Platform · BK EMS
BK EMS monitors, optimises and controls the battery, solar PV, grid and consumption in real time. We develop and operate it ourselves: no third-party dependency.
Architecture
The EMS Local runs the plant. The Operations EMS oversees all plants at once and decides based on the market. Both integrate BMS, inverters, meters and sensors.
On siteRuns on site, next to the battery, with local control. Sees every device and every cell.
CentralisedFrom the control centre it manages several plants at once, schedules hour by hour and decides based on the market price.
Local and remote control. Over-the-air (OTA) software updates, with no site visits.

01 · Overview
State of charge, battery power, PV generation, consumption, OMIE price and tariff period in real time. The diagram draws the flows between grid, PV, battery and load, with one node per active device.
Real screenshots of BK EMS running on a demonstration plant with simulated data.
Capabilities
Control algorithms, continuous monitoring and communication with BMS, inverters and auxiliaries. For industry, hybridisation and utility.
Forecast
Estimates the load curve and renewable generation for the coming hours to plan dispatch ahead of time.
Arbitrage
Calculates the cost of energy in real time based on market price and tariff, and assigns each cycle to the most valuable hours.
Peak shaving
The battery supplies demand peaks so you never exceed contracted power or pay excess charges.
Grid
Receives and follows active and reactive power setpoints at the point of connection, with plant control (Power Plant Controller).
Contingencies
Detects frequency and voltage variations and responds to keep the installation stable and connected.
Diagnostics
Colour-codes the energy behaviour of each device and each hour so that any anomaly stands out.
Operating modes
Each mode has its own priority and state-of-charge margins. The EMS switches between them without intervention.
Self-consumption
Stores the solar surplus and uses it when there is no sun.
Backup
Reserves energy to cover grid outages.
Surplus export
Exports to the grid in the best-paid hours.
EV charging
Powers chargers without upgrading the grid connection.
SoC/DoD limits
Priorities and charge margins per mode.
Input data
The EMS connects to the sources that drive the value of a kWh and recalculates the plan when they change.
Example with a 2 h battery and one cycle per day on the real day-ahead market price.
Range
The same platform in three tiers, depending on the number of assets and the type of grid connection.
| Feature | Commercial and industrialEMS Core | Multi-assetEMS Pro | Utility-scaleEMS Max |
|---|---|---|---|
| Typical installations | Factories, warehouses and microgrids | Large industry, small and mid-sized PV, generators, hybrid systems | PV + BESS plants and grid-connected standalone energy storage |
| What it solves | Self-consumption, peak shaving and backup | Coordinate multiple sources and batteries at a single supply point | Forecasting, market operation and compliance with system operator requirements |
| Works with | Power Pro · Cabinets | Cabinets · Hybrid and STS | Powerbolt |

All tiers include web and mobile dashboards, history, alarms and reports in PDF and CSV. The exact tier is defined with our engineers for each project.
Integration
Native industrial protocols and an open API to connect SCADA, ERP, trading platforms and IoT devices.
Cybersecurity
We treat the EMS as infrastructure: encrypted communications, a firewall and every user with just the permissions they need.
Encryption
Communications over TLS 1.2 / 1.3
Perimeter
Built-in firewall
Access
Role-based user management
Independence
In-house software: no reliance on third parties to operate
We show you the EMS on a call and tell you which tier fits your installation, whether it is an industrial building, a PV plant or a grid-scale BESS.
