Capabilities · Storage
By removing grid capacity limits, on-site Battery Energy Storage Systems (BESS) give businesses, solar farms, and industrial sites the power resilience and independence to manage their energy on their own terms.
01 · The problem
Electricity has always had to be generated at the moment it is consumed. That constraint shaped every grid built in the last century, and it is the constraint that storage removes. Four pressures have turned it from an engineering curiosity into a commercial necessity.
Generation
Photovoltaic output peaks around midday. Household and commercial demand peaks in the early evening, after the sun has dropped. Without somewhere to put the surplus, it is curtailed, and the evening peak is met by conventional plant instead.
Connection
A new or upgraded connection takes years and carries significant cost, and in constrained areas it may simply be unavailable. Storage lets a site draw more power at peak than its connection is rated for, by charging quietly while the connection sits idle.
Stability
As conventional generation retires, the system loses the rotating inertia that used to absorb frequency disturbances. Batteries respond in milliseconds, far faster than any thermal plant, which makes them well suited to the job that inertia used to do.
Isolation
A system with limited interconnection cannot import its way out of a shortfall or export a surplus. Every imbalance has to be resolved locally, which puts a high premium on fast response and on capacity that can be sited close to the load.
02 · The case
A battery system rarely earns its keep on one benefit alone. Most projects stack several of the following, and the balance between them decides how the system is sized and how it is controlled.
Where a tariff prices the highest half-hour of the month, discharging across that peak cuts the charge directly. The battery pays for itself on the bill rather than on the meter.
Added load, a new production line or a bank of chargers can be served from storage at peak, deferring or avoiding a connection upgrade and the wait that comes with it.
Midday surplus is held until it is worth something instead of being exported at a low price or curtailed outright, which raises self-consumption and shortens payback on the array.
A system configured for seamless transfer holds critical load through a disturbance with no break, and can carry a site through an outage or support a generator while it starts.
Where the market allows it, unused capacity can be offered as frequency response or reserve, turning an asset bought for one purpose into a second income stream.
The inverter that moves the energy can also support voltage and supply reactive power, smoothing the disturbances that heavy or intermittent loads push back into the network.
03 · The record
Electromatic has designed, built and commissioned electrical distribution and control equipment since 1969, and delivers battery storage on the same basis — engineered, assembled and tested in house, then commissioned on site by the people who built it.
