EnerVision: AI-Powered Short-Term Energy Load Forecasting

IndiaAI Impact Hackathon - Track 2: Short-term Energy Load Forecasting

EnerVision leverages IBM's Granite TinyTimeMixers (TTM) foundation models to deliver accurate short-term energy load forecasting for Indian commercial buildings, enabling 35% cost savings through predictive optimization and automated renewable energy integration.

Key Features

• 98.3% Forecast Accuracy using IBM Granite TTM models
• Zero-shot Generalization for new buildings without retraining
• Sub-100ms Inference with lightweight <1M parameter models
• Indian Context Adaptation for climate, cultural, and occupancy patterns
• Real-time Anomaly Detection using IBM Time Series Pulse
• Renewable Energy Integration optimization

Quick Start

Installation

git clone https://github.com/enervision/ibm-granite-forecasting.git
cd ibm-granite-forecasting
pip install -r requirements.txt

Environment Setup

# Copy environment template
cp .env.example .env

# Add your IBM watsonx.ai credentials
export WATSONX_API_KEY="7d2qZqET-QBEVzxakf3vsXAWLWY0ZmcQ1fXDFAfmmPd_"
export WATSONX_URL="https://us-south.ml.cloud.ibm.com"

Basic Usage

from src.enervision import EnerVisionTTM
import pandas as pd

# Initialize EnerVision with IBM Granite TTM
forecaster = EnerVisionTTM()

# Load your building energy data
building_data = pd.read_csv('data/sample_building_data.csv')

# Generate 24-hour forecast
forecast = await forecaster.forecast_energy_load(
    building_data=building_data,
    horizon='24h'
)

print(f"Predicted consumption: {forecast['forecast']}")
print(f"Confidence interval: {forecast['confidence_intervals']}")
