Solution

Peak Shaving

Battery systems discharge during demand peaks to reduce grid demand charges for factories and commercial sites.

The challenge

The cost of demand peaks

On commercial tariffs, a few minutes of peak demand can set the demand charge for the whole month.

  • Short load spikes from machines, compressors or chargers inflate the monthly demand (kW) charge.
  • Demand charges can be a large share of an industrial electricity bill, independent of total consumption.
  • Grid connection upgrades to handle peaks are slow and expensive.

How it works

How peak shaving works

The battery discharges precisely during demand peaks and recharges off-peak.

  1. 01

    Load monitoring

    The EMS/HEMS continuously measures site demand against your target threshold.

  2. 02

    Peak detected

    When demand approaches the limit, the PCS begins discharging in milliseconds (≤20 ms response).

  3. 03

    Battery covers the spike

    The PCS supplies the peak — with 1.5 Pn / 10 s overload headroom — so grid draw stays below the threshold.

  4. 04

    Off-peak recharge

    The battery recharges from the grid or PV during low-tariff periods.

FAQ

Frequently asked

How much can peak shaving save?

Savings depend on your tariff and load profile. Sites with sharp, predictable peaks typically cut demand charges most. We model your case from interval meter data before quoting.

Do I need solar for peak shaving?

No. Peak shaving works with a grid-charged battery alone, and can be combined with PV for additional savings.

What payback can I expect?

It depends on your demand-charge rate, peak profile and any price-arbitrage spread. Comparable European arbitrage retrofits have reached roughly 1-year payback; we run a site-specific ROI calculation from your tariff and interval data before quoting.

Can SAKETE deliver at grid scale?

Yes. SAKETE was awarded 1.1 GWh of standalone BESS in Bulgaria’s Next Generation EU RESTORE programme, alongside C&I-scale cabinet and container systems.
