COR.stor now available — see what it can do for you. 5 + 5 years’ battery warranty. Up to 2.2 kW of your own winter power while heating.

Water and wastewater associations

Treatment plants and pumping stations need power around the clock.

Blowers, pumps, controls and telemetry run continuously. COR.stor stores the power from your PV system, reduces grid purchases and can keep key loads supplied in a grid outage.

Steady load instead of office hours.

A treatment plant or pumping station draws power almost evenly around the clock — aeration, pumps, screens, controls. If the grid fails, it shows within hours.

What matters to you

Security of supply for the critical parts of the plant, predictable energy costs and more of your own power from the PV system on site.

When the question comes up

  • High continuous consumption around the clock
  • PV system on site or planned
  • The backup power concept is being revised
  • The generator is old or rarely runs
  • Rising energy costs in the association budget

Calculator

What does COR.stor do for your plant?

Enter your plant’s own values — no defaults: electricity use, PV, energy price. For backup power, what counts is the continuous load that must keep running in a grid outage.

kWh per year

The plant’s annual consumption from the electricity bill. The calculation assumes an even load around the clock.

ct/kWh

Energy price including grid charges, net. Leave empty and we use our default.

Storage size

Each COR.stor offers 70 kWh of usable capacity, expandable to 210 kWh. Larger storage is designed individually.

Your result

Enter your plant’s electricity use and we will calculate.

Demand charge on your electricity bill?

COR.stor can shave load peaks. How much that brings depends on your load profile. Send us the 15-minute values from your grid operator’s customer portal — we will work it out for you free of charge.

Store

COR.stor

COR.stor offers 70 kWh of usable capacity, expandable to 210 kWh, takes in PV power and typically takes over within 20 ms in a grid outage. Larger storage is designed individually for the plant.

Control

COR.app

The controls distribute PV power and storage as needed; remote maintenance can report faults automatically to COR Service. An existing backup generator can be integrated.
