SmartPuls

Electricity prices directly in your SCADA

SmartPuls gives your PLC access to electricity prices, temperature, and precise time – without network connections, API integrations, or complex setup.


What is the box?

SmartPuls is a small unit mounted directly on the DIN rail inside the electrical panel. It has a built-in SIM card and automatically delivers data to your control system – without the need for network access, IT involvement or complex setup.

All communication takes place via a single 24VDC digital output, which is connected to a PLC input. This makes the solution simple to install and easy to use in existing automation systems.

With SmartPuls, you can easily start and stop equipment, optimize operation and document energy consumption – fully automatically.

Data delivered to your system:

  • Electricity prices hour by hour – today and tomorrow
  • Weather data for the local location via GPS – hour by hour, today and tomorrow
  • CO₂ intensity in g CO₂/kWh every 5 minutes – for display in SCADA and documentation in ESG reporting
  • Current time – used as a precise time server
  • Error signal in case of missing data
  • Simple, secure and NIS2-compatible data delivery

Get a quick overview of how much you can save with SmartPuls. Adjust the sliders and see how electricity costs can be reduced by avoiding the most expensive hours of the day.

Quick start: Example figures — adjust them to match your own plant
Daily savings 240 DKK
Monthly savings 7.200 DKK
Annual savings 86.400 DKK
Estimated CO₂ savings/year
0 kg This is roughly equivalent to a passenger car driving almost twice around the Earth.
Payback
Calculation: power × operating hours × shiftable share × flexibility × price difference
The payback calculation is based on SmartPuls Complete 4G at 5,450 DKK plus 12 months of subscription at 99 DKK per month, excluding VAT.
The CO₂ estimate is based on an assumed difference of 50 g CO₂/kWh between expensive and inexpensive hours — the actual difference varies from hour to hour.

Installation of SmartPuls on a DIN rail inside an electrical panel
Installation in practice

Simple installation in the electrical panel

SmartPuls is mounted directly on the DIN rail and connected to the PLC via a single digital 24VDC signal. The built-in 4G connection means that no network access to the automation system is required.

  • Direct DIN-rail mounting
  • One digital 24VDC signal to the PLC
  • No network access to PLC or SCADA
Suitable for both new plants and integration into existing electrical panels.

Examples from different plant types

See how SmartPuls can be used in district heating, biogas and wastewater applications.

  • Start and stop electric boilers and heat pumps based on electricity prices — minimize operating costs during peak-price hours.
  • Dynamic load control: Scale heat pumps, pumps or electric boilers in steps according to the price level, for example 100% / 50% / 0%.
  • Electricity consumption logging: Get an accurate picture of when and how much electricity is used — and what it costs.
  • Precise calculation of electricity costs: Combine operating times and electricity prices to analyze the efficiency of individual machines or processes.
  • Automatically switch between heat-producing units based on electricity prices — for example between a heat pump and gas or wood-pellet boilers.
  • Time-based operation: Synchronize the PLC with precise time — essential for time-based switching and documentation.
  • Temperature-based control: Adjust start, stop and load steps for heat pumps according to both price and outdoor temperature.
  • Gas-engine control: Start and stop gas engines according to current electricity prices and maximize the value of electricity production.
  • Compressors and pumps: Optimize the operating times of energy-intensive units — run them during low-price periods and avoid peak loads.
  • Gas storage: Postpone the use of stored biogas until periods with higher electricity prices, when production provides the best return.
  • Time-based PLC operation: Synchronize the PLC system with the built-in time server — and avoid deviations in control logic.
  • Automated energy control: Activate functions automatically during hours with low electricity prices — without manual intervention.
  • Tank mixing: Reduce or postpone tank mixing during peak-price hours if the process allows it — and save energy.
  • Weather-compensated operation: Use local temperature data to adjust strategies for gas-engine loading or heat recovery.
  • Pump control: Adjust pumping in sewer systems and pumping stations according to electricity prices — and postpone non-critical pumping to low-price periods.
  • Mixing and aeration: Run aeration tanks and mixers intensively when electricity is inexpensive — and reduce operation during peak-price periods.
  • Sludge dewatering and transport: Schedule dewatering, polymer dosing and sludge pumping for periods with low electricity prices.
  • Carbon filters and UV systems: Adjust the operating time of UV disinfection and carbon filters where operationally appropriate.
  • Heat pumps: Optimize the operation of wastewater-based heat pumps according to the price level — and reduce energy costs.
  • Temperature-based aeration: Adjust the operation of mixers and aerators according to water temperature and outdoor temperature.
