batteries; PGP does not patch BatteryCell. Orthogonal.	Spot-check when subscribed.
3234916147	Better Power Mod	not subscribed	Solar / wind / Stirling / turbine buffs + battery-charger / APC / omni-transmitter raises. PGP does not patch generator output magnitudes; it patches network simulation. Expected orthogonal -- a buffed solar farm just lights more loads on the heavy-tier backbone.	Spot-check when subscribed.
3579306377	PowerOverhaul (gas devices)	enabled (live-tested above)	Orthogonal -- different class targets. Confirmed clean.	—
3491001740	Custom Power DeepMiner	not subscribed	Per-device draw tweak on the (combustion) deep miner only. Orthogonal.	Spot-check when subscribed.
3159841144	Super Structures Mod	not subscribed	Pressure / temp limit edits on turbine generators and reinforced windows; lets vanilla generators run harder. Orthogonal to the tick.	Spot-check when subscribed.
1669621266	2x Solar Power	not subscribed	Solar-irradiance constant edit. Orthogonal.	Spot-check when subscribed.
1475742702	Realistic Solar Constants	not subscribed	Solar-irradiance constant edit (opposite direction). Orthogonal.	Spot-check when subscribed.

The rest of Appendix B (recipe / content / economy / QoL mods, IC10 scripts) is expected fully orthogonal and is not enumerated here.

Recommendations for Power Grid Plus

1. Detect Re-Volt and refuse to load. This is the one concrete code change emerging from this compat pass. The detection lives in Plugin.OnPrefabsLoaded before Harmony.PatchAll(). The exact Re-Volt plugin GUID needs verifying via a one-time decompile (see "Recommendation: detect and refuse-to-load" above).
2. Same pattern likely applies to Deadly Electricity once it is subscribed and patches can be inspected. Apply the same detect-and-refuse pattern under a separate detection if the patch overlap is confirmed.
3. Document the rest as expected-orthogonal. Appendix B already covers the relationship per mod; this compat page is the live verification supplement.
4. MoreCables classification rule remains open. Until live-testable (mod subscribed), the rule should default to "treat unknown CableType enum values as superHeavy-equivalent" in VoltageTier.IsAllowedOnTier's switch default; that maximises compatibility (unknown tiers act as the unrestricted backbone) without needing per-mod opt-in.
5. Big-battery cap consideration. Jigawatt Battery's effective ~424 MW continuous output is within the float wattage range, but a Server - Batteries config like Absolute Maximum Battery Discharge Watts could cap it independently of PowerMaximum * MaxBatteryDischargeRate. Left as a future-design call.

Verification history

• 2026-05-22: page created as the eighth-verification-task result for Power Grid Plus. Live tests on DedicatedServer/ with fresh Mars2 worlds in game version 0.2.6228.27061. Two runs (with and without PGP) isolated the MorePowerMod StationBatteryNuclear.PoweredChanged NRE as a pre-existing MorePowerMod bug. Re-Volt assessment is code-analytical against .work/revolt-source/Assets/Scripts/Patches/*.cs (PowerTickPatches.cs, CableNetworkPatches.cs, StationaryBatteryPatches.cs, TransformerExploitPatch.cs, AreaPowerControllerPatches.cs, DevicePatches.cs, BatteryLogicPatch.cs). The remaining 15 priority mods could not be live-tested because they are not subscribed in the developer's modconfig.xml; their assessments are taken from Mods/PowerGridPlus/RESEARCH.md Appendix B and the public Workshop descriptions.

Open questions

• MoreCables tier classification. VoltageTier.IsAllowedOnTier's switch should be extended to cover MoreCables' two extra CableType enum values once the mod is subscribed and the enum values are visible. The default-to-superHeavy fallback is the recommended interim policy but has not been live-tested.
• Re-Volt plugin GUID. The recommended detection check needs the actual [BepInPlugin] GUID from Re-Volt's plugin class. Verification requires a decompile of E:\Steam\steamapps\workshop\content\544550\3587239682\*.dll, deferred until the detection is implemented.
• Deadly Electricity overlap detail. The claim that Deadly Electricity patches the same PowerTick path is taken from Appendix B's category note; a direct read of the mod's assembly is needed to confirm and to identify which exact methods overlap. Deferred until the mod is subscribed.
• Jigawatt Battery sanity cap. Whether to add a separate config-driven absolute cap on per-tick battery discharge is an open design call; not blocking.
