A regional utility serving 4M customers had a mean absolute percentage error (MAPE) of 8.2% on day-ahead demand forecasts. Over-forecasting led to $18M annually in unnecessary generation costs. Under-forecasting triggered expensive peaker plants and risked brownouts.

Forecasting relied on 10-year-old statistical models that couldn't account for growing solar penetration, EV charging patterns, and weather volatility. The 3-person forecasting team spent most of their time cleaning data and running manual model adjustments.

The utility needed AI-powered forecasting that could handle renewable variability and emerging load patterns.

The Solution

Agents that ingest weather, analyze load patterns, forecast demand, and advise on generation mix

Vijan.AI deployed 5 agents. The Weather Ingester pulls meteorological data from 12 weather stations and satellite feeds, including cloud cover for solar forecasting. The Load Historian analyzes consumption patterns by segment, incorporating EV charging profiles and DER generation. The Short-Term Forecaster predicts next-hour and next-day demand using ensemble models. The Long-Term Planner models seasonal trends and capacity planning scenarios. The Dispatch Advisor recommends optimal generation mix to grid operators based on demand forecast, fuel costs, and renewable availability.

Autonomous Agents

How each agent reasons, decides, and acts

Step 1 · Grid Optimization

Grid Optimization Agent

Real-Time Grid Balancing & Dispatch

Orchestrates generation, storage, and demand response to match load in real time, autonomously dispatching power plants, batteries, and curtailment programs to maintain frequency and voltage stability.

Input

Load forecasts, generation availability, renewable output, storage SOC, frequency

Output

Dispatch orders, frequency regulation commands, balancing authority reports

Calls SCADA for real-time grid frequency, voltage, and interconnection flows
Calls load forecast engine for next-hour and day-ahead demand predictions
Autonomous decision: ramp generation, discharge storage, or trigger demand response
Routes dispatch signals to Renewable, Demand Response, and Outage agents

Step 2 · Renewables

Renewable Forecaster

Solar & Wind Generation Forecasting

Predicts renewable output using weather models and historical performance, autonomously adjusting grid dispatch to accommodate variable generation and minimize curtailment.

Input

Weather forecasts, solar irradiance, wind speed, historical plant data

Output

Renewable generation forecasts, curtailment recommendations, ramp alerts

Calls weather API for cloud cover, wind speed, and irradiance predictions
Calls solar/wind performance models to estimate plant-level output
Autonomous decision: recommend curtailment, storage charging, or export
Routes forecasts back to Grid Optimizer for dispatch integration

Step 3 · Demand Response

Demand Response Orchestrator

Automated Demand Response Activation

Enrolls commercial and industrial customers in load-shedding programs, autonomously dispatching curtailment signals during peak events to reduce grid stress and avoid outages.

Input

Peak forecasts, enrolled participants, price signals, grid emergency alerts

Output

DR dispatch events, customer notifications, load reduction confirmations

Calls demand response platform for participant enrollment and availability
Calls price signal API to trigger economic DR during high wholesale prices
Autonomous decision: dispatch DR events, notify customers, or escalate to manual override
Routes load reduction confirmations back to Grid Optimizer

Step 4 · Outage Prediction

Outage Prediction Agent

Predictive Fault Detection & Outage Prevention

Analyzes sensor data from substations and transmission lines to detect fault signatures, autonomously isolating equipment and dispatching crews before failures cause widespread outages.

Input

Sensor telemetry, fault history, weather conditions, equipment age

Output

Fault alerts, isolation commands, crew dispatch orders, outage forecasts

Calls sensor network for voltage sags, harmonics, and temperature anomalies
Calls fault database to correlate patterns with historical outage events
Autonomous decision: isolate faulty equipment, dispatch crews, or pre-stage materials
Routes outage alerts back to Grid Optimizer and Asset Health Monitor

Step 5 · Asset Health

Asset Health Monitor

Transformer & Line Asset Health Management

Monitors transformer temperatures, line loading, and insulation conditions using IoT sensors, autonomously scheduling maintenance and replacements to prevent catastrophic failures.

Input

IoT sensor data, loading profiles, insulation test results, maintenance history

Output

Asset health scores, maintenance schedules, replacement recommendations

Calls IoT sensors for transformer oil temperature, gas analysis, and load levels
Calls maintenance database to retrieve last inspection dates and condition reports
Autonomous decision: schedule preventive maintenance, defer replacement, or expedite repairs
Routes asset health insights back to Grid Optimizer for capacity planning
