by CNXiaozhiy

EcoPower switches a Windows host's system power plan according to how many players are online on a Minecraft server.

What it does

The mod watches the online player count and selects a Windows power plan for each configured range, such as Power Saver when few players are connected and High Performance when the server is busy. Range boundaries are inclusive, and the plan GUIDs can be customized. Changes are announced to players through broadcast messages. Players are kept out of the count if their names carry bot suffixes or other prefixes matched by a regular expression, so fake players do not raise the load level. The plan GUIDs can be read from the output of powercfg list in Command Prompt.

Plans can also be switched by hand through commands, which is useful when the server is about to start a heavy task. Configuration files reload without a server restart, and a status view shows the current configuration in real time. Taken together, the mod is meant to reduce power use on a host during idle periods. EcoPower works with Windows only and needs no mod on the player side. Only the server needs it, and players join without installing anything. The code is published by CNXiaozhiy and is not open source; all rights are reserved, and the source and issue tracker are public.

Key features

  1. Player-count power plans

    Each configured player range maps to a Windows power plan, and the switch happens automatically as the count changes.

  2. Bot filtering

    Fake players matched by name prefixes or suffixes, such as bot tags, are excluded from the count using a regular expression.

  3. Manual plan switching

    Administrators can change the active power plan with commands, independent of the player count.

  4. Hot-reloadable configuration

    Config files take effect without restarting the server, and a live status view shows the current settings.

How it compares

Full comparison

Carpet Bot Limit is a Fabric server mod for 26.1.2 under the MIT License and is open source, so it targets a different version. DisKordel is open source under the GNU General Public License v3.0 only and covers 1.20.1 – 1.21.10, with a Discord bridge rather than power control. Server Discord Bot is open source under the MIT License for 26.2 and also handles Discord messaging. All of these are server-side only, like EcoPower, but none changes a system power plan.
