EMS & Remote Monitoring and Control (RTU)

Two products, one controlled system. EMS optimizes your operating economics; dispatcher control handles the mandatory connection of generators above 100 to the distribution network.

EMS for B2B operations Dispatcher control

EMS

EMS — Energy Management System

Intelligent energy management
for B2B operations

Brainergy EMS coordinates every energy asset — PV, BESS, cogeneration, EV chargers, grid and electricity trading. The goal is minimizing costs and maximizing the value of on-site sources.

Overview of selected services Brainergy EMS provides:

Lower regulated distribution costs

Reduction of reserved capacity / highest measured 15-minute demand
Keeping operations within grid limits (e.g. reserved capacity)
Real-time peak shaving

Maximum use of on-site sources

Maximizing output from PV, wind, micro-hydro and other renewables
Storing on-site generation when day-ahead prices are low
Using stored energy during high purchase-price hours
Maximum utilization of the on-site battery storage

Energy-flow control

Coordinated control of every managed energy asset
Trading on the day-ahead market — buy and sell
Targeted export of surplus during high feed-in prices
Load manager — control of AC and DC EV chargers
Electricity sharing IN/OUT across delivery points to save the energy component
Backup against grid outages

Ancillary services (frequency / voltage support)

Flexibility aggregation for frequency and voltage stabilization in the transmission system
Commercial flexibility (intraday) and correction of trading imbalances
Additional revenue from battery storage and flexible assets

Real-time monitoring & data archive

Continuous collection, visualization and archiving of data from every connected technology. Configurable archive resolution (1 min / 15 min / daily / monthly / yearly) for audits, efficiency reviews and regulatory reporting.

Real-time energy flows
Battery power, SOC, SOH
Voltage and current parameters, inverter states
Communication with the distribution network
Alarms, faults, operating states
Archive at 1-min / 15-min / daily / monthly / yearly resolution

Standard EMS delivery

Optional services (scheduling calendar, tariff model, Profit Optimizer, detailed BESS/PCS monitoring…) on request.

Protected against cyber attacks

Czech solution, NIS2-ready, data never leaves the EU

Software and hardware developed in the Czech Republic, manufactured in the Czech Republic
Data stored exclusively in Czech data centers
Operational data is never transferred or stored outside the EU
Architecture built around NIS2 and critical-infrastructure cyber-security principles
Remote vendor access to technologies is blocked
Strict identity, role and permission management with full auditability
Encrypted communication following best practices
Continuous 24/7 support for key services

Dispatcher control

Mandatory control of generators above 100
for connection to the distribution network

Dispatcher control provides continuous supervision and the transfer of key data to the distributor's dispatch center for grid stability. The distribution-system operator can adjust renewable output to match real-time consumption and grid conditions.

Designed for PV, micro-hydro, wind, BESS, cogeneration units and diesel generators.

Approved for:ČEZ DistribucePREdistribuceEG.DLDS
