Grid Dispatch Automation

Forecast the grid, dispatch the battery, hour by hour

Bluefield Energy predicts renewable output and price, then schedules storage charge and discharge for grids that run mostly on wind and solar. Fewer curtailed megawatts, steadier revenue.

The Problem

Solar ramps faster than operators can respond.

Western Japan's grid now carries enough solar capacity to flip from surplus to deficit in under 30 minutes during cloud events. OCCTO frequency rules leave no margin for delayed dispatch.

Operators who rely on manual scheduling or day-ahead-only forecasts are always a step behind. A battery that charges at the wrong time misses the imbalance signal and drains revenue.

Bluefield converts the same weather and SCADA data your grid already produces into a 24-to-48-hour ahead dispatch schedule that accounts for ramp risk, SoC constraints, and JEPX settlement windows.

How It Works

Three steps from sensor data to dispatch command.

Ingest

Pull NWP irradiance forecasts, SCADA generation readings, and JEPX imbalance price signals every 30 minutes.

Predict

A gradient-boosted ensemble model corrects for local cloud persistence and demand baseline shifts. Output: MW-by-hour solar generation curve for the next 24 to 48 hours.

Dispatch

The dispatch optimizer converts the generation forecast into a BESS charge-discharge schedule that respects SoC limits, ramp rate constraints, and market settlement windows.

Trust Signals

Built around western Japan's grid reality.

Osaka-based team with direct knowledge of OCCTO interconnection rules and western Japan solar generation patterns.

Integrates with JEPX day-ahead and intraday market price feeds for settlement-aware dispatch.

Designed for 50Hz grid operators - not a US-market tool retooled for Japan.

Integrations

Connects to the data your grid already produces.

Weather NWP, SCADA generation readings, JEPX market prices, and EMS dispatch targets - all in one forecast loop.

Operator Feedback

From the dispatch desk.

Managing a 50MW storage portfolio without automated dispatch meant operators were resetting schedules every shift. Bluefield's forecast-driven scheduling cut our manual adjustment cycle by roughly half in the first three months.

The 48-hour ahead BESS dispatch schedule integrates directly into our energy management system. It gives our trading desk visibility they did not have when relying on day-ahead market prices alone.
