Mobile emergency power for supermarkets

Protect your stock during local power outages. Prepare suitable stores for shared mobile generators or batteries.


The working group

We help grocery retailers protect their stock and keep their stores operating during local power outages. During the power outage in Berlin in January 2026, we were involved in providing emergency power to affected supermarkets.

The concept in three steps

How to prepare your store for power outages

Decide who acts, what keeps running and how mobile equipment reaches the store.

Keep refrigeration running

Prioritise chilled and frozen stock. Set temperature checks and agree when to move goods or close the store.

Decide before the outage

Agree which stores get equipment first, who activates the plan and which functions can continue.

Organise staff and logistics

Coordinate equipment delivery, placement, fuel, staffing, communication and security.

Prepare the connection

Have the connection, switching and protection installed and tested for the equipment that needs emergency power.

Risk assessment and deployment planning

How do you choose the right stores?

For retail networks with thousands of stores, priorities must be set before an outage to determine which locations receive power first. Otherwise, ad-hoc triage is needed: deciding under time pressure which store receives a generator. Check in advance whether a mobile generator can be operated at the site. Our risk assessment tool weighs practical conditions, stock value, security and importance to local food supply across your network.

We have a risk assessment tool. We use it to assess the suitability of your stores and recommend which should be equipped first.

Have my supermarkets assessed
Space and access
Check equipment space, cable routes, the connection and site restrictions. Keep access for emergency services clear.
Delivery time
Check how quickly equipment can arrive, including when several nearby stores lose power.
Logistics
Agree who delivers the equipment, where it will stand and who supports it throughout operation.
Store priority
Weigh the effort required to equip the store, stock value, risk of unrest and local food supply. Different criteria may favour different stores.

PowerLock and site preparation

Prepare your store for mobile power

With PowerLock, you can connect a mobile generator or battery to your store. Equipment from different providers can be used if it meets the store’s electrical requirements.

A qualified electrician plans the connection, installs the switching and protection equipment, tests the installation and approves it. Authorised personnel can then connect preconfigured equipment without an electrician on site. (The applicable legal provisions must be observed.)

Install and test

The emergency power supply is sized for the selected operating level. A qualified electrician installs and tests the connection point, including switching and protection equipment.

Connect

Authorised personnel can connect preconfigured generators or battery systems to the prepared connection point without an electrician on site. (The applicable legal provisions must be observed.)

Supply

Power can be distributed through separate circuits: refrigeration, checkout/IT and lighting, through to the in-store bakery. This puts your prepared operating plan into action.


Three operating levels

Protect the goods first

Refrigeration comes first. Whether trading can continue depends on power, staff, IT and payment systems.

  1. 01

    Refrigeration only

    Keep chilled and frozen goods at the required temperatures while the store stays closed.

  2. 02

    Limited trading

    Add lighting, checkouts, payments and IT for an agreed reduced service.

  3. 03

    Full operation

    Restore other functions where power, staff, safety and the operating plan allow.

Limit the financial loss

When chilled and frozen goods spoil, you lose their value and pay for disposal and replacement. Mobile emergency power can limit these losses. Our target is to operate the agreed store functions on emergency power for 72 hours. This gives time to arrange further generators and fuel, relocate goods or resume full operation. Continuing on emergency power until the grid operator restores supply is another option.

Criminology, Food Defence and the neighbourhood

Protect staff and goods

Crises can lead to looting and unrest. Our criminologists include these risks in the site assessment and develop measures to maximise the safety of staff and goods. These measures form part of the overall plan.

Providing a place to charge phones is a simple way to involve the neighbourhood.


Frequently asked questions

We help you decide which stores to prepare first and what they need. Specialists from different fields develop the playbook and plan site preparation together. Equipment can be arranged through our partners.
