Containerised & cabinet ESS
From 215–261 kWh AIO cabinets to 5 MWh containers and 10 MWh / 5 MW blocks for MW-scale trading.
Solution
Energy Arbitrage & Trading
Charge batteries when prices are low and discharge when they peak, capturing day-ahead and intraday price spreads.
The challenge
Turning price volatility into revenue
Volatile day-ahead and intraday markets reward storage that can buy energy cheaply and sell or self-consume it when prices peak.
- Midday solar and off-peak hours push wholesale prices low, while evening peaks are expensive — a spread storage can capture.
- Exporting PV at low feed-in tariffs leaves money on the table versus time-shifting it to high-price hours.
- A bankable trading case needs high round-trip efficiency, cycle life and a system that can charge and discharge daily for years.
How it works
How arbitrage works
The EMS follows price signals to charge low and discharge high, with optional dynamic-tariff automation.
- 01
Price signal
The EMS reads day-ahead / intraday prices (or a dynamic tariff) and builds a charge/discharge schedule.
- 02
Charge low
The battery charges from cheap grid power or surplus PV during low-price windows.
- 03
Discharge high
Stored energy is discharged to the site or grid when prices peak, up to 6 daily charge/discharge windows.
- 04
Repeat daily
314 Ah LFP cells rated for 8,000+ cycles sustain daily cycling across the project life.

Representative SAKETE storage projects in this application.
Northern Europe 6.25 MW / 12.5 MWh
125 × 50 kW / 100 kWh · DC-coupled
Storage added to an existing 10.75 MWp on-grid PV plant with smart dynamic price trading and up to 200% PV oversizing. Compact, fast install for Nordic terrain — ~8-month payback.
Eastern Europe 1.6 MW / 3.44 MWh
16 × 100 kW / 215 kWh · AC-coupled
Retrofit to an existing 10 MWp PV plant — ~1-year payback from price arbitrage.
Eastern Europe 875 kW / 1.827 MWh
7 × 125 kW / 261 kWh · AC-coupled
Retrofit to a 5 MWp PV plant — ~1-year payback from charging low and discharging high.
FAQ
Frequently asked
Can the system trade on the day-ahead and intraday markets?
Yes. The EMS can charge and discharge against price signals or a dynamic tariff, with up to 6 charge/discharge windows per day. Market access itself is arranged through your energy supplier or aggregator.
Is arbitrage compatible with PV self-consumption?
Yes. The same system can prioritise self-consumption and use spare capacity for arbitrage, configured per site.
What payback can we expect?
On strong price spreads SAKETE retrofit projects in Europe have reached around one-year payback, but this depends on your market, tariff and cycling — confirmed in the project quote.
