+# Energy Gradient Plugin
+
+Scores nodes based on energy gradients from `/egs/v1/gradient`.
+
+## Overview
+
+The EnergyGradient plugin enables energy-aware scheduling by scoring nodes based on their executable marginal energy capacity exposed via EGS (Energy-Gradient Signaling).
+
+## Node Configuration
+
+Annotate nodes with their EGS endpoint:
+
+```yaml
+apiVersion: v1
+kind: Node
+metadata:
+  name: node-1
+  annotations:
+    egs.ear-standard.org/endpoint: "http://egs-exporter:9100"
+```
+
+## Scoring
+
+```
+score = marginal_capacity_kw × (1 - cost_index) × (thermal_headroom_pct / 100)
+```
+
+Nodes with:
+- Higher `marginal_capacity_kw` (more available ΔkW)
+- Lower `instantaneous_cost_index` (cheaper)
+- Higher `thermal_headroom_pct` (more thermal margin)
+
+...receive higher scores and are preferred for scheduling.
+
+## Configuration
+
+Enable the plugin in the scheduler configuration:
+
+```yaml
+apiVersion: kubescheduler.config.k8s.io/v1
+kind: KubeSchedulerConfiguration
+profiles:
+  - schedulerName: default-scheduler
+    plugins:
+      score:
+        enabled:
+          - name: EnergyGradient
+```
+
+## Reference

+- EGS Exporter: https://github.com/oerc-s/egs-exporter
