A Battery Energy Storage System (BESS) is a technology designed to store and manage electrical energy efficiently. Depending on the specific use case and technical requirements of a location, the total power output of a BESS can range from 10 kW to 10MWs or more.
At its core, a BESS consists of battery cells that are charged and discharged based on precise commands generated by backend algorithms. These algorithms analyze hourly price fluctuations in energy markets to optimize system performance.
BESS projects offer different revenue streams: - trading electricity on energy exchanges, such as Nord Pool; - providing frequency balancing services to support high-voltage grid stability.
EVs & renewable energy causing spikes in supply & demand
Legal pressure for mandatory energy storage
Increasing volatility in energy prices
applications

Virtual Power Plant lets you tap into our pool of batteries and energy sources to trade in energy markets—maximizing profits while we handle the legal and bureaucratic side for you.
Peak shaving
Unplanned demand spikes causing higher energy cost, shave the peak with own reserved energy.
Decarbonisation acceleration
Balance the flow of renewables by storing excess and discharging energy on demand.
Market participation
Buy off-peak electricity and use it at peak times or redistribute it back to the grid for revenue.
Frequency regulations
Stabilise voltage levels by absorbing reactive power and adjusting output.
Infrastructure investment
Postpone costly grid infrastructure upgrades by energy backup for unforeseen events.
Downtime elimination
Build a localised grid that maintain maximum operational availability and operate off-grid.
High-power charging
Realise more power regardless of grid infrastructure limitations with our battery-buffered charging.
SELF-CONSUMPTION
Storing solar/wind energy or cheap grid energy for later use when grid electricity prices are high.
frequency regulation
Responding to grid frequency fluctuations to stabilize the power system.
peak shaving
Reducing electricity consumption during peak hours to lower costs.
energy trading
NordPool, spot markets: storing electricity when prices are low and selling it when they are high.
backup power
Providing emergency power supply in case of outages.
EV charging optimization
Balancing demand and reducing strain on the power grid.
Introducing ENGYcell
Integrated energy storage systems for utility, commercial, and industrial applications.
End-to-end support
ENGYcell builds trading algorithms & produces BESS systems
on spot rates alone, not taking into account other potential revenue streams.
