Amba Operations GmbH – Cost Efficiency Through the reev Electricity Tariff

For its project in Nuremberg, Amba was looking for an economically viable and future-proof solution to reduce energy costs and peak loads. With dynamic pricing and automated energy management, savings of up to 30% are possible.

Economical. Sustainable. Future-ready.

Amba Operations GmbH is a full--service provider for charging infrastructure based in Munich. The company has been planning, installing and operating charging stations in semi-public environments for six years – from small corporate sites to complex depot solutions. With more than 2,500 charging points under management, Amba supports the professionalisation of electromobility, combining technical expertise with a clear commitment to sustainability.

Challenge: rising energy costs and high administrative effort

As part of a customer project in Nuremberg, Amba faced the challenge of reducing the operating costs of the charging infrastructure and making energy usage more efficient. Until then, electricity had been supplied via traditional fixed-price tariffs – resulting in high administrative effort and limited transparency. Particularly problematic were the so-called RLM-based capacity charges: for larger systems, electrical capacity is measured continuously, meaning that peak loads immediately lead to higher costs. The aim was therefore to find a solution that is economical, automated and future-proof.

Solution: the reev Electricity Tariff – intelligently integrated into the reev Platform

For the customer project in Nuremberg, Amba opted to use the reev Electricity Tariff. The dynamic tariff is based on quarter-hourly exchange electricity prices and is controlled directly via the reev Platform. The automated steering of charging processes is managed through the integrated reev Energy Management System (EMS), which adjusts charging power to current grid and price conditions.

A prerequisite is an intelligent metering system (smart meter) that transmits consumption data to the platform in real time. This enables electricity to be used precisely when it is available, affordable and particularly green – for example at times when a high share of renewable energy is being fed into the grid. This not only shifts consumption into economically and ecologically meaningful time windows, but also directly improves the CO₂ balance of the companies whose charging points Amba operates.

Project overview

• Location: Nuremberg, Ostendstraße (underground car parks Business Tower 1 & 2)
• Charging points: 38
• In operation since: August 2025
• Total consumption: approx. 40,000 kWh (Jan–Sep 2025)
• Savings: up to 30% lower energy costs
• Technology: RLM metering, dynamic pricing, smart meter

Results: measurable cost benefits & operational efficiency

By using the reev Electricity Tariff in combination with the reev Platform, energy costs at the Nuremberg site were significantly reduced. While classic fixed-price tariffs offer little flexibility, the dynamic tariff actively leverages price fluctuations – sustainably lowering procurement costs. The result: up to 30% lower energy costs, optimised load management through automated control, and no additional effort for monitoring or manual adjustments. For Amba as the operator, this means a noticeable increase in daily operational efficiency.

Sustainability: 100% green electricity and eligibility for funding

The reev Electricity Tariff is based entirely on 100% renewable energy produced in Germany. This not only strengthens the sustainability profile of each project, but also fulfils a key requirement for the eligibility of many charging infrastructure subsidies. Amba and its customers therefore benefit twice: through lower energy costs and a demonstrably improved environmental performance.

Outlook: potential for further projects

Following the positive results in Nuremberg, Amba is considering deploying the reev Electricity Tariff in additional customer projects – wherever the technical conditions are met. In future, PV systems and battery storage are also planned for integration in order to link self-generation and consumption even more effectively.

“The reev Electricity Tariff is a real game changer for us. We reduce energy costs, cut administrative effort and make efficiency measurable – all integrated within one system.”
