Smartplug Energy Optimisation by Wirtek

Cut energy waste, with fast, proven savings

Real-time insights
Lower operating costs
CSRD-ready data

Why now?

Energy prices keep climbing and ESG rules are tightening. Retailers are expected to show real, verifiable reductions, not vague commitments.

Every unmanaged refrigerator, cooler or display case is leaking money day and night. The quickest wins come from tackling the obvious waste first.

Opportunity for you

Most retail chains still run non-critical refrigeration equipment 24/7, even when stores are closed and no cooling is needed. That is pure standby loss.

With smart, automated shutdowns and real-time monitoring, clients can unlock 25–30% savings within months, improve operational transparency, and support CSRD-ready reporting across distributed sites.

Solution at a glance

Self-install Wi-Fi smartplugs configure automatically through the cloud. No electricians. No infrastructure work.

Electricity dashboard

Real-time monitoring and insights

Continuous visibility into energy usage, costs, and emissions is provided at device level through dashboards, alerts, and historical data. This enables early detection of anomalies, better understanding of usage patterns, and faster corrective action.

eCop customization

Visual energy feedback and customisation

LED indicators can be fully customised to display colours based on energy consumption, electricity price, or CO₂ intensity, turning each device into a simple, visual signal of performance. 

Sensor scheduling tool

Elimination of energy waste

Unnecessary consumption is reduced by automatically shutting down non-critical equipment when not in use, particularly across refrigeration and auxiliary loads. This removes standby losses and excess runtime, typically delivering energy savings in the range of 25-30% without impacting operations.

Map of sensors

Scalable rollout across distributed sites

Deployment is simple and does not require electrical installation, making it suitable for large-scale rollout across retail chains and multi-site operations. Centralised control allows automation rules and policies to be applied consistently across all locations.

Info per location

Integrated platform and reporting

Hardware, cloud platform, and APIs are combined into a single system that supports monitoring, automation, and integration. Energy data can be used for optimisation, cost tracking, and ESG reporting, ensuring consistency across the organisation.

List of sensors

Device-level energy control

Smart plugs enable direct measurement and control of individual appliances, providing clear visibility into actual energy usage at the device level. Each unit becomes traceable and controllable in real time, making it possible to identify inefficiencies and act on them immediately without changing existing infrastructure.

Automation tree

Automated optimisation based on real conditions

Energy usage is continuously optimised based on schedules, electricity prices, and CO₂ intensity. Consumption is shifted away from peak cost and high-emission periods, ensuring more efficient operation without manual intervention and with consistent behaviour across sites.

Success case

Saving energy in retail stores

Smartplug Energy Optimisation by Wirtek have measured energy savings between 31,6% and 49,6% on refrigerators cooling down drinks. 

A retail store has invested in 400 smart plugs in a first-step integration supplied to 20 large stores.
Investment is 75.168 EUR including 5 years of platform operations in the Wirtek IoT Suite.

Key results

  • 35-year savings are 350 000 kWh or 32 tons of CO₂ emissions

  • ROI is between 0.5 to 1 year depending on the refrigerator type

Ideal for

Retailers and grocery chains

Organisations running multiple stores with extensive refrigeration footprints and rising energy costs.

Fuel-station and convenience chains

Networks managing scattered service stations with mixed refrigeration loads and no central control.

Foodservice and hospitality

Operators running small-format locations with high energy spend from secondary refrigeration.
