Electrification not only changes vehicles and infrastructure, but also creates new requirements for energy supply. Electricity tariffs, grid charges and price signals directly affect fleet operating costs. Through detailed analysis of existing energy contracts, tariff structures and load profiles, we identify optimisation potential. We examine how usage duration, peak loads and grid charges shape annual costs – and where savings can be achieved. In addition, we simulate scenarios for dynamic markets: How will prices and fees evolve in the future? What flexibility potential do charging windows, storage use or load management offer? The goal is to align electricity procurement and charging infrastructure to reduce costs, minimise risks and take advantage of market opportunities. This provides companies with strategies that are economically viable today and robust for the future.
