EXAMPLE OF A TYPICAL CASE A typical gas station in our portfolio:
170 000 kWh annual consumption
49 kW peak consumption in winter before optimization
Technology uses only 4% of total power
Three biggest consumers – HVAC, Refrigerators, Lighting.
Key issues: Extra capacity required for expanding the café and store EV charging – a big challenge in terms of extra capacity Maintenance of equipment especially refrigerators, HVAC, coffee machines is a challenge.
SYSTEM INSTALLATION RESULT AND SOLVED PROBLEMS
Install sensors that measure energy consumption of all major equipment
Install sensors that control key parameters – temperature, humidity, CO2, luminosity, refrigerator temperature, number
of customers, hot water temperature etc.
Connect all major equipment except for technology– HVAC, refrigerators, hot water boilers, coffee machines, lighting – to the Energy Droid controller
Install Solar PV
Replace UPS with a battery energy storage system (optional)
Set up the digital twin
Typical cost of the system Eur 4900 excl. Solar PV and storage
Without Solar PV (lite version) the system typically has a payback period of less than 2 years
With Solar PV a 3–4-year payback period can be achieved.
Withing the lite version we typically retain 50-70% of the saving for investment payback and cost of maintaining the system In an Energy as a Service, we can provide the customer with a 3-5% discount to the current cost of power and achieve a 30% return on the investment The customer also receives several benefits some of which can be charges as a separate product:
Monitoring food storage in refrigerators and refrigerators predictive maintenance;
Coffee machine and other café equipment monitoring
HVAC predictive maintenance
Additional control of gasoline usage
Decreasing peak consumption that allows to connect new equipment and EV charging.
RESULT OF APPLYING THE SOLUTIONS WE PROVIDE Affordability:
Maintenance cost -20%
Resilience:
More capacity for connecting new equipment incl EV charging +30%
Carbon Footprint:
Carbon footprint - 32%
Solar PV output +7%
WHAT SOLUTIONS DO WE HAVE? Internet of Energy platform unifying all assets with machine learning-driven analytics. There are 2 main solutions, the Energy Droid for optimization and the Energy Router for management and storage.
The Energy droid:
IoT-based, end device microgrid model predictive control, energy mgt & DR based on digital twin
Agnostic smart thing mesh connection
Two-level optimization: AI-enabled real-time control + insights for structural efficiency investments.
Smart allocation of storage & DR among applications
Aggregation of small-scale distributed resources.
GAS STATION NANO-GRID — HOW IS WORKS? Reduce power consumption (avg 18%)
Biggest reduction is achieved for HVAC and de-ice systems (up to 50%)
Refrigerators have a significant optimization potential. Refrigerator
Lighting control without dimming saves up to 20%. Dimming can save more but requires additional investment and has long payback periods.
Use all opportunities for energy storages
HVAC, refrigerators, hot water boilers can be used as energy storage devices they represent around 60% of the total gas station power consumption
UPS and reserve diesel can be replaced with an energy storage device. This option becomes attractive when EV charging is considered
Using the storage options allows to reduce the bill by another 5-10% depending on the market rules and tariff plan.
The Energy Droid uses the energy stored to optimize Solar PV operations – energy is stored when output is high and used to cut residual peak.
Microgrid
IoT Equipment control, sensors
Power loads, DR, emissions
Big Data
Analysis/visualization
Microgrid generation and energy flow control
Smart Energy Storage
Mesh optimization: Digital Twin + Machine Learning
HOW DOES IOE HELP SAVE ENERGY? By expending the services provided by our platform to other area including predictive maintenance, support of unmanned technologies and EV charging will allow create significantly value that can be created for the customer and become a strategic partner. Currently energy is just 8% in the gas station cost. However, the platform can address issues for 70%+ of the costs and help increase sales for EVs.
Transportation electrification
EV charging requires high capacity 100-200 kW that is usually not available at existing locations
Gas station face competition from other retailers who can also offer EV charging
EV charging takes longer than filling you tank with gasoline so the customer must be kept entertained
Therefore, non-fuel related services will become even more essential and a convergence between gas stations and other retiail and services will occur.
Unmanned retail technologies
Unmanned technologies in retail become a key competitive advantage. Implementing this technology for gas stations that are stand-alone building often in remote locations requires maintaining climate and equipment control.
