Microgrid · The optimization platform

The software that makes the economic decision. Every 15 minutes.

Stroem's optimization layer runs solar, battery and load as one system, and pools all your sites into a single portfolio.

How the platform thinks

Every signal in. One combined decision out.

Every quarter hour the platform recalculates the optimal plan for the next 24–48 hours. Spot prices, solar forecast, battery state of charge, tariffs and ancillary-service markets are weighed against each other, never one at a time.

Data streams in

  • Spot prices, hour by hour
  • Solar forecast for the site
  • Battery state of charge
  • Tariffs and capacity limits
  • Ancillary-service prices

The optimization layer

  • Recalculates every 15 minutes
  • Co-optimizes all four value streams
  • Respects the grid-connection limit
  • Always holds the reserve

Dispatch out

  • Battery: charge, discharge or hold
  • Solar: use behind the meter or sell
  • Bids to the TSO: FCR, aFRR, mFRR
  • Peak kept below the limit
The system and its value streams

One system. Four sources of value.

Solar self-consumption

Solar is used behind the meter, displacing expensive imports. Typically 85–95% self-consumption with a battery.

Spot arbitrage

The battery buys cheap and uses or sells expensive on the spot market, optimized across 96 daily intervals.

Ancillary services

The battery bids FCR, aFRR and mFRR to the TSO. Passive income with no operational disruption, typically the largest line.

Peak shaving

Power peaks are flattened, keeping capacity-based grid tariffs down. Built into the optimization.

Full value emerges when the streams are co-optimized. The dispatcher plays all four against each other in the same decision, never one at a time.
Across the portfolio

Every site. One virtual power plant.

The platform runs all sites as one combined plant. Aggregation opens the full aFRR and FCR markets with reliable delivery; one site covers when another is busy. And value per MW grows with every site added.

As a pure portfolio effect, on top of each plant's own revenue. Case: a Danish industrial group, two sites, 500 kWp solar and 1 MW / 4 MWh battery run as one plant.

Indicative index. The more sites in the portfolio, the better the economics for all of them.

Strategic future-proofing

Ready for electrification of production.

The optimization layer already controls every asset. Electric boilers, heat pumps and EVs plug in without rebuilding, and the battery keeps peak draw below the grid-connection limit, so electrification doesn't require a costly grid upgrade.

Free up grid capacity

Intelligent control creates headroom on the connection for new electric loads.

Battery as buffer

BESS smooths large, fluctuating loads so peaks don't overwhelm the connection.

Green electrons

Self-produced solar makes an electrified process low-emission from day one.

Scalable platform

New assets join the same optimization, without rebuilding.

With solar, battery and optimization the peak stays below the connection limit even as consumption grows. Electrification without a costly grid upgrade.
