VPP managed-operations architecture connecting batteries, renewable energy, customer sites, and electricity markets through a cloud platform

Supported Battery Operating Models

Grid-scale battery storage facility

Grid-Scale Battery Storage

For grid-connected batteries from several megawatts to hundreds of megawatts, we combine balancing, capacity, and JEPX markets to maximize operating revenue.

  • Multi-use operations across balancing, capacity, and JEPX markets
  • A control platform that scales to hundreds of megawatts
  • 24/7 real-time monitoring and automated bidding
Battery storage colocated with a solar power facility

Renewable-Colocated Battery Storage

We optimize batteries colocated with solar generation to shift curtailed output and capture premium revenue under the FIP scheme.

  • Optimal control combining generation and market-price forecasts
  • Timing shifts for curtailed output
  • Maximized premium revenue under the FIP scheme

Behind-the-Meter Battery Storage (Industrial)

We make full use of batteries at factories, commercial facilities, and offices through peak shaving, self-consumption, and market participation.

  • Optimized electricity costs through contract-demand reduction
  • Hybrid operation combining self-consumption and market participation
  • Control logic that also accounts for business-continuity value
Residential battery storage installed at a home

Behind-the-Meter Battery Storage (Residential)

We optimize residential battery charging and discharging for solar self-consumption, lower electricity bills, and aggregated market participation, while retaining backup-power use during outages.

  • Self-consumption using surplus rooftop solar generation
  • Charging and discharging matched to tariffs and household consumption
  • Backup power during outages

Supported Markets

We explain each market product clearly and show the operating requirements for participation.

Battery storage responding quickly to power-system fluctuations in the balancing market

Balancing Market

We support available-volume calculation, bidding, control, and performance verification in line with balancing-product requirements.

  • Primary balancing serviceProvides a fast response to frequency fluctuations.
  • Secondary balancing service 1Tracks supply-demand fluctuations over several minutes to help stabilize the grid.
  • Secondary balancing service 2Responds to longer-duration dispatch signals to correct supply-demand imbalances.
  • Tertiary balancing service 1Secures the required volume from the day before through the operating day for area-wide balancing.
  • Tertiary balancing service 2Provides additional balancing capacity in response to same-day supply-demand changes.
Battery storage secured as future supply capacity in the capacity market

Capacity Market

We design operations around activation-order response and performance management.

  • Activation ordersManages available capacity and performance in response to capacity-market activation orders.
Battery electricity traded on JEPX in response to market prices

JEPX

We capture revenue opportunities through demand response and battery control based on market prices.

  • Market-price-based demand responseControls demand or batteries in response to JEPX prices and turns price spreads into revenue opportunities.
