Load Optimization, smart charging to save on your bills

Load Optimization is a service to dynamically balance and manage the power available at the site between several charging stations. In this way it is possible to:

Limit investments needed to the possible increase of power for the installation of the charging infrastructure
Reduce operating costs related to peak power management, achieving up to 35% savings on the bill*.

With Load Optimization, you can limit and manage the total power used for charging stations, and you can save up to 35%* on your bill by reducing the committed power quota.

 

*Savings are conditional on the presence of an active tariff on the power quota. The savings shown here are calculated on the monthly bill per charging point, considering a fleet of 10 identical electric cars, with an average individual consumption of 121 Wh/km, 6.05 kWh of energy required per day, and 50 km/day of driving, each with a nominal power cap of 11 kW. It is assumed that there are equal numbers of charging points per vehicle (10) and charging sessions of 9 hours/day per vehicle, on 5 weekdays (Mon-Fri). The tariff applied for the power share is the BTA6 tariff for other uses (for low-voltage electricity supplies with available power > 16.5 kW) valid for the year 2024, which provides for a committed power charge of €31,3586/kW/year. Savings do not include the cost of the service.

Our Load Management Solutions

Reasons to choose Load Optimization

Save on your bill
Manage electrical charging better, avoiding power peaks.
Limit power increases
Set the power limit of your system, and avoid costly modifications to your electrical system.

Charge Prioritization

In addition to Load Optimization, discover Charge Prioritization, which allows you to distribute charge power among the vehicles in a fleet without ever exceeding the available power limit by setting priority logic. In this way, it is possible to manage the charging process according to the needs of the fleet and choose between different logics, i.e. assigning an arbitrary order of priority to vehicles or charging stations, or prioritising according to the arrival order or departure time of the vehicles.

You can define the charging priority of your vehicles according to order of arrival; the first vehicle to arrive charges the fastest
You can set charging priority according to the charging stations, e.g. you can choose to have the stations in the guest car park charged first and then those reserved for employees
You can set charging priority according to individual vehicles, e.g. choose for vans to charge before cars; or you can define the charging order according to fleet scheduling, i.e. the order in which vehicles leave the fleet.

Tariff Optimization, charging when the cost of energy is optimal

Tariff Optimization makes it possible to plan charging for a fleet of vehicles based on hourly rates, respecting the fleet's charging needs and power limits. In this way, vehicles will be charged at times when the energy component is most advantageous, avoiding peak power charges and guaranteeing up to 40% savings on the bill*.

*Savings depend on the presence of an active tariff on the power quota and an energy tariff with at least 2 time slots. The savings shown here are calculated on the monthly bill per charging point, considering a fleet of 10 identical electric cars, each with a nominal power cap of 11 kW, average individual consumption of 121 Wh/km, 6.05 kWh of energy required per day and 50 km/day of driving. It is assumed that there will be equal numbers of charging points (10) and charging sessions in the evening and at night (from 7:00 p.m. to 4:00 a.m., on the five weekdays (Mon-Fri). The tariff applied for the power quota is the tariff for other uses BTA6 (for low-voltage electricity supplies with available power > 16.5 kW) in force in the year 2024, which provides for a committed power fee of 31.3586 €/kW/year. The energy offer applied is Formidable Luce Impresa by Enel Energia with three-tier tariff (F1, F2, F3) and price of the energy component: PUN (Single National Price defined on a monthly basis and differentiated by time bands) + 0.039 €/kWh. The average monthly PUN for the three bands from November 2023 to April 2024 was taken into account in the calculation. Savings do not include the cost of the service.

FAQ

Load Optimization
Load Optimization Pro
Charging Prioritization
1. What does Load Optimization allow me to do?

Load Optimization allows you to adjust the total power delivered by your charging stations to avoid increasing the capacity of your power network or to reduce the peak power use that will weigh heavily on your bill if you have a power usage tariff. Through the dashboard you can configure a power limit that varies from day to day and also according to the time of day to avoid power outages while charging electric vehicles.

2. Can I also use Load Optimization after installing new charging stations on my site?

Yes, if you need to install new stations on your power network in the future, you simply have to remember to add the new stations via the dashboard in the 'Charge Group' section for which Load Optimization is already active.

3. Is Load Optimization necessary even if I have a dedicated charging station substation?

Yes, in this case, the limit must be configured so that it is equal to 80% of the current limit of the protections above the substation.

 

Substation protection limit : 30 A | System type = three-phase
Configured power = 3 - 0.8 - Substation protection limit - Phase voltage - 0.95 = 3 - 0.8 - 30 A - 230 V - 0.95 = 15kW

1. What is the difference between Load Optimization and Load Optimization Pro

Load Optimization controls the charging stations to make them comply with a limit pre-calculated by the user during activation and does not require the installation of external HW at the charging stations. Load Optimization Pro requires the installation of an additional HW (Waymeter Pro) that monitors the consumption of your site and dynamically calculates the power available for charging stations based on the real-time consumption of other consumers on the same network and the contracted power of your site.

2. I have solar panels; is it possible to use Load Optimization Pro in this case?

Yes. Load Optimization Pro is compatible with photovoltaic panels. The system will take into account any overproduction of your solar panel system, which it will allocate to the charging stations, avoiding energy emissions into the grid (subject to station/vehicle limits).

3. When is it better to use Load Optimization Pro rather than Load Optimization?

Load Optimization Pro is the best choice when the total power absorbed by charges outside the charging stations is comparable with the size power of the charging stations themselves.

1. What is the Charge Prioritization Service

Charge Prioritization allows you to distribute charging power among the vehicles in a fleet without ever exceeding the available power limit by setting priority logics. This makes it possible to manage the charging process according to the needs of the fleet and to choose between different logics, i.e. assigning an arbitrary order of priority to vehicles or charging stations, or prioritising vehicles according to arrival order or departure time.
