Don't let your energy go to waste!
Save it with energy storage
Energy Storage Systems in Luxembourg
⚡ How an Energy Storage System Lowers Your Electricity Bills
- Maximize your solar energy use – Instead of exporting excess power to the grid for minimal profit, store it for evening or night-time use. Keep more of your own clean energy.
- Reduce peak demand = stabilize your costs – Our battery storage systems smooth out energy consumption peaks (peak shaving), helping you avoid higher grid fees and protect against energy price increases.
- Ready for EVs and heat pumps – The system balances short-term load spikes when charging your electric vehicle or running your heat pump. Works seamlessly with dynamic tariffs and smart schedules.

Independence and savings
The most important benefits of energy storage
Independence and energy security for your home and business.
Stay powered when the grid goes down. A right-sized battery gives automatic backup, uses more of your own solar, and sharply cuts grid draw—protecting you from rising energy prices. Choose independence with our energy storage & backup solutions.
Cheap electricity at any time of the day or night
Buy cheap electricity at night, use it during the day, and pay less. A home battery also stores your PV surplus, so you rely less on the grid when solar is low. Save more and gain independence with our energy storage solutions.
Increasing auto consumption and relieving the energy network.
Boost your self-consumption and buy less at peak prices. A home battery stores your PV surplus and smooths peak demand, so you use your own electricity when you need it—not when the grid dictates. Take control with our energy storage solutions.
Subsidies for energy storage – attractive programs
Unlock subsidies to cut your battery costs and boost ROI. Current programs can cover a significant share of purchase and installation—often 25–50%. We’ll check your eligibility, prepare the paperwork, and maximize your benefit so your storage pays back faster.
Flexibility in expansion – Easy to adapt to your needs!
Start small and expand anytime. Our modular batteries are sized to your needs for maximum efficiency. Planning an EV charger? Storage absorbs the extra load and smooths peaks, so you charge reliably without costly grid upgrades.
Intelligent energy management
Manage energy smartly and cut costs. Intelligent modes charge when power is cheap or solar is abundant, then discharge when prices rise. Automations can run devices when the battery is full, and stored PV powers your home at night instead of exporting—lower bills, higher self-consumption.
