Preflet Energy Management
Preflet's LEO platform uses AI and real-time spot electricity prices to optimise refrigeration and HVAC setpoints across multi-site retail portfolios — the intelligence layer that complements ELIoT's plug-in battery hardware.
AI-Driven Energy Management, Built for Multi-Site Retail
LEO goes beyond a standard energy management system — it prioritises the highest-value action at every site, every half-hour, using live market signals instead of passive monitoring.
Dynamic Spot-Price Setpoints
Reads day-ahead electricity prices (via ENTSO-E / Energinet) and adjusts refrigeration and HVAC setpoints to shift load into the cheapest, cleanest windows.
Portfolio-Wide Visibility
Streams 15-minute interval data and 40+ submetering parameters across every site into one organisation-level view.
Automated Compliance Reporting
ISO 50001-aligned reporting with area-manager benchmarking, in-store displays, and Scope 1/2/3 emissions tracking — no manual spreadsheets.
Danish Supermarket Chain, Modelled Portfolio-Wide
Results modelled for a central operations team of just 6 people managing 1,000 stores across Denmark's DK1 and DK2 pricing zones.
Energy Savings
Spot-price-driven setpoint optimisation on refrigeration, without compromising food safety.
Operational Time
Less time spent chasing faults and manually adjusting equipment store by store.
Store Manager Calls
Fewer escalations to head office as issues are caught and resolved centrally.
Refrigeration cycles are optimised within tight ±1°C cabinet temperature and ±1% pressure tolerances — freezers are never touched, and food safety is never compromised.
From Market Signal to Site-Level Action
LEO turns a live electricity price feed into automated, food-safe equipment control — then reports the result.
Reads the market
Pulls day-ahead spot electricity prices and weather/heating-demand data for every site, every day.
Optimises setpoints
Pre-compresses refrigeration during low-price windows, holding cabinet temperature and pressure within tight, food-safe tolerances.
Reports & improves
Delivers automated monthly and annual KPI reports, solar performance alerts, and ROI tracking on efficiency investments.
Integrates With What's Already On Site
LEO plugs into existing metering, controls and market data — no rip-and-replace required.
ENTSO-E & Energinet
EU-wide day-ahead spot electricity price feeds driving every setpoint decision.
Modbus TCP
Smart meters, energy analyzers and HVAC / refrigeration controllers, connected directly.
MQTT
Preflet's own broker on Microsoft Azure for real-time, low-latency device messaging.
AzureMaps & Webhooks
Geospatial and weather data feeding heating-demand models, plus HTTP webhooks for custom alerts.
