Spread the same energy
The vehicles get the energy they need by departure, spread across the hours they are parked instead of all at once.
Product · Plan
Lower grid fees and a lower price for every kWh
Two parts of the bill respond to when you charge: the grid fee, which follows your single busiest quarter hour, and the energy price, which changes through the day. The plan works on both at once.
Peak shaving
Do not set a new peak
Many grid tariffs bill the busiest quarter hour of the billing period. One evening of everyone charging on arrival is enough to set it.
Respect the peak already set
If the site has already set a peak this period, the plan keeps the connection at or below it.
Without leaving vehicles short
A hard cap alone holds power back without knowing departure times. The plan knows when each vehicle must be ready.
On the example day
Dynamic load management draws up to 277 kW at the connection. Holding it at the depot's own 150 kW with a cap brings the peak down, but leaves 6 vehicles short at departure. The RiDERgy plan also stays at 150 kW and leaves 1 vehicle short.
Energy procurement optimization
Charge in the cheap quarter hours
Prices are not flat. Charging follows whichever price signal applies to the site, not spot prices only.
Day-ahead prices
Spot prices move every 15 minutes. Moving charging into the cheap ones lowers the cost per kWh.
Dynamic tariffs
Dynamic tariffs follow the day-ahead market. Many countries are beginning to introduce them under EU law.
Time-of-use tariffs
The most common tariff today. The plan charges in the cheaper windows the tariff offers.
On the example day
Charging costs 30.1 ct/kWh with dynamic load management, 27.9 ct/kWh with the 150 kW cap and 24.0 ct/kWh with the RiDERgy plan.
Routes and charging
Plan the routes together with the charging
What a kWh costs depends on when a vehicle is plugged in, and that depends on the route it drives. With PTV Logistics, a RiDERgy partner for route optimization and transport planning, routes and charging can be planned as one.
Planning phase
Routes set the departure and the energy need
Optimized routes fix when each vehicle leaves and returns and how much energy the tour needs. The plan uses those times to pick the cheap quarter hours.
Operational phase
A changed route changes the plan
When a route or a departure time changes during the day, the next plan, recalculated every 15 minutes, starts from the new situation.
Example depot with invented fleet, buildings and fuses and real EPEX day-ahead prices, 20 January 2026. One example day, not a forecast for your site.
From plain load management to the plan
The same example day, step by step: a cap brings the peak down but costs vehicles, and the plan keeps both low.

Planned together, not one at a time
Cheap quarter hours are often the same ones in which everyone would charge. Chasing price alone creates the peak, and capping peaks alone ignores price. The plan weighs both with departure times, solar and storage, so one does not undo the other.
Questions about prices and grid fees
What tariffs do you optimize?
The most common tariff we currently optimize is time-of-use; however, our algorithms also work with dynamic tariffs, which change regularly throughout the day based on the price of the day-ahead electricity markets. Ask us about existing tariffs in your country.
What are dynamic tariffs and how can they help me save?
Dynamic tariffs change regularly throughout the day based on the price of the day-ahead electricity markets. By using mobility data with our energy management software, we schedule vehicle charging when dynamic tariff prices are lowest, resulting in even greater savings potential.
Does this work if my tariff has no demand charge?
Yes. Price optimization and keeping every fuse within its rating do not depend on a demand charge. Where there is one, the plan also avoids setting a new peak.
